The CTCU heaters are fully automatic and operate 
from the external controls fitted on site. 
The only user controls at the heater are the:
Burner Lockout 
Reset Button ................ See Page 18, Section 11.3.3
Limit Thermostat Reset See Page 18, Section 11.3.2

When the heater has been switched on by the 
remote controls installed on site, the main burner will 
automatically turn on.
The burner control box will control the safe ignition 
of the flame.
All heaters require a constant gas and electricity 
supply which must not be interrupted during the 
normal operation of this heater.

The fan thermostat is located inside the access door 
at the top of the heater. See Page 28, Section 15.3.
This control ensures the heater does not blow cold 
air in the normal heating cycle.

The limit thermostat is located inside the access 
door of the heater. See Page 28, Section 15.3. This 
control protects the heat exchanger against 
overheating. 

The red warning light on the back of the heater will 
illuminate when the control has gone to lockout. This 
may be caused by flame failure. Press the reset 
button on the back of the heater (See Page 5, 
Section 4.1) or the remote reset if installed on site.
11.4 Lighting Instructions 

1. Ensure that the electrical and gas supplies to 

the heater are on. Check that the on site con-
trols are “ON”.

 The thermostat setting must be above the 

ambient temperature for the heater to operate.

2. The automatic firing sequence will begin as 

described on Page 16, Figure 9. The heater will 
now operate automatically under the control of 
the on site controls. Following long shut down 
periods, the control may go to lockout. See 
Page 18, Section 11.3.3.
