The new boiler is a Burnham PIN6 Ė which is a little smaller the original oil fired boiler that proceeded it. The Pin5 was slightly to small and the Pin6 was just a little to big. We went with the larger unit so when we put the addition onto our home we have some room to expand the system.
The installer has suggested that the boiler is surging, and causing the water level to drop by sucking to much water into the mains during operation. Iím not sure that make sense to me, but I mentioned during the installation I didnít think the near boiler piping was correct (I have a very low ceiling). What can be done if a gas boiler is over firing? Shouldn't the cut out have shut down the boiler?
The installer is coming on Friday and I want to make sure that he fixes the problem and doesnít give me some run around of excuses.
Thanks for any help or suggestions
: Good operation is to have steam up with all radiators heating in ten minutes. In the cold winter, a run time of 45 minutes out of the hour is good.
: Unfortunately, many install boilers with burners larger than required for the radiation, which makes the heat-up time very short. The water dropping shouldn't occur, so you have proof that the water is being thrown out of the boiler from too quick input. The pressure overshoot is another indication of excessive burner input; though new boilers have thinner castings that heat up faster than the old and usually carry less water in the boiler, often requiring some design 'fixes' to adjust the new boiler to the installation.
: Several checks of what the burner input is on the nameplate, make and model of boiler, the radiation square feet of surface and other info can further inform about solutions to your incorrect installation.
