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.
