3.7 Vent and Combustion Air Piping

This boiler requires a special vent system, designed for pressurized venting.
The boiler is to be configured for either direct vent installation or for installation using room
combustion air. When room combustion air is considered, see Chapter 6.
Vent and air may be vented vertically through the roof or out a side wall, unless otherwise
specified. You may use any of the vent/air piping methods covered in Chapter 6.
Be sure to locate the unit such that the vent and air piping can be routed through the building
and properly terminated.
The vent/air piping lengths, routing and termination method must all comply with the methods
and limits given in Chapter 6.

3.8 Prevention of Combustion Air Contamination

Install air inlet piping for the appliance as described in Chapter 6. Do not terminate vent/air in
locations that can allow contamination of combustion air.
WARNING!
Ensure that the combustion air will not contain any contaminants. Contaminated combustion
air will damage the unit, resulting in possible personal injury, death or substantial property
damage.

3.9 Transporting the Unit
