There are some common items to check on the SHA and associated equipment. These include the
following:
Proper operation of SHA Fuel Control Valve
Condition of Fuel Supply and Overflow Hoses and associated quick disconnect connectors
Condition of Stack Assembly and Cap
Accumulation of ash (if solid fuel used) in heater chamber
LUBRICATION SERVICE INTERVALS
The door hinge and latch assembly should be lubricated with a light machine oil or WD-40 when stored.
All metal heater components should be wiped down with a rag dampened with a light machine oil or WD-
40 before storage or after cleaning to prevent rust.
CLEANING
Proper cleaning of the SHA and components is an integral part of maintenance. It will help prevent
possible problems in the future, so make it a habit to clean the SHA and its components whenever
necessary.
The heater frame interior can be cleaned with a rag; the exterior can be cleaned with a brush. Wipe down
all hoses with a rag. Make sure that all connectors are free of debris and that they work freely.
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 severe injury or death.
After operating the heater in solid fuel mode, be sure to clean the inside of the stack assembly sections
with a rag or brush to remove any creosote buildup that may occur.
