Perform Boiler Manual Start-up
Follow all instructions in the start-up section
for boiler start-up after converting for High
Altitude. Because the boiler has been changed,
you must verify correct operation, including
checking combustion with test instruments
both at high fire and low fire as described in
the this manual, pages 77, 78 & 79.
Check the correct ignition sequence of the
boiler after the conversion, as in page 86.
Failure to comply could result in severe per-
sonal injury, death or substantial property
damage.
