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. 13. Re-mount the front door along with the knurled screw on the heater. TOP VIEW EXHUAST OUTLET REAR VIEW LEFT SIDE FRONT VIEW Note: The 90° elbow may be used as a termination cap.

To change voltages, follow wiring diagram for correct voltage connections. Table C: Reduced Maximum Equivalent Vent Run Improper wiring connections can burnout the relay and blower motor. Venting The vent pipe must be the same size or one size 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 ensure 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 recommended 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. 4" DIAMETER LEFT SIDE Fig. 4: Draft Assembly 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...
