BEFORE YOU START:
Plan your installation. Read these instructions and the fireplace
installation manual before installing unit and vent system. Set unit
in place and survey how best to vent the unit. After the vent con-
figuration has been decided, stretch the flex pipe components out,
then trim off what will not be needed.
Refer to the fireplace installation manual for information on vertical
venting requirements. The maximum length of vent when using
flex venting is 35 feet total. Contact your dealer or distributor for
information on flex vent extension kits that may be added to the
DVVK-4FV kit, in order to terminate up to 35 feet. Available exten-
sion kits include the DVEK-10 (10’ Flex) or the DVEK-25 (25’ Flex)
extension kits. The extension kits include connection hardware.
INSTALLATION OF THE VERTICAL FLEX TERMINATION KIT
WARNING
Ensure that the venting system exits the structure through
the roof and does not terminate less than 12 inches (305
mm) above the roof.
WARNING
Refer to your fireplace homeowner’s manual for the minimum
and maximum venting requirement of your fireplace prior to
installation. Failure to do so may cause a fire hazard.
WARNING
This flexible pipe termination kit is ONLY for vertical terminations.
WARNING
Any horizontal run section must have a 1/4 inch rise for
every one foot of run towards the vent termination. Never
allow the vent pipe to run downward. This could cause high
temperatures and may present a fire hazard. This vertical kit
may incorporate two 90 degree bends, but must terminate
vertically.
CAUTION
This flex vent kit can only be installed vertically off of the
unit and must terminate vertically.
WARNING
Because of sharp edges, always use gloves when handling
the flex vent components.
CAUTION
Vent connections should overlap a minimum of 1 inch for
proper sealing.
CAUTION
Always stretch and secure venting with metal strapping
secured with nails (nails and strapping not supplied) to
ensure that the flex vent runs remain true.
