Installing Vent System in a Chase
A chase is a vertical
NOTICE: Treatment of firestops and construction of the chase may vary from building type to building type. These instructions are not substitutes for the requirements of local building codes. You must fol- low all local building codes.
Note: When installing in a chase, you should insulate the chase as you would the outside walls of your home. This is especially important in cold climates. Minimum clearance between vent pipes and combustible materials such as insulation is 1".
After framing the chase (see Framing on pages 6 and 7) install the vent system by following the installation instructions.
INSTALLATION FOR HORIZONTAL TERMINATION
CAUTION: Horizontally terminated venting con- figurations require one foot of vertical rise from the 45° elbow before any horizontal run can be made. Failure to meet venting requirements may cause performance problems and possible damage to the fireplace.
1.Determine the route your horizontal venting will take. Note: The location of the horizontal vent termination on the exterior wall must meet all local and national building codes and must not be blocked or obstructed.
WARNING: Do not recess vent terminal into a wall or siding.
Snorkel terminations are available for terminations requiring a vertical rise on the exterior of the building (see Figures 14 and 15). Snorkel kit SVK is also available (see page 17). Follow the same installation procedures used for standard horizontal termi- nations. If installing the snorkel termination below grade (base- ment applications), you must provide proper drainage to pre- vent water from entering the snorkel termination (see Figure 15). Do not back fill around the snorkel termination.
