In Canada: Vent system termination is NOT permitted in screenedporches. Vent system termination is permitted in porch areaswith two or more sides open. You must follow all side walls,overhang and ground clearances as stated in the instructions.
Heat & Glo assumes no responsibility for the improper perfor-mance of the fireplace when the venting system does not meetthese requirements.
For Vertical Terminations - To locate the vent andinstall the vent sections:
• Locate and mark the vent centerpoint on theunderside of the roof, and drive a nail through thecenterpoint.
• Make the outline of the roof hole around thecenterpoint nail.
• The size of the roof hole framing dimensionsdepend on the pitch of the roof. There MUST BEa 1-inch (25.4 mm) clearance from the verticalvent pipe to combustible materials.
• Mark the roof hole accordingly.
• Cover the opening of the installed vent pipes.
• Cut and frame the roof hole.
• Use framing lumber the same size as the roofrafters and install the frame securely. Flashing an-chored to the frame must withstand heavy winds.
• Continue to install concentric vent sections upthrough the roof hole (for inside vent installations)or up past the roof line until you reach the appro-priate distance above the roof (for outside termi-nations).

• Save the remaining ember materials for use duringfireplace servicing.
• Place lava rock on burner tray.
• Replace the glass door and a front trim door on theunit.
Before lighting the fireplace, be sure to do thefollowing:• Remove all paperwork from underneath the
fireplace.Review safety warnings and cautions• Read the Safety and Warning Information section
at the beginning of this Installers Guide.Double-check for gas leaks• Before lighting the fireplace, double-check the unit for
possible gas leaks.Double-check vent terminations.• Before lighting the fireplace, double-check the unit for
possible obstructions that could be blocking the ventterminations.
Double-check for faulty components• Any component that is found to be faulty MUST BE
replaced with an approved component. Tampering withthe fireplace components is DANGEROUS and voidsall warranties.
A small amount of air will be in the gas supply lines. Whenfirst lighting the fireplace, it will take a few minutes for thelines to purge themselves of this air. Once the purging iscomplete, the fireplace will light and will operate normally.
Subsequent lightings of the fireplace will not require thispurging of air from the gas supply lines, unless the gasvalve has been turned to the OFF position, in whichcase the air would have to be purged.
NOTE: The fireplace should be run 3 to 4 hours on theinitial start-up. Turn it off and let it cool completely.Remove and clean the glass. Replace the glass and runthe fireplace for an additional 8 hours. This will help tocure the products used in the paint and logs.
