Rayburn Gas 480CD Boilerside Flame Probe Pre-Mix Burner R5573

January 2007 saw the introduction of the first Rayburn central-heating cooker, incorporating a high-efficiency condensing boiler,

Although the boiler output is rated at 23kW/hr, it is also suitable for smaller heating systems, without any loss of efficiency. 

It is a room-sealed (balanced-flue), natural gas product, utilising twin, premix gas burners with centralised pcb solid-state controls.

Based on the popular 400series, it features two cast-iron ovens and large hotplate, with separate warming plate. An integral programmer provides flexible control over the cooking operations.

Oven-venting is achieved without an electric fan, by using natural convection through a small copper-tube terminating externally.
