Venting Installation
Your IHP appliance must be vented to the outside in accordance with the
current edition of the National Fuel Gas Code ANSI-Z223.1 (In Canada,
the current CAN/CGA B149.1 installation code).
This appliance requires a 3” diameter listed flex liner. The vent should
terminate with a listed direct-vent termination cap. The chimney should be
sealed around the cap to prevent air and rain from entering the chimney.
Adhere to the vent manufacturer's instructions for installation and vent
termination. These appliances are approved for use with the following
vent kits.
Simpson Dura Vent -
Flex Liner 3" X 35' - #3DFA-35
Adaptor w/ Flashing - #46DVA-GK
Termination Cap - #46DVA-VCH With #460 DVA-VWG
Termination Cap - #460DVA-VC
Co-Linear Kit w/ 3" X 35' Flex Liner (Intake and Exhaust), Adaptor, Flashing
and Termination Cap - #46DVA-CL33
Preparation For Flex Liner Installation
The liner connector plate can be removed (as shown in
Figure 6)
to make
it easier to connect the flex liners to the intake and exhaust collars. Re-
install the liner connector plate when the insert is placed in the fireplace.
NOTE: Ensure gasket on connector plate is not damaged before re-installing.
