OPERATION
It is recommended that a qualified person perform the initial firing
of the heater. At this time the user should not hesitate to ask the
individual any questions which he may have in regard to the
operation and maintenance of the unit.
WARNING
THE GAS VALVE MUST HAVE BEEN IN THE OFF POSITION FOR
AT LEAST 5 MINUTES. This waiting period is an important safety
step. Its purpose is to permit gas that may have accumulated in
the combustion chamber to clear. IF YOU DETECT GAS ODOR AT
THE END OF THIS PERIOD DO NOT PROCEED WITH LIGHTING.
RECOGNIZE THAT GAS ODOR, EVEN IF IT SEEMS WEAK, MAY
INDICATE PRESENCE OF ACCUMULATED GAS SOMEPLACE IN
THE AREA WITH RISK OF FIRE OR EXPLOSION. SEE THE FRONT
PAGE FOR STEPS TO BE TAKEN.
Before lighting the pilot and operating the heater, the following
conditions must exist:
• Entire system filled with water.
• Air purged from all lines and no leaks (gas and water).
• All gas and water lines open.

OPERATE HEATER UNTIL ALL CORRECTIVE STEPS HAVE BEEN
MADE BY A QUALIFIED SERVICEMAN:

NEVER OPERATE THE HEATER WITHOUT FIRST BEING CERTAIN
IT IS FILLED WITH WATER AND AN A.G.A. TEMPERATURE AND
