Sta-Rite Air Orifice Kit for Model 200 Max-E-Therm Heater, 77707-0111

This is the 77707-0111 air orifice kit for the model 200 Max-E-Therm pool heater. It is a burner system part, supplied as a kit.

What it does

The air orifice meters the air side of the burner. Gas heaters fire cleanly only when air and fuel arrive in the right proportion, so an orifice that is damaged, blocked or simply the wrong size for the heater shows up as rough ignition, poor flame or soot in the burner tray.

Before you order

Match the heater size. This kit is listed for the model 200, and the larger Max-E-Therm heaters use their own parts, so confirm the size on the data plate before ordering.
