The pipe cover protects
the plumbing pipes to
the water heater. It is
fixed to the bottom of
the water heater, so it
hides the plumbing and
improves the appearance
of the installation.
3. Recess box:
It allows for “clean” installations. The water heater fits inside
the recess box, which hides and protects the whole water heater and plumbing.
The recess box will fit between most wall studs.

It prevents the backflow of air through the exhaust vent. This
helps prevent harmful exhaust gases from entering the home, as
well as helping to prevent the unit from freezing in areas where
cold air can be blown or drawn into the exhaust system.
Install this adaptor in accordance with the installation instructions
that are packaged with the adaptor and any applicable codes.
9007996005 (4” Backflow preventer and F-F adaptor):
Must be installed in the vertical position.
9008146005 (4" Universal Appliance Adaptor, F-F adaptor, backflow preventer, condensate drain trap): Must be installed in the
vertical position on the heater's flue collar.
4. Sidewall vent terminator (Hood) and Wall thimble:
Sidewall vent termination (Round) and Wall thimble:
This component is used to terminate direct-vent (sealed
combustion) systems with indoor models that require a
3 in. intake and a 4 in. exhaust. This concentric termination provides the convenience
of only having to make one penetration through a sidewall instead of two separate
penetrations for the intake and exhaust piping. The termination includes a bird
screen, restricting small animals, pests, and foreign objects from entering into the
vent system. This sidewall termination is available in two different sizes to cover a
wide range of wall thicknesses. For different wall thicknesses,there are two ranges
of lengths available. (Refer to the venting manufacturer's specifications for details.)
