Vent Information
A. Venting Components
In order to comply with applicable codes and product
warranties, use only
Hearth & Home Technologies (HHT)
venting components
.
DO NOT USE FIELD-FABRICATED VENTING
COMPONENTS
. Refer to the venting manufacturer’s
instructions.
This product is approved to be vented either horizontally,
through the side wall or vertically through the roof. You may
vent through a Class A or masonry chimney if an approved
adapter is used.
This appliance is a direct vent heater. All combustion air
must come directly from the outside of the building. The
vent pipe for this unit consists of an inner and an outer pipe.
The inner pipe carries the appliance exhaust out of the
system, and the outer pipe brings fresh combustion air into
the appliance.
• A round support box/wall thimble or heat shield is required
when the venting passes through a combustible wall.
• A support box or ceiling firestop is required when the
venting passes through a ceiling.
• Roof flashing and a storm collar are required when venting
passes through the roof.
• Follow instructions provided with the venting for installation
of these items.
C. Measuring Standards
Vertical and horizontal measurements were made using the
following standards.
1. Pipe measurements are from center line to center line.
2. Horizontal terminations are measured to the outside
mounting surface (flange of termination cap) (see Figure
4.1) on page 9.
3.
Vertical terminations are measured to the top of the last
pipe before termination cap.
4. Horizontal pipe installed level with 1/4 inch rise per foot.

12 in.
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 45º elbows may be used in place of one 90º elbow. On
45º runs, one foot of diagonal is equal to 8-1/2 (216 mm)
inches horizontal run and 8-1/2 (216 mm) inches vertical run.
A length of straight pipe is allowed between two 45º elbows
(see Figure 5.1).
