Operation
temperature, humidity, barometric pressure), and fuel property changes. Refer to the nameplate inside the control panel
for minimum and maximum fuel input ratings.
3.1.4 — Test Equipment
The following tests should be conducted on site:
1.
Combustion analyzer with O
2
indication
2.
U-Tube manometer, or pressure gauge, to measure gas pressures (Main)
3.
Inclined manometer to measure draft pressures
4.
CO analyzer
5.
Voltmeter/Ammeter
6.
Stack thermometer and thermocouple
3.2 — Ignition Adjustment
The ignition flame is regulated by adjusting either the main butterfly valve or the ratio regulator. Normal setting is 0.5"
W.C. when the burner is on. The flame must be sufficient to be proven by the flame detector and ignite the main flame.
Although it is possible to visibly adjust the size of the minimum flame, obtain a proper DC volt or microamp reading of
the flame signal. Refer to Flame Safeguard manufacturers instructions for optimal flame signal readings.
Some flame safeguard amplifier or flame safeguard chassis body has a meter jack for this purpose. At initial startup and
during planned maintenance, test the flame signal, burner turndown, and safety switch lockout.
3.3 — Startup Sequence
The programming control sequences the operation of all controls and components through the starting, ignition, firing,
and shutdown cycle. The burner and control system are in starting condition when:
•
The operating and high limit control (temperature or pressure) are below their cutoff setting.
•
All power supply switches are closed.
•
Power is present at the control panel.
Should a starting failure occur for any reason, combustible fumes may fill the combustion chamber. Never attempt to re-
light the burner under these conditions without first purging the chamber.
Read the flame safeguard manual and fully understand its content before attempting to operate this equipment. If this
instruction is ignored, serious injury or death may result.
