7 Vent Information and Diagrams

A. Approved Pipe

This appliance is approved for use with Hearth & Home Technologies DVP venting systems. Refer to Section 17.B. for vent component information.

DO NOT mix pipe, ﬁttings 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 appliance 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.

Symbol	Description

V1	First section (closest to appliance) of vertical length

V2	Second section of vertical length

H1	First section (closest to appliance) of horizontal length

H2	Subsequent sections of horizontal length

C. Use of Elbows

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 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).

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 (ﬂange of termination cap) (see Figure 6.4.).

•Vertical terminations are measured to bottom of termination cap.

•Horizontal pipe installed level with no rise.

Horizontal

On 45° runs, 1 ft (.3 m) of diagonal is equal to 8-1/2 in. (216 mm) horizontal run and 8-1/2 in. (216 mm) vertical run.
