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, page 4, 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.
This symbol indicates a potentially
hazardous situation, which, if not avoided, may result in
personal injury or damage to the equipment.
1.
The heater must be permanently mounted.
2.
The mounting surface must be strong enough to:
a. Support the heater’s weight.
b. Provide sufficient stiffness to prevent excessive
vibration.
3.
The single bolt mounting is not designed for high dynamic
loads that can occur during transportation. For heaters that
are to be installed prior to transportation, it is recommended
that temporary blocking or strapping be used to limit
movement of the heater with respect to the mounting
structure. Inspection of the mounting bolt for correct
tensioning is also recommended after arrival at site to ensure
no loosening has occurred in transportation. The mounting
bolt/nut should be torqued to 65 – 75 ft-lbs, refer to Table 5 -
Recommended Torque Specifications, page 10.
4.
Install the bracket on the heater with hardware provided.
4.1
Orient the heater to its final position before tightening
all hardware.
4.2
In higher vibration installations use of a removable
thread locking compound such as Loctite
®
243™Blue
Threadlocker is recommended.
4.3
Correct tensioning of the mounting bolt will include
full compression of the split lock washer and
inspection for correct thread engagement. The
mounting bolt/nut should be torqued to 65 – 75 ft-lbs,
refer to Table 5 – Recommended Torque
Specifications, page 12
.
5.
The discharge air louvers are individually adjustable.
