11.0 troubleshooting27.4symptom problem test solutionFlames are consistently toolarge or too small.Carboning occurs.Appliance is over-fi red orunderfired.- Check pressure readings:Inlet pressure can be checked by turning screw (A) counter-clockwise2 or 3 turns and then placing pressure gauge tubing over the testpoint. Gauge should read as described on the chart below. Check thatmain burner is operating on ‘HI’. Outlet pressure can be checked thesame as above using screw (B). Gauge should read as described onthe chart below. Check that main burner is operating on ‘HI’. AFTERTAKING PRESSURE READINGS, BE SURE TO TURN SCREWSCLOCKWISE FIRMLY TO RESEAL. DO NOT OVER TORQUE.Leak test with a soap and water solution.Air shutter improperly adjusted. - Return air shutter to specifi ed opening, see “venturi adjustment” section.Carbon is being depositedon glass, logs, rocks,media or combustionchamber.Air shutter has become blocked. - Ensure air shutter opening is free of lint or other obstructions.Flame is impinging on theglass, logs, rocks, media orcombustion chamber.- Check that the logs are correctly positioned.- Check for ceiling or oscillating fans that may be influencing the flame.- Open air shutter to increase the primary air. See “venturi adjustment”section.- Check the input rate: check the manifold pressure and orifi ce size asspecifi ed by the rating plate.Exhaust fumes smelled inroom, headaches.Not enough combustion air. - Increase fresh air supply. (Use one of the methods described in ANSIZ223.1 / NFPA 54 or the applicable local code.)Not enough ventilation air. - Increase fresh air supply.

See “venturi adjustment”section.- Check the input rate: check the manifold pressure and orifi ce size asspecifi ed by the rating plate values.Main burner will not light;or is slow to light, noisypilot.Inlet pressure too high. - Adjust inlet pressure to ensure 7.0” W.C. (17.4mb) at gas valve fornatural gas and 13.0” W.C. (32.4mb) for propane.Pilot fl ame blowing off, missingthermopile.Pilot is not functioningproperly.Pilot has been painted - Using a piece of sandpaper or emery cloth remove the paint from thepilot hood, ignitor and flame sensor.Pilot goes out whilestanding; Main burner is in‘OFF’ position.Gas piping is undersized. - Turn on all gas appliances and see if pilot flame flutters, diminishes orextinguishes, especially when main burner ignites. Monitor appliancesupply working pressure.- Check if supply piping size is to code.- Correct all undersized piping.Pilot fl ame is not large enough. - ODS Burner requires checking.INSERTPHOTOOF VALVEHEREPressure Natural Gas(inches)Natural Gas(millibars)Propane(inches)Propane(millibars)Inlet * 7”(MIN. 4.5”)17.4mb(MIN. 11.2mb)13”(MIN. 11”)32.4mb(MIN. 27.4mb)Outlet 3.5” 8.7mb 10” 24.9mb* Maximum inletpressure not toexceed 13”• Always light the pilot whether for the first time or if the gas supply has run out with the glass door open or removed.• Turn off the appliance completely and let cool before servicing.
