lotta work quite a bit better

I had the burner guys from my oil distributor try to set up the Burnham V905A to Burnham's spec. After replacing the fuel delay solonoid valve and the spark x-former and a try at the nozzle. The beast wouldn't fire. They set the band the head the pump all to the spec the electrodes were all good. Now the question. Since their spec. sheet was a 2nd or 3rd generation fax copy, the shutter setting was set to 0 and not to 6 like it was suposed to be. Yes the number did look like a 0. Do you think this could cause the thing not to light? Rather than start over with the correct nozzle and head settings it was much better to insist that Burnham specs. only work in the lab. Even the Burnham tech guy I called was quick to chime in with victory when they rattled off the stats from their test probe. That was until I mentioned that the nozzle was back to the 4.0-60 (should be 4.5-45P) and the head was set at 6 and not 2. Burnham thought that the nonfiring problem could have been fixed with air adjustment. His recomendation was to have the contractor call their rep and he would walk through it with them......."No we are not willing to do that". One more find, the chimney is drawing -13"WC they were able to get the beast into a + breech pressure However it was unsteady. I just added my vents and I am warm for the first time this winter. Thanks to the Wall and Burnhams tech dept. Do I pay the Bill?

man you been having a real go around with this....

do you have like a 30' stack and oversized at that my thought goes back awhile to see in my mind some really sooted up clunker with the trans former open trying to breathe...do you have a picture of this boiler and its burner ? i remember using "exotic nozzel sizes like 4.35 at .45 degree with a band setting of around 5.5 or so i probably forgot more than i now know ) i think if you start with he band setting at 4.5 and move it to 5.5 slowly..after it catchesscribe a line on the band shut it down...wait a while like 6-7 mins then refire it... if it immediately refires break out some tools and a bacharach or tesing unit of your choise and catch a stack temp,and smoke. i am not there so the general drift is your wanting thething to run quietly,0-2 smoke and a low stack just for starters..

Weezbo

Well ?

did you give it a go?

Weezbo, the thing is running, just not with Burnhams nozzle or head setting of choice. I am trying to set the thing up to spec hoping to make it as good as it can be. It sounds like the excessive draft may be a factor I'm considering installing a barometric damper to slow this thing down. You are right on with the stack about 30 feet 12 in.

Weezbo

er Yah..... i get the Drift....

Electron drift theory is one of my more favorite topics while preforming these functions i say things a bit different as it were here i am going to probably restate some questions already rolled past you...have any of these professionals gone up on the roof to check the termination of the stack? and did you say that this boiler doesnt have a barometric installed ? and did any of these workmen bust out a book or loose leaf early on in the game?

thfurnitureguy_2

Stack terminates 3" short of the moon this is why it has the monster draft. Also it is large enough to suck up a whole ream of loosleaf paper at a single gulp. in fact I saw it spit 16 dead pidgons out the top and still have enough draft to cave the walls in on my basement. OK you got me. What is it about stack termination I dont get? I dont think its plugged up.

Weezbo

i would say that is a distinct likelihood

Some hecka deals i have seen in my few brief encounters with these er variant conditions....some days only by going there and actually getting a visual can these minor technicalities be explained..sometimes the opposite condition arrises numerous atmospheres of positive pressure only a forced flow of air through the vent get a fire to raise the combustion air out of the building...this may have been done by designe in your case as implausable as that may sound... the last 14 " i tied a plastic army man to a plastic bag from a grocery store and sent him up the shoot ran outside and watched him fly up out the pipe and away and parachute a horrible death back to the ground i have a bunch of this huge metalasbestos type L pipe and fittings sorry i digress...er :)well now in my professional opinion ) barometric damper are ok uh even though its oil it still needs some outside air for combustion...in your case it might look like a big tin box along an outside wall. this may have been how to say Re matriculated so ,now that particular box is somewhat part and parcel of some of the draft ...some times it redgisters rather heavy on the entire deal...Glenn has been doing his level best to keep everything on track and focus furniture guy...what he is saying real short and sweet is that these puppies have very specific settings and requirements..when some one changes the fuel pressure then some one else changes the draw, then another guy figures its the air band ...this is not a habby situation... these thing like i say are heavily imbued with the power of enlightenment...meaning they can wake the unwary up in a heart beat..:)a few of the guys here Know Exactly what i mean by that...and indeed they have experience..see where i am going with this line of thought? the reason the learning curve isnt left up to trial and error is because minor technicalities produce some real world concequences... from a distance these things explained to the right ears ignite immediate recognition of where to go and what to do..and perhaps even more importantly ..what not to do... did you go check Oil Tech Talk? some of the very men you have been discussing this with here ,also share old and new ideas and communicate at that site also...

yes we have the big tin box. yes we have a small huricane of very cold combustion air running thru said hole in wall box. Was that way when the pros were here. I would like to add a inward louver on that one also. not yet. I take it Barometric dampers do a number on available combustion air. Send the room negative? One more tid bit, there is a second flue next to where the boiler flue enters on the chimney. It has a couple of bricks separating the two and I don't know if it is a separate flue all the way up but it is open (had a water heater flue that the other owner kinda removed) I had no luck with "Heat talk" I will try on the home computer later. Thanks!
