e. Press the LEFT and RIGHT buttons to
adjust the firing rate from 1% 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 ACV-Triangle
Tube Technical Support. Failure to com-
ply with this requirement could result in
severe personal injury, death or substan-
tial property damage.
If the combustion levels during HIGH
FIRE (100%) is outside the recommended
combustion settings adjust the THROT-
TLE SCREW (see Fig. 13 on page 27)
according to Table 5.
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 CO2 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
Figs. 13 on page 27) according to Table 6.
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 58.
2. Operate the unit for approximately 10
minutes.
3. Turn off all gas appliances within the build-
ing, except the PRESTIGE Excellence.
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.
