A. Venting Components
In order to comply with applicable codes and product
warranties, use only following venting components:
• Hearth & Home Technologies (HHT)
• Security Chimney's Secure Vent Chimney System
• Selkirk Metalbestos
• AmeriVent
• Simpson Dura-Vent (SDV)

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
required when the venting passes through a combustible
wall.
• A support box or ceiling firestop
venting passes through a ceiling.
• Roof flashing and a storm collar are required when

B. Use of Elbows
ALL vent configuration specifications MUST be followed.
• This product is tested and listed to these specifications.
• Appliance performance will suffer if specifications are
not followed.
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° elbows may be used in place of one 90° elbow. On
45° runs, one foot of diagonal is equal to 8-1/2 in. (216mm)
horizontal run and 8-1/2 in. (216mm) vertical run. A length of
straight pipe is allowed between two elbows. (See Figure 5.1.)

C. Measuring Standards
Vertical and horizontal measurements were made using the
following standards.
• Pipe measurements are from center line to center line.
• Horizontal terminations are measured to the outside of
the mounting surface (flange of termination cap). See
Figure 4.1.
• Vertical terminations are measured to the top of the last
pipe before termination cap.
• Horizontal pipe installed level with 1/4 in. rise for every
12 in. of horizontal travel.
