Adjustment, Start & Stop; Step 1: Reset The System - Honeywell Eclipse Winnox WX Series Installation Manual

Adjustment, Start &
Stop
In this chapter, you will find instructions on how to adjust,
start, and stop the burner system. Become familiar with
burner control methods before attempting to make
adjustments.
■ The Winnox burners are designed to mix fuel with
air and burn the resulting mixture. All fuel burning
devices are capable of producing fires and
explosions if improperly
adjusted, controlled, or maintained.
■ Do not bypass any safety feature; fire or explosion
could result.
■ Never try to light a burner if it shows signs of
damage or malfunction.

Step 1: Reset the System

1. Set the low gas pressure switch to 20% below the
"Fuel Inlet Pressure" range as specified in the
appropriate datasheet.
2. Set the high gas pressure switch to 20% above the
"Main Gas Inlet Pressure" range as specified in the
appropriate datasheet.
3. Close all the burner gas valves
automatic.
4. Try to ignite the burner; be sure the flame monitoring
system indicates a flame failure.
5. Activate the pressure switches and other limit
interlocks. Be sure the switches fail as intended in the
event of a power failure.

■ If simulated limits or simulated flame failure do not
shut down the fuel system within the required
failure response time, immediately correct the
problem before
"Troubleshooting" chart in section 5.
6. If the burner is firing into a duct or chamber with a
circulating fan, start the fan to produce full process air
flow past the burner.
7. Adjust main gas inlet pressure to the ratio regulator
within the range specified in the appropriate
datasheet.
■ Gas inlet pressures must stay within the specified
range. Pressure above the specified range can
damage the ratio regulator.
■ Pressure below the specified range can impair the
ability of the ratio regulator to control the gas flow.
■ Operating the system outside the specified range
can cause excess fuel consumption and the
possible accumulation of unburned fuel in the
chamber.
■ In extreme cases, this accumulation of unburned
fuel may cause fires or explosions.
8. Verify the actuator opens the air butterfly valve
towards the back of the burner as shown in Figure 4.1.
If it doesn't, refer to the actuator's literature for
instructions on how to reverse the direction.
