D. SETTING THE APPLIANCE

NOVUS B-VENT INSTALLATION INSTRUCTIONS

CAUTION:

Provide adequate clearances around the air openings into the combustion chamber and adequate accessibil- ity clearances for servicing and proper operation.

D. SETTING THE APPLIANCE

This appliance may be placed on a smooth combustible or noncombustible, continuous flat surface. When the appliance is installed directly on carpeting, tile or other combustible material other than wood flooring, the appliance shall be installed on a metal or wood panel extending the full width and depth of the appliance. Slide the appliance into position and level the appliance from side-to-side and front-to-back. Shim with noncombustible materials as necessary.

Secure the appliance by bending out the nailing flanges on each side of the appliance and nail to framing. The nailing flanges have been positioned 5/8 inch back from the front of the appliance to allow the addition of drywall.

WARNING!

To prevent contact with sagging or loose insulation, the appliance must not be installed against vapor barriers or exposed insulation. Localized overheating could occur and a fire could result.

E. VENTING

1.VENT HEIGHT

This appliance requires a 5” B-vent for operation. Never downsize pipe. It must be terminated above the roof line. Follow all B-vent requirements and installation instructions, including minimum clearances.

The minimum height of vent installation must be nine feet from the top or twelve feet from the base of the appliance. Horizontal run must never exceed 50% of the height of the vent system as shown in Figure 4.

2.ATTACHING VENTING

a.Assembling Vent Sections. Attach straight vent section to the top of appliance. Use only B-vent sections.

b.Attaching the Vent to the Collar Shield. Three tabs extend from the collar shield to the B-vent section. Screw the tabs to the B-vent section using the self-tapping ¼” screws supplied with the appliance.

c.Using Elbows. Elbows exceeding 45° from the vertical shall be considered horizontal and therefore adapt horizontal run limitations. See Figure 5.
