7 Vent Information and Diagrams

A. Approved Pipe

This appliance is approved for use with Hearth & Home Technologies DVP and/or SLP venting systems. Refer to Section 16B 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 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.

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 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).

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 6.3).

•Vertical terminations are measured to bottom of termination cap.

•Horizontal pipe installed level with no rise.
