INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS FOR
SERIES OKB, OKD & OKH – INFRARED RADIANT HEATERS
FIRE/EXPLOSION HAZARD WARNING - During operation, take precautions to ensure that
combustible materials are always kept at a safe distance from the radiant energy. This heater is
not intended for use in hazardous areas where flammable vapours, gases or liquids or other
combustibles are present. Remember that objects placed under an infrared heater can take a while
to reach stabilized temperatures. If you are unsure of the suitability of the heater for the intended
application, check with the factory for recommendations. Failure to comply can result in personal
injury and/or property damage.
DESCRIPTION
1.0 The OKB, OKD & OKH radiant heaters are suitable for
comfort heating use in non-hazardous areas protected from rain,
snow or splashing, where heating element temperatures in excess
of 1382°F(750°C) will not present the risk of fire or explosion. The
heater does not present a safety hazard when it is installed, operated
and maintained in accordance with these instructions.
2.0 The heaters are available with metal sheath, quartz lamp
or quartz tube heating elements. Use heaters with metal sheathed
elements where there is heavy vibration or mechanical shock.
Quartz tube or quartz lamp elements are very fragile and require
extreme care in handling. Heaters utilizing quartz tubes or quartz
lamps are unsuitable for applications in locations where the risk of
heavy vibration or mechanical shock exists.
3.0 To avoid damage in transit, heaters with quartz lamp or
quartz tube elements are shipped with the elements not installed in
the fixture.
4.0 A minimum of handling of the quartz sheath is
recommended since any type of contamination on the sheath may
reduce service life.
INSTALLATION
The system designer is responsible for the
safety of this equipment and adequate back-
up controls and safety devices must be
installed. Failure to comply could result in
personal injury and/or property damage.
Heaters must be wired by qualified personnel
in compliance with local codes.
5.0 Verify that the nameplate voltage and wattage are suitable
for use on the available electrical power supply. Do not connect
the heater to an electrical supply voltage other than shown on the
product label.
6.0 Minimum space clearances from combustibles, when
heaters are horizontally mounted and installed, as listed in Table 1
following.
7.0 For chain mounting, install eye bolts supplied in the ¼-20
drilled and tapped holes located at the top of the cast aluminum
end plates. Use the locking nut to secure the eye bolt in the casting
at the preferred location. Fasten the chains to the eye bolts and
suspend the fixture from the ceiling ensuring that the minimum
clearances shown in Table 1 are maintained.

8.0 For rod mounting ¼”-20 threaded rods of suitable length
are to be installed in place of the eye bolts as in paragraph 7.0
above.
9.0 If flush mounting on a non-combustible surface, be sure to
slot the mounting holes (5/16” x ½” hole) to allow for heater
expansion.
10.0 These heaters are intended to be installed in a maximum
40°C ambient temperature.
For metal sheathed heaters, insulation
contamination or moisture accumulation can
cause fault to the element sheath generating
arcing and releasing molten metal. Install
proper ground fault protection to prevent
personal injury and/or property damage.
