temperature. If this light does not come on in the first nine minutes of start-up, the stove will shut 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.

NOTE: Do not open the control box. This will void the warranty. Do not plug in or remove control box without first unplugging the stove.

9.THERMOCOUPLE

a.The thermocouple is located on top of the firepot 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 fire 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” (25mm) into the firepot.

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

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 fire 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.

b.To replace this blower, remove the lower rear 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.

15.FEED SYSTEM

a.The feed system is located on the right side of the stove and can be removed as an entire assembly 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
