PRE-INSTALLATION PREPARATION
GARAGE INSTALLATIONS
1. In a storage area, clearance from heaters to combustible materials must be such that the material shall not attain
a temperature above 160°F by continuous operation of the unit.
2. Maintain an 8 foot (2m) minimum clearance from the floor to the bottom of the heater. Refer to the current edition
of CSA−B149 for installation compliance codes.
RESIDENTIAL
These units are approved for residential garage or non−confined living space applications. For installation in a residential
garage or non−confined living space, unit must be installed so that burners and ignition source are located no less than
18" (457mm) above floor. Heater must be located or protected to avoid physical damage by vehicles. Refer to the current
edition of CSA−B149 for installation compliance codes.
In a confined area, the heater must be installed in accordance with the current edition of CSA−B149 for installation
compliance codes. Be sure to check with local codes and ordinances for additional requirements.
INSTALLATION
UNIT HEATER INSTALLATION
Unit is shipped ready for installation. Unit may be installed as shown in figure 2 or inverted 180° depending on desired
location as governed by clearances, vent connection, air direction, gas supply, electrical supply and service accessibility.
1. If installing unit in an inverted position − Remove and retain screws securing door and rotate door 180°. Secure with
retained screws. Rotate louvers directing airflow as desired.
2. Choose location for mounting brackets.
3. Remove and retain three screws along top edge (bottom edge when inverted) of
front of unit.
4. Align screw holes on mounting bracket with holes along top edge (either upright
or inverted) of unit. Secure one mounting bracket to front of unit
with retained screws. Secure other mounting bracket to back of unit with
screws provided in bag assembly containing flue transition.
5. To support unit, secure mounting bracket to ceiling joist or truss. Unit may also
hang on support rods as shown in figure 2.
VENTING INSTALLATION
Adequate facilities for supplying air for combustion and ventilation must be provided in accordance
with the current editions of ANSI Z223.1, section 5.3, and CSA−B149 for installation compliance
codes, or applicable provisions of local building codes.
All gas fired appliances require air to be used for the combustion process. In many buildings
today, there is a negative indoor air pressure caused by exhaust fans, etc. If sufficient quantities
of combustion air are not available, the heater or another appliance will operate in an inefficient
manner, resulting in incomplete combustion which can result in the production of excessive
carbon monoxide.
CAUTION Insufficient combustion air can cause headaches, nausea, dizziness, asphyxiation
or death.
If indoor air is to be used for combustion, it must be free of the following substances or the life of
the heat exchanger
will be adversely affected: chlorine, carbon tetrachloride, cleaning solvent, halogen refrigerants,
acids, cements and glues, printing inks, fluorides, paint removers, varnishes, or any other
corrosives.
