Burner
lights when
pilot only
should light
Yes
Pilot
holds
flame?
No
1. Verify transmitter is not powered on or in thermostat mode calling
for heat. Display should say OFF next to thermometer image on
display for thermo off.
2. Verify receiver switch is not in ON position
3. Ensure all electrical connections are secure based on the wiring
diagram
4. Verify proper voltage at the main valve connection ( EV2 green).
See page 15.
- If voltage is present replace IFC board
- If voltage is not present replace gas valve (solenoid not
closing)
1. Check that the continuous pilot switch is ON (down position)
2. Verify pilot flame makes full contact with flame sensor
- Verify gas pressure on full capacity
- Verify turbulence is not pushing flame off flame sensor
3. Clean the flame sensor and inspect wiring for damage
4. Verify pilot assembly is properly grounded and pilot hood is
brushed clean of debris and securely pressed down.
5. Replace flame sensor
6. Check voltage at pilot valve connection (EV1 orange) See page 15
- If no voltage present when calling for pilot, replace IFC
board
- If voltage is present, replace gas valve (valve not
opening)
Main
burner
ignites?
No
1. Verify the receiver switch is in ON position
- If in the REMOTE position verify remote is powered ON
and thermostat is OFF.
2. Verify electrical connections are properly connected according to
the wiring diagram and replace any damaged harnesses
3. Verify the pilot flame is properly directed to ignite the burner
4. Verify piezo is not sparking if so, go back to Piezo Still Sparking
5. Verify proper components are installed for type of gas used
6. Check continuity of the main burner coil. See pg 16
7. Check for voltage at the main burner connection (EV2 green) See
page 16
- If voltage is present replace gas valve (not opening)
- If no voltage is present replace IFC board
No
Yes
Main burn-
er remains
on
No
1. Verify the receiver switch is in ON position
- If in REMOTE, verify remote ON and thermostat says OFF
2. Verify electrical components are properly connected according to
the wiring diagram and replace any damaged harnesses
3. Verify pilot flame makes contact with flame sensor. Clean flame
sensor of any debris or silicone film.
4. Verify gas pressure on full capacity is according to manual
5. Check for voltage at the main burner connection (EV2 green) See
page 16
- If voltage is present when drops out, replace gas valve
- If no voltage, replace IFC board
Yes
