IMPORTANT FIRST FIRING MUST BE A LOW INEFFICIENT FIRE FOR THE MINIMUM TWO HOURS TO DRY
THE REFACTORY SILICON CARBIDE SLOWLY: FAILURE TO DO SO WILL CRACK THE APPLIANCE.
PLEASE READ THIS ENTIRE MANUAL BEFORE YOU USE YOUR ROOM HEATER. FAILURE TO FOLLOW INSTRUCTIONS MAY RESULT IN PROPERTY DAMAGE, BODILY INJURY OR EVEN DEATH. 1. INTRODUCTION We would like to thank you for choosing our product and wish you every success and happiness with your Ecco Stove®. Your stove is tested to EN15250 and EN13240 when burning wood logs only. Please read these instructions. The installation and use of the Ecco Stove is regulated by installation regulations specific to the country it is to be installed in (building regulations in the UK). The installer must be aware that all local regulations, including those referring to National and European standards need to be complied with when installing the appliance. Not every stove can be connected to every existing chimney. Your installer must check the efficiency and suitability of the chimney to ensure its suitability for use. If the two are not compatible this can lead to poor burning and blackening of the glass. The local authority will be able to inform you of the type of fuel you are allowed to burn in the area the stove is to be installed. Currently the Ecco stove is tested for wood burning but wood maybe burned in a smokeless designated zone provided it is operated to the following instructions (see Item 12). Additionally your installer will be able to advise you on the size of stove required for the space you have. You will need a sufficient flow of oxygen into the room for combustion, which may require a fresh air vent to be installed into the room where the appliance will stand. Some of the technical information you or your installer require is included in this handbook. Our information leaflet and a technical data table are at the rear of the Ecco Stove catalogue for your guidance.

2. PURPOSE Typical wood burning Stoves are intended as a secondary form of heating. The Ecco Stove is designed to heat much more of the house as primary and/or secondary heating. Please ensure the Ecco stove is used within the parameters laid out in this manual. 3. MATERIALS The Ecco Stove is constructed primarily from a mix of Silicon Carbide, a material that has a high affinity to absorb heat but radiate it slowly and gently, therefore permeating greater distances within the home than conventional materials of stove construction. The Ecco Stove has double pass flue ways prior to exit of flue gasses to exhaust, to enable the maximum of heat to be extracted and utilised within the appliance and hence the air space within which the appliance is situated. Radiant heat is emitted by heat from the external surfaces and initial heat from the front glass door panel. 4. FLUE OUTLET Your Ecco Stove is only delivered with a top flue exit due to the construction of the appliance and contraflow channels. If the installation demands, a 45° elbow can be taken directly from the top of the stove and back into the chimney Brest and hence the chimney flue. The flue pipe must include a soot door/ access plate within 200mm of stoves top for stoves flue ways and chimney flue cleaning. (The flue outlet is 150mm.)
The Ecco Stove must have its own dedicated flue; it cannot be shared with another appliance.
Do not connect this appliance to a chimney serving another unit.
Access must be provided for cleaning the chimney and stove/connector pipe. 5. GLASS The glass panel provided with your stove is deemed a consumable and may need to be replaced during the life of the stove. Consumables are not covered by the manufacturers guarantee. In the event of having to replace the glass in the stove please note that any fixtures should not be more than hand tight. If captive nuts are used on your stove; please take care not to over tighten them. Do not over fill the stove as damage or breakage of the glass is normally associated with the door being closed onto a larger log than the firebox can accommodate.

Patent pending USA, Canada, Europe & Russia | UK Patent nos: 2467433 & 2498883
6. CLEAR GLASS OPERATION
Blackening of the door glass results from poor quality fuel (unseasoned wood) and initial firing until the stove has reached its optimum working temperature.
Chimney draft, if less than 0.06 inches water gauge will impair the stove performance and hence its capability to keep the door glass clean. Your installer will check this for you.
The whole stove body should be a minimum of 150°C to enable the air wash to operate satisfactorily on the inside of the glass face. (200°C is the optimum operating temperature).
Do not load logs with the end grain pointing toward the glass as this will result in excessive glass blackening. Always arrange the logs in a wigwam fashion within the firebox. We cannot guarantee that the stove glass will not blacken but correct usage of fuels and operating temperatures will usually clean the glass throughout the burn.
7. AIRATED BACK PLATES The back panels (pre-drilled vermiculite and ceramic coated panels at the rear of the stove) are consumables and will deteriorate in use. The panels are not covered by the manufacturer’s warranty. Damage can be caused by excessive firing but more usually by logs being smashed against them when loading stove. Loading must be carried out with care. 8. ASH GRATE The grate within your Ecco Stove is made from cast iron being a highly durable material providing ash is not allowed to sit in the grate bars from the ash tray beneath. Ash removal is recommended before the grate bars become flooded with ash. The grate is easily removed by simply lifting it out through the opened glass door.

9. ROPE SEALS Regular maintenance of the stove is in part related to rope seals. Seals between the sections are factory fitted and may remain in place without maintenance unless the appliance is stripped and moved, at which time all compressive seals between sections must be replaced with like for like diameter rope or flat tape as fitted to the stove at the time of its construction. Door/ash pit/cleaning plug and hob cleaning plug seals should be replaced when showing signs of wear or every two years whichever comes first. Rope seals are not covered by the manufacturer’s warranty. 10. FINISHES For the first three to five firings your stove will produce what would appear to be toxic fumes and is often mistaken for smoke leaking out of the appliance. This is just the paint curing onto the appliance.
Please ensure that the room is adequately ventilated and allow the smoke to dissipate in due course without adding more fuel at that time.
If the paint finish should change colour due to mis-use or over heating you should approach your Ecco Stove dealer who will provide you with spray aerosol paint in the appropriate colour to make a paint repair.
The Ecco Stove is produced from a self coloured material and as such variations in colour and texture of that material may be evident but adding to the uniqueness of the product, unless ordered as a pre-factory painted or as ready for paint on site finish to co-ordinate with home decor. 11. AIR CONTROLS Your Ecco Stove has three systems of air inlets for combustion but only one adjustable user control for ease of use (being the ash pit drawer). All other air inlets are fixed and non adjustable. 11A. TERTIARY AIR MODEL 850 and 678 The aerated back plates provide tertiary air from a permanently open air inlet at the back of the stove. This air supply has no facility for being closed and is set permanently open. Tertiary air is introduced to put the level of the air wash/baffle to re-combust volatiles before they exit unburnt into the double pass flue ways and chimney flue.

Patent pending USA, Canada, Europe & Russia | UK Patent nos: 2467433 & 2498883
11B. PRIMARY AIR
The ash pit door is to be used to introduce initial combustion air when the stove is started from cold or re-fuelled with its body temperature below 150°C on the top plate.
The ash pit door must be drawn out to the manufactured stop to allow draft until the top plate has reached 150°C and then closed. (see 11C.)
Ash pit drawer / Primary air control 11C. SECONDARY AIR (AIRWASH)
After the stoves top plate has reached 150°C the ash pit should be closed whereby the preset (fixed) Secondary air (air wash) control will continue combustion (this must not be adjusted as pre-set to 4mm).
The air wash control in conjunction with the tertiary control will produce clean combustion and clear the majority of blackening on the door glass apart from a band at the top or fly ash deposits on the inner face of the glass (when the stove reaches 175°C or above).
It is important to note that the stoves performance is directly relative to the flue chimneys draft. The stronger the draft the faster the stove will heat from cold and respond to the air controls. Excessive draft will cool the stove faster when combustion is finished.

12. FIRING THE STOVE Do not over fire the stove for its initial firing within its first twenty four hours run period to ensure damage does not occur within the castings. On initial firing and when or if the stove has been unfired for a period in a cold or damp room or airspace, the bottom cleaning plugs may leak water (condensates). This will soon clear when the stove flue ways and body begin to warm up.
a) Initial Firing model 850 and 678 (slow heat release for 15250 operation)
The stove may be started with a firelighter or paper twists and kindling.
Start with 1.5kg kindling with the glass door left ajar 5mm or so (no more).
Model 850 – The stove should be fired with 3 loads of 3kg (batches) of wood for total 10kg. MODEL 678
Once Kindling has begun thorough combustion (about 5 minutes) load with 4 small split logs approx 150 mm diameter x 320mm long sacked in wigwam fashion (about 2kg).
Pull primary air flow out to manufacturers stop and run until re-loading required and then load remainder of 10kg wood load (2 batches)
The primary air flow should be reduced to 10mm until stove has reached 150°C design temperature and then closed. Use in same fashion for 2-3 minutes after each refuelling.

Patent pending USA, Canada, Europe & Russia | UK Patent nos: 2467433 & 2498883
b) Subsequent Firing Models 850 and 678.
Re-starting the stove after its initial firing should be carried out with the ash pit cleared out and pulled out for a quarter of its distance up to the stop/retainer within the ash pit.
A raging lively fire will be seen which is ideal. Run at this rate for the first load of fuel.
Ash pit drawer / Primary air control
c) Re-fuelling after starting Models 850 and 678
Re-load with 2 further batches of 3kg of dry split logs at each re-fuelling.
Once the fuel has almost burned away re-fuel with a full firebox pulling the primary control out a quarter (to manufacturers stop) for 2-3 minutes.
Smoke may escape from the top of the doors until the stove has reached 150°C and when re-fueling.
Run for a few minutes if the stove has reached 150°C to ensure combustion of the new fuel has begun.
d) Over Firing warning Models 850 and 678 Do not over fill the fire box, 3 kg or so of split logs is a typical full load. Running the stove above 200°C constitutes over firing the stove and after which point damage may occur to the stove. Under firing warning Do not run the stove under 150°C on “tick over” as this can result in tar or creosote build-up in the flue and within the stove.

13. CONTINUOUS BURNING (Standard stove operation for 13240 designation) Models 850 and 678
a) Initial Firing
The stove may be started with a firelighter or paper twists and kindling.
The stove should be loaded with 4 split logs about 150mm diameter x 320mm long stocked in wigwam fashion in the fire box.
The primary air control should be pulled out to the manufacturers set stop. Run until re-loading is needed, where upon add the remainder of the first 10 kg batch of wood (2-3 batches).
Do not over fire the stove for its initial firing within its first twenty four hours run period to ensure damage does not occur within the castings.
The stove may be run night and day continuously but will not continue to burn longer than 1.5 -2.5 hours before re-fuelling (dependent upon how well the flue draws and density or condition of the fuel that is being burned).
b) Subsequent Firing
Re-starting the stove after its initial firing should be carried out with the ash pit cleared out and pulled out for a quarter of its distance up to the stop/retainer within the ash pit. A raging lively fire will be seen which is ideal. Run at this rate for the first load of fuel.
c) Re-fuelling after starting
Refuelling must only be carried out with sufficient fuel within the stove to immediately ignite the new fuel load. Overloading could cause excessive smoke.
If the fire bed is too low for immediate ignition of the new fuel load suitable kindling must be used to restart the fire.
Re-fuel before the initial load of fuel is fully burned away with maximum 150mm diameter split dry logs stacked with the end grain pointing away from the door.
Run for a short period with the ash pit door pulled out to the manufacturers stop to establish a bright fire then close. The stove may be run on this basis for as long as needed.
Your Ecco stove will not stay in overnight. It will need re-lighting the next morning.

14. EXTRA CONTROLS Models 850 and 678 Excessive draft over .006 inches of water gauge may be moderated by installing a draft diverter into the flue pipe off the top of the stove and duly balanced. Speak to your retailer for advice or fitting. 15. ASH REMOVAL Models 850 and 678
Ash removal must only be carried out when the stove is not alight as by removing the ash draw would over fire the appliance.
To remove ash collected in the ash draw, simply pull out the ash draw to its quarter extended position; pull up safety catch leaver on the side of the ash draw upon which the ash draw may be fully extracted for cleaning.
Always re-fit the ash draw after emptying fully following the lighting/firing procedure at 21c in this instruction manual
16. FUELS 16a Wood
Wood as a fuel must be maximum 20% moisture content and split logs are nominally 400mm maximum in length and 10 - 15 cms in diameter or below for best combustion, (measured at any one point over the width of the split log) see 25h) for explanation.
Harder, more dense logs or wood will generally burn more slowly. Timber should ideally be loaded in wigwam fashion or flat across the width of the stoves fire box to ensure the end grain does not release volatiles towards the glass door and hence blacken it quickly.
Under no circumstances must the Ecco Stove be used as an incinerator to burn household or industrial waste of any description – only untreated 20% humidity wood must be used.
Liquid fuels must not be burned on this appliance. 17. RE-FUELLING (for smoke control areas) Models 850 and 678
When the Ecco Stove has been on a minimum or 2-3 hours burning, re-fuelling should either be carried out with two or three split logs at each time, to ensure proper and complete combustion, and produce minimum smoke. (Fuel loaded to be maximum 150mm diameter x 320mm maximum length).
12 | P a g e
E850 E678 Instructions | current as of May 2015 | Version 3
Patent pending USA, Canada, Europe & Russia | UK Patent nos: 2467433 & 2498883
Ideally re-fuel on a bright fire. If the fire has burned down to sparse embers the stove may be re-fuelled with two or three logs or a full fire box upon which the ash pit draw should be drawn out quarter way (to the safety stop) and the stove fired for 5 – 10 minutes to create initial combustion, then closed to allow clean air controls (tertiary and air wash) to take over. (Follow initial lighting procedures).
Smoke may escape the door if re-fuelling is carried out on a bright or lively fire if the stove body is below 150°C. Open the door to the fire box slowly when re-fuelling to minimise smoke spillage into the room as the door will create a vacuum drawing the smoke out of the fire box unless the flue ways are above 150°C. UNDER NO CIRCUMSTNCES MUST THE STOVE BE OPERATED WITH THE DOOR OPEN APART FOR REFUELLING OTHERWISE EXCESSIVE SMOKE WILL BE PRODUCED.
18. TAR DEPOSITS Tar deposits will not form in the stove or on its flue ways if adequately seasoned logs (below 25% moisture content are used) and the stove generally burned above 150°C with a bright fire. If tar deposits form in either the fire box or the flue way, the fuel being burned is not adequately seasoned and damage will occur within the stove along with poor performance. 19. FLUE CONNECTION AND FLUE LININGS Models 850 and 678
The flue outlet on the stoves top is 150mm+ and accepts a 150mm stove pipe which must be bedded into the outlet with fire cement for a gas tight seal. (Minimum 1mm thick metal pipe)
The nominal flue outlet of the Ecco Stove is 150mm diameter for which a 150mm flue liner insulated around within the masonry chimney with perlite grains or similar or rockwool wrap is strongly advised, or a suitably insulated pre-fabricated twin wall stainless steel flue system.
Any joints must be self tap screwed and jointed with fire cement.
Flue’s up to 9m in height are adequate in 150mm inner diameter.
Flues over 9m in height should be 175mm in the diameter.
High temperature hot face inner linings or coatings are suitable materials but ideally with a maximum flue area of 225 x 225mm.
Pumice hot face linings with insulation or leka pellets are suitable.
13 | P a g e
E850 E678 Instructions | current as of May 2015 | Version 3
Patent pending USA, Canada, Europe & Russia | UK Patent nos: 2467433 & 2498883
Under no circumstances should the Ecco Stove be connected directly to clay linings within chimneys, unless those clay liners have a hot face lining fitted within, in order to reduce condensation within the chimney flue. 20. CLEANING AND MAINTENANCE Models 850 and 678
Flue ways within the Ecco Stove should be cleaned two monthly in continuous combustion for which the stove should be let out (not burning).
Cleaning access points are located on the stoves top surface (4 hot plates) which must be lifted vertically to access the vertical flue ways (2 each side).
After brushing down (and up) the deposits can be scraped or vacuumed out by removing the cleaning plugs located on the front of the bottom section (2 discs).
The first section of flue pipe vertically off the appliances top flue outlet MUST include a flue cleaning access.
Clean down through this into the stoves top; brush along the top flue chamber beneath the flue outlet and vacuum out that chamber by sliding a flexible vac hose to left and right.
Seasonal Use. During a period when the stove will not be fired for example, during the summer period, leave the ash pit door open, 2mm, to minimise condensation build up within the stove. Clean the flue ways as described in the previous paragraphs (20. Cleaning and Maintenance) and clean out both the ashtray and fire box. You may oil the outer paint surface with a light mist of releasing oil, similar to WD40 and leave for the next heating season.
Check the rear back baffle boards and replace if cracked or broken.
Check all seals are fixed firmly in place on the door; ash pit front and cleaning plugs.
Remove and or clean above the steel gull wing baffle plate in the top of the firebox.
Ensure the chimney flue and stove pipe are swept early summer time or after stoves shut down for the summer.
Oil the door hinges and door catch mechanism all in readiness for the new heating season. a) Adverse flue conditions (downdraught or pressurisation) will result in poor performance; door
glass blackening and sooting in the flue ways. Such conditions must be rectified by improving flue performance immediately. Clean any tar/deposits off the door glass.
b) Repairs or replacements must be carried out by a competent engineer.
Flueways are accessed by removing the cleaning plugs at a+ b + c + d and brushing vertically with the flue brush provided.

E850 E678 Instructions | current as of May 2015 | Version 3
Patent pending USA, Canada, Europe & Russia | UK Patent nos: 2467433 & 2498883
After cleaning vertically and horizontally the cleaning plugs at the front of base should be removed and cleaned out with a vacuum cleaner or suction hose.
Lastly remove the gull wing baffle at top of fire chamber and shake off – slide the whole assembly toward the rear of the stove and then left or right to drop down. Re-instate in reverse order.
Always check the flue is clear after a prolonged period of shutdown or non use.
Plugs must always be re-fitted firmly in place before lighting or whilst running the Ecco Stove.
The firebox door and ash pit door should remain closed at all times other than re-fuelling (See lighting and refuelling instructions)
The Grate should be de-ashed by raking through the fire box door to ensure combustion air can flow through the grate bars (only carry out these works when the stove is not alight).
The door glass may be cleaned of either grey transparent fly ash deposits or tar deposits from its inner surface with a proprietary glass cleaner available from your retailer.
The stove is now ready for re-use after all cleaning plugs have been re-fitted. 21. PAINT FINISHES Paint finishes on your Ecco Stove may produce a heavy chemical smell for a number of initial firings from being newly painted. You may colour co-ordinate your Ecco Stove by painting its outer surfaces with non oil based or non-flammable paints. (Certain paints may discolour however). 22. ASSEMBLY Model 850 The Ecco Stove is delivered in 9 main structural parts being bottom section* grate section; left sides; right sides; back section; lower front top section; lower back top section and upper top section* .

24. DUCTED WARM AIR (MODEL 678)
By fitting the hot box with one extra trim between it and the stoves top, up to four 100mm diameter rigid pipes can be fitted off the stoves top to other rooms. These pipes simply push into the openings in the top of the hot box.
Grilles with spigots are available separately along with rigid 100 mm pipes and 100mm alloy flexible tubing (none of which are included as standard). Maximum duct length per output is 1.5 metres. Each duct must rise constantly to its point of emission into the adjacent room (or the same room the Ecco Stove stands in) with a minimum angle of 45⁰ for natural convection.
The rigid pipes are used as decorative outlets rather than flexible tubing visible directly off the top of the hot box. A steel locating plate which clamps onto the flue pipe is available to hold the rigid duct pipes in position for appearances only.
25. GENERAL a) Safe Operation. The outside surface of the Ecco Stove will reach temperatures above 200°C on
full firing and must not be touched as burning will occur. Care must be taken. In the event of overheating – above 210°C ensure the fire door and ash pit door are fully closed in order to cool the rate of combustion and slowly cool the stove. a i) Any combustible materials must be a minimum of 600mm away from the appliance. Plaster board or plaster will crack if within 300 mm of the appliance. Non combustible materials must be minimum of 125mm from sides; 125 mm above (150mm for E850) and 50mm from rear.
b) No modifications must be made to Ecco Stove or structural work carried out upon it unless by authorised personnel (aesthetic changes may be made by the manufacturer without notice).
c) Replacement parts must only be of the manufacturers supply and design. The following parts are packed with the Ecco Stove. 1 x Bottom section (silicon carbide), Ashcan; 2 x alloy cleaning pugs; 1 fixed alloy disc Model 850 only 1 x alloy t shaped joint seal – listed in order of assembly from the base up including seals affixed (complete perimeter of stove). 1 x grate section (silicon carbide) 1 x cast iron fixed grate 2 x side sections (silicon carbide) 2 x vermiculite dividers Model 850 only 1 x back section (silicon carbide) 2 x vermiculite back baffles with predrilled holes; 1 x vermiculite spacer block. – 2 for Model 678 1 x alloy t shaped joint seal (part perimeter of stove with door and frames width omitted)

d) In the event of a chimney fire the fire box door and ash pit must be tightly closed and the local fire brigade alerted immediately.
e) The Ecco Stove when used as a slow heat release appliance may be left for a 10 hour period after its final firing to release heat slowly on a falling heat. Should it be required this method of heating be continued a fresh fuelling may be undertaken and initial firing procedures followed and the method then repeated with two fills of fuel (or more) before the appliance is left to release its heat slowly.
f) Continuous burning: The Ecco stove may be run as a continuous heat producing appliance and after which may then be allowed to burn out and continue in its role as a slow heat release appliance until its next re-fuelling period – see 25e above.
g) Parts and materials required for installation: Sack truck, lifting frame; rubber mallet; chimney connecting pipe.
