Test method Outcome
Step 1
1. Detach the hose that leads to the 1- and 2-stage capacity
valves, and is lead to the drainage container.
2. Detach the main valve conductors.
Step 2
Start the burner and pay attention to oil that is possibly dripping
from the disconnected hoses.
The burner enters lockout after pre-
purge, because flame does not form.
If the valve is proven to be leak-proof,
connect the hose back to its place.
If oil is dripping, change the valve.
1- and 2-stage valve leak testing
The main oil valve is kept open longer than the normal safety time, by creating an
simulated flame signal during the ignition phase. The simulated flame signal enables
longer testing time for valves.
The creation of the simulated flame signal has to be timed to the ignition phase, that
follows the pre-purge phase. Premature timing leads to a burner failure due to a foreign
flame observation, and delayed timing leads to a burner lockout due to missing flame
signal. The action must be performed within the safety time (5 s).
The safety time starts when the main oil valve opens. You can observe the opening of
the valve from a clicking sound. If you cannot observe the sound, you can verify the
valve opening from valve coil magnetization. You can verify this easily by keeping an
ferrous object (for example a screw or tool) near the valve coil.
