WARNING!
This section provides necessary, but only general, information and requirements regarding flue
venting and combustion air piping installation for this system. The installer must refer to
Section 6 of the AM Series User Manual, GF-146, for very important information and
instructions regarding the installation of the venting and combustion air piping, or risk creating
a dangerous situation.

4.1 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 Section 6 of the AM Series User Manual, GF-146.

4.2 Prevention of Combustion Air Contamination

Install air inlet piping for the appliance as described in Section 6 of the AM Series User Manual,
GF-146. 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.
