Side wall vent termination installation

1. Provide side wall opening (see table above) to install
vent termination.
2. Slide vent termination 1 with wall flashing 3 into
opening (drain openings must be located on the
outside of the wall, pointing downward).
3. Attach wall flashing 2 to inside of wall using the
screws and plugs provided.
4. Attach wall flashing 3 to outside of wall.
IMPORTANT
If required the vent termination may be shortened.
IMPORTANT
Potential gaps between the vent-air intake and the
surrounding construction which may cause air, rain or flue
gases to leak into the wall or the building, must be sealed
with approved outdoor sealant/caulking to prevent leakage
of any kind.
When installing a side wall vent system with the minimum
equivalent vent length (87º elbow and vent termination,
a wall thickness of at least 6 in. (152 mm) is required.
For walls with a thickness less than 6 in. (152 mm), means
must be provided to offset the boiler from the wall (see
illustration above).
