2. Using a 3/8” FNPT barb fitting and hose, connect a 0-30” manometers (or
similar pressure indicating device) to the pressure tap port at the bottom of
the drip leg and at the pressure port at the inlet to the burner. You will have
to remove the 3/8” plugs and drain the drip leg first.
3. Open the supply valve to the Thermostat Supply Regulator.

dial to "RUN" (“PILOT on previous version) position. Push down the "PILOT"
button while igniting pilot (hold button down for 30 - 60 seconds). After pilot
flame is established, rotate the temperature control dial counter-clockwise

5. With the main burner operating, adjust the Thermostat Supply Regulator to
obtain burner pressure (at the burner pressure port) as indicated on page 3.
To adjust the Thermostat Supply Regulator pressure, remove the cap (See
Figure 12) and turn the adjustment screw with a standard screwdriver
clockwise to increase and counter-clockwise to decrease the pressure.
Return Thermostat Supply Regulator cap when complete.
6. Close the supply valve to the Thermostat Supply Regulator and
wait until
the pilot and main burner have extinguished
. Turn the gas control dial to
“OFF" position. Remove the manometer and fittings.
