To verify proper system installation, do the following:
1.
Make sure that there are no leaks in the gas lines and the air
lines.
2.
Make sure all the components of the flame monitoring control
system are properly installed. This includes verifying that all
switches are installed in correct locations and all wiring,
pressure and impulse lines are properly connected.
3.
Make sure components of spark ignition system are installed
and functioning properly.
4.
Make sure that the blower rotates in the correct direction. If
incorrect, then have a qualified electrician rewire the blower to
reverse its rotation.
5.
Make sure all valves are installed in proper location and
correctly oriented relative to the gas or air flow direction.
After installation of the burner system components is complete, the
following steps should be followed in order to prepare for
adjustment:
1.
Set the air pressure switch so that it drops out at 4" w.c. (10
mbar) below the pressure rating of the blower.
2.
Set the low gas pressure switch at 4" w.c. (10 mbar) below the
gas pressure measured at the inlet to the main gas valve train.
3.
Set the high gas pressure switch so that it comes on at 4" w.c.
(10 mbar) above the gas pressure measured at the inlet to the
main gas valve train.
4.
Close all the burner gas cocks.
5.
Try to light a burner before the purge and other timers have
finished their cycles. Make sure that the flame monitoring
system indicates a flame failure.
6.
Trip out pressure switches and other limit interlocks. Make
sure that the main gas valve train closes.
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.
