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” section.

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. 27)
