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 the 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. 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.

•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 in system components. Leaks in boiler or piping must be repaired at once to prevent makeup water.

￿ CAUTION 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.

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 near by phone. Follow the gas supplier’s instructions.

•If you cannot reach your gas supplier, call the fire department.

•Installation and service must be performed by a qualified installer, service agency, or the gas supplier.

Do not use “homemade cures” or “boiler ￿ CAUTION patent medicines”. Serious damage to

the boiler, personnel, and/or property may result.

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.
