Turn the main burner switch
to ON
Wait 10 seconds
Is there a spark at
the pilot hood?
NO
YES
Did the pilot
light?
NO
YES
Pilot is lit but
Igniter
continues to
spark
YES
1. Ensure the DFC module is not locked out by turning the unit
off then back on again. If there is a spark it was locked out.
2. Is there a spark at the base of the igniter? If so the porcelain
is cracked. Replace the electrode.
3. Check that the batteries are installed correctly. If so check
the battery voltage at the white plastic connector (CN1). Place
one lead at the #1 red wire and one to the #3 black. Set multimeter to DC volts. If 4.40 volts or less replace batteries. If a
remote control is used check the #2 & #3 wires.
4. Confirm the ground wire is properly connected to the CN2
on the DFC module. (Yellow wire)
5. Is a spark seen at the CN3 electrode connection at the
DFC module and ground wire? Confirm connector is firmly seated
6. Disconnect the elctrode from CN3. Attach a jumper wire to
CN3. Place other end of jumper 1/8" away from the valve/ground
and turn unit on. If there is a spark replace electrode.
If no spark replace the DFC module.
1. Check for approximately 3 volts at the green wire
attached to the on/off switch. One lead to green
one lead to white. If no replace the DFC module.
2. Check the continuity at the Continuos Pilot Switch,
(CPI). If continuity is found switch is good, if no replace.
3. Check the blue wire on the CPI for approximately3
volts. If there is no voltage replace the DFC module.
4. Confirm the igniter wire is connected to the DFC
module at CN3. Also check continuity of the igniter.
Replace if necessary.
5. Check continuity at the EV1 pilot coil to ground. If no
continuity replace the valve.
6. Confirm the orange wire is connected to the EV1
pilot coil.
7. Check the voltage at EV1 pilot coil to ground. When
switched on there should be 5 volts DC for 2 seconds,
then it drops to .5 volts DC. If there is no voltage replace
the DFC module.
8. Check the incoming gas pressure
1. Adjust the pilot to ensure it is engulfing the flame sensor.
2. Confirm the flame sensor wire is connected to the DFC
module and the DFC module is grounded.
3. Ensure flame sensor and pilot hood are clean
4. Confirm the flame sensor has continuity. If no continuity
replace the flame sensor. If found continuity replace the
DFC module.
NO
Does the
Burner come on?
YES
Unit is working properly
NO

1. Check the main burner coil EV2 to ensure the
green wire is connected.
2. Check connection of ground wire at the valve
and the DFC module.
3. Check the voltage to the EV2 main burner coil to
ground. When switched on you should read 5 volts DC for
2 seconds. It will drop to .5 volts DC after the initial
2 seconds. If no voltage replace the DFC module.
4. Check the continuity of the EV2 main burner coil.
If there is continuity the valve is good, if not replace
the valve.
5. Check the outgoing gas pressure.

YES
Does the flame
modulate
High to Low?
NO
1. Flame modulation is not an available option.
2. Check to see if modulator is installed. If not install one
3. Is the Smart stat on? If yes, turn off Smart Stat so
flame can be manually modulated.
4. Check modulator for continuity. Disconnect the black plug
from wiring harness. On the back side of plug place on lead
orange wire, one on yellow wire. Reading should be
approximately 26 ohms. Also check continuity between the
black and brown wires. It should also be approximately
26 ohms.
NO
1. A fan is not an available option.
2. Is there power to the Fan Control Module (FCM)?
3. Is the fan plugged into the FCM in the outlet marked fan?
4. Is the wiring harness from the receiver connected to the
FCM marked COM? The connector is keyed.
5. Is the FCM turned on?
6. Ensure the remote control is set for the fan to come on
7. There is a fan snap disk that must be hot enough to
activate the fan. Is unit hot enough?
8. Check the fan snap disc. It is normally open so when hot
there should be contnuity.
9. Ensure power is getting to the fans. If not check the FCM
fan outlet for 120 volts. If there is no power out check the
fuse in the FCM.
10. Check the fan rheostat.
11. Check for continuity on the fan. If no continuity replace
the fan.

Unit is working properly
1. Check to ensure the receiver switch is set to the
remote position.
2. Check to ensure the remote transmitter is turned on.
If not press the ON/OFF key.
3. Check batteries in receiver and remote transmitter.
Remote transmitter has a low battery indicator.
4. Ensure remote transmitter and receiver are
synchronized.
5. Is thermostat on? If yes, raise the temperature set
point higher than the room temperature.
6. Is the Smart Stat on? If yes, raise the temperature set
point higher than the room temperature.
