department at 1-800-251-0001.  
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.  
The selection of the thermostat mounting location is  
critical to efficient and effective heater operation.  
When selecting installation locations for this  
heater ensure that the opening of any exterior or  
interior doors or windows will not violate mini-  
mum clearances or contact any heater compo-  
nents.  
The thermostat should be mounted about 5 feet  
above the floor where air can circulate freely  
around it.  
The thermostat should not be mounted directly  
to a cold exterior wall without an insulated  
mounting block.  
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.  
The thermostat should not be mounted in direct  
drafts.  
The thermostat should not be mounted directly  
below the installed the heater.  
The thermostat should not be installed at a  
distance that is farther from the heater than the  
length of the thermostat cable.  
In most cases the infiltration around your  
uninsulated entry doors and windows will provide  
enough air flow for efficient heater operation.  
2. HEATER MOUNTING INSTRUCTIONS  
Unrestricted air flow 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:  
After selecting the heater installation location and the  
thermostat location and after verifying and ensuring that  
all of the above placement requirements are fulfilled,  
mount the heater as follows:  
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 finished workshop or utility building.  
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 flanged (finished)  
side on the interior or the exterior of the building or  
do you want two vents so that both exterior and  
interior will be finished?) 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.  
An intake vent, or equivalent, from the exterior of  
the building and having an effective area of 75  
square inches must be located below the heater  
(preferably within 2 feet of the building’s floor).  
Openings equivalent to intake vent would be:  
partially open doors and partially open windows.  
2. Select a place as high above the heater as  
possible in accordance with the above require-  
ments and ensure that the vent or vents will not  
contact or interfere with existing building sys-  
tems (i.e., ducts, wiring, plumbing, etc.)  
Openings of this size (5 inch by 13 inch, or 3  
inch by 25 inch) will prevent dangerous heat  
buildup above the heater.  
3. Place the unfinished side of the vent against the  
wall in its elected location and trace its dimen-  
sions on the wall with a pencil or other suitable  
marker.  
Ensure that no gas lines or electrical wiring or conduits  
will interfere with mounting of the heater to the wall.  
4. Cut or otherwise open a hole in the wall, or walls  
for finished buildings, having the dimensions of  
the unfinished side of the vent.  
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  
5. Install the vent or vents as desired and retain  
with 4 suitable fasteners through the predrilled  
holes in vent flange.

B. Prepare to install the heater wall mounting bracket  
as follows:  
the bolt through the clip and bracket.  
F. Thread the hex nut onto the bolt and tighten  
securely.  
1. If the wall mounting bracket is to be attached to  
a stud and wallboard wall, refer to Figure 3 for  
dimensions, locate a stud, and drill two 1/8" pilot  
holes into the stud centerline. Use template for  
simplified installation.  
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.  
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 ma-  
sonry to accept the anchors.  
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.  
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.  
J. Connect thermostat wires to gas valve as shown in  
Figure 4.  
E. Position the heater as shown in Figure 3 and slide  
the heater mounting clip over the bracket and install
