Warning
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.
Warning
If installing K2WT-080 or K2WT-180, do not attempt to convert K2WT-080 for use with LP at altitudes above
2000 ft. Also, do not attempt to convert K2WT-180 for use with LP gas at altitudes above 7800 ft. Attempts
to do so may result in unreliable operation, property damage, personal injury or loss of life due to carbon
monoxide (CO) poisoning.
Warning
LP Conversions - K2WT boiler setup from factory is configured for use with natural gas installed from 0 -
2000 ft above sea level only. For conversion to LP at altitude above 2000 ft., please follow these specific
instructions before converting for use with LP. If the information in these instructions is not followed
exactly, a fire, an explosion or production of carbon monoxide may result causing property damage,
personal injury or loss of life. The qualified service agency is responsible for proper installation of this
boiler for use with LP gas. The installation is not proper and complete until the operation of the converted
appliance is checked as specified in the manufacturer’s instructions supplied.

DangEr
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 flue
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.
