DVVK-4RE VENT KIT INSTALLATION INSTRUCTIONS (CONT'D)
Sealing 4-inch Diameter Flue Outlet Tube
Follow correct option according to venting method.
Connecting Directly to Fireplace
If the air inlet and flue outlet tubes are to be connected directly to
the unit (no rigid venting system is being used), then the gasket
provided must be used to seal the 4-inch flue outlet tube. Peel
the paper off the self-adhesive gasket and then wrap it around
the end of the tube (if tube was cut, it is recommended to use
cut end) as shown in Figure 66. Pull the gasket tight at all times
while wrapping it around tube. The gasket ends should align, to
form a complete seal. The overlapped section should NOT come
in contact with the seam in the tube. Apply high temperature
sealant to the opposite end of the tube (on the inside of the
tube). The end with the gasket will attach to the back of the unit.
Continue with Step 13.
Connecting to Rigid Vent System
If the air inlet and flue outlet tubes are to be connected to a rigid
venting system (and not directly to the back of the unit), then do
not use the gasket provided. High temperature sealant should
be applied to the outside of the 4-inch diameter flue outlet tube (if
tube was cut, it is recommended to use cut end) and to the inside
of the tube on the end that connects to the vent cap. Continue
with step 13.
