WARNING
All information in this manual is for
reference and guidance purposes,
and does not substitute for required
professional training, conduct,
and strict adherence to applicable
jurisdictional/professional codes and
regulations.
Non-Fulton product information is for
reference purposes only. No Fulton
document may substitute for full
review of documentation available
from the component manufacturer.
6. Safety lock out occurs within a preset minimum time in the event of
insuffi cient, unstable or non-existent fl ame. After fault has been corrected,
reset programmer by depressing the reset button on the casing of the
burner control box.
7. Proper fuel pressure at the burner nozzle is essential. The correct fi ring rate
is obtained by setting the fuel oil pump to give the design pressure for
each unit. This is done at the factory. Pressure is measured by connecting
a 0-400 PSI (0-25 bar) test pressure gauge to the gauge connection on the
fuel pump. The fuel pressure gauge indicates the pressure of the fuel at the
burner nozzle.
8. Typical pressures range between 160-350 PSI (12-22 bar). Note the correct
setting upon commissioning. Modulating units should have a second
pressure gauge monitoring the pressure in the return pipe from the burner.
This gauge will indicate the variation of oil fl ow caused by modulation of
the burner. Gauge readings should be recorded at start-up and checked
periodically.
 DUAL FUEL BURNER  CHANGING FUEL
The following instructions apply only to units supplied with dual fuel burners.
These procedures should be performed only when the fl uid is cold, unless
suffi
cient safeguards are provided to prevent contact with hot fl uid piping in the
vicinity of the burner.
1. Set the fuel switch to “Off ” and the heat selector switch to either “Pump” or
“Off .”
Gas to Oil
1. Turn off the manual gas cocks in the gas train.
2. Remove the gas nozzle orifi ce assembly from the burner.
3. Install the oil nozzle assembly (see Figure 20) and attach the oil whips to
the assembly.
4. Open all oil manual shutoff valves.
5. Set the fuel selector switch to the proper fuel. Restart unit normally
Oil to Gas
1. Turn off all oil manual shutoff valves.
2. Detach the oil whips and remove the oil nozzle assembly.
3. Install the gas nozzle orifi ce assembly (see Figure 21) and open the gas
cocks in the gas train.
4. Reset the hi/low gas pressure switch.
5. Refer to Figure 22 for complete dual fuel assembly.
6. Set the fuel selector switch to the proper fuel. Restart unit normally.
