This is the most common type of installation style.
Set the unit in place.
Install a minimum 24” (61 cm) vertical chimney.
Install a 90° elbow, and mark the exterior wall where the vent would
pass through.
Cut a 10” (25.4 cm) minimum hole in the wall to maintain clearances
to combustibles around vent pipe. Frame hole if as shown in Figure 24.
Install wall thimble.
Install interior finished collar
Install the vent section through the wall and then install the vent
termination.
Seal around the termination using a non hardening mastic.
CORNER INSTALLATION:
This type of installation can be used in a corner installation. If a 90°
elbow is used in the horizontal plane, 36” (91.4 cm) must be subtracted
from the allowable horizontal run shown in Figure 22.
Place the unit in place.
Drop a plumb bob from the ceiling to the center point of the
flue outlet.
Cut a 10” (25.4 cm) hole in the ceiling and the roof. Refer to
Figure 28.
Install the ceiling support and insulation guard.
Install the roof flashing. Ensure that the roof flashing is installed
under the roofing material so that a watertight seal is created.
Install the flue pipe from the top of the unit through the roof.
Ensure that all flue pipe and unit maintain required clearances
to combustibles.
CORNER INSTALLATION:
