down. The stove will not try to relight again by
itself. You must manually push the reset button
to reset the cycle.
d. If you suspect a problem with the control box,
disconnect the power supply from the stove, then
remove the control box and take it to your nearest
Quadra-Fire dealer for testing.

will void the warranty. Do not plug in or
remove control box without rst unplugging
the stove.
9. THERMOCOUPLE
a. The thermocouple is located on top of the repot
inside the ceramic protection tube. Remove the
ceramic tube and inspect the thermocouple for
deterioration or breakage.
b. Check the transition from thermocouple to wire to
see if they are tight and making a good electrical
connection (located on the right side of the re box
behind the right side panel).
c. Upon reinstalling the ceramic cover, be sure the
thermocouple is touching the inside end of the
ceramic tube and that the cover is extending 1”

for ten minutes, then turn off. After the stove
cools, the snap disc will automatically reset itself
and the stove will relight.
12. SNAP DISC #3 (BACKBURN PROTECTOR) 250°F
a. Snap disc #3 is mounted on the back of the auger
tube in the center of the stove. To access it, open
the right side panel. If, for any reason, the re
tries to burn back into the feed system or push
exhaust up the feed tube, this snap disc will shut
the entire system off. However, sometimes in
shipment the disc will trip and shut power off to
the entire stove. Power failures and surges can
also trip this disc. To reset, unplug the stove from
outlet and push in the red reset button in the
center of the snap disc, then plug the stove back
in and try to relight it.
13. BLOWER #1 (EXHAUST BLOWER)
a. The 70 cfm exhaust blower is located on the right
side of the stove. The exhaust blower is designed
to pull the exhaust from the stove and push it out
through the venting system. To inspect it, open
the right side panel (facing the stove from the
front). The motor may now be visually inspected.
To inspect the impeller refer to the heat exchanger
maintenance cleaning section.
14. BLOWER #2 (CONVECTION BLOWER)
a. The 160 cfm convection blower is mounted at the
rear of the stove. There are two impellers, one
on each side of the motor. The convection blower
blows heated air through the heat exchange
system into the room.

screen then unplug the molex connector, lift on
the rear of the motor slightly, just enough so the
grommets on the rear will clear the two studs.
Pull straight out.

which includes the feed motor, its mounting
bracket bearing, and feed spring (auger). To do
this, remove two Phillips head screws located next
to the nylon bearing and the whole feed system
will pull straight out. This system uses a hollow
d. The thermocouple sends a millivolt signal to the
control box to obtain the green and red lights for
the preset temperatures.
10. SNAP DISC #1 (CONVECTION BLOWER) 125°F
a. Snap disc #1 is located on the right side of the
stove, on the bottom of the heat exchanger box.
Two purple wires are connected to it. This snap
disc turns the convection blower (heated air) on
and off as needed. Power is always present at
snap disc #1.
11. SNAP DISC #2 (THERMOSTAT OVERRIDE)
200°F
a. Snap disc #2 is also located on the right side of
the stove, below snap disc #1. Two yellow wires
are connected to it. This snap disc will bypass the
thermostat and turn off the stove if an overheat
condition occurs, or if the convection blower
should fail to operate. The stove will go into a
normal shutdown: the combustion blower will run
