Service and maintenance
Label all wires prior to disconnection when servic-
ing controls. Wiring errors can cause improper and
dangerous operation.
To avoid personal injury, death or property damage,
keep boiler area clear and free from combustible
materials, gasoline and other flammable vapors
and liquids.
Do not block flow of air to boiler. Incomplete
combustion and flue gas spillage can occur.
Do not store sources of hydrocarbons (i.e., bleaches,
cleaners, chemicals, sprays, paint removers, fabric
softeners, etc.) in boiler area. This can contribute
to shortened boiler/vent system life.
