BEFORE YOU BEGIN
Read this manual carefully before installing or servicing this
equipment. Improper installation, servicing or maintenance will
cause death, injury or property damage. Check the minimum
required safe distances from combustibles given on the outside of
each burner to make sure that the product is suitable for your
application. The minimum required safe distances from
combustibles is also found on page 9 of this manual. Installer must
be a licensed contractor of representative. After the installation is
complete, check product operation as provided in these
instructions.
Unpacking the Heater
Manpower Requirements
To prevent personal injury and damage to the heater, two persons
will be required to remove the heater from the carton. Both ends
of the heater should be lifted from the carton at the same time.
The burner box should be lifted by gripping the bottom of the box.
The reflector end of the heater should be lifted using the rear
moveable hanger.
Safety
Thin sheet metal parts, such as the reflector portion of the heater
and the various venting components, have sharp edges. To prevent
injury, the use of work gloves is recommended. The use of gloves
will also prevent the transfer of body oils from the hands to the
surface of the reflector.

Section 1 INTRODUCTION
About The Heater
The enerRadiant HST is a factory-assembled, gas fired, low-intensity
heating system. The system has been designed for easy installation
and will provide years of economical operation and trouble-free
service. Not only is infrared heat efficient, it also provides the most
comfortable conditions in open areas, such as garages.
Gas-Fired
means it uses clean-burning Natural or LP gas.
Low-Intensity
means that the radiant surface of the heat
exchanger tube does not glow red. Instead, it operates at a lower
temperature (less than 1000 F) and radiates energy at a lower
intensity per square foot of radiating surface. The lower
temperature and intensity levels are within a range that is most
effective in establishing and maintaining personal comfort levels.
An aluminum reflector directs the radiant energy downward to the
occupied area.
Radiant
refers to the energy radiated by the enerRadiant HST
heater. Because the energy is in the form of infrared rays, it does
not directly heat the air. Instead, the rays heat objects such as the
floor, cars, machines and people. The warm objects, in turn, heat
the air. These combined features are the key to the exceptional
comfort and fuel efficiency provided by the enerRadiant HST
heater.
