Raypak recommends that this manual be reviewed
thoroughly before installing the D-2 Power Vent. If
there are any questions which this manual does not
answer, please contact your local Raypak
Representative.
THIS MANUAL SHOULD BE MAINTAINED IN LEGIBLE CONDITION AND KEPT ADJACENT TO THE
UNIT.
General Specifications
The D-2 Power Vent Assembly is tested and certified
to the latest edition of the American National Standard
ANSI Z21.56. standard for pool heaters, 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 181-401. 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 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.
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.
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.
NOTE: The D-2 Power Vent comes factory-wired for
120V, but can be field-converted for 240V operation.
See wiring diagrams.
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.
9. Re-mount the jacket top to its original position and
screw in the four screws holding it down to the appliance.
10. If the appliance is a 181, 182, 330 or 331, remove
the tabs underneath the power vent using a 5/16” nut
driver and relocate them closer to the center of the
Power Vent as shown in Fig. 1.
Fig. 1: Reposition the Tabs as Necessary (see step 10)
to hold the Power Vent in position. Note: While twisting
you may notice some roughness, this is due to a tight
seal between the 6” vent and the Power Vent flue box.
12. Re-mount the access panel.
11. Mount the Power Vent assembly bottom on the 6”
vent as shown below. Twist the assembly downward.
Snap the mounting brackets into their appropriate slot
13. Re-mount the front door along with the knurled
screw on the heater.
