the appliance installation manual to determine maximum
length of pipe and fittings allowed.
b. Termination kit should be positioned where vent vapors will not
damage plants, shrubs, building materials, or air-conditioning
equipment, or where the vapors might be objectionable.
c. Termination kit should be located where it will not be aected
by wind gusts, snow build up, leaves or other debris that will
inhibit the function of the vent exhaust or intake.
2. Vent may be oriented as shown below as long as it is mounted
on a vertical wall.
3. If multiple vent kits are being installed, there must be at least 16”
horizontal space between the vent caps. To prevent possibility
of condensate freeze up, do not locate the vent kits above one
another.

4. Use the vent base as a template to locate the vent and intake
holes and four mounting holes. Cut two 3-7/8" diameter holes
for the exhaust and intake pipes. Drill four 3⁄16" diameter
holes for the mounting screws. Attach vent base to wall with
4 - #8 x 2" SS Screws.
5. Assemble the vent cap to the vent base with 4 - #8 x 2" SS Screws.

suitable material.
8. Extend intake and exhaust pipes to appliance, make sure to
attach intake and exhaust to the correct sides of the vent cap.
Use only Westlake Pipe & Fittings GVS-65 pipe, fittings, primer,
