COMBAT® CABINET HEATERS INSTALLATION, COMMISSIONING, OPERATION AND SERVICE MANUAL

SECTION 11: USER INSTRUCTIONS 11.1 User Instructions

The COMBAT® Cabinet heaters are fully automatic and operate from the external controls fitted on site. The only user controls at the heater are the:

Fan Run Button - See Page 40, Figure 20.

Burner lockout reset button - See Page 41, Section 11.2.2.

Limit thermostat reset button - See Page 40, Figure 20.

WARNING

Electrical Shock Hazard

Disconnect electrical power before servicing.

Failure to follow these instructions can result in death or electrical shock.

to low fire. If the temperature rises to the second set point, the burner will turn off. The burner will come on again at either High or Low fire, depending on the thermostat set point.

Set the two stage thermostat to the desired temperature.

Modulating Operation

The on-site control for modulating burners is a temperature controller that provides a varying output signal dependant upon the ambient temperature to the control. The burner firing rate will continuously vary between the maximum and minimum setting. If the temperature rises with the firing rate set to the minimum, the burner will shut down. Set the operating temperature according to the instructions provided with the control.

11.2Common User Controls (all models) 11.2.1 Combination Fan/Limit Thermostat

The Combination Fan/Limit Thermostat is located at the top right side of the heater.

This control ensures the heater does not blow cold air in the normal heating cycle and protects the heat exchanger against overheating.

Figure 20: Fan/Limit Thermostat

11.1.1 Heater Operation

When the heater has been switched on by the remote controls installed on site, the main burner will automatically turn on. The burner control will control the safe ignition of the flame. When the heat exchanger is sufficiently heated, the fan thermostat turns on the main fan(s).

All heaters require a constant gas and electricity supply, which must not be interrupted during the normal operation of this heater.

NOTE: The fan will come on during burner firing for horizontally mounted and high-flow heaters and modulating burners.

11.1.2 Heater Operation (high/low or modulating)

The heater will operate as described in Section

11.1.1with these added features:

High/Low Operation

A second limit thermostat or a two-stage thermostat will be installed on site so that as the temperature reaches the first set point, the firing rate will reduce

If the air flow is reduced due to power failure, the limit thermostat will cause the burner to lockout.
