12.0 Supply connectors to the heater must be suitable
for 194°F(90°C). A flexible (BX) metal covered wire is
recommended for applications protected from outside weather
conditions.
13.0 For short circuit protection, heaters must be installed
withproper fast acting fuses or breakers as close as possible
to the amperage draw of the unit(s), in compliance with the
local electrical codes.
Heaters with quartz tube or quartz lamp typeheating
elements are suitable for horizontal mounting only.
Heaters with metal sheathed heating elements can be
mounted in any desired position.

For wiring (all units except the Type R unit), first removethe
top channel to install the conduit connector fitting and then
connect the supply and ground wires to the pigtail leads.
Re-install the channel and leave it in place unless removal
is required for servicing. The Type R unit has a moisture
proof housing enclosing the terminals of a “U” shaped metal
sheathed element. Use rigid conduit (½”) to ensure moisture
protection.
When making wiring connections to the heater DO NOT
pull power connection wires from endcover. Pulling the
wires could eliminate the expansion wire loop at the
element end connection and may result in damage to wire
insulation.

Follow this procedure and Fig. 2 when installing the tube
or lamp:
15.1
Disconnect power at source.
15.2
Remove the terminal covers at each end of the
heater.
15.3
Remove the keeper screw on one retainer bracket
and slide the ceramic element holder aside.
15.4
Feed the element lead wire through the hole in the
ceramic holder at the fixed end first. Slide the ceramic
holder removed in 15.3 over the element so that the
element is captured in both ceramic holders and then
reinstall the keeper screw.
15.5
Loosen the electrical terminal nut on the ceramic
blocks to permit connection of the power and lead wires.
15.6
To connect the element lead wires, slide the ceramic
holder sas far as possible toward the centre of the fixture
and loop the element wire over the electrical terminal
leaving
very little slack
in the wire. Note that the ceramic
blocks are designed to slide freely with element thermal
expansion and the
taut lead wires
help to secure the
element in place.
15.7
Connect the power wires to the electrical terminals
and install terminal covers.
15.8
Before energizing, wipe the quartz sheath and
reflector with a cloth or paper towel dampened with
alcohol.

INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS FOR
SERIES OKA – 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 OKA radiant heater is suitable for process heating 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. This heater is not intended for
use in comfort heating applications.
2.0
The OKA heater is available with metal sheathed, 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.
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.
6.0
When mounting, maintain a minimum clearance to
combustibles of 15”(381 mm) at sides, 10”(254 mm) at top and
12”(305 mm) at ends.
Heaters with quartz tube or quartz lamp
type heating elements are suitable for
horizontal mounting only. Heaters with
metal sheathed heating elements can
be mounted in any desired position.
7.0
For short circuit protection, heaters must be installed with
proper fast acting fuses or breakers as close as possible to the
amperage draw of the unit(s), in compliance with the local electrical
codes.

damage. All maintenance and installation
should be done by qualified personnel
incompliance with local codes.
