SHORT RISE INSTALLATION - WALL
OUTLET
When terminating the exhaust system under the houses eaves,
the following requirements shall be fulfilled:
- in selecting locations for appliance and vent, take into con-
sideration the NPFA 211 6-3.5 rule for distance of exit terminal
from window and openings
- run the vent vertically up the wall, ensuring to maintain a mini-
mum of 3" (80 mm) clearance between the wall and vent
- a wall band must be installed just above the tee and at least
every 6' (180 cm) of vent rise or, if the rise is inferior, at the end
of the vertical run
- after a rise of at least 5' (1.5 m), install a 90° elbow aimed out
from the building wall
- attach a 45° elbow to the 90° elbow, aiming the second elbow
down toward the ground. Terminate the vent with a collar with
screen fastened to the 45° elbow
- the end of the vent pipe system must be at least 12" (30 cm)
from the wall and 24" (60 cm) below the eave

PRODUCT INFORMATION, INSTALLATION AND MAINTENANCE
This configuration will help prevent blockage of vent by snow
drifts. Also the minimum vertical run of 5 feet (1.5 m) ensures the
ventilation of the exhaust in the event of a power failure, and al-
low for easier cleaning through cleanout on tee.
a
Certain local code restrictions may apply. Check with
Local Officials first before installing.
Strictly observe the PL Vent manufacturer's safety spec-

THE MANUFACTURER.
a
Double wall PL vent requires a minimum clearance to
combustibles according to the manufacturer's safety
specifications and the use of listed wall thimble, fire
stop or roof flashing where applicable.
Do not place joints within wall pass-throughs.

MINIMUM FLUE VENT CONFIGURATION
Horizontal installations that terminate without any vertical sec-
tions of pipe are approved; however, it is recommended that a
minimum of 5' (1.5 m) of vertical be included in the vent system.
Having a vertical section in the venting will help prevent smoke
from exiting the appliance during power failures.
It is required that outside air be installed with this venting con-
figuration to reduce smoke and creosote smell in the room in the
event of power failure.
