WARNING
LP Conversions - boiler setup from factory is congured for use with natural gas installed from 0 - 2,000
ft. above sea level only. For conversion to LP, use a proper conversion kit per Table 3.1. Use combustion
analyzer and follow all instructions supplied with conversion kit. If the instructions are not followed exactly,
a re, an explosion or production of carbon monoxide may result causing property damage, personal injury
or loss of life. The qualied service agency is responsible for proper installation of this boiler for use with
LP gas. The installation is not proper and complete until he operation of the converted appliance is checked
as specied in the manufacturer's instructions supplied.
These instructions include a procedure for adjusting the air-fuel mixture on this boiler. This procedure
requires a combustion analyzer to measure the CO
2
(or Oxygen) and Carbon Monoxide (CO) levels in ue
gas. Adjusting the air-fuel mixture without a proper combustion analyzer could result in unreliable boiler
operation, personal injury, or death due to carbon monoxide poisoning.
Failure to setup the boiler in accordance with these instructions could result in high amount of Carbon
Monoxide to be produced which could result in death, serious injury, and/or reduced component life.
