boiler to LP gas without using a combustion
analyzer to verify CO does not exceed 200
ppm air free for altitudes 0 to 2,000 ft. (0 to
610 m) and 300 ppm air free for altitudes
above 2,000 ft. (610 m). (In event of high
CO, consult section 19 Troubleshooting).

Failure to properly convert this boiler
for use on LP gas could cause unreliable
operation at elevated carbon monoxide
(CO) levels, resulting in severe personal
injury, death or substantial property damage.
