ADJUSTMENTS
Check gas supply pressure to the appliance using a manometer connected to the inlet pressure tap.
Start boiler. To prevent the burner from modulating use the domestic hot water demand or a large volume central heat
zone.
Check gas supply pressure to the appliance a second time using a manometer connected to the inlet pressure tap.
Using combustion test equipment, insert the probe into the exhaust gas outlet (flue port)
Fuel Adjustment Procedure

–
13”w.c.
Set max outdoor temp: INFO buttonQuick StartMax Outdoor Temp
Set min outdoor temp: INFO buttonQuick StartMin Outdoor Temp
If the INFO Test screen displays two
options (Forced Rate, Manual Pump
Operation), use Method 1 on the following
page.
If the INFO Test screen displays three
options (Forced Rate, Manual Burner
Operation, Manual Pump Operation), use
Method 2 on the following page. NOTE: Do
not use the “Manual Burner Operation”

Fuel Adjustment Method 1
1. Start appliance
2. Run appliance at maximum fan speed (See Table in Boiler manual for specific model): INFO buttonAdvanced
SetupModulation Config. Use left and right arrows only. To delete prior setting, arrow to DEL and press OK
repeatedly until cleared, then use arrows to enter maximum RPM.
3. Check that O2 reading is 4.5% and adjust throttle screw if necessary. Turn throttle screw clockwise to increase
O2 and counter clockwise to decrease O2.
4. Keep appliance running until completely stabilized, make adjustment when necessary.
Offset adjustment
5. Set appliance to minimum fan speed (See Table in Boiler manual for specific model): INFO buttonAdvanced
SetupModulation Config. Use left and right arrows only. To delete prior setting arrow to DEL and press OK
repeatedly until cleared, then use arrows to enter minimum RPM.
6. Remove cap screw with a Torx T-40 screw driver or 5 mm hex key to expose offset adjustment screw
7. Check that offset O2 reading is 4.5% and adjust if necessary. Turn counter clockwise to increase O2 and
clockwise to decrease O2 reading. Adjust in very small increments, and allow to stabilize between adjustments.
8. Reset appliance fan speed to maximum RPM (see Item 2 above). Verify speed is at max RPM. To view current
fan speed, press “Home”.
9. Perform carbon monoxide test two minutes after light off. If the carbon monoxide exceeds 400 ppm air-free after
two minutes of operation, shut off boiler immediately and repeat "Prepare for Start Up" checklist found in
installation manual.
Repeat steps 1 to 6 when adjustment of offset pressure is necessary, resetting fan speed to maximum.
Fuel Adjustment Method 2
1. Start appliance
2. NOTE: Do not use the “Manual Burner Operation” menu. Using this feature may result in unintended and
undesired behavior.
3. Set appliance maximum and minimum fan speed (See Table in Boiler manual for specific model): INFO
buttonAdvanced SetupModulation Config. Use left and right arrows only. To delete prior setting, arrow to
DEL and press OK repeatedly until cleared, then use arrows to enter RPMs.
4. Navigate to test mode menu: INFO Test Forced Rate. Select “Set Low Fire”, wait (2) seconds to be sure
“Manual firing rate” displays the desired fan speed. Repeat with “Set High Fire”. Select “Start Test”.
5. Check that O2 reading is 4.5% and adjust throttle screw if necessary. Turn throttle screw clockwise to increase
O2 and counter clockwise to decrease O2.
6. Keep appliance running until completely stabilized, make adjustment when necessary.
Offset adjustment
7. Set appliance to minimum fire by selecting “Set Low Rate”.
8. Remove cap screw with a Torx T-40 screw driver or 5 mm hex key to expose offset adjustment screw
9. Check that offset O2 reading is 4.5% and adjust if necessary. Turn counter clockwise to increase O2 and
clockwise to decrease O2 reading. Adjust in very small increments, and allow to stabilize between adjustments.
10. Reset appliance fan speed to max RPMs (see Item 2 above). Verify “Manual firing rate” displays correct RPM.
11. Perform carbon monoxide test two minutes after light off. If the carbon monoxide exceeds 400 ppm air-free after
two minutes of operation, shut off boiler immediately and repeat "Prepare for Start Up" checklist found in
installation manual.
Repeat from 1 to 6 inclusive when adjustment of offset pressure was necessary, resetting maximum fire to 6000
RPM, or 5000 RPM for an EK2C.
NOTE: Setting the fan speed outside the recommended range may cause a lockout.
After adjustments are made, stop appliance, disconnect pressure gauge and combustion analyzer. Make sure to tighten
inlet pressure tap, offset cap screw and combustion test port.
Final checkout of the installation
Refer to Installation and Service Manual for final checkout. After any adjustment, set appliance in operation. Observe
several complete cycles to ensure that all burner components function correctly.
