The information contained in this manual is intended for use by qualified professional installers, service technicians or gas suppliers. Consult your local expert for proper installation or service procedures.

IMPORTANT

Consult and follow local Building and Fire Regulations and other Safety Codes that apply to this installation. Consult your local gas utility company to authorize and inspect all gas and flue connections.

IMPORTANT

Your conventionally vented gas appliance must have a supply of fresh air circulating around it during burner operation for proper gas combustion and proper venting.

￿WARNING

Should overheating occur or the gas supply fail to shut off, do not turn off or disconnect the electrical supply to the pump. Instead, shut off the gas supply at a location external to the appliance.

To minimize the possibility of serious personal injury, fire or damage to your unit, never violate the following safety rules.

1.Boilers and water heaters are heat producing appliances. To avoid damage or injury, do not store materials against the appliance or the vent- air intake system. Use proper care to avoid unnecessary contact (especially children) with the appliance and vent-air intake components.

2.Never cover your appliance, lean anything against it, store trash or debris near it, stand on it or in any way block the flow of fresh air to your appliance.

3.UNDER NO CIRCUMSTANCES must flammable materials such as gasoline or paint thinner be used or stored in the vicinity of this appliance, vent-air intake system or any location from which fumes could reach the appliance or vent-air intake system.
