B.
INSTALLATION
All applicable codes must be adhered to. For optimum
performance, the heater should be installed as follows:
B.1
Location
1.
Ensure there are no obs tructions that may impede the
heater’s air inlet or discharge. Refer to Figure 1 - Mounting
Clearance, for minimum clearances.
2.
Ensure the air discharge is not directed at a thermostat.
3.
Ensure the air discharge is not directed towards areas of
heat loss, such as windows.
4.
Ensure the air discharge is directed along and at a slight
angle toward exterior walls.
5.
If equipment freeze protection is important, direct air
discharge at equipment while maintaining minimum
clearances.
B.2
Mounting
CAUTION
CAUTION.
Install heater no less than 5 inches (127 mm)
from walls and 6 inches (152 mm) from ceiling. Mount with
bottom of heater at least 2.44 m (8 ft) above floor or
grade.
1.
The heater must be permanently mounted to a fixed
location onto a wall or ceiling.
2.
The mounting surface must be strong enough to:
0.1 Support the heater’s weight.
0.2
Provide sufficient stiffness to prevent excessive
vibration.
