5.
Activate the pressure switches and other limit interlocks.
Be sure the switches fail as intended in the event of a
power failure.
Danger:
If simulated limits or simulated flame failures
do not shut down the fuel system within the
required failure response time, immediately
correct the problem before proceeding.
6.
If the burner is firing into a duct or chamber with a
circulating fan, start the fan to produce a full process air
flow past the burner.
7.
Adjust main gas inlet pressure to the ratio regulator within
the range specified in the appropriate data sheet.
Warning:
Gas inlet pressures must stay within the
specified range. Pressure above the specified
range can damage the ratio regulator.
Warning:
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 that the actuator opens the air BV towards the back
of the burner as shown. If it doesn’t, refer to the actuator’s
literature for instructions on how to reverse the direction.
