Troubleshooting
Observed Problem Possible Cause Remedy
A. The stove will not turn on. 1. The unit does not have
power.
1. Ensure that the unit is plugged in and that the unit
is not plugged into a switched outlet.
2. The unit is in On/Off ther-
mostat mode and the thermostat
is not calling for heat.
2. Turn the thermostat up to call for heat or switch
the unit to Manual operation mode
3. The fuse has blown. 4. Check the fuse on the circuit board. If it has
blown, replace the fuse. If the fuse blows again see
“The fuse has blown”
B. The stove shuts down unex-
pectedly or does not run and the
#2 error light is ashing.
Control Panel Symptom:
The #2 light will be ashing if
there is insufcient vacuum for
proper operation.
1. Slider damper is closed
down too far to allow for suf-
cient vacuum.
1. Pull the slider damper out to increase the ow of
air through the rebox.
2. Blocked exhaust or venting
system.
2. Check the exhaust system and venting for block-
age. Clean as necessary. See “Routine Cleaning and
Maintenance”
3. Sever negative pressure
in the area where the unit is
installed.
3. Check operation by opening a window on the
same side of the house. Does this solve the problem?
If so, install fresh air to the unit. See “Installation of
Fresh Air.”
The venting system may require a vertical section
to move the vent termination into a lower pressure
zone.
4. Pinch, break, or blockage in
the vacuum hose.
4. Check vacuum hose for pinch points or damage.
Make sure that hose is not blocked up. Replace or
reroute as required.
5. Blocked hose connection in
the exhaust channel.
5. Check hose barb in the exhaust channel for block-
age and clean out if necessary.
6. Damage to vacuum switch
wiring.
6. Inspect the gray wires. If there is any damage,
replace the wiring harness.
7. Combustion fan failure. 7. Visual check- is the combustion fan running? If
not, use a multi meter to ensure the fan is getting
power. If it is, the combustion fan may need to be
replaced. If not, the circuit board may need to be
replaced.
8. Vacuum switch failure. 8. If the above steps fail to solve the problem, the
vacuum switch may need to be replaced.
