instructions
III. Main burner will not light
I.
Soot deposits
V.
Flame burns blue and lifts
off burner
VI. Main flame does not burn
properly
VII. Flames impinge on firebox
top
2. Air in gas lines
3. Gas lines may not be connected
4. Low pressure may be caused
by bent line
A. Thermocouple / Valve
1. Weak or improperly located pilot
flame
2. Defective thermocouple
3.Thermocouple
not
properly
4. Open wire connection in pilot
circuit
5. Defective Valve
B. Defective safety circuit
1. Loose or defective connections
A. Valve / Switches
1. Valve control off
2. Blockage at the burner (line,
orifice, or ports)
3. Defective remote
4. Defective wiring or connections
5. Defective Valve
1. Air inlet blocked or restricted
2. Vent system is restricted or
inadequate
3. Logs are sooting up
1. Insufficient combustion air being
supplied
2. Manifold pressure set too high
3. Vent system restricted
1.
Incorrect vent or termination
used.
1. Vent system is restricted or
inadequate
2. Manifold pressure too high
2. Purge gas lines
3. Connect all gas lines
4. Check for a kinked line
1. Adjust and clean pilot. The flame must
impinge on or engulf the thermocouple, as
shown in Figure 27.
2. Replace thermocouple
installed
3. Make sure all wire connections at the gas
valve terminals are tight and the
thermocouple is fully inserted into the
mounting bracket
4. Check wire continuity and connections in
the pilot circuit
5. Check with your voltmeter.
1. Check continuity, tighten wiring or
connections, and repair
1. Turn to "ON" position
2. Check and clean
1. Conduct a continuity test or jumper wire
test and replace if defective, check
batteries
2. Conduct a test with a jumper wire and
repair as required
3. Contact service technician
1.
Clean air inlets
2. Confirm venting & termination are those
which are approved with the appliance
3. Check manual for correct log placement
1. Ensure that no foreign material blocks air
inlets. Ensure the vent is adequate
2. Check manifold pressure
3. Check vent system
1. Confirm venting & termination are those
which are approved with the appliance
1. Correct flue as required
2. Check manifold pressure as required
