Abstract

A gas flow control (10) for a gas fire and heater comprising a body (12) having a gas inlet (14), a first (50) and second (66) outlet each having a control valve, a first (40) and second (52) pilot outlet each for a pilot light, and a first (18) and second (32) safety valve maintainable in an open position when an associated pilot light is lit, the control further comprising flow channels between the first and second control valves and respectively the first and second safety valves thereby enabling gas flow to the control valve of the first and second outlet when the associated first and or second safety valve is open.
