Step 3: Install the Flame Monitoring System
Refer to the System Schematic in Design Guide 310 for
the control methodology used. A detailed explanation of
components can be found in the appendix.

Checklist After Installation

To verify proper system installation, do the following:
1. Ensure that there are no leaks in the gas lines and the
air lines.
2. Ensure 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. Ensure components of spark ignition system are
installed and functioning properly.
4. Ensure that the blower rotates in the correct direction.
If incorrect, then have a qualified electrician rewire the
blower to reverse its rotation.
5. Ensure all valves are installed in proper location and
correctly oriented relative to the gas or air flow.

Prepare for Adjustment

After installation of the burner system components are
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 or pressure taps.

5. Try to light a burner before the purge and other timers
have finished their cycle. 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.
■ 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.
