CALIBRATION MODE:
Proceed as follows to enter “calibration mode” on the boiler control panel and calibrate
the gas value:
1. Turn the control knobs 6 and (fig. 1 7 fully counter-clockwise to their
minimum positions as shown below.
2. Starting in this position, quickly turn control knob 7 twice, consecutively,
clockwise approximately a ﾼ turn as shown below in fig. 2.
Note: LED’s 2 and 3 (fig. 4) f ash a ternate y and the disp ay a ternates the message
“SF” and the boi er output temperature every five seconds (fig. 3).
3. Now turn knob 6 to adjust the fan speed to a setting between minimum
thermal power (0% and maximum thermal power (100% .
Note: In “ca ibration mode”, the disp ay a ternates between the message “P” and
the boi er output temperature about every 5 seconds. (fig. 4)
4. Calibration mode remains active for 20 minutes. To exit “calibration mode”
before this time simply turn control knob 7 twice, consecutively, clockwise
approximately a ﾼ turn as shown in fig. 2.
Note: This function is interrupted if the centra heating de ivery temperature
reaches its MAX. SETPOINT.
PROCEED AS FOLLOWS TO CALIBRATE THE GAS VALVE:
1. Ensure your combustion analyzer is set to NG, insert the flue probe into the flue
opening on the top of the boiler, after removing the two flue test port plugs.
2. Calibrate maximum thermal power by turning knob 6 clockwise to max. With the
boiler operating at max. output, check the value for CO2 measured in the flue is
8.7%. If necessary, turn the adjustment screw, or “V” screw, on the gas valve.
Turn c ockwise to reduce the CO2 eve or counter-c ockwise to increase it.
3. Calibrate minimum thermal power. With boiler operating at minimum output by
turning knob 6 counter-clockwise to minimum setting. Check the CO2 value
measured in the flue to 8.4% CO2. If necessary adjust the “K” screw (4mm hex on
the gas valve. Turn c ockwise to increase the CO2 eve or counter-c ockwise
to reduce it.
Note: A ow time between adjustments for your combustion ana yzer to sense the adjusted for your
combustion ana yzer to sense the adjusted CO2 eve . The boi er is now ready for norma operation using NG
gas and can be returned to the service mode by turning contro knob 7.

The following must be performed before calibrating the gas valve.
1. Turn the adjusting screw, or “V” screw (2. mm hex) on the gas valve all the way clockwise until the
“V” is bottomed out. Then turn the “V” screw eleven complete revolutions counter clockwise.
2. On the QAA73 controller, which is connected to terminals 4 & on the M2 bus terminal, set
parameters 608 to 24% and parameter 611 to 2000 rpm.
