E6 Operating Instructions and Owner’s ManualHEATSTAR Gas Fired Infrared Workshop Heater
• 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.
• 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 1-866-447-2194. The selection
of the thermostat mounting location is critical to
efficient and effective heater operation.
• In most cases the infiltration around your uninsulated
entry doors and windows will provide enough air
flow for efficient heater operation.
1.1 Fresh Air for Combustion and Ventilation
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:
• 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.
• 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.
• Openings of this size (5 inch by 13 inch, or 3 inch by
25 inch) will prevent dangerous heat buildup above
the heater.
1.2 Thermostat Guidelines
• 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.
• 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.
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
fulfilled, 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 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.
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 unfinished 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 finished buildings, having the
dimensions of the unfinished side of the vent.
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:
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
E7 Operating Instructions and Owner’s ManualHEATSTAR Gas Fired Infrared Workshop Heater
for simplified 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
Figure 4.

PELIGRO: La intoxicación por monóxido de carbono
puede causar la muerte.
Intoxicación por monóxido de carbono:
Los síntomas tempranos de intoxicación por monóxido
de carbono se asemejan a la gripe, con dolor de
cabeza, mareos o náuseas. Si tiene estos síntomas,
es posible que el calentador no esté funcionando
correctamente. Tome aire fresco de inmediato. Haga
reparar el calentador. Algunas personas se verán más
afectadas por el monóxido de carbono que otras.
Por ejemplo, mujeres embarazadas, personas con
afecciones cardíacas o pulmonares, anemia, quienes se
encuentren bajo la influencia del alcohol o en la altura.
Los combustibles usados en equipos para licuar gas
propano, así como los productos de su combustión,
pueden exponerte a sustancias químicas, entre ellas el
benceno, que el estado de California reconoce como
causa de cáncer y de malformaciones congénitas
y otros daños al sistema reproductor. Para más
