Perform Boiler Manual start-up
Follow all instructions in the start-up section for boiler start-up after convert-
ing for High Altitude. Because the boiler has been changed, you must verify cor-
rect operation, including checking combustion with test instruments both
at high fire and low fire as described in the Boiler Manual, pages 76, 77 & 78.
Check the correct ignition sequence of the boiler after the conversion, as in page 86.
Failure to comply could result in severe personal injury, death or substantial property damage.
