Hang the Heater

Residential garages come in a variety of sizes, shapes, styles and methods of construction. Because of all these variables, it is not possible to include mounting hardware with the Mr. Heater MHT heater. Although wooden rafters and joists are the most common overhead structural members in residential garage applications, other structural configurations are also illustrated below.

In the typical suspension methods shown below, lengths of chain are shown as a means of lowering the heater. However, for most residential applications it may not be necessary to lower the heater. Instead, it may be possible to screw hook-type hardware into the underside of a beam. The exposed hook could directly engage one of the two mounting holes in the front fixed hanger, while another hook could engage in one of the three suspension loops of the rear movable hanger.

Whichever method of suspension is selected, the two required suspension points must be capable of supporting a minimum of 150 pounds each.
