7.3 Safety Systems and Warnings
Several systems are built into the burner controls to ensure that the burner operates safely:
Preheater Thermostat:
This device prevents the primary control from attempting to start the
burner with fuel that is too cold (120
o
F). In addition, if the oil temperature drops below the limit
while the burner is firing, the burner will shut down.
Cad Cell:
The Cad Cell detects the light emitted by the flame to determine that the flame is
on. If the burner does not light within 15 seconds, or if the flame goes out for any reason, the
controller will shut down the burner. This prevents the accumulation of unburned fuel in the
combustion chamber, potentially generating smoke, rumbling or misfiring of the burner.
Primary Control:
If the burner fails to light, or loses flame for any reason, the Primary Control
will trip and shut down the burner. To reset, press the red button on top of the primary control.
Note, if may be necessary to hold the button down for one minute to get the control to reset.
Multiple resets may allow oil to accumulate in the heat exchanger, therefore do
not reset more than one or two times. Call for service from an authorized professional if
controller continues to trip.
DO NOT ATTEMPT TO START THE BURNER WHEN EXCESS OIL HAS
ACCUMULATED
IN THE CHAMBER, WHEN THE BOILER IS FULL OF VAPOR, OR WHEN
THE COMBUSTION CHAMBER IS VERY HOT.
7.4 Boiler Startup
Prior to the initial startup of the boiler, it is important to make sure the fuel system is properly
primed to remove air bubbles that will cause nuisance flameouts. Once the burner is operating,
the system is checked and necessary adjustments are made.
Fuel vacuum side leaks that cause air to get into the fuel system are a major cause
of nuisance burner shut-downs. It is critical to eliminate all vacuum side leaks from the fuel
lines!
DO NOT ATTEMPT TO START THE BURNER WHEN EXCESS OIL HAS
ACCUMULATED IN THE CHAMBER, WHEN THE BOILER IS FULL OF VAPOR, OR WHEN
THE COMBUSTION CHAMBER IS VERY HOT. Refer to section 8.5.1 (heat exchanger
cleaning) for instructions on removal of excess oil.
DO NOT START THE BURNER UNLESS ALL CLEANOUT PANELS ARE
SECURE IN PLACE.
