CHAPTER 11 - START-UP PROCEDURES
11.3.4 Check Gas Piping
Check around the unit for gas odor following the proce-
dure outlined in this manual on page 64.
If any gas leaks are found or suspected, shut
the unit down immediately. Use a gas de-
tection device or bubble test to locate the
source of the gas leak and repair at once. Do
not operate the unit until the leak is correct-
ed. Failure to comply with this procedure will
result in substantial property damage, seri-
ous injury, or death.
11.3.5 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 de-
termine correct combustion by inpecting eh 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 agen-
cy or the gas supplier. All combustion mea-
surements 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 and
200 ppm for propane gas when combustion is
correct. Perform the following procedure to manu-
ally 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.
DANGER
NOTICE
d. Touch the soft key while the FAN icon is
highlighted to manually re the burner and
power the CH circulator(s).
An adequate CH load must be present to dissi-
pate 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 en-
able 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. 13 on page 25 and Fig. 27 on
page 43, and Fig. 28 on page 44) according to
Table 5 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 Trian-
gle Tube Technical Support. Failure to com-
ply with this requirement can result in sub-
stantial property damage, serious injury, or
death.
