Beckett AFG Air Tube Options

Alan R. Mercurio_3

The Beckett M-Series air tube combinations were introduced in the mid-1980's. Appliance designs were changing to improve efficiencies, and European-style boilers with more restrictive heat exchangers and "cooler" combustion chambers were being introduced. These appliance designs sometimes required an alternative to the F-type retention head design to optimize performance.

The key to the M-Series high performance is in their recessed head designs. The V & L head are further back from the end of the air tube than the F head is. This protects the flame base and gives cleaner, more stable combustion in certain applications.

The M-Series designs use two styles of retention heads. The first style is the L1 head (for "locked" or "low"), which is locked on place and used on appliances with low firing rates. The second style is the V1 head (for "variable"). This head has a variable position and is used for higher firing rates.

They also come with two different tube combinations one has a conic shroud and the other has a straight shroud. And of course they are available a in few different lengths.

The M-Series can handle many different situations, but they must be adjusted correctly in order to provide the high performance of which they are capable. Proper adjustment is very important.

L1 head?

Anyone know much about the L1 head on the M air tube that is used on some AFG burners? I have the normal F air tube and was wondering if the L1 head would perform better. I can't find much information about them, and just discovered that they existed yesterday. I saw that there was a thread about this in 2004, but I can't access the archives very well. thanks.

Thanks Alan!

Thanks again for your kind help Alan. Is there a document from Beckett about these heads? I can't seem to find any information on their web site. I would be most interested in the L1 head because my furnace fires at about .75 gph. I have the AFG instrucion manual from Beckett that specifies the adjustments for these heads, but as always I'm interested in more information. Do these heads produce a quieter flame? Are the low NOx also? Do they work better with relatively wider or narrower nozzle spray angles as compared to the F heads? Any information is truly appreciated!

You're very welcome Dirk. Let me get back you latter today to answer some of your questions. I'm going for an early lunch then I'll be in a meeting most the afternoon. By the way I got your e-mail I'll respond to that latter as well.
