(Fig. 28) Use the appropriate length of pipe section – telescopic or fixed
–and install. The 20" section of pipe which goes through the wall is packaged with the 7DVSK kit, and can be cut to suit if necessary.

(Fig. 29) Apply high temperature sealant to 4" and 7" collars 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 7
Support the horizontal pipes every three (3) feet (92 cm) with metal pipe straps. Make sure that the horizontal vent pipe is installed on a level horizontal plane.
STEP 8
Recheck the fireplace to make sure that it is levelled, properly positioned, and nailed or screwed to the floor.
If applied, the fireplaces adjustable frame drywall strips (nailing flanges) should be fastened. See "Framing & Finishing" section, page 6.
