Installation / Operation Instruction Manual

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.
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.
