Trouble Shooting - Harman Stove Company 44 Magnum Owner's Manual

Fig. 29
Reasons the Feeder Might Not Feed
1. No coal in the hopper.
2. The unit has not reached 165 degrees Fahrenheit.
The feed motor will not run until the ESP senses
165 degrees Fahrenheit on start up; therefore, if
your starting fire did not get hot enough the feed
motor will not start.
3. A foreign object may be in the hopper preventing
the flow of coal.
4. The feed motor has failed.
5. The control board has failed.
Reasons for Sulfur Smell or Carbon Monoxide
Detector Sounding
1. Chimney draft is too low. Check chimney and
chimney connecter.
2. One or both of the doors are open.
3. Flue pipe might be blocked with flyash.
Reasons the Fire Has Gone Out
1. No fuel in hopper.
2. The feed rate is too low.
3. A foreign object in the hopper is preventing the flow
of coal.
Cleaning Glass While Stove Is Operating
1. Turn the unit to LOW at setting #1 and allow the
unit to cool down.
2. Turn the unit to OFF. This will slow the combustion
blower to it's lowest speed. Now the viewing door
can be opened with minimal exhaust leakage.
3. Use a safety razor in a handle to scrape the inside
of the glass with the blade almost flat to the surface.
See Figure 29. The window can now be cleaned
with a liquid cleaner and a non-synthetic cloth.
CAUTION: HOT GLASS MAY CAUSE THE
CLEANER TO BOIL.
4. Close the door and turn the unit back to the desired
setting.

TROUBLE SHOOTING

4. The feed motor has failed.

7. The feed rate knob is turned down so low that it is
actually in the "OFF" position.
8. A fuse has blown.

Low Heat Output
1. The coal too wet.

counterclockwise.
