GAS-FIRED BOILER Boiler Manual
PART 1: PRODUCT AND SAFETY INFORMATION
(CONT’D)
Before Installing
WHEN SERVICING BOILER
• To avoid electric shock, disconnect electrical
supply before performing maintenance.
• To avoid severe burns, allow boiler to cool
before performing maintenance.
BOILER OPERATION
• Do not block flow of combustion or
ventilation air to boiler.
• Should overheating occur or gas supply fail to
shut off, do not turn off or disconnect electrical
supply to circulator. Instead, shut off the gas
supply at a location external to the appliance.
• Do not use this boiler if any part has been
under water. Immediately call a qualified
service technician to inspect the boiler and to
replace any part of the control system and
any gas control that has been under water.
BOILER WATER
• If you have an old system with cast iron
radiators, thoroughly flush the system (without
boiler connected) to remove sediment. The
high-efficiency heat exchanger can be damaged
by build-up or corrosion due to sediment.
• Do not use petroleum-based cleaning or sealing
compounds in boiler system. Gaskets and seals
in the system may be damaged. This can result
in substantial property damage.
• Do not use “homemade cures” or “boiler patent
medicines.” Substantial property damage,
damage to boiler, and/or serious personal injury
may result.
• Continual fresh make-up water will reduce boiler
life. Mineral buildup in heat exchanger reduces
heat transfer, overheats the stainless steel heat
exchanger, and causes failure. Addition of
oxygen carried in by make-up water can cause
internal corrosion in system components. Leaks
in boiler or piping must be repaired at once to
prevent make-up water.

WARNING
WHAT TO DO IF YOU SMELL GAS
• Do not try to light any appliance.
• Do not touch any electric switch; do not use
any phone in your building.
• Immediately call your gas supplier from a
neighbor's phone. Follow the gas suppliers'
instructions.
• If you cannot reach your gas supplier, call the
fire department.
CAUTION
Consider piping and installation when
determining boiler location. Any claims for
damage or shortage in shipment must be filed
immediately against the transportation
company by the consignee.
CAUTION
NEVER use automotive or standard glycol
antifreeze, even ethylene glycol made for
hydronic systems. Use only inhibited propylene
glycol solutions, which are specifically
formulated for hydronic systems. Ethylene
glycol is toxic and can attack gaskets and seals
used in hydronic systems.
