INSTALLATION:

All wiring to this equipment must be connected to the electrical source in strict accordance with National Electrical Code (N. E. C.), Canadian Electrical Code (C.E.C.), international and/or any local codes having jurisdiction.

FOR WALL MOUNTING:

Do not install the section closer than:

• 6-7/8 inches below a horizontal surface
• 12 inches to an adjacent vertical surface
• 36 inches to another heater
• 6 feet from the floor

For angle positioning, the heater should not be directed toward any vertical surface closer than 6 feet.

The heater is to be mounted horizontally.

IMPORTANT: For Wall-Mounted heaters, insert the positioning bolts through the slots on both sides of the mounting bracket. DO NOT USE the ceiling mounting hole when mounting a heater on a wall.

Once the heater is mounted to the wall, position the heater to the desired angle between 20° and 45° downward from the horizontal, limited by the slot length. Tighten the two positioning bolts to secure the heater.

WARNING! Risk of fire. Do not position any heater at an angle not allowed by the slotted hole (20°-45°).

FOR CEILING MOUNTING:

Do not install the section closer than:

• 36 inches to a vertical surface for vertical mounting
• 6-7/8 inches to a vertical surface for angled ceiling mounting
• 12 inches to an adjacent vertical surface

• 6 feet from the floor

Ceiling mounted heaters can be mounted either through the Angled-Mount Positioning Bolt Location or the Ceiling-Mount Only Positioning Bolt Location.
