POTENTIAL CAUSES FOR FLAME SENSOR NOT TO PROVE
Venting Related Issues (See each manual for specific information relating to tested and approved venting
systems)
● Partial Intake Liner - exhaust and intake liner must be of approved size and run continuous to termination
● Unapproved Termination
● Unapproved Vent Configuration
● Enclosed Termination
● Incorrect Vent Restrictor Setting
● Crossed Liners
● RTV Sealant on Venting (Do not use RTV sealant on units)
● If Liners have large sags pull liners tight and keep run as straight as possible
Gas Supply Issues (See each units manuals for required pressure)
● Ensure Sediment Trap (Drip Leg) is installed in supply line prior to the gas valve. SIT requirement for iron pipe.
● Measure Inlet Gas Pressure with unit off. Make note and then measure gas pressure with the unit turned on (call for
heat)
● Measure Outlet Gas Pressure with unit on(call for heat)
● If inlet working pressure is to low check for blockage or incorrect gas line size
● If outlet working pressure is incorrect and inlet pressure is correct check the following:
● Valve Modulator - If an electronic modulator was added see diagram 27-28 to troubleshoot the modulator
● Converted Units - ensure factory diaphragm and spring have been removed
● Cold Vents/ Cold Start - unit may need to be cycled again to overcome the cold vent/cold start. Turn unit off then back
on to cycle the unit again
● Misplaced logs/glass or stone - check manual for correct certified media placement
