Step 3: Ignite the Burner

Low Fire Start
■ These procedures are written with the assumption
the burner has a flame monitoring control system
installed and operating. A proper purge cycle must
be part of the system and purge timing should not
be bypassed.

Figure 4.5. Low Fire Start
1. Drive control motor to low fire.
2. Be sure combustion air blower is running.
3. Open main gas manual shut off valves.
4. With pressure taps open, connect the manometer
between Tap E and the chamber.
5. Set system control to stay at low fire during and after
ignition sequence.
6. Attempt to ignite burner.
7. During trial for ignition, adjust bypass pressure
regulator  and adjustable limiting orifice  to achieve
the appropriate Δp between Tap E and the chamber as
listed in the appropriate datasheet.
NOTE: If viewing the flame, it should be blue with flashes
of yellow. The flame should be completely within the
combustion tube. When firing propane or butane, a proper
low fire flame may have sustained flashes of yellow.

8. If burner does not ignite.
a. Shut off gas.
b. When chamber temperature is below 250°F
(121°C), shut off combustion air blower.
c. Restart combustion air blower, drive through purge
cycle and ignite the burner.
d. Measure low fire gas pressure to the burner gas
inlet . Verify pressure at  is within the range
specified on the datasheet for your burner. range
specified on the datasheet for your burner.
10.After ignition, verify low fire flame:
a. Shut off gas.
b. When chamber temperature is below 250°F
(121°C), shut off combustion air blower.
c. Restart combustion air blower and ignite burner.
d. Measure low fire gas pressure to the burner gas
inlet .Verify pressure at  is within the range
specified on the datasheet for your burner.
e. Verify repeatability of ignition and low fire flame
signal.
NOTE: If the flame signal is too low, use the bypass

regulator and/or the adjustable limiting orifice
increase the pressure at Tap E and provide better flame
signal. However, this can have a negative impact on
emissions and/or nozzle life.
11. Close all pressure taps.
