MAINTENANCE:
1. Every construction heater should be inspected before each use, and at
least annually by a qualified service person. Incorrect maintenance my
result in improper operation of the heater and serious injury could
occur.
2. The hose assemblies shall be visually inspected prior to each use of the
heater. If it is evident there is excessive abrasion or wear, or the hose is cut, it
must be replaced prior to the heater being put into operation. The
replacement hose assembly shall be that specified by the manufacturer.
3. The flow of combustion and ventilation air must not be obstructed. Be sure to
check the fan assembly and ensure that the motor and blade are operating
properly.
4. Compressed air should be used to keep components free of dust and dirt
build up. Note: Do not use the compressed air inside any piping or regulator
components.
5. Change fuel filter insert (Part# FVO-418) once per month. Change fuel filter
cartridge (Part# FVO-419) once every 6 months.
6. Change oil nozzle (Part# FV-235B) once per year.
7. Fan Limit Switch (Part# FV-407A) should be replaced if the fan motor does
not shut off after the heat exchanger has cooled down.
8. The High Limit Switch (Part# FV-406) should be checked each season. This
limit switch will ensure the burner shuts down if the temperature exceeds 250º
F at the outlet.
9. Fuel tank should be drained on a regular basis by removing drain plug.
