Operation
CAUTION
During startup insure that adequate gas
pressure is supplied to the main valves.
The indicator on the actuator should
never reach the bottom of the indicator
window. In the event that this happens,
adjustability will be lost. See minimum
incoming gas pressure requirement on
the test fire sheet. The SKP10 actuator
functions only as
activated, the indicator will reach the
bottom of the indication window. The
main gas pressure regulator is only
used to comply with
regulations and therefore uses a high
outlet pressure spring that is set at the
max. The SKP70 fuel valves have a built
in regulator function.

IMPORTANT
When commissioning this boiler, firing rate
must remain at low fire during first
4 hours of operation. The output may then
be increased 7% to 10% per hour, until a
firing rate of 75% is reached. The 75% firing
rate should be maintained for 3 to 4 hours.
