installation instructions. FAILURE TO DO SO MAY
RESULT IN SEVERE OR FATAL INJURY AND/OR
POSSIBLE VOIDING OF THE WARRANTY.
1. Read and follow all instructions in this manual.
2. Heater is to be used only in atmospheres having an
ignition temperature higher than the heater’s maximum
rated operating temperature, as shown on the heater data
plate. Refer to applicable electrical codes for additional
information.
3. Heater to be used only in the hazardous locations
indicated on the heater data plate.
4. Heater is for dry, indoor use only. Do not immerse in water.
Do not store or use in areas exposed to rain or snow.
5. Maximum ambient operating temperature 104°F (40°C).
6. Heater is to be connected and serviced only by a qualied
electrician experienced with hazardous location equipment.
7. Installation and wiring of the heater must adhere to all
applicable codes.
8. Before opening any enclosures, disconnect the
heater from the power supply. Lock the switch in the
“OFF” (open) position and/or tag the switch to prevent
unexpected power application.
9. External surfaces get hot and can cause burns with
prolonged contact.
10. Operate the heater only while it is permanently mounted
in an upright position. Refer to the C.1 Mechanical,
page4 for details.
11. Heater must be kept clean. When operating in a dirty
environment, regularly clean the nned tubes, top vents,
and keep bottom opening free of obstructions. Follow the
recommended maintenance procedures. Refer Section A.
Heater Maintenance Checklist, page3 for details.
12. Do not operate the heater in atmosphere corrosive to steel
or aluminum.
13. Use factory approved replacement parts only.
14. Conduit seals are not required in the heater’s factory
installed conduits.
15. A conduit seal is required within 6" (153mm) of eldentries.
16. If there are any questions or concerns regarding the heater,
contact the factory. Refer to the last page of this manual
for details.
C. INSTALLATION
All applicable codes must be adhered to. For optimum heating, the
heater should be installed as follows:
C.1 Mechanical
1. Location
1.1 The air discharge is not directed at a thermostat.
1.2 The air discharge is across areas of heat loss, such
as windows.
1.3 If equipment freeze protection is of importance,
locate heater as close to equipment as possible.
2. Mounting
2.1 Heater must be mounted level on a vertical surface
using the factory supplied mounting brackets such
that there are no obstructions to impede air inlet or
discharge.
2.2 The mounting surface must be strong enough to:
–Support the heater’s weight, refer to Section D.
Specications, page8.
–Withstand abusive situations such as transportable
installations of the heater.
2.3 Secure mounting brackets to vertical surface with the
top mounting hole 1.5" (38mm) below the desired top
surface height (Figure1, page4). Refer to Figure3,
page5, Figure4 and Figure5, page4 for physical
dimensions and Figure5, page6 for required
installation clearances. Mounting brackets are to be
spaced to match the slots in the rear panel of heater
cabinet.
2.4 After mounting brackets are secured, tilt the heater
and lower it onto the top tabs of the mounting
bracket such that the tabs go into the mounting
slots on the rear panel of the heater cabinet (Figure2,
page5).
1.5"

Installation
2.5 Carefully swing the bottom of the heater into the
mounting brackets so that it is resting on the bottom
tab (Figure2, page5).
2.6 Insert the securing screw through the bottom
mounting bracket tab and into the cabinet to keep
the heater from dislodging from the mounting
bracket (Figure2, page5).
2.7 CAUTION: Use fasteners with yield stress greater
than or equal to 58 ksi (400 MPa).

Installation
C.2 Electrical
WARNING
WARNING. Disconnect the power supply before
installation of the heater.
Lock the switch in the “OFF” (open) position and/or tag
the switch to prevent unexpected power application.
For heaters marked "IIC", insure to loosen the setscrew
before removing the cover. Installation and wiring of the
heater must adhere to all applicable codes.
1. General
1.1 Use only copper conductors and approved
explosion-proof wiring methods during installation.
Refer to the Section H.1 1-Phase, page12 and
Section H.2 3-Phase, page14, or heater data
plate for the voltage, amperage and wattage ratings
when sizing for the appropriate conductors. All
supply conductors should be rated for operating at
temperatures up to 194°F (90°C).
1.2 Supply voltage must be within 10% of the data plate
rating. External over-current protection is required
and must meet data plate ratings for voltage,
amperage and frequency.
2. Field Wiring
Heater has been supplied with an enclosure that has a
3/4"NPT or 1" NPT threaded opening to accommodate
the line conductors (see Figure3, page5 to for
connection details). Use wire connectors rated for
minimum 194°F (90°C).
NOTE: If remote thermostats other than the factory supplied are
used, ensure that they will not allow the room temperature
to exceed ambient temperature limitations of the heater
(104°F/40°C) and are suitable for the area’s hazardous
atmosphere classication. When using any control devices,
ensure that the voltage and amperage ratings match
the heater’s electrical ratings. If not, a contactor may
berequired.
3. Final Inspection
3.1 Before application of electrical power:
–Check that all connections are secured and comply
with the wiring diagram (see Figure 6 and Figure 7,
page7 and applicable code requirements,
–Conrm that the supply voltage and phase is
compatible with the data plate specications,
–Remove any foreign objects from the heater, and
–Ensure all external ttings and enclosure covers
aresecured.

Notes
* Or equivalent breaker as per local electrical inspection authority
requirements.
** For 3.6kW heaters rated T3 cabinet length is 49.5" (1256mm). 3.6kW
heaters rated T2A cabinet length is 31.3" (796mm).
*** Ensure supply wire size adheres to applicable local and national electrical
codes.
+ Available in 50 Hz only.
1. Heater is functioning normally if, at rated voltage, the current draw is within 10% of the
value in this table.
2. Operation at lower voltages that rated will result in reduced output and current draw.
Actual Output (kW) = [(Supply Voltage)2÷ (Rated Voltage)2] × Rated Unit Wattage (kW)]
3. Add suffix "T" for optional built-in thermostat. Thermostat not available on IIB+H2 models.
4. Add suffix "H" for high-temperature ambient storage option. High temperature storage
option is not available with thermostat option. Not available on IIB models.
