STOP!! — Read before proceeding

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

Air contamination

•To prevent potential of severe personal injury or death, check for products or areas listed in table at right before installing boiler. If any of these contaminants are found:

• remove contaminants permanently. — OR —

•isolate boiler and provide outside combustion air. See national, provincial or

local codes for further information. — OR —

•for CGs boilers only — combustion air may be ducted from outside to the boiler air intake.

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 the 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 within an hour. 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 pump. 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.

•Have the building monitored when it is vacant for an extended period. Safety controls can shut down the boiler at any time. The loss of heat can result in significant damage due to freezing.

Boiler water

•DO NOT use petroleum-basedcleaning or sealing compounds in boiler system. Water seal deterioration will occur, causing leakage between sections and damage to heating system components. 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 buildup in sections reduces heat transfer, overheats cast iron, and causes section failure. Addition of oxygen and other gases can cause internal corrosion. 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 sections to crack.
