1. Start the combustion air fan.

2. Set the air control damper to produce the desired pressure

drop across the burner.  Air pressure drop should be read as a
differential pressure between the windbox pressure test port
and the chamber. See the combustion air pressure drop versus
air flow curves (Tables A.1 and A.2 in the Appendix).

Make sure that all the settings are still the same after you cycle the
system several times between high fire and low fire. Check air
proving switch and adjust if necessary.

Note:
Test spark ignitor with a visual or audible check before
attempting ignition.

1. Set system to operate on pilot only. See the literature included

with the flame monitoring relay.

2. Set pilot regulator to 6"w.c. outlet pressure.

3. Open the pilot adjusting valve two turns.

4. Initiate start sequence and ignite the pilot.

Note:
Initially it may be necessary to repeat step 4 two or three times
to purge air out of the gas pipework.

5. Trim pilot with adjustable gas cock to obtain pressure drops of:

• 1.5" to 2.0"w.c. for natural gas

• 0.6" to 0.9"w.c. for propane, butane

Refer to Table 4.1 at left for pilot input capacities. Pressure drop
is differential between pilot gun inlet and chamber.

Note:
The pilot flame should be a bushy, blue flame which curls
around the main gas/oil gun nozzle. This flame should provide a
stable pilot with good flame signal readings sufficient to
energize the main gas valve.

6. If necessary, adjust the position of the U.V. scanner to ensure

good pilot flame detection.
