WARNING
!
Failure to perform a complete combustion test at both
high and low input rates may result in incomplete
combustion and the production of carbon monoxide,
which can cause severe personal injury, death or sub-
stantial property damage.

keys (as high lighted by the wrench icon) for 3 sec-
onds to access the functions for the installer. See

Operation icon then press the OK button.
4. Press the center button while the FAN icon is high-
lighted to manually fire the burner and power the
CH circulator. See Fig. 14
NOTICE
An adequate CH load must be present to dissipate the heat
generated during the combustion test. If an adequate CH
load is not available, an indirect water heater can be used to
dissipate the heat by creating a DHW call which will enable
the DHW circulator.
5. Press the RIGHT button to adjust the firing rate to
100% (high fire). Hold down the RIGHT button to
rapidly increase the firing rate.
6. If the combustion levels during high fire are outside
the recommended combustion settings, adjust the
THROTTLE SCREW using a flat-blade screwdriver as
follows:
Counter-clockwise adjustment of the THROTTLE
SCREW at High Fire (100% firing rate):
Increase CO2 & Decrease O2
Clockwise adjustment of the THROTTLE SCREW at
High Fire (100% firing rate):
Decrease CO2 & Increase O2
7. Once the combustion level is set at high fire, manu-
ally place the boiler into low fire mode by pressing
the LEFT button to adjust firing rate down to 0%
(low fire).
8. If the combustion level (O2 or CO2) during low fire
is not /-0.2 of the combustion level mea-
sured at high fire, shut down the boiler and contact
