Use a PEK series extension kit or follow installation method below for a double
pipe system. To install an outer pipe extension to the SWG power venter, the end
pipe cover on the power venter must be removed. Then, cut a 1 inch square notch
into the vent pipe extension before attaching the power venter. (See Figure 5) This
allows clearance for the adjustment damper. Install the needed pipe extensions and
terminate the outer pipe extension with the end pipe cover. (See Diagram B) The
table above shows minimum allowable clearances when using single or double pipe
systems. When the outer pipe is extended over the inner pipe, use the double pipe
guidelines when determining clearances. Figure 6 shows how the air ow pattern
through an SWG reduces the required clearances to combustibles.
NOTE: Vent pipe joints should be secured with at least three (3) sheet metal screws.
CLASS B AND CLASS L DOUBLE WALL VENT PIPE INSTALLATION
(Follow vent pipe manufacturer's listed or recommended clearances from combustible material.)
1. Using a hand crimper or a like device, crimp the inner pipe of the SWG power venter approximately 1"
long. (See Figure 7)
2. Attach the vent pipe over the crimped end of the SWG power venter inner pipe.
3. Secure the vent pipe to the SWG power venter inner pipe with at least three (3) #8 sheet metal screws.
Pre-drilling the holes through both pipes will allow easier fastening.
WIRING
NOTE: Refer to appropriate control kit for proper installation instructions.
Wire the power venter motor and controls in accordance with the National Electrical Code and applicable
local codes. UNIT MUST BE GROUNDED. Check ground circuit to make certain that the unit has been properly
grounded. The wiring should be protected by an over-current circuit device rated at 15 amperes. CAUTION MUST
be taken to ensure that the wiring does not come in contact with any heat source. All line voltage and safety
control circuits between the power venter and the appliance MUST be wired in accordance with the National
Electrical Code for class 1 wiring or equivalent.
