CONQUEST 90 - Non-Direct Vent Termination Construction; Horizontal Vent Location Requirements

Horizontal vent terminations require
installing
a 2" PVC tee exactly 12"
from the outside wall. When using
3" vent pipe, reduce to 2" pipe
before penetrating the wall. Use a
maximum of 18" of 2" pipe inside
the wall.
See Figure 33.
An alternate horizontal termination
may be used as shown in Figure 34
to clear anticipated snow levels.
Raise the tee a maximum of 60"
above the wall penetration. Use
two 2" long sweep PVC elbows
and a length of 2" PVC pipe so
that the elbows are a maximum of
60" on center.
NON-DIRECT VENT TERMINATION
CONSTRUCTION
Select a point of wall penetration
where a minimum 1/4" per foot slope
can be maintained.
1. Extend the pipe 1-1/4" through
the wall.
2. Attach a PVC coupling at the
very outside of the wall.
3. If the wall penetration is too
close to the ground, attach a
long sweep PVC elbow and
length of PVC pipe to raise the
termination.
DO NOT RAISE
MORE THAN 60".
Attach
another long sweep PVC elbow
to the top of this extension.
4. Connect a length of PVC pipe
from this elbow to a standard
PVC tee. The inside edge of this
tee must be EXACTLY 12" from
the wall.
5. Secure the vertical pipe to the
wall with a pipe strap.
6. Insulate the exterior vertical pipe
length with minimum 1 /2" thick,
closed cell insulation, such as
"Arm-a-Flex" or "Rub-a-Tex."
HORIZONTAL VENT LOCATION
REQUIREMENTS
IMPORTANT:
MOISTURE IN THE
COMBUSTION PRODUCTS
CONDENSES AS IT LEAVES THE
TERMINATION. THIS CONDEN-
SATE CAN FREEZE ON EXTERIOR
WALLS, UNDER THE EAVES, AND
ON SURROUNDING OBJECTS.
SOME DISCOLORATION IS TO
BE EXPECTED. HOWEVER,
IMPROPER LOCATION OR INSTAL-
LATION CAN CAUSE STRUCTURAL
OR EXTERIOR FINISH DAMAGE TO
THE BUILDING.
