STOP!! — Read before proceeding

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

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.

•You must maintain the boiler as outlined in this manual and have the boiler started up and serviced at least annually by a qualified service technician to ensure boiler/system reliability.

Boiler operation —

•Do not block flow of combustion or ventilation air to 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.

•Do not allow contaminated air to enter the boiler air inlet pipe. See page 4 for details.

•Should overheating occur or gas supply fail to shut off, do not turn off or disconnect electrical supply to boiler. 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, which has been under water.

Boiler water —

•Have boiler water chemistry checked at least annually by a qualified service technician.

•DO NOT use petroleum-basedcleaning 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". Serious damage to boiler, personnel and/or property may result.

•Continual fresh makeup water will reduce boiler life. Mineral build- up in boiler heat exchanger reduces heat transfer, overheats the metal, and causes heat exchanger failure. Addition of oxygen can cause internal corrosion in system components. Leaks in boiler or piping must be repaired at once to prevent makeup water.

•Do not add cold water to hot boiler. Thermal shock can cause boiler heat exchanger to crack.
