FA Series

High humidity or saltwater atmospheres will accelerate heater corrosion and reduce useful life. Do not

install the heater in locations where water (in the form of rain, drips, or spray) could fall onto the gas

ignition components.

The suspension of the heater must conform to all applicable codes referenced in the safety section and

these instructions.

To ensure proper operation, the heater must be installed in a level horizontal position. The units are

designed to be hung with threaded rod via the four (4) threaded inserts on the top panel of the heater.

Determine desired mounting points, and mark the locations for the hanging points.

Prepare the mounting surface. If necessary, weld blocks, drill holes, or install additional bracketing

or steel channel.

Fasten beam clamp, screw hook, turnbuckle, steel channel, or other anchoring device to the

suspension points.

Determine the desired mounting height. Cut four pieces of 3/8”-16 threaded rod of equal length in

which the heater will be hung from. Ensure that the threads are not damaged during the cutting

process.

Using 3/8”-16 threaded rod, thread a nut up one end at a distance of approximately 1 inch. This is

the end that will be screwed into the heater.

Next, place a lock washer on top of the nut and thread the rod assembly into the unit heater’s

threaded inserts. A minimum of 2-3 complete threads must be exposed on the reverse side of the

threaded insert (approx. 9-10 turns), but no more than 20 turns, as this may cause the threaded rod

to collide with or damage the heat exchanger.

Tighten down the previously installed jam nuts to prevent the threaded rod from turning.

Attach threaded rod to prepared anchoring device. Adjust the threaded rod until the unit is level and

equal weight distribution is achieved. Threaded rod must be perpendicular with the unit. Do not

install threaded rods at an angle, as this can result in weakened structural integrity or undue noise.

3.0 Installation

WARNING

Improper suspension of the unit heater may result in collapse and being crushed.

Always suspend from a permanent part of the building structure that can evenly

support the total force and weight of the heater.

Failure to maintain minimum clearance to combustibles may result in ﬁre and/ or

explosion, property damage, serious injury or death. Always maintain minimum

clearances.
