Appendix A: Instructions for High Altitude Installations Above 2000 ft.
WARNING
If installing K2WT-080B or K2WT-180B, do not attempt to convert K2WT-080B for use with
LP at altitudes above 2000 ft. Also, do not attempt to install K2WT-180B at altitudes above 2000ft. K2WT-
180M shall be installed at altitudes ranging from 2001-10100ft. Attempts to do so may result in unreliable
operation, property damage, personal injury or loss of life due to carbon monoxide (CO) poisoning.
These instructions apply only to the following K2WT boiler configurations: 2001 ft.- 6000 ft, 6000 ft.- 7800 ft., 7801
ft.- 10,100 ft.
These instructions contain specific information to setup your boiler to ensure proper operation.
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 any conversion to LP, use a proper conversion kit
per Table 3.1. Use a combustion analyzer and follow all instructions supplied with conversion kit. If the
instructions are 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.
•
These instructions include a procedure for adjusting the air-fuel mixture on this boiler. This procedure
requires a combustion analyzer to measure the CO
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.
