A mounting system for mounting a pressure switch to a mounting body without using screws or brackets. The mounting system includes a support physically supporting the pressure switch on the mounting body, a conduit carrying a pressure signal from the mounting body to the pressure switch, and a connector extending between and connecting the support to the conduit. The support and conduit may have ends constructed of synthetic rubber to frictionally engage support and conduit mounts, and the support and conduit may have approximately the same length and/or the same cross-sectional shape. The mounting body may be a draft inducer, a condensate collector box, or a drain trap in a furnace.

A burner device (190) comprising an air intake, a burner head (192) including an ignition device, a body section (196) defining a fluid flow channel between said air intake and said burner head (192), and a gas injector (205) for injecting combustible gas into said fluid flow channel. The burner head (192) is oriented such that its longitudinal axis is substantially perpendicular to the plane in which the channel is defined and in which fluid flows, in use, along said channel.

A fuel supply system for a gas burner assembly includes a fuel supply, a forced air supply, and an injection assembly positioned proximate the gas burner assembly for providing a flow of combustion air and fuel through an inlet into a fuel chamber. A pressure controlled valve is operably coupled with the fuel supply and the forced air supply, the pressure controlled valve being configured for stopping the flow of fuel when a pressure of the flow of combustion air drops below a predetermined pressure, potentially indicating a malfunction or failure of the forced air supply.

A fuel supply system for a gas burner assembly. The gas burner assembly includes an inner burner stage positioned concentrically within an outer burner stage. The fuel supply system includes a fuel supply for providing a primary flow of fuel through a primary fuel conduit and a single outlet control valve operably coupled to the primary fuel conduit. A first and second fuel supply conduit split off of the primary fuel conduit and are fluidly coupled with the outer burner stage and the inner burner stage, respectively. A shutoff valve is operably coupled to one of the first fuel supply conduit and the second fuel supply conduit and is configured for closing when a flow rate of fuel through the shutoff valve drops below a predetermined flow rate.

A temperature control appliance adapted for installation over an outdoor gathering area provides infrared, radiant heat or evaporative cooling modes. The radiant burner has a semi-cylindrical porous foam metal radiator element mounted in a housing to direct infrared heat to the gathering area. Evaporative cooling is provided by misting nozzles mounted on the burner housing.
