Installation
Direct Vent Installation
Vent systems that terminate through a wall may comprise up to six
different components:
A - Termination PTKO-2 (2" length)
PTKO-5 (5" length)
PTKO-9 (5" length)
PTKO-2F (2" length)
PTKO-5F (5" length)
PTKO-9F (9" length)
B - Stucco Kits MSR (stucco frame)
MOSR (stucco can)
C - Flex sections PFL-1 (12" section)
PFL-2 (24" section)
PFL-3 (36" section)
PFL-4 (48" section)
D - Solid sections PEXT-1 (12" section)
PEXT-2 (24" section)
PEXT-3 (36" section)
PEXT-4 (48" section)
PEXT-6 (72" section)
E - Extensions PXT-3 (5" section)
PXT-10 (10" section)
F - 90° elbow PEL-90F/F
PEL-90M/M
Short Configurations:
For installations straight through the wall, use a 2" or 5" termination
(see above chart for Part #), and PXT-5 or PXT-10 to achieve the
desired length. The maximum horizontal vent run with no vertical lift
is 12".
See Figure 8.
Example:
A 10' section and elbow (PIHR-10) used in conjunction with 3 ft. flex
section (PFL-3) will, when extended in a chase, allow for a maximum
horizontal run of twelve and one-half feet from the centre of the
fireplace to outside wall and a minimum of 7'6" when retracted in op-
posite direction.
(See Figure 9.)
"D" flex sections and "E" solid sections may be used in conjunction
with one another to obtain different possible horizontal length instal-
lations. NOTE: Flex section must not exceed maximum horizontal
length of 3 feet.
Long Vent Runs:
For longer or more complex vent runs, vertical lift is required. First
ensure that the planned run is acceptable using the Vent Graph. Plan
out the required components using the chart above. You may be able
to use fewer components using the chart below.
