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 B Valve)
Models with an optional manual rotor pilot valve
(B valve) allow 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 4).
• Because this is an electrical connection, the
thermocouple lead connection to the BASO power
unit must be clean and free of grease.

Repairs and Replacement
!
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.
!
WARNING: Risk of Explosion, Fire, or
Electric Shock. Label all wires before they are
disconnected when replacing or servicing the G93.
Wiring errors can cause improper or dangerous
operation and may result in an explosion, fire, or
electric shock leading to severe personal injury or
death.
Field repairs must not be made to the G93 valve. If
the thermocouple meets the output listed in Table 1
and the valve does not function, replace the entire
valve. Any attempt to repair this assembly voids the
manufacturer’s warranty. For a replacement valve,
contact the original equipment manufacturer or the
nearest BASO Gas Products distributor.
