WARNING
If installing Boiler sizes 080 OR 180, do not attempt to convert 080 for use with LP at altitudes above 2000 ft
(610 m). Also, do not attempt to convert 180 for use with LP gas at altitudes above 7800 ft (2377 m). Attempts
to do so may result in unreliable operation, property damage, personal injury, or loss of life due to carbon
monoxide (CO) poisoning.
Instructions for High Altitude Installations Above 4500 FT.
These instructions apply only to altitudes from
4501 to 10200 ft. (1350 to 3109 m).
These instructions contain specific information to set up your Boiler to ensure proper operation.
WARNING
LP Conversions - Boiler setup from factory is configured for use with natural gas installed from 4501 to 10200
ft (1350 to 3109 m) above sea level only. For conversion to LP at altitudes from 4501 to 10200 ft (1350 to
3109 m), follow the “High Altitude Start-Up Instructions for LP” section in this supplement. This conversion
shall be performed by a qualified service agency in accordance with the manufacturer’s instructions and
all applicable codes and requirements of the authority having jurisdiction. If the information in these
instructions is not followed exactly, a fire, explosion, or production of carbon monoxide may result causing
property damage, personal injury, or loss of life. 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.
WARNING
Failure to set up Boiler in accordance with these instructions could result in production of high amounts of
Carbon Monoxide which could result in death, serious injury, and/or reduced component life.
WARNING
Asphyxiation Hazard. The outlet pressure for the gas valve has been factory set and requires no field
adjustment. This setting is satisfactory for both natural gas and LP. Attempting to adjust the outlet pressure
may result in damage to the gas valve and cause property damage, personal injury, or loss of life due to
carbon monoxide (CO) poisoning.
