Alternative separate kit (Exhaust outside & intake inside)
Figure 9.6 (Twin Pipe Φ 3.25 in)
This configuration of the twin pipe kit allows discharging the exhaust gasses outside. The air supply
is obtained with an air intake pipe. This allows taking air from the room where the boiler is installed.
If either an additional 45° or 90° accessory elbow is used then the maximum permissible length of
either pipe must be reduced by 3.0 ft or 5.4 ft respectively.
Note: When utilizing this option, see page 14 for room ventilation details.
Installation:
•
Drill hole C (on the wall template) through the outside wall that is less than 18” thick.
•
Cut the pipe as necessary so that no more than 6” protrudes from the house.
•
Slide the exhaust pipe through the hole.
•
Slide one rubber wall trim piece on the pipe from inside and one from outside.
•
Attach each collar to the boiler with the gasket and screws provided.
•
Insert each elbow into its corresponding collar.
