STEP 4

Apply a bead of silicone to the inner and outer flue collars of the fireplace and using appropriate length of pipe section(s) attach to fireplace with three (3) screws. Follow with the installation of the inner and outer elbow, again secure joints as described in “Connecting Vent Pipes”.

STEP 5

Measure the horizontal length requirement including a 2” (51 mm) overlap, i.e. from the elbow to the outside wall face plus 2” (51 mm) (or the distance required if installing a second 90° elbow. (Fig. 26)

Always install horizontal venting on a level plane.

STEP 6

Use appropriate length of pipe sections - telescopic or fixed and install. The section which goes through the wall is packaged with the starter kit, and can be cut to suit if necessary.

Sealing vent pipe and firestop gaps with high tem- perature sealant will restrict cold air being drawn in around fireplace.

STEP 7

Apply high temperature sealant to 4” (100mm) and 7” (175mm) collars or the termination one inch away from crimped end. Guide the vent terminations 4” and 7” col- lars into their respective vent pipes. Double check that the vent pipes overlap the collars by 2” (50mm). Secure the termination to the wall with screws provided and caulk around the wall plate to weatherproof.

Support the horizontal pipes every 36” (914mm) with metal pipe straps.

Check the fireplace to make sure that it is levelled and properly positioned.
