5.Terminate vent at least 6 ft away from adjacent walls.

6.DO NOT terminate vent closer than 5 ft below roof overhang.

7.The vent terminal requires a 12 in. vent terminal clearance from the wall.

8.Terminate vent at least 1 ft above grade, including normal snow line.

9.Multiple direct vent installations require a 4 ft clearance between the ends of vent caps located on the same horizontal plane.

WARNING: The Commonwealth of Massachusetts requires that sidewall vented heaters, installed in every dwelling, building or structure used in whole or in part for residential purposes, be installed using special provisions as outlined on page 55 of this manual.

Canadian Installations

Refer to latest edition of the B149 Installation Code. A vent shall not terminate:

1.Directly above a paved sidewalk or driveway which is located between two single-family dwell- ings and serves both dwellings.

2.Less than 7 ft (2.13 m) above a paved sidewalk or paved driveway located on public property.

3.Within 6 ft (1.8 m) of a mechanical air supply inlet to any building.

4.Above a meter/regulator assembly within 3 ft (915

mm)horizontally of the vertical centre-line of the regulator.

5.Within 6 ft (1.8 m) of any gas service regulator vent outlet.

6.Less than 1 ft (305 mm) above grade level.

7.Within 3 ft (915 mm) of a window or door which can be opened in any building, any non-mechani- cal air supply inlet to any building or the combustion air inlet of any other appliance.

8.Underneath a verandah, porch or deck, unless the verandah, porch or deck is fully open on a mini- mum of two sides beneath the floor, and the distance between the top of the vent termination and the underside of the verandah, porch or deck is greater than 1 ft (305 mm).

Venting Installation Tips

Support piping:

•horizontal runs—at least every 5 ft (1.5m)

•vertical runs—use braces

•under or near elbows

WARNING: Examine the venting system at least once a year. Check all joints and vent pipe connections for tightness, corrosion or deterioration.

Venting Configurations

For heaters connected to gas vents or chimneys, vent installations shall be in accordance with the NFGC (U.S.), or B149 (Canada), or applicable provisions of local building codes.

Vertical Venting (Category IV)

CAUTION: This venting system requires the installation of a condensate drain in the vent piping per the vent manufacturer’s instructions. Failure to install a condensate drain in the venting system will void all warranties on this heater.

Installation

The maximum and minimum venting length for this Category IV appliance shall be determined per the NFGC (U.S.) or B149 (Canada).

The diameter of vent flue pipe should be sized accord- ing to the NFGC (U.S.) and Appendix B of B149 (Canada). The minimum flue pipe diameter for con- ventional venting using Category IV, stainless steel
