A wind shield over the termination of the outside air pipe or a 90-degree elbow or bend away from the prevailing winds
MUST be used when an outside air pipe is installed through the side of a building. The outside air termination MUST
be at least 1ft (0.305m) away from the exhaust system termination.
The outside air pipe on your heater is 2" (50.8mm) OD. The outside air connecting pipe must be at least 2" (50.8mm) ID.
The outside air connection used MUST NOT restrict the amount of air available to your heater. The outside air connecting
