The Safety Alert Symbol is used to indicate a risk of per-

sonal injury.

Please familiarize yourself with these instructions before

attempting to install or operate this Radiant Heater.

ELECTRIC SHOCK HAZARD. Disconnect all power

before installing or servicing heater. Failure to do

so could result in personal injury or property dam-

age. Heater must be installed or serviced by a

qualified person in accordance with the National

Electrical Code, NFPA 70.

1. Clamps — Heaters are mounted by means of the mounting

clamp and 3/8” bolt assembly which is used as shown in Fig. 2.

Clamp assembly may be attached to heater by sliding over end

or by snapping over top of extruded frame section at any point

along its length (see Fig. 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 heaters are mounted adjacent to

each other in the same plane, note that distance between

mounting holes on framing to support heaters will be 41/4” min-

imum. When heaters are not in the same plane, i.e., set at an

angle to one another, distance between mounting holes in fram-

ing will be either greater or less than 41/4”.

3. Framing — Where an extensive installation is being made, the

use of continuous slot metal framing manufactured by several

concerns will be of assistance in saving time and money. The

framing is reusable.

4. Reflector Spacer Sheets — Where heaters are not mounted side

by side (see Fig. 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 temperatures are

encountered, it may be desirable to insulate behind heaters with

high-temperature fibrous insulation. A suggested method of

accomplishing this is indicated in Fig. 4.

6. Ventilation — Where solvents, water, etc. are being evaporat-

ed from work in process, it is necessary to provide substantial

quantities of ventilation air to carry away the resulting vapors.

FIRE HAZARD. Since Radiant heaters are capable

of developing high temperatures, extreme care

should be taken to:

A. Keep combustible materials at least 6” away

form sides and back of heater housing and its

supporting brackets and spaced far enough in

front of heater (heating element side) so thermal

radiation from the elements will not ignite com-

bustible materials.

B. If combustible materials are being processed,

stoppage of process should initiate immediate

heater shutdown and interception of residual

heat from radiant heaters (use radiation baffles

or move heaters away from work).

C. In the case of solvents of an explosive nature,

ventilation air must be in sufficient volume to

dilute the solvent vapor so that explosive mix-

tures cannot occur, refer to NFPA 86, Standard

for Ovens and Furnaces.

WIRING

ELECTRIC SHOCK HAZARD. Disconnect all power

before installing or servicing heater. Failure to do

so could result in personal injury or property dam-

age. Heater must be installed or serviced by a

qualified person in accordance with the National

Electrical Code, NFPA 70.

ELECTRIC SHOCK HAZARD. Any installation

involving electric heaters must be performed by a

qualified person and must be effectively grounded

in accordance with the National Electrical Code to

eliminate shock hazard.

1. Electrical connection to the Radiant Heater is made through the

3/4” diameter conduit opening in the terminal box.

2. Access to Radiant Heater terminals is obtained by removing

the terminal box cover.

3. Wiring should be run in flexible or rigid metal conduit and

must be installed in accordance with the requirements of the

National Electrical Code and such other local requirements as

may be applicable. Note: High temperatures will oxidize cop-

per. Do not use copper wire in connecting this heater. Stranded,

insulated, nickel-plated copper wire is recommended.

4. Wires supplying power to heating element terminals shall have

insulation rated for 150°C minimum.

High Temperatures will oxidize copper. Use only nickel-

plated copper wire for supplying power to heater. Do not

use aluminum conductors.

5. A sufficient length of this wire (not less than 12”) should be

used to extend from each heater terminal into a connection box

location where the temperature does not exceed 300°F.

6. Assemble terminal, screw and wire as shown in Fig. 5.

7. Hold terminal with pliers and tighten the terminal screw

securely with a screwdriver.

Note: Where circuit wiring is installed in locations of high

ambient temperature, conductors should be insulated in accor-

dance with requirements for temperature and voltage.

FIRE/EXPOSION HAZARD. This heater is not

intended for use in hazardous atmospheres where

flammable vapors, gases, liquids or other com-

bustible atmospheres are present as defined in the

National Electrical Code. Failure to comply can

result in personal injury or property damage.

Before energizing this heater:

1. Be sure all electrical connections are tightly made. Hold ter-

minal with pliers when tightening screw.

2. Be sure that all conductors are properly insulated.

3. Be sure that terminal box cover has been properly replaced,

and that secondary insulation bushings have not been omitted.

Standard Radiant Heaters are built to operate at 40 watts per sq.

inch on the element sheath. When it is desired to reduce radiant

intensity, one or more of the following methods may be used.

1. INPUT CONTROLLERS. These motor-driven cycling

devices can be used to vary heater output capacity from 4 to

100%. They are usually connected in holding coil circuit of

magnetic contactors. See Chromalox Radiant Heater Manual

for further information regarding Input Controllers and

Contactors.

2. SOLID STATE THYRISTOR POWER CONTROLLERS.

For best non-contact control of radiant heat, a Series #6

Chromalox Thyristor Power Controller with manual poten-

tiometer setting is recommended. Truly proportional output of

from 0 – 100% can be easily dialed-in to suit the particular

product or process requirements. The Series #6 panels are pre-

engineered, pre-packaged assemblies in an enclosure with cir-

cuit disconnect provided and ready for installation.

Maximum Ambient Temperatures —

Chromalox Radiant Heaters are not recommended for applica-

tions in ambient temperatures exceeding 450°F. Higher ambient

temperatures mean shorter heater life.

Maximum work temperature in a given time depends on sever-

al factors: Reflectivity of work, specific heat of work, mass of

work, kW input and losses from oven and time of exposure. As

work temperature increases, the work loses heat by radiation and

by convection to the surrounding ambient. Although it is a gener-

al principle of Radiant Heater application that work temperature

conventionally exceeds ambient temperature, in cases where

extremely high work temperatures are desired, it is necessary to

enclose the heaters in order to increase the ambient. If evaporation

of a liquid is desired as a result of increasing work temperature, it

is necessary to provide ventilation air in order to carry away the

evaporated liquid. Under carefully engineered circumstances, a

maximum work temperature of 600°F may be attained.

8. SERIES CONNECTION of Radiant Heaters of equal volt

and watt rating is permitted in all line voltages up to 600 volts.

In making such series connections it is necessary to observe the

“right” (series-parallel) connection rather than the “wrong”

(parallel-series) connection both shown in Figure 6. If heaters

are connected according to the “wrong” illustration, failure of

any heater will cause progressive failure of other heaters still

operating.

9. DELTA CONNECTIONS — When heaters occur in multiples

of three, they may be connected to, and balanced across, three-

phase lines. The most commonly used connection is the delta

connection illustrated in Figure 7.

Three phase Delta connections to minimize inductive effect in

conduits are made per this diagram. The rule: run all 3 three-phase

conductors in the same conduit as far as possible. For single-phase,

run only two conductors and follow the same rule.

MAINTENANCE

ELECTRIC SHOCK HAZARD. Disconnect all power

before installing or servicing heater. Failure to do

so could result in personal injury or property dam-

age. Heater must be installed or serviced by a

qualified person in accordance with the National

Electrical Code, NFPA 70.

To Remove Heating Element —

1. Remove terminal box cover 6.

2. Disconnect heating element from electrical leads.

3. Remove threaded fitting nuts 9and washers 8 .

4. Remove element support clips and secondary insulating bushings.

5. Lift out element.

To Install Element —

Observe instructions for removing element and proceed in

reverse order. Be sure to replace secondary insulating bushings.

Care of Reflectors —

Reflectors should be cleaned periodically. A mild soap and

water solution or fine cleaning powder is best although more dras-

tic means may be required if reflectors are badly soiled by chemi-

cal or other deposits. The reflector is aluminum. DO NOT use

alkali cleaners since alkalies will dull reflector. Mild non-alkaline

cleaners, such as used for scouring kitchen sinks, may be used.

Reflectors are replaceable and may be purchased from Chromalox.
