SPRING CLEANING:
When the heating season is over make sure that you clean out all of the fuel in the hopper, firebox area,
ash pan and firepot area. Corn can accumulate moisture over the summer months causing the unit to rust
and the fuel to mold.
It is recommended that prior to shutting down the unit in the spring, run the unit on the higher settings for
a day to help clean out the heat exchanger system, venting system and firebox area.
When the unit is cleaned out, take the venting apart, clean out the fly-ash, rinse the venting out with a
water hose and let dry, take the draft blower off and clean, clean out all areas such as back heat exchanger
and lubricate the auger, auger tube, firepot area, fuel stirrer shaft and bearings and hopper area with a light
oil. (Something like Pam cooking oil works great to coat the inside of the unit and the moving parts.
Clean the glass, doors and outer cabinet so that you are ready for the next heating season.
Power Outage
During a power outage, the furnace will shut down safely. It will not automatically restart when the
power returns, unless the exhaust is still up to temperature (see “Lighting Instructions”).
Overheating
A high temperature fan limit switch will automatically shut down the furnace if it overheats. The
furnace will need to be manually re-lit. Allow 45 minutes before re-lighting.
The circuit board is equipped with a 5 amp. Fast acting fuse. If the unit does not operate and there is
power coming into the unit, check and replace the fuse. Always replace with a fast acting fuse.
The Magnum furnace has a fan limit and high limit controls located inside of the unit on the left side.
IMPORTANT:
Make sure that the power source conforms to the requirements of the furnace. It is
highly recommended that you run a separate circuit to assure constant power. A 15 amp circuit is needed.
Disconnect the power source before performing any maintenance or electrical service work.
Plug the power supply cord into a surge protected and grounded 15-amp branch circuit. The outlet must
be checked for correct polarity. Check the outlet for a minimum 115 volts and that the branch circuit is
not overloaded with too many appliances hooked to it. Run a separate circuit if it is overloaded.
