How to Install Natural Gas Garage Heaters How to Install Natural Gas Garage Heaters

Installing natural gas garage heaters, no matter what brand or type you have, involves the same three basic steps.

Step 1 - Mount the Heater

The mounting height of the heater should be 18 inches above the floor and mounted by a hanging bracket. Put the vent outlet, gas and electrical connections, to the right or left of the air moving fan. The fan should direct air towards the areas of maximum heat loss. It should not interfere with the proper circulation of air in the garage.

Step 2 - Pipe Size and Pipe Installation

Size the gas pipe referring to the manual for your gas garage heater in order to provide adequate gas pressure to the heater. Use proper joint compounds for making pipe connections and test for leaks before operating the heater. Install the gas piping according to applicable local codes. Adequately support the piping for the gas garage heaters.

Step 3 - Make the Electrical Connections and Venting

Mount the thermostat 5 ft above the floor on a vertical, vibration free surface. Keep it in an area where it is exposed to the average temperature air. Refer to wiring diagram in the installation manual for setting up all wiring connections.

The unit heater must be vented and comply with the local building codes. The ventilation should allow maximum combustion of the gas and proper venting.
