Improper installation, adjustment,

 

alteration, service or maintenance can

 

cause property damage, personal injury

 

(exposure to hazardous materials) or loss

 

of life. Installation and service must be

 

performed by a qualified installer, service

 

agency or the gas supplier (who must

 

read and follow the supplied instruction

 

before installing, servicing, or removing

 

this boiler. This boiler contains materials

 

that have been identified as carcinogenic,

 

or possibly carcinogenic, to humans).

Boiler service and maintenance –

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

the boiler. This boiler is equipped with a control which

will automatically shut down the boiler should air or

vent be blocked. If vent or air blockage is easily

accessible and removable, remove it. The boiler should

attempt to restart. If blockage is not obvious or cannot

be removed, have the boiler and system checked by a

qualified service technician.

• Should overheating occur or gas supply fail to shut off,

do not turn off or disconnect electrical supply to the

circulator. Instead, shut off the gas supply at a location

NOTICE

￿WARNING

When calling or writing about the boiler

Please have the boiler model and serial number from the boiler rating plate.

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.

Factory warranty (shipped with unit) does not apply to units improperly installed or improperly operated.

Failure to adhere to the guidelines on this page can result in severe personal injury, death, or substantial property damage.

external to the appliance.

• Do not use this boiler if any part has been under water.

The possible damage to a flooded appliance can be

extensive and present numerous safety hazards. Any

appliance that has been under water must be replaced.

Boiler water –

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 the 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”. Serious damage to the boiler, personnel, and/or property may result.

Continual fresh make-up water will reduce boiler life. Mineral buildup in the heat exchanger reduces heat transfer, overheats the stainless steel heat exchanger, and causes failure. Addition of oxygen carried in by makeup water can cause internal corrosion. Leaks in boiler or piping must be repaired at once to prevent makeup water.

Freeze protection fluids –

NEVER use automotive antifreeze. 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.
