2. 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 1.0/1.95A 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.

3. INSTALLATION REQUIREMENTS

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 POWER VENT ASSEMBLY

Follow these instructions if the PowerVent venting system was purchased as an option 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 PowerVent stack adapter. Otherwise, install the PowerVent 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 PowerVent 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

PowerVent. 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 below.

MOUNTING POWER VENT ASSEMBLY

-(continued

11. Mount the PowerVent assembly bottom on the 6” vent as shown below. Twist the assembly downward. Snap the mounting brackets into their appropriate slot 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.

13. Re-mount the front door along with the knurled screw on the heater.

** NOTE: The 90° elbow may be used as a termination cap.

WIRING A POWERVENT ASSEMBLY TO AN APPLIANCE WITH IID IGNITION.

WARNING

: Disconnect all electrical power to the unit before servicing to avoid potential shock injury or damage to the unit. To change voltages, follow wiring diagram for correct voltage connections. Improper wiring connections can burnout the relay and blower motor.

VENTING

The vent pipe must be the same size or larger than what is indicated. The D-2 Power Vent is capable of 360-degree discharge rotation and operates with a positive vent static pressure and with a vent gas temperature less than 400°F.

The total length of horizontal run shall not exceed an equivalent of 40 feet including termination cap.

For all cases, each 90-degree elbow reduces the maximum horizontal vent run by 10 feet and each 45-degree elbow in the vent run reduces the maximum vent run by 5 feet. See the table below for maximum vent lengths using

90-degree and 45-degree elbows. The D-2 Power Vent uses positive pressure to push flue gases through the vent pipe to the outside. The vent must be installed to prevent flue gas leakage. Care must be taken during assembly to insure that all joints are sealed properly and are airtight.

The vent must be installed to prevent the potential accumulation of condensate in the vent pipes. It is recommened that: a) The vent be installed with a slight downward slope of not more than 1/4” per foot of horizontal run to the vent terminal.

b) The vent be insulated through the length of horizontal run.

For appliances installed in extreme cold climate, it is recommended that: a) The vent be installed with a slight upward slope of not more than 1/4” per foot of horizontal run to the vent terminal. In this case, an approved condensate trap must be installed per applicable codes.

b) The vent be insulated through the length of the horizontal run.

The Raypak Power Vent operates with a positive vent static pressure and with a vent gas temperature that avoids excessive condensate production in the vent and as such it is listed as a

CATEGORY III

appliance.

Exception: When a Power Vent is connected to a vertical vent of sufficient height to generate a negative draft in the system. Consult sizing guide or factory.

The D-2 Power Vent assembly is suitable for through the wall venting, and for connection to smaller size vent pipes and breeching other than the standard atmospheric heater.

THROUGH THE WALL VENT

The D-2 Power Vent assembly includes a wire harness, shown below, which provides quick connections with the respective controls in the heater control box. The harness is of sufficient length to fit the appliance for which it is sized.

Reference the wiring diagram supplied with each appliance for actual connections.

SEQUENCE OF OPERATION

On call for heat, the D-2 Power Vent fan (and appliance pump) start. When the flow switch circuits close, the ignition system consisting of an electronic spark module, pilot gas system and flame sensor, are energized. When draft proving switch closes and all safety circuits are proven, the automatic main gas valves will open and the heater will operate. When the operating limit circuit is satisfied, the heater will shut down.

10

START UP PROCEDURES

The water system, the gas system and the electrical system for the heater should be completed and checked as per the heater installation manual and associated documents.

EMERGENCY SHUTDOWN

SHUT OFF ALL POWER AND GAS, CALL

GAS UTILITY.

1. Turn on power to the heater with the manual main gas valve and pilot gas valve off. The electric power supply requirements are:

• Dual-voltage fan motor.

120/240 volt 60Hz 1.0/1.95 Amp fan motor for appliance sizes 181-401.

DRAFT PROVING SWITCH

The draft proving switch insures that the blower is operating. The switch is in the limit circuit and does not allow the ignition module to operate unless it is closed.

2. Check power connections.

3. Close heater power switch.

4. Set operating control to call for heat.

a. Fan motor starts, draft proving switch closes.

b. Heater pump starts, flow switch closes.

c. Ignition module energized.

d. Check for spark at gas pilot.

5. Turn operating control to end call for heat.

6. Wait a minimum of 60 seconds.

7. Open pilot gas valve.

a. Repeat procedure outlined in #4 above.

8. After pilot gas is proven and main safety shut-off valve is energized.

Main burners will ignite.

9. Heater will operate until call for heat is satisfied.

11.Restart unit and visually check all components for proper operation.

12.Check all vent connections and joints for leakage. Correct if found.

13. To restart unit after a failure, follow the procedures outlined above and other subsequent or related sections outlined in the heater manual.
