Appliance Set-Up
A. Outside Air Attachment
Parts and Supplies Needed: 1 piece of metal flexible pipe,
3" X needed length. 1 Rodent Screen, Plus, you'll want to
obtain a trim ring for finishing around the pipe on the inside
wall.
1. Remove the knockout from the bottom shield. There are
three small areas that are not previously cut. You can cut
these tabs using a hacksaw or by drilling them. A small
rounded file will be helpful in removing any sharp burrs
from the cut.
2. Determine an appropriate hole location, through the wall.
Be sure there are no studs or other supporting members.
Also ensure there are no electrical wires or plumbing
contained within the wall.
3. Make the hole through the exterior wall using a hole
saw or reciprocating saw. You'll want the hole to be just
slightly larger than the metal flex pipe.
4. Attach the rodent screen to one end of the flex pipe,
and insert it through the wall until the back of the screen
cover is against the outside surface.
5. Hold the flex pipe in place to make an accurate
determination of the length needed. Cut the flex pipe to
length.
6. Slide the trim ring onto the flex for the inside wall portion.
7. Slide the other end of the metal intake flex pipe through
the bottom shield and secure it to the shield with a
minimum of two screws. The flex pipe does not make a
positive connection to the appliance, it will supply outside
air as a proximity source.
8. Secure the trim ring in place for finishing the inside wall
area.
9. Seal around the rodent screen on the exterior wall, using
silicone caulking.
CAUTION
Never draw outside combustion air from:
• Wall, floor or ceiling cavity.
• Enclosed space such as an attic or garage
