4. Combustion Test and Adjustments
NOTICE
The installer MUST perform a complete combustion check
to ensure the following combustion levels are met at high
and low input ring rates and the burner is operating at op-
timum conditions.
WARNING
!
The combustion testing and adjustments must be per-
formed by a qualified installer, service agency or the
gas supplier. All combustion measurements must be
performed with calibrated equipment to ensure prop-
er readings and accuracy.
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.

NOTICE
An adequate CH load must be present to dissipate the heat

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.

using a at-blade screwdriver as follows:
Counter-clockwise adjustment of the THROTTLE

ally place the boiler into low re mode by pressing
the LEFT button to adjust ring rate down to 1%
