SPACE HEATER ARCTIC (SHA)

OPERATION UNDER USUAL CONDITIONS
0005 00-26
WARNING!
Stack Fire
When operating the heater in solid fuel mode, a buildup of creosote can
accumulate on the inside surface of the stack assembly that may result
in a fire inside the stack. To prevent creosote buildup when operating
with solid fuel, the stack assembly should be cleaned daily. Failure to do
so may result in a fire causing severe injury or death.
CAUTION!
Warping of Heater
Heater components may warp from excessive heat caused by an over
fueled fire. Wood and coal can burn extremely hot depending on the
type and size of fuel used. Do not overfuel fire and clean ashes
frequently. If coal is being used as a fuel, add only a small amount of
coal at a time. Coal is very dense and provides high heat output.
Overfilling the heater with coal will cause the heater to run extremely hot
and it will be very difficult to control the heater’s temperature output.
WARNING!
Hot Surfaces
Door and lid assemblies are very hot during operation. Use the cleaning
tool to open the lid or unlatch/open the front door. Handling door or lid
assemblies during operation may result in severe burns.
After preheating the flue as described above, open the front door (1) and position enough crumpled paper
on solid fuel grate (3) to cover it. If using wood as a solid fuel, stack four to five pieces wood
approximately ¼ to ½ inches in diameter (kindling) in a crisscross fashion on top of paper. If using coal as
a solid fuel, place 10-12 pieces of coal that are approximately 2 inches in diameter on top of the paper.
Light the paper with a match. When kindling begins to burn steadily, place 2-3 larger pieces of wood or a
small amount of additional coal on top of kindling. Fuel may be fed either through lid (4) or front door
assembly (1).
Shut/latch door (1). Keep door (1) and lid (4) assemblies shut except when fueling fire or removing
ashes.
Adjust sliding draft gate (5) (open more to increase burn rate and close more to decrease burn rate).
Monitor flame through the sight glass (6) on the lid.
