VENT ADAPTOR KITS
The Vent Adaptor Kits provide a transition from the fireplace to the
flue and inlet pipes. The Single Flue Horizontal Vent Kit (PVVK-
FC) provides a transition for the flue piping. No cement is required
to attach the adaptor to the fireplace. When installing the flue pip
-
ing, use the appropriate primer and cement to permanently bond
the joints and pipes. Colinear Adaptor (part number PVCA) pro
-
vides a transition for the inlet air.

Once length is determined, install two (2) 10 x 1/2” screws into the adaptor assembly to secure the adaptor assembly to
the flex hose. Using 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.
