provided in accordance with information in this manual under “Locating the

Water Heater” and “Minimum Clearances”, and with National Fuel Gas Code

and local codes.

or pipe breakage.

This water heater must be properly vented and connected to an

approved vent system in good condition. DO NOT operate water heater

with the absence of an approved vent system. A clean and

unobstructed vent system is necessary to allow noxious fumes that

could cause injury or loss of life to vent safely and will contribute toward

maintaining the water heater’s efficiency. The acceptance of the venting

system is dependent upon full compliance with these installation

instructions. When an existing Category I appliance is removed or

replaced, the original venting system may no longer be sized to properly

vent the attached appliances.

Venting system must not pass through rated fire separations.

The venting system must be free to expand and contract. This venting

system must be supported in accordance with these instructions.

NOTICE

For installations in Canada, field supplied vent piping must comply with

CAN/CGA B149.1 (latest edition) and be certified to the Standard For Type BH,

Class II, 65°C, Gas Venting Systems, ULC S636. Components of this listed

system shall not be interchanged with other vent systems or unlisted

pipe/fittings. All components and specified primers and cements of the certified

vent system must be from a single system manufacturer and not intermixed with

other system manufacturer’s vent system parts. The supplied vent connector

and vent termination are certified under ULC S636 and are also certified as part

of the water heater. Refer to the following tables for approved venting materials,

primers, and cements. All approved primers and cements are to be used within

their marked time limitations.
