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
•
Only transport the unit using the right transportation equipment, such as a hand truck with a
fastening belt or special equipment for maneuvering steps.
•
During transportation, the unit must be secured on the transportation equipment to prevent it
from falling off.
•
Protect all parts against impacts during transport.
•
Observe the transportation markings on the packaging.
•
Leave the protective covers on the connections until ready to install.
•
During transportation, cover the flue gas and air intake connections at the top of the unit with
plastic or other material to avoid contamination.
3.10 Unpacking and Transporting
