DELUXE HORIZONTAL VENTING KIT
The Deluxe Horizontal Venting kit was an optional through-
the-wall-only concentric flue system for use only on U.S.
residential and light duty commercial Power Direct Vent gas
water heaters. This section gives directions for replacing
series 300 and 310 PDV water heaters terminated with
the Deluxe Horizontal Venting Kit.
1. Carefully disconnect the existing venting from the
original water heater. Take care not to damage the
venting as it will be reconnected to the new water
heater.
2. Thoroughly inspect the vent termination for any
damage (see Figure 28).
3. Check that all seams and joints in the vent termination
air box are airtight.
4. Check that there are no leaks or cracks in the
termination airbox.
Important:
If there is any damage to the airbox, the water
heater venting must not be connected to the Deluxe Vent
termination.
It might be necessary to trim the vent to suit the height
of the new water heater. For the purpose of these
installations, the calculations for “equivalent length” will
refer to the distance from the blower assembly on the
water heater to the inside of the wall at the Deluxe Vent
Termination.

Connections To The Air Box
1. Slide an O-ring over each of the fittings on the air box.
Note:
An appropriate sized O-ring can be ordered from
the heater manufacturer. Request kit number 100269737.
2. Slide the exhaust vent piping over the exhaust fitting
on the air box. Ensure the O-ring remains in place
between the piping and the fitting.
3. Slide the air intake vent piping over the air intake fitting
on the air box. Ensure the O-ring remains in place
between the piping and the fitting.
4. Drill 7/64” pilot holes for a #8 screw (see Figure 28).
Take care not to damage the O-ring.
5. Secure the vent piping to the air box with screws (see
Figure 28).
