WARNING
Do not operate, or allow others
to operate, service or repair this
equipment unless you (they) fully
understand all applicable sections
of this manual and are qualifi ed to
operate/maintain the equipment.
Check daily that the equipment area
is free and clear of any combustible
materials, including fl ammable
vapors and liquids.
 Ð
CAUTION
For all systems containing boilers or
unfi red steam generators, the water
chemistry in the boiler (generator) must
be kept within required limits. Failure
to do so may cause premature pressure
vessel failure and poor steam quality
and will void the warranty.
Perform Test of Low Gas Pressure Switch
Test the low gas pressure switch as follows:
1. With the boiler running turn down the low gas pressure switch until a lock
out is annunciated.
2. Reset the switch to normal level, re-start the boiler.
Perform Test of High Gas Pressure Switch
Test the high gas pressure switch as follows:
1. Close the downstream main gas cock and start the boiler.
2. Once the trial for ignition period is reached, the main gas valve will open,
pressurizing the line. This will trip the high gas pressure switch.
3. Manually reset the high gas pressure switch after it trips.
General Operation of the Boiler
Excessive cycling will reduce the useful life of any piece of mechanical
equipment. Vantage boilers should be operated and controlled so the boiler
cycles less than 12,000 times per year. Vantage boilers should be operated and
controlled so that the temperature diff erential across the boiler does not exceed
100°F (38°C).
