Make sure that the structure
to which the unit heater is to be mounted is
capable of safely supporting its weight. Under
no circumstances must the gas lines, the venting
system or the electrical conduit be used to support
the heater; or should any other objects (i.e. ladder,
person) lean against the heater gas lines, venting
system or the electrical conduit for support. Failure
to heed these warnings may result in property
damage, personal injury, or death.
Unit Heaters must be hung level from
side to side and from front to back. Failure to do so
will result in poor performance and/or premature
failure of the unit.
Ensure that all hardware used in
the suspension of each unit heater is more than
adequate for the job. Failure to do so may result in
extensive property damage, severe personal injury,
or death! Washers should not be used between the
unit nutsert and jam nut. Use of a washer may cause
the nutsert to become dislodged from the unit.
Refer to Figures 3A through 3E for suspension of units.
For unit sizes 300/400, pay special attention to the
orientation of the angle mounting brackets per Figures 3B
and 3E to ensure brackets sit flush on the bottom of the unit.
