Gas cooking and heating unit - has combustion gas flue leading to outside wall near air intake

摘要

The gas-fired cooking and heating unit is partic. for installation in a caravan, and has a cooking surface formed by a closed heat-transfer plate (4), partic. glazed ceramic, heated by a radiation burner (5,6). The burner comprises a plate, partic. ceramic, with pores or holes, and supplied from underneath with the necessary mixt. of gas and air. The combustion takes place in a chamber (7) connected by a flue (8) to an outside wall (11), which contains an opening (10,13) for the combustion air near the gas outlet, connected via a passage (16) to the burner air intake chamber (12). The heat-transfer plate can be at least partly masked by an adjustable guide surface, the intervening space being connected via a port to a room air collector conduit (24,26) containing a fan (27).
