GAS-FIRED HEATER Installation Manual

PART 1: PRODUCT AND SAFETY INFORMATION

(CONT’D)

Before Installing

WHEN SERVICING THE MUNCHKIN CONTENDER

• To avoid electric shock, disconnect electrical

supply before performing maintenance.

• To avoid severe burns, allow heater to cool

before performing maintenance.

MUNCHKIN CONTENDER OPERATION

• Do not block flow of combustion or

ventilation air to heater.

• 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 heater if any part has been

under water. Immediately call a qualified

service technician to inspect the heater and

to replace any part of the control system and

any gas control that has been under water.

HEATER WATER

• If you have an old system with cast iron

radiators, thoroughly flush the system (without

heater 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 the

heater 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 heater or piping must be

repaired at once to prevent make-up water.

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'

glycol solutions, which are specifically

formulated for hydronic systems. Ethylene

glycol is toxic and can attack gaskets and seals

used in hydronic systems.
