3.11 BURNER
Figure 16: Burner
This appliance uses a single cylindrical burner installed vertically into the cavity located in the center of the heat exchanger.
The burner consists of a round mounting flange welded to a mixing tube. The top side of the mixing tube provides the transition which
mounts the discharge from the combustion air fan into the burner. The bottom side of the mixing tube is attached to a stainless steel
perforated sleeve. This stainless steel sleeve is covered with a metal fiber alloy material that forms the burner port surface. The burner
port material is a metal fiber material which is a unique alloy of iron, chrome, aluminum and several rare earth metals. This alloy is
designed to operate stress free as a burner port surface. The burner port surface can sustain operation from a blue flame down to infrared
conditions as the burner input varies. Infrared operation will occur only as turndown is increased.
Model 500-2500: Direct ignition is standard. The burner mounting flange provides a flame view port and the mounting point for the Hot
Surface Igniter and the UV Scanner .
Model 3000-4000: Proven pilot ignition is standard. The burner mounting flange provides a flame view port, the mounting point for the
Hot Surface Igniter , a connection to the pilot tube and the UV Scanner .
The Hot Surface Igniter and UV Scanner are removable from the burner mounting flange without removing the burner assembly from the
heat exchanger.
Never use an open flame (match, lighter, etc.) to check gas connections, use a soap solution instead.
