Boilers problems faced & solutions

Brands of boilers i’ve experience are Hada Tortise, Sunflame boiler. Both rotary cup type and pressure fuel jet type.

Prior to port, make sure your boiler can be fired, else you’re gonna be in trouble.

Simple maintenance to be carried out, Make sure that the electrodes are clean, Nozzle is clear, Swirl plates are not choked.

Commonly problems for boilers misfiring
1) Firstly always troubleshoot to see if there is arc from the electrode. ( even a small wrongly adjusted gap can cause the arhing to fail) this can be achieved by putting the boiler on manual mode, observing through the peephole, then you push the button for ignition.
2) If there is no arking seen, remove your burner and adjust your electrode slightly.
3) If arking is seen and boiler misfire, problems could be from the fuel line. Check your Fuel Oil filters, fuel pump attach on burner.

Another problem, Black smoke seen on the funnel when boiler starting/ burning.
1) There is a Problem in Fuel / Air mix ratio. Different boiler have difference way of adjusting the Air Damper, some simple, some a little more complicated.
2) The air damper will only open slightly when boiler is starting, Once the sequence for solenoid for oil main burner opens, the air damper automatic opens to position.
3) Sometime the air damper opens too much at start thus boiler misfire.
4) Black smoke arise when the air damper opens too little when boiler is burning, adjust slowly to open more and observe the color of the flame, and also smoke from the funnel.
