STEP 6
Note: If using the charcoal wall plate, Part #52202-CG,
and collar, Part #52203-CG, put them in place before
putting the pipe sections through the wall.
Use appropriate length of pipe sections - telescopic or fixed
- and install. The sections which go through the wall are
packaged with the starter kit, and can be cut to suit if
necessary. (Fig. 20).

Sealing vent pipe and firestop gaps with
high temperature sealant will restrict cold
air being drawn in around fireplace.
Support horizontal pipes every 3 feet (91
cm) with metal pipe straps.
Check fireplace to make sure it is levelled
and properly positioned.
STEP 7
Apply high temperature sealant to 4" and 7" collars or the
termination one inch away from crimped end. Guide the
vent terminations 4" and 7" collars into their respective vent
pipes. Double check that the vent pipes overlap the collars
by 2". Secure the termination to the wall with screws
provided and caulk around the wall plate to weatherproof.

STEP 5
Measure the horizontal length requirement including a 2"
overlap , i.e. from the elbow to the outside wall face plus 2"
(or the distance required if installing a second 90) elbow.
(Fig. 19).

Always install horizontal venting on a
level plane.
BELOW GRADE INSTALLATIONS
When it is not possible to meet the required vent terminal
clearances of 12 inches (305mm) above grade level a
starter vent kit is recommended. It allows installation depth
of down to 7 inches (178mm) below grade level. The 7
inches is measured from the centre of the horizontal vent
pipe as it penetrates through the wall.
If venting system is installed below ground,
we recommend a window well with adequate
and proper drainage.
