4.6 Brief description of the automatic firing device

The automatic firing device BIC960 of the UltraGas® only operates in conjunction with the heating control-ler TopTronic®T/UG. For this reason, the automatic firing device only needs to take care of the last re-maining functions to ensure the correct operation of a modulating gas boiler. The automatic firing device comprises the following functions: - PWM fan control (230V AC) - Modulating operation - Common electrode for ignition and flame monitoring (ionisation) - LPG valve and boiler room fan controllable - Inputs for flow sensor 1

flow sensor 2 flue gas sensor water pressure sensor safety temperature limiter (not used) air pressure switch (not used) gas pressure switch - Status outputs “fault” and “flame signal” - Allows connection of additional (external) ignition device - RS 485 connection to TopTronic®T/UG - RS 232 connection to PC - Start attempts: maximum 4 - Safety period: 5 sec - Pre-ignition period: 5 sec - Pre-purging period: 50 sec - Follow-on time pump (230V AC): 5 min after heat demand

Fuses:The BIC 960 is fitted with 3 fuses: 2AT Mains 4AT Pump 4AT Burner fanBlowing of one of the two 4AT fuses securing the pump or the burner fan, respectively, will prevent the affected device from starting. A failure of the mains fuse of the automatic firing device is displayed on the TopTronic®T/UG by the failure message „DATABUS ERROR 70-6“. The failure appears when there is no communication between auto-matic firing device and TopTronic®T/UG .

5. Installation

5.1 Safety information

Caution! Sharp edges pose a cutting hazard. Handle the cladding parts with care and avoid contact with sharp edges.

5.2 Boiler room requirements

The boiler room must satisfy the applicable local building regulations.

The boiler room ventilation must satisfy the applicable local regulations in this regard.

Boilers may not be installed in rooms containing halogen compounds which can be carried into the combustion air (e.g. wash rooms, drying rooms, DIY rooms, hair dresser rooms).

Halogen compounds can originate, for example, from cleaning and degreasing agents, solvents, glue, and bleaching lyes.

Ensure that the required combustion air can flow unhindered at all times.This is important for the correct operation of all the boilers installed therein and to protect the users from an oxygen depleted atmosphere.An adequate fresh air supply meeting the local regulations must be provided.

5.2.1 Room air dependent installationThe applicable regulations do not normally provide any specific data on the size of air intakes. They only require the pressure in the boiler room not to be below 3 N/m2.This means that for a rated thermal output of up to 50 kW an air intake with a cross section of at least 300 cm2 must be available.For rectangular apertures the aspect ratio should not exceed 1.5:1. If a grid is fitted on the air intake, a suitable allowance must be made to obtain an air intake cross section of 300 cm2.

If the combustion air is aspirated from within the boiler room, it is possible to remove the air intake hose (1) to reduce suction noise.

5.2.2 Room sealed installationConfiguration based on a concentric flue system: The suction air is supplied through a double-wall flue system.Ensure the boiler room is sufficiently ventilated.

4 210 266 / 03 15Installation

Configuration using a separating piece (optional):

i • The following must be observed when laying out the intake pipe:

• If the intake opening is installed on the house facade near to a noise-sensitive area (e.g. bedroom windows, garden seating area, etc.) we recommend in-stalling a noise damper in the direct fresh air suction line.

• The intake opening must be easily ac-cessible.

• No chemicals or poisonous substances may be stored close to the intake open-ing

• The intake opening may not be ins-talled beside fume extraction outlets or other venting outlets.

• Ensure that the intake aperture is free from any obstructions at all times (lea-ves, snow, ...)

• A safety grid must be installed on the suction opening on the outside wall.

5.3 Flue gas connection and flue

Due to the low flue gas temperatures, condensate forms within the flue. For this reason, Hoval gas heating boilers can not be connected to convention-al house chimneys.

i The flue gas extraction system must comply with the following directives:• DVGW (TRGI)• ÖVGW• SVGW/VKFPursuant to the abovementioned regula-tions, a flue gas temperature limiter must be installed in the boiler.

The flue gas system must meet the follo-wing requirements:• Gastight• Watertight• Acid-proof• Approved for flue gas temperatures of

up to 120ºC (T 120)• Approved for overpressure

• Unhindered back flow of condensate into the boiler can only be ensured if:

• The gradient of the horizontal connec-tion elements is at least 50 mm/m.

• Only one heat generator may be con-nected to the same chimney.

• If two heat generators are to be con-nected to the same chimney, the rele-vant regulations must be complied with.

• Cross sections and maximum lengths are calculated on the basis of graphs or tables.

• The tables can be obtained from the chimney or flue system manufacturer.

• The calculation values can be obtained from the table under point 4.2.

• The flue gas conduit cross sections and lengths are calculated following the technical data for the boiler.

• The concentric supply air/exhaust sys-tem of the boiler can also be conducted horizontally backwards. The Hoval re-modelling set allows a remodelling on site

5.4 Condensate drainage

i The condensate drainage pipes on the boiler must be made of corrosion resis-tant material. The following materials are suitable for condensate drainage:PVC, PE, PP, ABSThe local regulations regarding conden-sate drainage must be observed.


5.4.1 Design variants

i Before commissioning, the neutralisation box (if fitted) must be filled with neutrali-sation granulate (figure, chapter 6.4).

Before putting into service, the si-phon and the neutralisation box must be filled with water.The water can be filled through the cleaning opening into the neutralisa-tion box and the siphon.

Possibility 1• Stand version with siphon• With neutralisation, condensate discharge into

lower drain line.• Drain optionally on the left or right side.

Heating Water

The European Standard EN 14868 and the directive VDI 2035 must be observed.

In particular, attention must be paid to the following stipu-lations:• Hoval boilers and calorifi ers are designed for heating

plants without signifi cant oxygen intake (plant type I ac-cording to EN 14868).

• Plants with - continuous oxygen intake (e.g. underfloor heating systems without diffusion proof plastic piping) or

- intermittent oxygen intake (e.g. where frequent refill-ing is necessary)

must be equipped with separate circuits.

• Treated fi lling and replacement water must be tested at least 1x yearly. According to the inhibitor manufacturer‘s instructions, more frequent testing may be necessary.

• A refi lling is not necessary if the quality of the heating water in existing installations (e.g. exchange of boiler) conforms to VDI 2035.The Directive VDI 2035 applies equally to the replace-ment water.

• New and if applicable existing installations need to be adequately cleaned and fl ushed befor being fi lled. The boiler may only be fi lled after the heating system has been fl ushed!

• Parts of the boiler / calorifi er which have contact with water are made of ferrous materials and stainless steel.

• On account of the danger of stress cracking corrosion in the stainless steel section of the boiler the chloride, nitrate and sulphate content of the heating water must not exceed 50 mg/l.

• The pH value of the heating water should lie between 8.3 and 9.5 after 6-12 weeks of heating operation.

Filling and replacement water• For a plant using Hoval boilers untreated drinking water

is generally best suited as heating medium, i.e. as fi ll-ing and replacement water. However, as not all drinking water is suitable for use as as fi lling and replacement water the water quality must fulfi l the standard set in VDI 2035. Should the mains water available not be suited for use then it must be desalinated and/ or be treated with inhibitors. The stipulations of EN 14868 must be observed.

• In order to maintain a high level of boiler effi ciency and to avoid overheating of the heating surfaces the values given in the table should not be exceeded (dependent on boiler performance ratings - for multi-boiler plants rating of smallest boiler applies - and on the water con-tent of the plant).

• The total amount of fi lling and replacement water which is used throughout the total service life of the boiler must not exceed three times the water capacity of the plant.
