Selecting a location for your heater:
The heater should he installed out of the reach of persons.
The direction of air flow should not be restricted by machinery, beams, etc., and the air flow should wipe exposed walls rather than blowing directly at them. When more than one heater is used in an area the heaters should he arranged so that the air discharge of each heater supports the air flow of the others to provide best circulation of warm air.
(see air flow chart)

Unpack & Inspect Your New Heater
Remove heater from the box and inspect it for any damage.
Verify you have received the universal wall/ceiling mounting bracket.

Hardware Needed
You will also need the following hardware, which can be purchased from your local hardware store or electrical supply house:

• adequate gauge and length of wire for your application
• proper size fuses or breakers to handle amperage
• proper wire connectors for your application
• fasteners appropriate for application that are strong enough to hold unit

For certain applications conduit may be required. Check local electrical codes.
Also, if you run the wiring in conduit and wish to be able to turn the heater, be sure to purchase enough flexible conduit to allow the heater to be turned.

Mounting Height
When the airflow of the heater is directed vertically or horizontally the minimum mounting height 6 feet from vertical side walls and 8 feet above floor (8 feet above floor for Canada). Mounting heights depend upon building utilizations and heater KW capacity.

Distance From Walls
Be sure to maintain 8″ minimum clearance to walls and ceilings.

Installing U-Mounting Bracket Hook
The GH Heater comes with U-Shaped bracket for installing the heater to the Ceiling/Wall bracket, allowing the heater to be quickly and easily installed.
