B.2 Mounting
1. The heater must be permanently mounted to a xed
location onto a wall or ceiling.
2. The mounting surface must be strong enough to:
– Support the heater’s weight.
– Provide sufcient 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, page11.
4. Install the bracket on the heater with hardware provided.
4.1 Orient the heater to its nal 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, page11.
5. The discharge air louvers are individually adjustable.
