Display is Flashing “E2”
Possible Causes Possible Remedies: (Unplug stove fi rst when possible)
1. Airfl ow switch hose or stove attachment pipes for hose
are blocked.
Unhook air hose from the air switch and blow through it.
If air fl ows freely, the hose and tube are fi ne. If air will not
fl ow throw the hose, use a wire coat hanger to clear the
blockage.
2. The air inlet, burnpot, interior combustion air cham-
bers, combustion blower, or exhaust pipe are blocked
with ash or foreign material.
Follow all cleaning procedures in the maintenance sec-
tion of the owner’s manual.
3. The fi rebox is not properly sealed.
Make sure the door is closed and that the gasket is in
good shape.
4. Vent pipe is incorrectly installed.
Check to make sure vent pipe installation meets criteria
in owner’s manual.
5. The airfl ow switch wire connections are bad.
Check the connectors that attach the gray wires to the
air switch.
6. Combustion blower failure.
With the stove on, check to see if the combustion blower
is running. If it is not, you will need to check for power
going to the combustion blower. It should be a full cur-
rent. If there is power, the blower is bad. If there is not,
see #7.
7. Control board not sending power to combustion
blower.
If there is no current going to the combustion blower,
check all wire connections. If all wires are properly con-
nected, you have a bad control board.
8. Control board not sending power to air switch.
There should be a 5-volt current (approximately) go-
ing to the air switch after the stove has been on for 30
seconds.
9. Air switch has failed.
To test the air switch, you will need to disconnect the air
hose from the body of the stove. With the other end still
attached to the air switch, very gently suck on the loose
end of the hose (you may want to remove the hose en-
tirely off the stove and the air switch fi rst and make sure
it is clear). If you hear a click, the air switch is working.
BE CAREFUL TOO MUCH VACUUM CAN DAMAGE
THE AIR SWITCH.
