Burnham LE-DV (Steamhead)

Tundra

Bill, you're right. Cut back on the air as much as you safely can. I have seen impingement on the turbulators. I believe an NX or Pioneer option would be a benefit to these boilers.

Thinking of using this boiler

where the existing chimney is a mess. It will drive a system which is mostly baseboard, and a new indirect. Anyone have experience with these boilers?

done the LE

I replaced a system in tight quarter's last year with the LE series. I did make sure to follow all installation instruction's and a year later the customer is a very happy person. I have yet to do the dv but have serviced two of them and the customer's were happy with both...

Make sure you get the draft set right. The flame likes to impinge on the turbulators.

No

No draft regulator on a DV.

chimney liner?

The LE's a great little boiler. Very quiet with a Riello. I'd try to put a liner in the chimney if possible.

As already stated by others, the LEDV is a very good performer provided you cross all of the "T's" and dot all of the "I's". There are basically two rules that need to be followed with this boiler:

1.) The LEDV needs to be installed as a Direct Vent boiler with combustion air from outside piped directly to the burner. The orientation of the vent discharge and air intake must be on the same wall and need to be a minimum of 18" apart.

2.) The LEDV must have a "System Bypass" or bypasses in order to keep the vessel above the dew point due to it's small mass (6 gallons). If you are using multiple pumps, you will need multiple system bypasses. It is much easier to use this one with zone valves and one pump as that will only require one system bypass.

As far as the impingement that Tundra described goes, generally I only see this happening where very short distances of flex vent pipe are used. We sell four lengths of vent pipe for this boiler....5', 10', 15' and 20' lengths. Most only require the 5' length and in many cases that seems a bit too long so they get cut down even shorter. I try to advise using the whole 5' length and bending it into a letter "P" configuration in order to provide some back pressure which will keep the fire on the head better. Hope this helps.
