When installing a side wall vent system
with the minimum equivalent vent
length (87º elbow and vent termination
shortened to 19”/483 mm) from boiler
back to the outside wall, a wall
thickness of at least 6”/152 mm is
required.
For walls with a thickness less than
6”/152 mm, means must be provided
to offset the boiler from the wall
(see fig. 9).

3. Attach wall flashing
to inside of
wall using the screws and plugs
provided.
4. Attach wall flashing
to outside of
