NOTE: Vent pipe joints should be secured with at least three sheet 
metal screws. Use a PEK series extension kit or follow installation 
method below for a double pipe system. When the outer pipe of 
the SWG is extended over the inner pipe, use the double pipe 
guidelines for determining clearances.
INSTALLATION USING TYPE B VENT PIPE
1.  Using a hand crimper or a like device, crimp the inner pipe of 
the SWG power venter approximately 1" long. (See Figure 4)
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.
PEK-4HD EXTENSION KIT INSTALLATION 
INSTRUCTIONS (Optional)
(Includes an air adjustment damper plate)
1.  Remove the End pan from the SWG Venter. 
(See Figure 5)
2.  Using a pair of sheet metal cutters, cut the Damper Plate 
Adjustment Bracket. (See Figure 6) Then remove the 
Damper Plate and Adjustment Bracket.
3.  Install the Extension by starting the inner pipe into the 
attaching section rst, then lightly tap the end of the 
inner and outer pipe into the attaching section until the 
rib on the crimped end touches the attaching pipe. The 
lock seam of the pipe should be on the top of the pipe.
NOTE: The Extension Kit can be added onto the SWG 
Venter directly or by attaching equal lengths of pipe to the 
inner and outer pipes, then the Extension Kit can be added 
closer to the heating unit.
4.  Make sure damper plate rotates freely, then fasten the 
outer pipe with at least three (3) sheet metal screws.
