6. Turn the gas on and place the thermostat at the
highest setting.
7. Adjust the screw in the regulator stack to the
desired reading on the manometer. (Turn
clockwise to increase the outlet pressure and
counterclockwise to reduce the outlet pressure.)
8. Reinstall the seal screw, which incorporates the
proper size hole for venting to the atmosphere. (It
may be necessary to cycle the valve several times
to verify the desired outlet pressure.)
9. Turn off the gas supply and place the thermostat
at the lowest setting.
10. Remove the pressure manometer and reinstall the
pressure tap plug.
11. Turn the gas on and set the thermostat at the
desired setting.
12. Check for leaks at the pressure tap plug with a
soap solution before leaving the site.
Pilot Gas Adjustment (Applications With a Pilot
Adjust)
Models with an optional manual pilot adjust allows
adjustment of the pilot gas flame. To adjust the pilot
gas flame:
1. Loosen the round head screw holding the small
adjustment plate beside the manual rotor pilot
valve knob, and turn the knob clockwise as far as
it goes.
2. Slowly push the adjustment plate in a
counterclockwise direction while watching the size
of the pilot burner flame.
3. Stop moving the adjustment plate when the pilot
flame reaches the proper size, and tighten the
round head screw. The rotor pilot valve provides
complete on/off operation with the adjustment
fixed at the On position.

Pilot Servicing
If pilot flame problems occur, check the following:
If the pilot flame burns yellow, it may be due to dirt
or lint covering the lower portion of the pilot
burner. Remove this using a soft brush or a
vacuum.
A flame approximately 1/2 in (12.7 mm) high must
surround the thermocouple tip (Figure 6).
Because this is an electrical connection, the
thermocouple lead connection to the BASO power
unit must be clean and free of grease.

!
CAUTION: Risk of Electric Shock.
Disconnect power supply before making electrical
connections to avoid electric shock.
!
WARNING: Risk of Explosion or Fire.
Shut off the gas supply at the main manual shutoff
valve before installing or servicing the G93. Failure
to shut off the gas supply can result in the release of
gas during installation or servicing, which can lead to
an explosion or fire, and may result in severe
personal injury or death.
