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 54.
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.
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 CO
2
or O
2
and for CO during high ring rate.
With the front door on, the combustion readings
must be within the range listed in Table 4 on page
57. The CO level must not exceed 100 ppm for
natural gas and 150 ppm for propane gas when
combustion is correct. Perform the following pro-
cedure to manually place the burner into high re.
a. Press the round INSTALLER button. Reference
Section 9.1 on page 37.
b. Enter the installer access code “054” by using
the LEFT and RIGHT buttons to select a digit
and the UP and DOWN buttons to change the
digit. Press the OK button to enter the access
code.

then press the OK button.
d. Press the OK button while the FAN icon is high-
lighted to manually re the burner and power
the CH circulator(s).
DANGER
NOTICE
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. Press the RIGHT button to adjust the ring rate
from 1% to 100%. Hold down the RIGHT but-
ton to rapidly increase the ring rate.
f. Press the OK button while the FAN icon is high-
lighted to shutdown the burner.
3. If the combustion levels during high re (100%) are
outside the acceptable levels, adjust the THROTTLE
SCREW (see Fig. 14 on page 28) according to Ta-
ble 3 on page 57.
4. Once the combustion level is set at high re (100%),
manually place the boiler into low re (1%) mode
by pressing the LEFT button to adjust ring rate
down.
5. Verify the combustion levels during low re (1%) are
within the acceptable combustion levels in Table 4
on page 57.
If the combustion levels at low fire (1%) are
not within the range given in Table 4 on page
57, 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.
