Laars Mascot boiler’s faulty oil nozzle

Hello Everybody,

I have bought and installed my Laars Mascot boiler two years ago. From last few days, I am noticing that the boiler’s oil nozzle is not working. I have tried to fix the problem after reading the user guide but unfortunately, the problem persists. What is the matter? Is something serious?



Hi Mark:

You are facing this issue due to the following reasons:

  • Air in the central heating pump
  • No oil in the boiler’s central heating pump
  • Damaged pump or drive
  • Chocked oil nozzle
  • Damaged mechanical shutoff valve

For fixing the problem, you have to do the following things:

  • Check & refill the tank or oil-line
  • Check or clean the filter or regulators from the boiler’s oil tank
  • Bleed the central heating pump
  • Clean or even replace the damaged mechanical shutoff controller
  • Clean or replace the nozzle
