They are rated to providecentral heating outputs of 11.7 kW (40,000 Btu/h) to 20.5 kW(70,000 Btu/h).The boiler has a cast iron heat exchanger and is supplied fullyassembled, complete with a white enamelled mild steelcasing.A door at the top of the casing front panel hinges down, revealingthe boiler thermostat control (and programmer, if fitted).The boilers are suitable, as standard, for connection to open-vented systems ONLY - an overheat thermostat kit is availableto allow the boiler to be used on sealed water systems.The systems may be:ï pumped or gravity circulating indirect DHW onlyï pumped central heating onlyï pumped central heating combined with either a pumped orgravity circulating indirect DHW circuit.
