1) If not already done, install the boiler in accordance
with this manual, following all instructions in
Section XI “Start-up and Check-out” up to Step 10.
2) Install provided LP gas orifice per Table A. Orifice
installation is shown in Figure A.1. Boiler sizes
205 and 270 require field installation of factory

DANGER
These instructions include a procedure for adjusting the air-fuel mixture on this boiler. This procedure
requires a combustion analyzer to measure the CO2 (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
This conversion kit shall be installed 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, 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 kit. The installation is not proper and complete until the
operation of the converted appliance is checked as specified in the manufacturer’s instructions supplied
