11.3.4 Verify Flame Pattern and Combustion
1. Check the ame pattern through the observation
port of the heat exchanger. The ame should be
blue and stable. The ame should be over the length
of the burner head. It is not possible to determine
correct combustion by inspecting the colour and
pattern of the ame. It is important to measure
combustion with a calibrated ue gas analyser.
Combustion testing and adjustments must
be performed by a qualified installer, service
agency or the gas supplier. All combustion
measurements must be performed with
recently calibrated equipment (1 year max.) to
ensure proper reading and accuracy.
2. Test for CO2 or O2 and for CO during high ring rate.
The combustion readings must be within the range
listed in Table 6 on page 74. The CO level must not
exceed 150 ppm for natural gas or 200 ppm for
propane gas. Perform the following procedure to
manually place the burner into high re.
a. Touch simultaneously on the and soft
keys for 3 seconds to access the functions for the
installer. Reference Section 9.1 on page 51.
b. Enter the installer access code “054” by using
the
and soft keys to select a digit location
and the and soft keys to change the digit.
Touch the soft key to enter the access code.
c. Touch the soft key to highlight the Manual

then touch the soft key.
d. Touch the soft key while the FAN icon is
highlighted to manually re the burner and
power the CH circulator(s).
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.
e. Touch the soft key to adjust the ring rate
from 1% to 100%. Hold down the soft key to
rapidly increase the ring rate.
f. Touch the soft key while the FAN icon is
highlighted to shutdown the burner.
3. If the combustion levels during high re (100%) are
outside the acceptable levels, adjust the THROTTLE
SCREW (see Fig. 35 on page 73) according to
Table 6 on page 74.
4. Once the combustion level is set at high re (100%),
manually place the boiler into low re (1%) mode by
touching the
soft key to adjust ring rate down.
5. Verify the combustion levels during low re (1%) are
within the acceptable combustion levels in Table 6
on page 74.
If the combustion levels at low fire (1%) are
not within the range given in Table 6 on page
74, shut the boiler down and contact Ideal
Technical Support. Failure to comply with
this requirement can result in substantial
property damage, serious injury, or death.
