All information in this manual is for
reference and guidance purposes,
and does not substitute for required
professional training, conduct,

jurisdictional/professional codes and
regulations.
Non-Fulton product information is for

from the component manufacturer.
4 CAUTION
Unburned oil, unlike gas, does not leave
the combustion chamber during purge.
5. A scanner mounted on the burner casing and facing the light of the  ame
monitors the  ame.
6. Safety lock out occurs within a preset minimum time in the event of
insu cient, unstable or non-existent  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  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  ow caused by modulation of
the burner. Gauge readings should be recorded at start-up and checked
periodically.
 POWER FLAME GAS BURNER
Adhere to the following for safe starting:
1. Check gas piping, controls and valves for leaks and compliance with code.
2. Check all linkages.
3. Close main gas cocks and pilot cocks. Disconnect pilot line at inlet to the
pilot pressure regulator and purge air from gas pilot line. After purge, close
pilot clock and reinstall line. Open pilot cock. Refer to  ow and instrument
drawing for proper gas pressure and CFM required.
4. Check electrode spark gap (see burner manual)
5. Install gas pressure gauges (if not installed), one at manifold and one
upstream of burner gas train.
6. With main gas cock closed and control power o , turn main power supply
on.
7. Switch control power to “on” position.
8. Check blower motor rotation.
9. Start burner and check pilot. Adjust pressure regulator if necessary.
10. After adjusting pilot with main gas cock still closed, check the combustion
safety controls.
11. With interrupted pilot, the burner should go into safety after trial because
main cock is closed.
12. Also check by closing pilot cock after pilot is established. The burner should
complete its sequence without attempting to open main gas valve.
