STEP 2

Slide venting component on collar of fireplace. Secure component to fireplace by running a screw (self-tap- ping) through tab & into outer casing. (Fig. 26)

STEP 3

Measure the horizontal length requirement including a 2” (51 mm) overlap, i.e. from the elbow to the outside wall finish plus 2”, or the distance required if installing a second 90° elbow. (Fig. 27)

STEP 5

Guide the vent termination’s 4” and 7” collars into their respective vent pipes. Double check that the vent pipes overlap the collars by 2” (51 mm). Secure the termination to the wall with screws provided and caulk around the wall plate to weatherproof. (Fig. 29)

STEP 6

Support the horizontal pipes every 36” (914 mm) with metal pipe straps. Make sure that the horizontal vent pipe is installed on a level horizontal plane.

STEP 4

Use appropriate length of pipe section - telescopic or fixed - and install the horizontal vent sections. A starter section of pipe which goes through the wall is packaged with the 7TCRVT kit, and can be cut to suit if necessary. (Fig. 28)
