Start-Up Procedures
c
Check Gas Piping
Check around the appliance for gas
odor following the procedure outlined
in this manual on Page 34.
If any gas leaks are found or suspected,
shut the appliance down immediately.
Use a gas detection device or bubble test
to locate the source of the gas leak and
repair at once. Do not operate the appli-
ance until the leak is corrected. Failure
to comply with this procedure could
result in severe personal injury, death or
substantial property damage.
c
Verify Flame Pattern and Combustion
Check the flame pattern through the
inspection port of the burner.
The
flame should be stable and the full
length of the burner head openings.
The combustion testing and adjustments
must be performed by a qualified
installer, service agency or the gas suppli-
er. All combustion measurements must be
performed with calibrated equipment to
ensure proper reading and accuracy.
Test for CO2 or O2 and for CO during
high and low firing rates. To manually
place the appliance into high or low fire
mode, reference page 40, the combus-
tion reading should be within the range
listed in Table 3.
The CO level should
not exceed 100 ppm when combus-
tion is correct.
The combustion levels should be mea-
sured at high and low firing rates, refer
to page 40 on how to set the firing rates.
If the combustion levels are not within
the range given in Table 3 for the firing
rate, shut the appliance down and con-
tact Triangle Tube’s Engineering
Department. Failure to comply with this
requirement could result in severe per-
sonal injury, death or substantial prop-
erty damage.
c
Measure Input - Natural Gas Only
1. Ensure the appliance is firing at maximum
firing rate. To manually place the appliance
into high fire mode, reference page 40.
2. Operate the appliance for approximately
10 minutes.
3. Turn off all gas appliances within the build-
ing, except the MODULATING DELTA.
4. At the gas meter, record the time required
to use one cubic foot of gas.
5. Calculate Natural gas input using the fol-
lowing equation:
3600 x 1000 / number of second recorded
for one cubic foot of gas = BTU/H.
6. The BTU/H calculated should approximate
the input rating listed on the appliance.
