P/N 100128 WITH STEMCO THERMOSTAT

P/N 109069

For all Navy machines that are purchased with steam heated boosters. This notification is
for the replacement of the thermostat in those boosters. To ensure that the thermostat is
placed properly into the booster tank, please follow the diagram listed below. When replac-
ing the the thermostat use part number 109069.

1. Mark off the measurement of 12 inches from the end of the bulb. This will be at the end
of the 1/2" nut that mounts inside of the tee.
2. Insert the thermostat bulb 12 inches into the booster. Ensure that the bulb is inside one
of the copper water tubes and not coiled up inside of the head. Place plumbers putty on
