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
!
WARNING: Risk of Explosion or Fire.
Shut off the gas supply at the main manual shutoff
valve before installing or servicing the H15. 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.
Field repairs must not be made to the H15 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.
