Appendix A - Instructions for High Altitude Installations Above 2000 ft.
These instructions apply only to the following Phantom X boiler configurations: 2001 ft- 4500 ft, 4501 ft- 6000 ft,
6001 ft- 7800 ft, 7801 ft - 10,000 ft.
These instructions contain specific instructions to properly set up your boiler to ensure proper
operation.
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 air free) 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.
WARNING
Failure to set up 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 PHNTM500C: Do not convert PHNTM500C to LP gas (propane) at altitudes above 6000 ft.
Attempts to do so may result in unreliable operation, property damage, personal injury or loss of life due to
carbon monoxide (CO air free) poisoning.
WARNING
LP Conversions - Phantom X boiler setup from factory is configured for use with natural gas installed from
0 - 2000 ft above sea level only. For PHNTM399C or PHNTM500C conversion to LP at altitude above 2000
ft, follow these instructions as specific instructions must be followed when 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.
