Vent Information and Diagrams
A. Approved Pipe
This appliance is approved for use with Hearth & Home
Technologies DVP and SLP venting systems. Refer to
Section 16.B for vent component information.
DO NOT mix pipe, fi ttings or joining methods from differ-
ent manufacturers.
The pipe is tested to be run inside an enclosed wall.
There is no requirement for inspection openings at each
joint within the wall.
WARNING! Risk of Fire or Asphyxiation. This appli-
ance requires a separate vent. DO NOT vent to a pipe
serving a separate solid fuel burning appliance.
B. Vent Table Key
The abbreviations listed in this vent table key are used in
the vent diagrams.

C. Use of Elbows
Diagonal runs have both vertical and horizontal vent as-
pects when calculating the effects. Use the rise for the
vertical aspect 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, one foot of diagonal is equal to 21,6 cm horizontal
run and 21,6 cm vertical run. A length of straight pipe is
allowed between two 45º elbows (see Figure 7.1).

D. Measuring Standards
Vertical and horizontal measurements listed in the vent
diagrams were made using the following standards.
• Pipe measurements are shown using the effective length
of pipe (see Figures 7.2 and 7.3).
• Measurements are made from the appliance outer wrap,
not from the standoffs.
• Horizontal terminations are measured to the outside
mounting surface (fl ange of termination cap).
• Vertical terminations are measured to bottom of
termination cap.
• Horizontal pipe installed level with no rise.

General Rules:
• When penetrating a combustible wall, a wall shield
fi restop must be installed.
• When penetrating a combustible ceiling, a ceiling fi restop

• Horizontal runs of vent do not require vertical rise;
horizontal runs may be level.
