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.
