A. Approved Pipe
This appliance is approved for use with Hearth & Home
Technologies DVP venting systems. Refer to Section
16B 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.
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 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).

B. Vent Table Key
The abbreviations listed in this vent table key are used in
the vent diagrams.
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 Figure 7.2).
• Horizontal terminations are measured to the outside
mounting surface (fl ange of termination cap) (see Figure
6.4).
• Vertical terminations are measured to bottom of
termination cap.
• Horizontal pipe installed level with no rise.
