FIRE HAZARD. Since heaters are capable of
developing high temperatures, extreme care
should be taken to maintain adequate spacing
between heater and combustible materials.
Failure to comply can result in personal injury
or property damage.
1. Clamps — Heaters are mounted by means of the
mounting clamp and 3/4" bolt assembly which is
used as shown in Figure 2. Clamp assembly may be
attached to heater by sliding over end or by snap-
ping over top of extruded frame section at any point
along its length. (See Figure 3) For proper heater
support, the maximum distance between clamps
must not exceed 48". On extra-long heaters, more
than two clamps are furnished.

2. Mounting Holes — When beaters are mounted ad-
jacent to each other in the same plane, note that
distance between mounting holes on framing to
support heaters will be 3-11/16" minimum. When
heaters are not in the same plane, i.e., set at an
angle to one another, distance between mounting
holes in framing will be either greater or less than
3-11/16.
3. Framing — Where an extensive installation is be-
ing made, the use of continuous slot metal framing
manufactured by several concerns will be of assis-
tance in saving time and money. The framing is re-
usable.
4. Reflector Spacer Sheets — Where heaters are
not mounted side by side (See Figure 4), reflector
spacer sheets can be used between heaters. These
reflector spacer sheets and companion reflectors
consisting of an extruded aluminum housing with
reflector sheet and mounting clamps are available.
Check factory.

5. Insulation — Where unusually high work tempera-
tures are encountered, it may be desirable to insu-
late with high temperature insulation. NOTE: An air
space should be left between backs of heaters and
insulation. (see Figure 4).
6. Ventilation — Where solvents, water, etc. are be-
ing evaporated from work in process, it is necessary
to provide substantial quantities of ventilation air to
carry away the resulting vapors.
IMPORTANT – In the case of solvents of an ex-
plosive nature, ventilation air must be in suf-
ficient volume to dilute the solvent vapor so
that explosive mixtures cannot occur. In order
to comply with the standards of safety required
Figure 3
by the insurance companies, ventilation protec-
tion and other facilities must be in accordance
with NFPA Bulletin No. 86, entitled "Standard
for Ovens and Furnaces". This Bulletin may be
obtained from the Association at 470 Atlantic
Avenue, Boston Mass., 02110
FIRE/EXPLOSION HAZARD. This heater is not
intended for use in hazardous atmospheres
where flammable vapors, gases, liquids or
other combustible atmospheres are present as
defined in the National Electrical Code. Failure
to comply can result in personal injury or prop-
erty damage.
