Operation
3.2.1 — Gas Fired
1. Close the pilot and the main line manual gas valves.
2. Start the burner and at the time of the pilot trial, with just the electrical ignition system energized, the flame relay
should not pull in (be energized).
3. Upon completion of successful test, proceed with startup procedures.
3.2.2 — Oil Fired
1. Disconnect the electrical power to the burner.
2. Disconnect the electric oil safety shutoff valve.
3. Reconnect electric power to the burner.
4. Close the pilot line manual gas valve, if used.
5. Start the burner and at the time of the pilot trial, with just the electrical system energized, the flame relay should not
pull in.
6. Upon completion of successful test, disconnect the power supply,
7. Reconnect oil safety shutoff valve and turn on manual pilot gas valve.
8. Reconnect power supply and proceed with startup procedures.
3.3 — Gas Pilot Flame Adjustment
The gas pilot flame is regulated by adjusting the pressure setting of the pilot regulator. Normal setting is 3" to 6" W.C.
when the pilot is burning. The flame must be sufficient to be proven by the flame detector and ignite the main flame.
Although it is possible to visibly adjust the size of the pilot flame, obtain a proper DC volt or microamp reading of the
flame signal.
The flame safeguard amplifier has a meter jack for this purpose. At initial startup and during planned maintenance, test
the pilot flame signal, pilot turndown, and safety switch lockout.
3.4 — Startup Sequence
The programming control sequences the operation of all controls and components through the starting, ignition, firing,
and shutdown cycle. The burner and control system are in starting condition when:
• The operating and high limit control (temperature or pressure) are below their cutoff setting.
• All power supply switches are closed.
• Power is present at the control panel.
Refer to the manufacturer’s literature on programming controls and burner wiring diagrams for detailed information.
1. Begin starting sequence, with burner switch off, and with all manual valves closed. Switch main power on.
2. When firing oil, open the manual oil valves.
3. When firing on gas, open the main manual gas valve.
4. When firing on gas, manually reset the high and low gas pressure switches.
