Flue Information

A. Flue Components
These models are approved to use Hearth & Home
Technologies series pipes, components and termination.
Approved components are labeled for identifi cation. This
pipe is tested and listed as an approved component of
the stove.
DO NOT USE FIELD-FABRICATED FLUE COMPO-
NENTS. Refer to the flue manufacturer's instructions.
This product is approved to be flued either horizontally,
through the side wall or vertically through the roof. You may
flue through a Class A or masonry chimney if an approved
adapter is used.
This gas stove is a balanced fl ue gas stove. All combus-
tion air must come directly from the outside of the building.
The fl ue pipe for this unit consists of an inner and an outer
pipe. The inner pipe carries the gas stove exhaust out of
the system, and the outer pipe brings fresh combustion air
into the gas stove.
• A round support box/wall thimble or heat shield
required when the fl ueing passes through a combustible
wall.
• A support box or ceiling fi restop
fl ueing passes through a combustible ceiling.
• Roof fl ashing and a storm collar are required when fl ueing
passes through the roof.
• Follow instructions provided with the fl ueing for installation
of these items.

B. Use of Elbows
CAUTION
ALL fl ue confi guration specifi cations MUST be followed.
• This product is tested and listed to these specifi cations.
• Appliance performance will suffer if specifi cations are not
followed.
Diagonal runs have both vertical and horizontal fl ue aspects
when calculating the effects. Use the rise for the vertical as-
pect and the run for the horizontal aspect (see Figure 7.1).
Two 45º elbows may be used in place of one 90º elbow.
On 45º runs, 12 in. (305 mm) of diagonal is equal to 8-1/2
in. (216 mm) horizontal run and 8-1/2 in. (216 mm) vertical
run. A length of straight pipe is allowed between two 45º
elbows (see Figure 7.1).

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
edge of termination cap. See Figure 7.3.
• Horizontal pipe should be installed level with no rise.
