DESCRIPTION
The Bantam Ecotherm is a room sealed gas wall heater which circulates warm air by convection. It is manually
ignited by a combined piezo igniter and gas tap which has OFF, PILOT and ON positions. The setting of the
thermostat and the room temperature determine if the main burner lights when the gas tap is turned to ON, after
lighting the pilot. A thermoelectric F.F.D. is fitted. Three different lengths of flue are available to enable the heater to
be fitted on walls from 75mm (3in) to 50Omm (20in) thick. The flues have eccentric ducts made from aluminium
coated steel sheet and a one piece terminal made from weather resistant aluminium. The heat exchanger is
assembled from pressings made from either aluminium coated or heat resistant sheet steel. The main burner is an
aerated ribbon type and the pilot burner is a target type. The case is made from stoved painted mild steel.
