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
