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).
Fig. 19
Always install horizontal venting on a level plane.
STEP 6
Note: If using the charcoal wall plate, Part
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.

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.

Support horizontal pipes every 3 feet (91 cm) with metal pipe straps.
Check fireplace to make sure it is levelled and properly positioned.
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.
