• This heater may be mounted on any wall; however,
it is recommended that the heater be mounted in
the middle of the wall opposite any overhead doors.
• When selecting installation locations for this
heater ensure that the opening of any exterior or
interior doors or windows will not violate minimum
clearances or contact any heater components.
• If an overhead door is installed in the building,
verify that the heater is not installed in such a
way as to interfere with door operation and verify
that the door in its open position will not reduce
clearances below the minimum requirements.
Never mount the heater in such a way that would
position the heater above an opened overhead
door.
• In most cases the inltration around your
uninsulated entry doors and windows will provide
enough air ow for e󰀩cient heater operation.
Unrestricted air ow during heater operation is
essential to prevent the area above the installed
heater from overheating. If your workshop/utility
building is tightly insulated (including windows, doors,
openings, etc.) the following ventilating methods must
be followed:
• A single exhaust vent is supplied with your heater
for your convenience. This vent must be located
above the heater (preferably at the highest point in
the building interior) and it must vent to the exterior
of the building. An additional vent is available from
the factory for those having a nished workshop or
utility building.
• An intake vent, or equivalent, from the exterior
of the building and having an e󰀨ective area of 75
square inches must be located below the heater
(preferably within 2 feet of the building’s oor).
• Openings equivalent to intake vent would be:
partially open doors and partially open windows.
• Openings of this size (5 inch by 13 inch, or 3 inch
by 25 inch) will prevent dangerous heat buildup
above the heater.
Ensure that no gas lines or electrical wiring or
conduits will interfere with mounting of the heater to
the wall.
Depending on local codes and requirements and the
installer’s skill level, the sizing and installation of gas
lines required to supply the heater may require the
assistance of a professional. If in doubt as to these
requirements, discuss the requirements of this manual
with the dealer from whom the heater was purchased
and your gas supplier, or call our customer service
department at 1-877-447-4768.
The selection of the thermostat mounting location is
critical to e󰀩cient and e󰀨ective heater operation.
• The thermostat should be mounted about 5 feet
above the oor where air can circulate freely
around it.
• The thermostat should not be mounted directly to
a cold exterior wall without an insulated mounting
block.
• The thermostat should not be mounted in direct
drafts.
• The thermostat should not be mounted directly
below the installed heater.
• The thermostat should not be installed at a
distance that is farther from the heater than the
length of the thermostat cable.
2. HEATER MOUNTING INSTRUCTIONS
After selecting the heater installation location and the
thermostat location and after verifying and ensuring
that all of the above placement requirements are
fullled, mount the heater as follows:
A. Determine how you wish to install the vent based
on the construction of the building and your
personal preference. (i.e., do you wish the anged
(nished) side on the interior or the exterior of the
building or do you want two vents so that both
exterior and interior will be nished?) If needed,
order an additional vent from the factory. Our
address and toll free phone number are on the rear
cover of this manual. Install the vent as follows:
1. See Figure 3 for dimensions and information on
the vent.
2. Select a place as high above the heater
as possible in accordance with the above
requirements and ensure that the vent or vents
will not contact or interfere with existing building
systems (i.e., ducts, wiring, plumbing, etc.)
3. Place the unnished side of the vent against
the wall in its elected location and trace its
dimensions on the wall with a pencil or other
suitable marker.
4. Cut or otherwise open a hole in the wall, or walls
for nished buildings, having the dimensions of
the unnished side of the vent.
5. Install the vent or vents as desired and retain
Page 7 Installation instructions and Owner’s
Manual.

holes into the stud centerline. Use template for
simplied installation.
2. If the wall mounting bracket is to be attached
to a brick or masonry wall, refer to Figure 3
for dimensions. Obtain two 1/4 inch (inside
diameter) expansion anchors and determine the
correct drill size to be used with them. Drill the
appropriate size holes in the brick or masonry to
accept the anchors.
C. Place the wall mounting bracket on the wall and
align the two through holes on the bracket with
the pilot holes or anchors. Install 1/4 inch by 2-1/2
inch lag screws through the bracket into the stud or
anchors. Tighten securely.
D. Locate heater mounting clip on back of heater and
select the 1/4” – 20 by 3/4” hex head bolt and 1/4” -
20 hex nut.
E. Position the heater as shown in Figure 3 and slide
the heater mounting clip over the bracket and install
the bolt through the clip and bracket.
F. Thread the hex nut onto the bolt and tighten
securely.
G. Ensure that the selected thermostat location
meets all of the above requirements. Refer to the
instructions that come with the thermostat for
additional grounding information and mounting
instruction.
H. If the wall is of stud and wallboard construction,
then use the #6 by 1 inch sheet metal screws,
included with the thermostat, and mount the
thermostat in the selected location.
I. If wall is brick or masonry, the appropriate
anchors must be obtained to accommodate
thermostat mounting screws. Use the back plate
of the thermostat as a template to mark the hole
locations, drill appropriate size anchor holes, install
the anchors, securely attach the thermostat using
the mounting screws.
J. Connect thermostat wires to gas valve as shown in
