run on the outside of a building may be, but are not required to be, installed inside a chase.
high temp caulk or stuffed with unfaced insulation. If the
appliance is being installed on a cement slab, a layer of
plywood may be placed underneath to prevent conducting
cold up into the room.
C. Clearances
Construction of the chase may vary with the type of building.
These instructions are not substitutes for the requirements of
local building codes. Local building codes MUST be checked.
Chases should be constructed in the manner of all outside
walls of the home to prevent cold air drafting problems.
The chase should not break the outside building envelope
in any manner.
Walls, ceiling, base plate and cantilever floor of the chase
should be insulated. Vapor and air infiltration barriers should
be installed in the chase as per regional codes for the rest
of the home. Additionally, in regions where cold air infiltration may be an issue, the inside surfaces may be sheetrocked
and taped for maximum air tightness.
T o further prevent drafts, the wall shield and ceiling firestops
should be caulked with high temperature caulk to seal gaps.

vinyl or non-vinyl siding and soffits. 1. There must be 3 feet minimum
between termination caps. 2. All mechanical air intakes within 10 feet
of a termination cap must be a minimum of 3 feet below the termination
cap. 3. All gravity air intakes within 3 feet of a termination cap must be
a minimum of 1 foot below the termination cap.
Figure 4.4 Minimum Clearances for Termination
NOTE 3: Local codes or regulations may require different
clearances.
NOTE 4: Termination caps may be hot. Consider their proximity
to doors or other traffic areas.
NOTE 5: Location of the vent termination must not interfere with
access to the electrical service.
WARNING: In the U.S: Vent system termination is NOT permit-
ted in screened porches. You must follow side wall, overhang
and ground clearances as stated in the instructions.
In Canada: Vent system termination is NOT permitted in screened
porches. Vent system termination is permitted in porch areas with
two or more sides open. You must follow all side walls, overhang
and ground clearances as stated in the instructions.
Heat & Glo assumes no responsibility for the improper performance of the appliance when the venting system does not meet
these requirements.
CAUTION: IF EXTERIOR WALLS ARE FINISHED WITH VINYL SIDING, IT IS SUGGESTED THAT A VINYL PROTECTOR KIT BE INSTALLED.

To Install the Heat Shield:
1. Determine if the heat shield is required. Do so by measuring the vertical distance between the top horizontal
surface of the elbow to any combustible surface above.
If the distance is more than 4 inches, the heat shield is
NOT required. If it is 4 inches or less, the heat shield IS
REQUIRED. Install per the following steps. See Figure 4.5.

• If the combustible materials are not in place at the time
of install the elbow heat shield may be screwed to the

2. Fasten the shield in place using the four pilot holes provided in the part. The shield should be oriented such that
the 13 1/8 inch dimension (longest dimension) is running in the same direction the elbow is pointing. The
shield should be centered directly above the elbow, and
positioned so that it creates a 1/2 inch airspace between
the shield and the combustible surface. See Figure 4.6.
Refer to Cinch Pipe and Termination Cap installation instructions.
• Continue adding vent components, locking each succeeding component into place.
• Ensure that each succeeding vent component is securely fitted and locked into the preceding component in the
vent system.
• 90° elbows may be installed and rotated to any point
around the preceding component’s vertical axis. If an elbow does not end up in a locked position with the preceding component, attach with a minimum of two (2)
sheet metal screws.
C. Install Support Brackets

C. Measuring Standards
Vertical and horizontal measurements listed in the vent
diagrams were made using the following standards.
1. Pipe measurements are shown using the effective length
of pipe (see Figure 5.2).
2. Measurements are made from the appliance outer wrap,
not from the standoffs.
3. Horizontal terminations are measured to the outside
mounting surface (flange of termination cap) (see Figure 4.1).
4. Vertical terminations are measured to bottom of termination cap.
5. Horizontal pipe installed level with no rise.
Diagonal runs have both vertical and horizontal vent aspects when calculating the effects. Use the rise for the vertical aspect and the run for the horizontal aspect (see Figure 5.1).
Two 45
450 runs, one foot of diagonal is equal to 8.5 inches horizontal run and 8.5 inches vertical run. A length of straight
pipe is allowed between two 450 elbows (see Figure 5.1).
