Honeywell Gas Control Testing, Disassembly, and Replacement

The Gas Control is made up of (5) major components; the control cover, the piezo igniter, the valve body, the temperature
sensor, and the back plate. The Gas Control is designed so that any of these components may be replaced without
replacing the entire Gas Control.

LINE PRESSURE

The Gas Control is designed for a maximum line pressure of 14.0" w.c. and a minimum line pressure of 1.0" w.c. over the
water heater’s rated manifold pressure (check rating plate). Line pressure must be checked with the main burner on and
off to assure proper readings.
