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.

The MHT tube heater may be installed in any of the three orientations indicated below. Select the heater orientation that is

best suited for the location that you have chosen for your heater.

•Horizontally

•Tilted 45° Right

•Tilted 45°° Left

NOTE: If the heater is going to be vented through the roof, be sure to carefully review the roof option installa- tion portion of this section. Ensure that the selected mounting site will satisfy the measurement param- eters (vent length not to exceed 25 feet) described in that section. Horizontal Installation

Horizontal Installation

1.Using S-hooks, attach two equal lengths of 2/0 chain, or equivalent, to the two uppermost holes in the front fixed hanger.

2.Slip the free end of both chains onto another S-hook, as shown.

3.The uppermost S-hook can now be installed on the suspension hardware that you have installed for suspension of the unit. An additional length of chain may also now be installed, if required, to lower the heater.

NOTE: The hook portion of hook-type suspension hardware may directly engage the two holes in the front fixed hanger and the center loop of the rear moveable hanger.

Rear Movable Hanger

45° Tilted Installation

2.Attach suspension hooks and/or chains to the selected suspension points of the heater.
