In really cold conditions, ice buildupmay occur on the terminal and should be removed asrequired.- Refer to “VENTING” section to ensure correct location ofstorm collars.- Check pressure readings:Inlet pressure can be checked by turning screw (A)counter-clockwise 2 or 3 turns and then placingpressure gauge tubing over the test point. Gauge shouldread 7” (minimum 4.5”) water column for natural gas or13” (minimum 11”) water column for propane. Checkthat main burner is operating on ‘HI’.Outlet pressure can be checked the same as aboveusing screw (B). Gauge should read 3.5” water columnfor natural gas or 10” water column for propane.Check that main burner is operating on ‘HI’.AFTER TAKING PRESSURE READINGS, BE SURETO TURN SCREWS CLOCKWISE FIRMLY TORESEAL. DO NOT OVER TORQUE.Leak test with a soap and water solution.- Ensure air shutter opening is free of lint or otherobstructions.- Check that the logs are correctly positioned.- Open air shutter to increase the primary air.- Check the input rate: check the manifold pressure andorifice size as specified by the rating plate values.- Check that the door gasketing is not broken or missingand that the seal is tight.- Check that both vent liners are free of holes and wellsealed at all joints.- Check that minimum rise per foot has been adhered tofor any horizontal venting.- Clean the glass with a recommended gas fireplaceglass cleaner. DO NOT CLEAN GLASS WHEN HOT.- If deposits are not cleaned off regularly, the glass maybecome permanently marked.- Ensure exhaust bracket gasket seal.- Check door seal.- Check for exhaust blockage.- Check that venting is installed correctly.- Room is in negative pressure; increase fresh air supply.AB42.2! WARNINGAlways light the pilot whether for the first time or if the gas supply has ran out, with the glass dooropen or removed.
