ATTENTION: ALL CANADIAN CONTRACTORS/INSTALLERS: Before installing this heater into a multi-family hi-rise exceeding four stories, contact the local building code inspector to verify the building construction complies with the Progressive Collapse requirements as listed in the National Building Code of Canada 2005.

1. As you face the heater, the clearance to a side wall on the right side is 0” (Fig. 2), and the left side is 1” (Fig. 2).

2. The minimum clearance from the top of the heater to the ceiling or any projecting overhang is 10”. (See Figure 2).

3. The minimum clearance from the bottom of the heater to the floor, or the top surface of carpeting, tile, etc. is 0”.

(See Figure 2).

4. 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.

5. The minimum clearance from the edge of the vent cap to any overhanging obstruction, perpendicular side wall, or corner of building is 12”. (See Figure 1).

6. Vent cap must be located at least 9” from any opening that would allow combustion products to enter the building, windows, doors, etc., and 12” above the ground or shrubbery (See Figure 1).

Do not install vent cap in a window well. Provisions must be made to prevent snow accumulation from infringing on vent cap clearances.

7. Clearances around vent cap must be maintained to assure adequate combustion and ventilation air.

8. Clearances listed are minimum. Adequate accessibility clearances for servicing must be maintained.

9. RESIDENTIAL GARAGE INSTALLATION:

Gas utilization equipment in residential garages shall be installed so that all burners and burner ignition devices are located not less than 18 inches (46 cm) above the floor. You must build a platform 18” above floor, the full width and depth of the heater, including the rear trim kit. HEATER IS NOT DESIGNED TO HANG ON WALL.

Unit should be located or protected so it is not subject to damage by a moving vehicle. Use care in selecting a good location within the garage. DO NOT locate the appliance where heated air will be directed onto a nearby parked vehicle. Paint may discolor or rubber may harden and crack. DO NOT allow open or closed containers of paint, gasoline or other liquids having flammable vapors to be stored or used in the same area as the heater
