Fine Tuning BioMass

[jaoneill]

I have a biomass 40, am having trouble with upper door leaking smoke. Have cleaned boiler before i started burning and replaced door seal and still leaks any help with this is greatly appreciated.

Have you tried adjusting the hinges and/or the latch?

I adjusted the latch and still leaked. No matter how tight i made it.

What about the hinges; I have found them more critical than the latch. One needs to take the time to ensure that when you are messing with those adjustments that the door is closing evenly all the way around or it will leak.

Ok i will try that, have you cleaned your tubes? If so what did you use?

When you do, since you have tightened down the latch, back it off, then go easy. It may take a bit longer initially, but 1/16 of an inch on the hinges will make a considerable difference in how tight the door is. Take a turn on each hinge, then try closing the door; you want it to take a bit, but not a lot, of pressure to close it. After you have the hinges about right then you can fine tune the fit with the latch.
I have a number of different boilers in different investment properties so I keep an assortment of boiler cleaning brushes of different sizes and stiffness. I just use a medium stiffness brush that fits the tubes.

Ok ill try adjusting the hindges, i shut it down cause of the leaking smoke and couldn't get it stopped and started cleaning tubes cause i thought that might have something to do with it.

Did you get the hinges adjusted? Did it stop your smoking problem?

Well, i found my problem . I had to clean the tubes out. Did that and it has been fine.
Thank you for your help

Can you post a pic of the door? On my EKO I covered the rope with silicone

Ok solved the smoke leaking from the front door by cleaning tubes. Now that temps have dropped in to low 20 and teens at night seems like i cant keep a roaring flame in boiler. Just smoldering at times.wood is seasoned. Any adjustments i can make? Worked well when temps were in low 30's.

Thank you

Try taking the tip of a poker to the intake openings inside the "firebox", then open the front, hinged middle section (my '80 is held closed with two allen head bolts), where the blower is mounted, and take a brush to the airways inside.

 

[Biomass40]

What intake openings inside the firebox? I did the ones behind blower in the front.

 

[jaoneill]

My 80 has what might be termed a manifold on each side with a series of slots on the underside that direct combustion air down across the angled base that slopes into the "nozzles".

 

[Biomass40]

Are you talking about in the bottom chamber along the sides? I cleaned them also.

 

[jaoneill]

No, in the upper chamber where you load the wood....

 

[Biomass40]

Where are they located? Sorry im still new to this.

 

[jaoneill]

Where are they located? Sorry im still new to this.

Along the sides, just above the sloped ceramic floor of the upper chamber. In the first pic the tip of the poker is pointing to this area on the left wall, in the second pic I have inserted the poker into one of the openings.

 

[Biomass40]

Ok so clean along that edge and find and clean out openings?

 

[jaoneill]

You got it. FWIW, I have found that this can at times push crud up into the main manifold which can be cleaned from access behind the blower door on the front.

 

[Biomass40]

The 2 holes behind that door?

 

[Biomass40]

Are there only the intake openings on the left side or both sides of firebox?

 

[jaoneill]

The 2 holes behind that door?

Yup

 

[jaoneill]

Are there only the intake openings on the left side or both sides of firebox?

Both sides on mine....

 

[Biomass40]

Ok i did that and still not getting a huge flame, its heating house but flames then it smolders. Flames up when i open door.
