Assembly & Installation:
• Remove the heater and all of the packaging material from
the box.
• Check all of the packing material for loose parts and set
aside.
• Thoroughly inspect the heater for damage. If any is found
do not contact the place of purchase. Please call the
Manufacturer at 800-251-0001.
INCLUDED IN THE BOX:
• Heater
• Hanging bracket
• Mounting plate
• Swivel Plate
• Angle adjustment knobs
• Heater fastening bolts
• 4- 8 mm Nuts, Bolts and lock washers
To Assemble, use the 8 mm nuts, bolts and lock washers to the
attach the swivel plate and the Mounting Plate to the hanging
bracket See figure 1. The nut and lock washer should be on the
underside.
Next, Locate a space to hang the heater on the ceiling. The
clearance to combustibles outlined in the specifications table
on page 3 and should be located within 4 feet of your power
connection or the location of where you plan to mount the
junction box your heater will be supplied from.
Once a location has been selected, fasten the mounting bracket
and accompanying hanging kit with 4 appropriately sized lag
bolts/or wall anchors that can support the weight of the heater
(not included). The weight of your heater can be found in the
specifications table on page 3. The best option is to attach the
anchors directly into a solid surface like a joist or plywood. If
that is not available consult with your local hardware store for
other options. There are many different Drywall anchors or
masonry anchors that will work.
Once you have selected a location and mounted the hanging
brackets you can now hang the heater. It is recommend that
you have help for this step. While you or your helper is holding
the heater in place, Install the two large Phillips head bolts and
angle adjustment knobs. See figure 2. At this point the heater
should look like the photo on the front of this manual.

Mr. Heater Forced-Air Electric Construction Heater
Wiring information:
The heaters covered in this manual are designed to be installed
and serviced by only licensed trained professionals. Heaters should
only be installed on a dedicated 240 volt circuit with a 30 amp
double pole breaker. Refer to NEC code ANSI/NFPA NO. 70-2011 for
specifics.
Remote Thermostat:
Units equipped with a remote thermostat will need to have the
cradle for the thermostat mounted in an appropriate location.
Using two wall anchors, (not included) mount the Thermostat
cradle to the wall. Select a location within 3.5 feet of the
heater. The cradle should be mounted in a location as to not be
affected by the air flow of the heater. If possible do not mount
on an un-insulated wall or in direct sunlight. That may cause the
heater to cycle unnecessarily.
Operating Instructions and OwnerÊs Manual

Operational Information
Heat is created by electric current passing through coiled metal
elements bringing them up to very high temperatures. The
fan then passes room air over the hot elements exchanging
cold air for warm. The air moving over the coils keeps them
from reaching temperatures that are not safe for the normal
operation of the heater. Therefor it is important to keep all
combustible materials and any objects that may be sucked
into the fan blades at a safe distance (please refer to the
specification table for appropriate clearances). Make sure that
the fan blades remain unobstructed at all times. Keep unit clean
and dust free. Do not block unit intake or exhaust at any time.
If damage has occurred please refer to the parts listing in this
manual and contact the manufacturer for a replacement.
WARNING: The electrical circuit must be properly grounded,
failure to do so may result in electric shock or property
damage.
WARNING: Always plug or wire heaters directly into a wall
receptacle or appropriate junction box. Never use with an
extension cord or re-locatable power tap (outlet/power strip).
These Electric forced air heaters are specifically designed to
be permanently installed by hanging from ceiling or overhead
structure. Do not attempt to use them as a portable heater.
Starting Instructions
1. With the heater properly installed and the power supplied to the unit
move the heat selection knob to the setting you want. There are both
high and low settings, along with a fan only option. Refer to Figure 3,
for information about each setting.
2. Turn thermostat to desired setting. Clockwise will increase the set
point, counter clockwise will reduce the setting. An audible click can
be heard when the current temperature in the space is matched on the
dial.
3. The Heating element and fan will remain on until the temperature
setting is reached. The unit will cycle on and off as needed.
