• Chimney: Remove cap from chimney. Inspect chimney. Ensure chimney is not blocked (check for animal or
bird
nests).
• Loading Door: Oil door hinges and latch. Inspect gaskets. Verify that door seals tightly (apply thin coat of lipstick
to loading fl ange, shut door, reopen and inspect marking on the gasket).
• Plumbing: Open all isolation valves.
• Pump: The circulator shipped with the appliance is water-lubricated. No oiling is required. Check other circulators
in the system. Oil any circulators requiring oil, following circulator manufacturer’s instructions.
Over-oiling will damage the circulator.
Use only S.A.E. 20 motor oil to lubricate the motor. Do not use universal household
oils. Motor could be damaged, resulting in possible severe property damage.
• Pressure: Verify cold pressure is approximately 5 psi. Fill if necessary.
• Water Chemistry: Verify heating system water pH of 8.5 to 11.0. Adjust as necessary. Add corrosion inhibitor
package to raise pH. Add scale inhibitor as testing indicates .
• Corrosion Inhibitor: Verify level per manufacturer’s instructions.
• Power: Turn on power supply at the appropriate circuit breaker. Ensure that the pump is running.
• Aquastat: Inspect and test the aquastat. Verify operation by turning aquastat temperature below the
appliance temperature. The boiler should cycle off . Return aquastat to original setting.
• Air Vents: Inspect automatic air vents . The cap must be unscrewed one turn to allow air to escape. If the air vent
is leaking, remove cap and briefl y push valve and then release to clean the valve seat. Replace cap by twisting all
the way onto valve and then unscrewing one turn.
• Start-up: Review start-up Procedures.
• Safety: Review all safety Precautions.
• Housekeeping: Verify that area is free of any combustible materials , gasoline and other fl ammable vapors
and liquids or rags.
Do not use petroleum-based cleaning or sealing compounds in the heating system. Severe dam
age to the heating system will occur, resulting in substantial property damage.
Eliminate all system leaks. Continual fresh makeup water will reduce appliance life. Minerals can
build up in the appliance, reducing heat transfer, overheating the metal. Leaking water may also
cause severe property damage.
Electrical shock hazard: Turn off power to the appliance before any service operation on the
appliance except as noted otherwise in this instruction manual. Failure to turn off electrical power
could result in electrical shock, causing severe personal injury or death.
