6. After the burner lights, force the burner to high fire
by simultaneously pressing and holding the "Mode"
button and "+" button. After a few seconds, the
display should flash "H", indicating that the boiler
has been driven to high fire. Allow the boiler to
operate for approximately 5 minutes before taking
combustion readings. Note: after 15 minutes, the
boiler is automatically released from high fire hold.
Be sure to restore high fire hold if additional time is
needed to obtain high fire combustion readings.
The pressure regulator has been factory set using precision instruments and must never be adjusted in
the field. The gas valve outlet pressure is the same for both natural gas and propane. Make sure that
all adjustments are made with the throttle, not the pressure regulator. attempting to adjust the pressure
regulator will result in damage to the gas valve and may cause property damage, personal injury or loss of
life.

7. Perform a combustion test. Boilers equipped with a
concentric vent system have a flue gas sample tap
located in the boiler vent collar (under the screw
cap).
8. While the burner is at high fire adjust the throttle as
needed to obtain the CO
the Table 23:
• To reduce the CO
throttle clockwise
• To increase the CO
throttle counter-clockwise
Make adjustments in increments of 1/8 to 1/4 turn
and allow the boiler at least a minute to respond to
each adjustment before making another. In general,
the CO level will be at its lowest somewhere in the
CO
range shown in this table.

9. Verify that the gas inlet pressure is between the
upper and lower limits shown in Table 24 with all
gas appliances (including the converted boiler) both
on and off:
10. A label sheet is provided with the boiler for
conversions from natural to LP gas. Once conversion
is completed, apply labels as follows:
• Apply the "Rating Plate Label" adjacent to the
rating plate.
• Apply the "Gas Valve Label" to a conspicuous
area on the gas valve.
