FLOOR PROTECTION

MINIMUM CLEARANCES TO COMBUSTIBLE MATERIALS

The floor protector must be noncombustible material, extending beneath heater and to the front, sides, and rear as indicated below.

G = 2" (50mm)

H = 6" (150mm)

NOTE: In a corner installation, the floor protection must follow the above clearances.

VENTING TERMINATION REQUIREMENTS

1.Do not terminate vent in any enclosed or semi-enclosed area such as a carport, garage, attic, crawl space, under a sun deck or porch, narrow walkway or closely fenced area, or any location that can build up a concentration of fumes such as a stairwell, covered breezeway, etc.

2.Vent surfaces can get hot enough to cause burns if touched. Noncombustible shielding or guards may be required.

3.Termination must exhaust above air inlet elevation. It is recommended that at least 5’of vertical pipe be installed when appliance is vented directly through a wall to create natural draft, which will prevent the possibility of smoke or odor during appliance shutdown, and to keep exhaust from causing a nuisance or hazard by exposing people or shrubs to high temperatures. In any case, the safest and preferred venting method is to extend the vent vertically through the roof.

4.Distance from doors and windows, or gravity or ventilation air inlet into building:

a. Not less than 4' (1.2m) below;

b.Not less than 4'(1.2m) horizontally from; c. Not less than l’ (305mm) above.

5.Distance from bottom of termination and grade - 12" (305mm) minimum. This is conditional upon plants and nature of grade surface. The grade surface must be a noncombustible material (i.e., rock, dirt). Distance from bottom of termination and public walkway - 7' (2.1 m) minimum.

6.Distance to combustible materials - 2' (510mm) minimum. This includes adjacent buildings, fences, protruding parts of the structure, roof overhang, plants and shrubs, etc.
