Installation For Horizontal Termination, Venting Installation

VENTING INSTALLATION

Continued

Installing Vent System in a Chase

A chase is a vertical box-like structure built to enclose venting that runs along the outside of a building. A chase is not required for such venting.

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 air space clearance between vent pipes and combustible materials and/or insulation is 1".

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 21 and 22). Snorkel kit VKS-47-K is also available (see page 19). Fol- low the same installation procedures used for standard horizon- tal termination with the exception of the external wall firestop. The snorkel termination does not require the use of the external wall firestop. If installing the snorkel termination below grade (basement applications), you must provide proper drainage to prevent water from entering the snorkel termination (see Figure 22). Do not back fill around the snorkel termination.

2.Vent pipes and fittings have special twist-lock connections. As- semble the desired combination of pipe and elbows to the appli- ance adaptor with pipe seams oriented towards the wall or floor.

Twist-lock Procedure: The female ends of the pipes and fittings have four locking lugs (indentations). These lugs will slide straight into matching slots on the male ends of adjacent pipes and fittings. (All connections must be sealed with high temperature silicone sealant as specified in the second warning statement on page 12.) Push the pipe sections together and twist one section clockwise approximately one-quarter turn until the sections are fully locked. See Figure 23. Note: Horizontal runs of vent must be supported every three feet. Use wall straps for this purpose.
