WARNING
Risk of carbon monoxide poisoning or fire due to joint separation 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.
