3. GENERAL
SPECIFICATIONS
The D-2 Power Vent Assembly is tested and certified to
the latest edition of the American National Standard ANSI
Z21.10.3 for water heaters and Z21.13 for boilers.
The Power Vent Assembly is a fan-assisted combustion
system designed for application to Raypak Heater Models
182 - 400. The unit, when installed as directed, is capable
of operating in applications such as through-the-wall
venting and reduced horizontal and vertical vent pipe
sizes in new and existing installations.
The flue gases are at a temperature that does not promote
condensation and is under higher pressure than the
ambient air; this defines venting category III. Vent material
certified for cat III usage must be used. Please note that
B-vent does not meet this requirement.
The D-2 Power Vent assembly includes a blower with
a 120/240 volt 60 Hz 1.95/1.0A 3200 RPM motor, a
plenum complete with a draft proving switch and a motor
relay. When provided for field mounting the assembly is
equipped with a wire harness.

4. INSTALLATION

The equipment must be installed in accordance with local
codes, or in the absence of local codes with the latest
edition of the National Fuel Gas Code, ANSI Z223.1, the
National Electrical Code, ANSI/NFPA 70.
The equipment shall be installed in accordance with those
installation regulations in force in the local area where
the installation is to be made. These shall be carefully
followed in all cases. Authorities having jurisdiction shall
be consulted before installations are made.
Adding the D-2 power vent to the unit does not change
the service clearance requirements. Consult the manual
for the unit.

Mounting the Assembly

Follow these instructions if the Power Vent venting
system was purchased as an optional assembly kit.
1. Remove existing pagoda top (outdoor units) or
drafthood (indoor units). To remove the pagoda top,
push the four brackets inward and pull up the pagoda
top. The pagoda may then be discarded.
2. Unscrew the four screws holding the outer top using
a Phillips screw driver. Remove the jacket top.
3. Replace the inner stack adapter. If the heater had
a drafthood installed previously, remove the inner
stack adapter and replace it with the Power Vent
stack adapter. Otherwise, install the Power Vent
stack adapter.
4. Unscrew the access panel on the right side of the
appliance. Set aside the screws with the access
panel.
5. Remove the knurled screw holding the front door
and set it aside with the door.
6. Mount the jacket top above the unit. Note: Do not
install at this point.
7. Mount the Power Vent on the outer top.
8. Route the conduit harness of the Power Vent thru
the outer top hole, around the adapter towards the
back of the unit. Continue routing the harness thru
the corner slot, which leads to open area behind the
access panel. Finally, route only the wire harness
thru the 7/8" grommet hole located on the sway
brace. Follow instructions on page 7 to wire the
Power Vent.
NOTE: Newer units have a 7/8" grommet located on the
rain shield, which would eliminate routing the harness
around the back corner.
