Operating Instructions and Owner’s Manual
Mr. Heater | Gas-Fired Low-Intensity Infrared Heater
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 MHT 45 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 tube 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 tube heater.
