STEP 4
If the fireplace has crimped ends on the inner and outer flue
collars, apply a bead of high temperature sealant and using
the appropriate venting component(s) attach to the fire-
place with three (3) screws. If the fireplace has no crimps
on the end of the flue collars, the use of high temperature
sealant is not necessary just secure the component with
three (3) screws. Both pipes must be on a level plane. Fig.
42.
STEP 5
Guide the vent termination 4" collar into the 4" pipe then the
7" collar into the 7" pipe. Do not force the venting into
position. If the pipes do not line up with the termination
collars, disassemble elbows or pipes and reattach to the
fireplace collar. (Fig. 42)
STEP 6
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.
Measure from fireplace collar or elbow face to face of
outside wall (add 1-1/2" for vent pipe overlap). Mark pipes
and cut to length. It is very important that the two pipes are
flush with the outside wall once the fireplace is in its final
location.
