WARNING

IMPROPER ORIENTATION OF THE HEATER 

COULD AFFECT THE SAFE AND RELIABLE 

OPERATION OF THE HEATER.

7.0  THERMOSTAT INSTALLATION

7.1 

FACTORY  INSTALLED  -  For  shipping 

purposes the thermostat well (located at back 

of unit) has not been installed.
Position thermostat bulb perpendicular to 

housing being careful not to kink the capillary. 

Slide well over bulb and screw into place. Make 

sure that a minimum 5 threads engagement is 

achieved.

7.2 

FIELD  INSTALLED  KIT  -  Most  Norseman

TM

 

XB units are suitable for field installation of a 

thermostat kit with the operator shaft hole on the 

front side of the unit and plugged with a socket 

head cap screw. If a thermostat is to be field 

installed, check to verify that you have been 

supplied with the correct thermostat kit. Single 

phase heaters use a single pole thermostat 

as supplied in kit number XTKW04481. Three 

phase heaters use a double pole thermostat 

as supplied in kit number XTKW04483. Follow 

the instructions supplied with the kit.

8.0  WIRING

8.1  Whenever hazardous materials are present, 

ensure that the terminal housing covers are 

secure before powering the heater.

8.2 

Use supply wires suitable for 221°F (105°C).

8.3  Use approved conduit and conduit seals as 

required by the code for hazardous locations.

8.4  To provide maximum protection each 

Norseman

TM

 XB heater should be fused 

individually using the nearest standard fuse 

size which is not less than 120% of the 

expected line current.

8.5  All heaters come factory prewired and ready 

for direct connection to the power supply 

leads.
(a) Connect the power leads to terminals 

marked L1 and L2 for single phase and L1, 

L2 & L3 for three phase heaters as shown in 

Figure 9.

(b) Connect the ground wire to the ground 

connection located in the heater terminal 

housing.
