Abstract
In a direct gas-fire heater assembly having a generally box-like housing with a grate-like floor with a conventional gas regulator, a gas port mounted within a box-like shroud, the shroud having one side with a predetermined number, shape and size of primary combustion air inflow orifices to direct primary combustion air toward the gas port. A burner is mounted on the shroud over the gas port. The area above the burner and adjacent to it contains an ignition device and flame sense rod as well as a pair of opposed and particularly oriented flame shields on each side of the flame orifice. One each of a pair of opposed baffle-type deflectors is arranged on each side and just above the flame shield so as to form a combustion chamber as well as a path for secondary air flow to a downstream chamber. An additional flame deflector is formed on one baffle-type deflector to deflect the flame toward the blower area.
