Concord CXA & CXS

Ideal's Concord CXA range of heat only, floor standing, gas boilers are available in both natural gas and LPG. The open flued boilers also feature an atmospheric burner.

The units incorporate on/off automatic ignition via an intermittent pilot. The modern control fascia includes warning lights for boiler on; overheat lockout and burner lockout. Inside, gas valves and controls are factory fitted as standard.

The CXS range incorporates high/low operation to provide high system efficiency. The range gives the choice of easy to operate models with simple analogue control. Optional remote indication kits provide volt free contacts for boiler performance monitoring.

Both CXA and CXS ranges are available in 9 model sizes from 40 kW to 120 kW. The 110 kW and 120kW models are suitable for installation in modular configurations – just 6 boilers can provide up to 720 kW output.

The CX range can be fitted onto induced-draught, fan dilution and mono-draught flue systems.
