3. Insert the fitting for a manometer or pressure gauge into the pressure tap hole.
4. Place the gas valve in the PILOT position and light the pilot. When the pilot lights and
continues to burn, increase the setting on the thermostat knob until the burner lights. Compare
the manometer or gauge reading to the appropriate table below.

LP
(2.49 kPa or 24.91 mbar)
5. If the burner manifold pressure does not meet the specifications in the tables in Step 4, unscrew
the slotted cap from the top of the gas valve regulator (adjacent to the gas valve vent tube) and
turn the adjusting screw to obtain the correct pressure. Turn the screw clockwise to increase
pressure, counter-clockwise to decrease pressure.
6. After adjusting the manifold pressure to the correct value, reinstall the regulator cap and turn the
gas valve knob to the OFF position.
7. Remove the manometer or pressure gauge fitting from the pressure tap hole and reinstall the pipe
plug.
8. Place the gas valve in the PILOT position and check for gas leaks. If no leaks are found, re-light
the pilot and return the unit to operation.
