7. Remove outside mounting plate with tube attached from wall.
Mark and cut the extra length of the 6-5/8 inch diameter tube
from the opposite end. Do not crimp or enlarge tube.
8. Attach the 4-inch diameter flue outlet tube onto the rigid
venting system or directly to fireplace. Ensure the 4-inch
diameter flue outlet tube is placed as far as possible onto
the rigid venting system. Mark the 4-inch diameter flue outlet
tube 2-1/2 inches beyond the vinyl siding kit or wall. See
Figure 65. Remove the 4-inch diameter flue outlet tube from
rigid venting system. When installing directly to fireplace,
tape gasket needs to be used.
9. Mark or wrap tape completely around the tubes at the
marked points to help in making a true cut. Do not crimp or
enlarge tubes.
10. From outside: Push the 6-5/8 inch diameter inlet tube/
mounting plate onto end of rigid venting system to correct
position. Fasten the outside mounting plate to the vinyl siding
kit or wall with four 10 x 1 1/2" screws. (Ensure upward
slope).
11. From inside: Attach the inlet tube to the collar on the back
of the fireplace (or the rigid venting system) using three self
tapping screws.
12. Seal the 4-inch diameter flue outlet tube. Follow instructions
and diagram (Figure 66).
13. Fasten 4-inch diameter flue outlet tube in place. Do not
"twist" the flue outlet tube into the fireplace collar (or rigid
venting system). Hold the tube by the seam and push in
using a perpendicular "rocking" motion. This ensures the
seam on the tube stay intact.
14. Fasten vent cap end using three 10 x 1/2-inch screws to
mounting plate.
NOTICE: Tape gasket to be applied prior to installing to fireplace
flue outlet tube only. Tape gasket should not be used when
mating the flue outlet tube to a rigid venting system.
