Installing Vent Pipe

A. Assembly of Vent Sections
This appliance requires PV-Flex venting for any run that
terminates horizontally. Four (4) in. Duravent B-type vent
is approved for vertical termination.
WARNING
Fire Risk
Exhaust Fumes Risk
Impaired Performance of Appliance
• Assemble pipe sections per B-vent manufac-
turer's instructions.
• Use support tabs for screws.
• Screws must not exceed one inch long and
must not penetrate inner lining.
• Pipe may separate if not properly joined.
B. Attaching Vent to Firebox
B-Type venting: Follow vent pipe manufacturer's instructions.
PV-FLEX venting: Use starter collar included with the PV-
FLEX10 and PV-FLEX20.
• Seal the PVFLEX-CONNECT to the PV-fl ex pipe sec-
tions by applying a 1/2 inch bead of high temperature
silicone around the inside edge of the PV-FLEX pipe
and then secure with six 1/2 inch self-tapping screws.

pieces together properly.
WARNING
Fire Risk.
Explosion Risk.
Combustion Fume Risk.
Use vent run supports per vent manufacturer's
installation instructions.
Connect vent sections per vent manufacturer's
installation instructions.
• Maintain all clearances to combustibles.
• Maintain specifi ed slope (if required).
Improper support may allow vent to sag or
separate.
D. Securing Vent Sections (PV-FLEX)
• Secure Flex Connect Starter Section to the exhaust
collar of the appliance with three 1/2 inch self-tapping
screws.
• For vent runs that require multiple sections of PV-FLEX,
a PVFLEX-CONNECT fl ex connector must be installed at
each point where sections of PV-FLEX are connected.
Note: Due to the positive pressure within the Gateway venting
system, when using PV-FLEX use a 1/2 inch bead of silicone
caulk on ALL pipe ends and connectors throughout the vent
run to ensure a completely sealed system.
