VENT ADAPTOR KITS
The Vent Adaptor Kits provide a transition from the appliance
to the flue and inlet pipes. The Single Flue Horizontal Vent Kit
(PVVK-FC) provides a transition for the piping. No cement is
needed to attach the adaptor to the fireplace. When installing the
flue piping, use the appropriate primer and cement to permanent
-
ly bond the joints and the pipes. Colinear Adaptor (part number
PVCA) provides a transition for the inlet air piping. See page 16.

ing PVC cement, cement all PVC joints of the flex vent kit to the remaining PVC vent run.
Vent Freezing Protection
When the vent pipe is exposed to temperatures below freezing
(i.e. when it passes through unheated spaces, chimneys, etc.) The
pipe must be insulated with 1/2 inch thick sponge rubber insula
-
tion, Armaflex-type insulation or equivalent. Insulating pipe is im
-
portant to avoid condensate icing.
For proper operation, the flue exhaust must extend 6 inches from
the outside wall before applying an elbow.
