Vent Information and Diagrams

Figure 7.1

A. Approved Pipe

This appliance is approved for use with Hearth & Home

Technologies SLP venting systems. Refer to Section

16.C 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.

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, 1 ft. (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).

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).

• Measurements are made from the appliance outer wrap,

not from the standoffs.

• Horizontal terminations are measured to the outside

mounting surface (flange of termination cap).

• Vertical terminations are measured to bottom of

termination cap.

• Horizontal pipe installed level with no rise.
