General Maintenance Instructions
General maintenance should be performed before each use and at least annually by a qualified
service agency.

vapors and liquids.
NOTE: Periodic cleaning to be performed, as necessary.
Outside Casing Washdown
1. Disconnect electrical supply and turn OFF the gas supply to the heater.
2. Close and secure all access panel.
3. Spray the heater down with water only. DO NOT use cleaning solution.
4. Allow at least one (1) hour for the heater to completely dry before reconnecting the power cord to
the electrical supply.
Internal Components Cleaning
1. Check blower wheel for accumulation of dust on the concave side of the blades. Blades may be
cleaned using bottle brush and compressed air. Check to ensure the flow of ventilation and
combustion air is not restricted.
2. Check the burner and orifice. These parts should be kept clean and free from dust and carbon
build-up. DO NOT touch the hot surface ignitor. Handling the ignitor could cause damage or
premature failure. Remove the burner casting and clean out internally, using compressed air to
remove dust and debris that may have accumulated during the off season (i.e. spider webs, wasp
nests, feathers, etc.). Inspect the burner orifice for blockage. If necessary remove and clean
reinstall burner.
3. Check the air proving switch for accumulation of dust or debris. Clean with a dry brush or cloth.
Safety Inspection
1. Inspect the heater for damage that could render the heater inoperable.
2. Inspect the mounting hardware to ensure that it is properly secured.
3. Inspect the power cord and hose assembly for cuts, abrasions or excessive wear. If the power cord
or hose assembly is cut, it must be replaced prior to putting the heater in service.
