7 Vent Information and Diagrams
A. Approved Pipe
This appliance is approved for use with Hearth & Home Technologies SLP venting systems. Refer to Section 16.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 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

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.

General Rules:
•When penetrating a combustible wall, a wall shield firestop must be installed.
•When penetrating a combustible ceiling, a ceiling firestop must be installed.
•Horizontal runs of vent do not require vertical rise; horizontal runs may be level.
