Hearth and Home Technologies 800 owner manual Unit BURNING, no Call Light

8.THERMOSTAT WILL NOT START UNIT

A.Check the power to the stove.

1.Unplug for 10 seconds and then plug in. The exhaust blower should come on. If it does, go to B.

B.The thermostat or the thermostat wiring maybe faulty.

1.Disconnect the thermostat wires from the terminal block located on the back of the stove. Make a jumper wire in order to create a manual bypass to determine if the stove or the thermostat is faulty.

NOTE: Unplug the stove while hooking up the jumper wire. Plug the stove back in and the unit should come back on and light. If the unit lights, check the thermostat and the wires connecting them.

C.Snap disc #2 would bypass the thermostat if an overheat situation occurs. The snap disc should reset itself once it cools down.

D.Snap disc #3 may need to be manually reset if the unit has overheated.

E.Check the control box (consult dealer).

9.UNIT FAILS TO SHUT OFF

A.Check the thermostat and the thermostat wires.

1.Remove one of the thermostat wires from the terminal block; the stove should go into a normal shutdown cycle.

B.Check the control box (consult dealer).

C.Check the junction box (consult dealer).

10.SMOKE FROM THE CONVECTION AIR OUTLET

A. Check the exhaust blower housing and all venting connections.

B.Most problems with smoke-in-the-house are the result of a poor venting system.

11.CONVECTION BLOWER KEEPS RUNNING OR FAILS TO START

A. Snap disc #1 may need to be replaced.

B.Check the wire connections on snap disc #1 and the convection fan to be sure a good contact is being made.

C.Check the convection blower and capacitor (consult dealer).

12.STOVE CYCLES ON AND OFF, THERMOSTAT ALWAYS ON

A.Check that snap disc #1 is coming on and turning the convection blower on. If not, snap disc #2 could be bypassing the thermostat until the snap disc cools and resets itself.

13.LARGE FIRE, ASH BUILDUP AND DIRTY GLASS

A.Clean the firepot. Check the firepot gasket for a good seal between the firepot and firebox surfaces.

B.Visually check the cleanliness of the firebox, the heat exchangers and venting system.

C.Reduce the feed rate, if necessary, to maintain a fire height of about 4" to 6" (102mm to 153mm) above the top of the firepot.

D.If all the above do not help, an air adjustment may be needed. The air adjustment plate is located in the ash cleanout in the pedestal. Open more to increase air to help even the air to fuel ratio.

14.UNIT BURNING, NO CALL LIGHT

A.Replace light bulb (#85 lamp).

15.STOVE IGNITES THEN GOES OUT, LIGHTS STILL ON = NUISANCE SHUTDOWN

A.Inspect the thermocouple and the cover.

1.Make sure that the thermocouple end and the cover make contact.

2.The thermocouple and the cover should extend approximately 1” (25mm) into the firepot.

3.Push the reset button. When the thermocouple reaches 200°F (93°C) the GREEN LIGHT will come on, and at 1000° F (538°C) the RED LIGHT will come on.

B.Check the fire height. It should be 4” to 6" (102mm to 153mm) out of the firepot.

1.Too high of a fire will lower vacuum in the firebox and the vacuum switch may turn off the feed system, resulting in total shutdown or feed system shutdown until vacuum is regained.

NOTE: This may also happen in complicated venting systems, or at high altitudes. Use the feed adjustment plate to slow fuel input and reduce flame height. If this does not help, check the air adjustment plate.

2.Too low of a fire will let the firepot temperature drop below 1000°F (538°C) and will turn the stove off. Increase fuel, check for sawdust and bridging of pellets.

C.Check the heat exchanger and the venting system for buildup or restriction (cleanout ash buildup).

D.Check the vacuum switch for proper operation.

1.Make sure that the vacuum hose is not clogged.

2.With normal operation, the vacuum switch should shut the feed system off when the door is opened, and restart the feed system when the door is closed again.
