WARNING

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.

For installations in Canada, the 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.
