HEATER INSTALLATION
NOTICE: The images below refer to model HSRP37GL, but the same
details and positions also apply to HSRP37MT.
GENERAL INSTALLATION INFORMATION AND
REQUIREMENTS
The required minimum clearances to combustible surfaces are
illustrated in Table 3 on page 4. The front of the heater is installed at
the minimum required clearance to combustible surfaces and toward
open space, and then the other sides must have a minimum clearance
of 16 inches to combustible surfaces.
• 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 infiltration around your uninsulated entry doors
and windows will provide enough air flow for efficient heater
operation.
WARNING: ELECTRICAL GROUNDING INSTRUCTIONS: This
heater is equipped with a three-prong (grounding) plug for
your protection against shock hazard and should be plugged
directly into a properly grounded three-prong receptacle. Do
not cut or remove the grounding prong from this plug.
WARNING: Keep any electrical supply cord away from any
heated surfaces.
WARNING: Certain materials or items, when stored under
the heater, will be subjected to radiant heat and could be
seriously damaged.
HEATER 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:
• 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 build-up 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 Heatstar customer service department at 1-866-447-2194.
