BUILDER'S CHOICE SERIES INSTALLATION INSTRUCTIONS
F. VENTING
WARNING - RISK OF FIRE!
Air space clearances must be maintained at all times.
WARNING - RISK OF FIRE!
The horizontal run of vent must have a 1/4” rise for every 1 ft. of run towards the termination. Never al- low the vent to run downward. This could cause high temperatures and may present a fire hazard.
Use only pipe supplied and listed for use with this appli- ance. See page 5 for a description of the listed compo- nents. See the directions on page 13 for assembling vent sections.
1.HORIZONTAL TERMINATION
a.Installing the Interior Wall Shield
Frame a hole in a combustible wall for an interior wall shield as shown in Figure 5. This shield maintains minimum clearances and prevents cold air infiltration.
b.Termination
Vent termination must not be recessed in the wall. Siding may be brought to the edge of the cap.
Install the cap as shown in Figure 6. The cap pipe sections should overlap the vent pipe by
Local codes may require the installation of a shield (product #CS) which prevents the cap from accidentally touching anything or anyone.
Figure 11 illustrates cap locations prescribed by current ANSI Z273.1 and CAN/CGA-B149 Installation Codes.
The termination cap height must meet all local and national codes and not be easily blocked or obstructed. If the hole being penetrated is of noncombustible materials, a 9” diameter hole is acceptable.
CAUTION:
Provisions shall be made to provide adequate com- bustion and ventilation air.
WARNING - RISK OF FIRE!
If you have chosen horizontal termination, be sure there are no present nor future obstructions from trees, bushes, snow drifts, etc.
