Start-Up Procedures
e. Press the LEFT and RIGHT buttons to
adjust the firing rate from 0% to 100%.
Hold down the LEFT or RIGHT but-
ton to rapidly increase or decrease the
firing rate.
f. Press the OK button while the FAN icon
is highlighted to shutdown the burner.
g. Cycle power to the Prestige once com-
bustion testing is complete to return to
normal operation.
The combustion levels should be mea-
sured at high firing rate. If the combus-
tion levels are not within the range given
in Table 4 for the firing rate, shut the
boiler down and contact Triangle Tube
Engineering Department. Failure to
comply with this requirement could
result in severe personal injury, death or
substantial property damage.
If the combustion levels during high fire
(100%) is outside the recommended combus-
tion settings adjust the THROTTLE SCREW
(see Fig. 16 & Fig. 17 page 29) as follows:
Counter-clockwise adjustment of the throt-
tle screw at High Fire:
O
2
decreases and CO
2
increases
Clockwise adjustment of the throttle screw
at High Fire:
O
2
increases and CO
2
decreases
3. Once the combustion level is set at high fire
(100%), manually place the boiler into low
fire (1%) mode by pressing the LEFT but-
ton to adjust firing rate down.
4. If the CO
2
combustion level during low
fire (1%) is not within +/- 0.2 of the com-
bustion level measured at high fire, adjust
the plastic OFFSET SCREW under the
cover screw on the top of the gas valve (see
Fig. 16 & Fig. 17 page 29).
Counter-clockwise adjustment of the OFF-
SET SCREW at Low Fire:
O
2
increases and CO
2
decreases
Clockwise adjustment of the OFFSET
SCREW at Low Fire:
O
2
decreases and CO
2
increases
c Measure Input - Natural Gas Only
1. Ensure the boiler is firing at maximum firing
rate. To manually place the boiler into high
fire mode, reference page 60.
2. Operate the unit for approximately 10
minutes.
3. Turn off all gas appliances within the build-
ing, except the PRESTIGE Solo.
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 unit.
