Damper on oil furnace burner motor

[andrshaw_3]

I was wondering if the little air vent on an oil furnace burner blower should be opened or closed? The reason i ask is that when the furnace comes on the air coming from the floor vents is not very Hot so i opened it up a little bit and it kinda seems warmer. So i was wondering if messing with it will screw up my furnace???????

Are you referring to the stack damper with the weight?!?!?!??!

il post a pic of it....

no... thats one's ok....maybe damper is the wrong word...this air vent thing is right on the burner motor...

Ok you are referring to the air bands on the burner
unit... Ok My Friend What kind of burner is it a Beckett Burner?
Carlin? Blue Angel? Riello??? Important to know also
What size boiler 3 section 4 section??? Also What size
Nozzel is in the unit is it a .85 80A or B or Es?? This is important to know
being an 80A is a Hollow Cone Flame an 80B is a solid cone flame
also es is a semi solid cone .85 stands for 8 /10's of a gallon per hour
depending upon the boiler that is going to dictate the size of the nozzel
if you don't know how many section it is post the btu load....
Normally what i did like with a beckett burner i adusted my Primary
airband to 4 and just barley cracked the secondary air band...
Also look at the site glass if you can see the fire loosen the airband
then back the secondary closed and back down the primary.. When the
fire gets smokey start to open it up until the smoke is gone.. Once it is
gone lock down the air band adjustment... turn it on turn it off make
sure you have no Delayed ignition and no roar when it shuts down...
These are just basic steps i really need to know the burner the size of
the nozzle the degree of the nozzle which the 80 stands for.. it could be a 70 degree flame cone a 50 so on and so on... if you are having problems
with it and the flame is sputtering... I would recommend changing the
nozzle cleaning the flue passageways.. Changing the Strainer in the oil pump.
If it is a webster oilpump it has no strainer but if it is an A pump then it
has a strainer they are usually marked.... Let me know

Duh,
there is the photo didn't see it Argh ok it is a beckett
it has an a pump strainer those 4 1/4 inch nuts you shut the oil
supply off and then change the strainer... Also it probably
has a gf 111 filter inline would recommend changing that... On top of the
oil pump it has a delay solonoid Another thing to look for if it isn't warm
enough is a plugged nozzle when was the unit last serviced by a
qualified Hvac guy? normally an oil burner is a must do at least once
a year... To change the nozzle on that unit you must flip the top transformer
back MAKE SURE YOU TURN THE POWER OFF OR YOU WILL REGRET IT!!!!!!
As in Complete Electrocution by 10,000 volts and it WILL HURT YOU I PROMISE!
I cannot stress that enough... Then remove the oil line tube going to the
nozzle assy and then pull it in lift up on the end of the nozzel tube and
slide the tray assy out... The end of that is the nozzle i do believe it is
5/8 also you will see two electrodes... They are set 1/8 of an inch apart
an 1/8 of an inch in front of the nozzle and 1/4 inch above the nozzle
so they do not ground out on the nozzle itself... They ignite the
Fuel... Remove the nozzle replace it with the same size and then
set the electrodes reverse the removal procedure fire the unit up
and set the airband the way i explained in the previous message that
should get you in the ball park...

when i look in the tiny hole i can see flames. im not sure about all the other stuff. I know its a beckett burner and before i played with it that air inlet was completely closed...which i assume was done by the company that installed the furnace. I just opened it a crack to see if i could get a little more heat out of it. The more i open it the less flame i see in the hole. Where it is it starts ok with no delay and no roar. Cant really see in that much through the hole because its very small...

[rob318us]

The only time you would have the intake door all the way closed and is very
seldom is if you live i a higher altitude..But i would say you wouldn't want it
closed all the way.And as said how does the flame look in the little sight glass
on the furnace..And is there any black smoke comming out of the chimney
Sounds to me like you either have a dirty filter or clogged nozzle but cant be
100% sure..

[andrshaw_3]

Here is the sticker with the info...i think

There is no black smoke...i just did not know if that thing should be closed or not. I live just outside ottawa so i dont think im that high up...Also when i look in i can see the tip of the flame...

[Mondoman22]

Wow with the airband shut the fire will run rich and
soot the unit up in no time.... It is a warm air furnace...
You need to let me know the btu load on it....
it will be on the dataplate... If you open the air to much
you will blow the fire out you do not want to do that......
As it will cause it to rip and snort and basically scare the
hell outta everyone in the house... I would suggest backing
off the air on the unit look at the fire and see when the flame
gets lazy and smokey then open it up little by little until the
flame clears up and lock it down.. you should just have to use
the primary air band there are two on that unit one that wraps
around the oil pump mounting housing and the primary which is the
one that is on the side of the secondary where the oil pump is
mounted to... close the secondary and just use the primary
if it is a small nozzle all you should need is the primary air band..
Also there is what is called a camstat on that unit a little silver
box when you pull the cover off you will have a dial in there
in the dial there are three tangs.. 1st one turns the fan off second
one is the fan on 3rd one turns the burner off being High Limit....
there are degrees make sure the second one is set at 140 degrees
so the chamber gets to 140 degrees before it turns the fan on
set the first one to 100 degrees it will give you a 40 degree spread
do not mess with the high limit.... Leave that where it is.....

its an 85000 to 97000 btu. The air band is just opened a tiny crack. about the space of a butter knife.

[Mondoman22]

Ok it is a delevan .65 80 B nozzle it is a small one.... ok
set your primary airband to the number 4 close the secondary...
Now check the cam stat make sure it is what i told you to set
it at... If that does not help the nozzle filter and strainer must
be changed... I don't want you to do something you are
not comfortable with so i would recommend calling a service
tech out to tune it up... Oil burners are Finicky creatures and
if they are not set up right you can have one hell of a mean
azz puff back where the oil loads in the furnace and then
Ignites... You DO NOT want that to happen... It will soot
the house up scare the ever living hell out of you Oil fires
are not easy to put out either..... No 2 heating oil is nothing
more then diesel fuel.... Believe me don't mess with the thing
unless you have some mechanical experience.... It sounds
to me though that it needs to be cleaned and Serviced
I hope the stuff i have gave you is helpful...

Air band one is opened....
to it looks like 4 or 5 on the burner Photo.. That silver box to the
left is your limit camstat control... That is an armstrong unit
it is a 4 ton drive furnace and it is an 03 from the serial number...
its a newer unit... You should not have problems heating the house
with it... I will Tell you if you havent had it cleaned Please Get it done
right... Like i said Oil burners are Not Forgiving Creatures and if you
have a puff back you will not be a happy person i promise you...
I have been doing heating and Air for 25 years... i am Nate certified
Boilers Chillers Ammonia Systems Heatpumps Hydronic Gas oil fired...
You name it... If its out there i have worked on it... So believe me
when i tell you just be careful with what you are doing... Like i said
before i hope this helps you out....

the fan switch thing is set at...
the first one is at 100
the second one is now at 140...it was 120
and th third one is at 200

the air band it at 4 now...it was set to 4 when i opened it the other day.turned it off and restarted and there was no poof...no bang....just a normal start up

[rob318us]

I would agree with Mondoman22 on having a service tech out to look at it
because like hes saying if the flame goes out while messing with the dampers it will load the chamber up with fuel..And most definitely scare the heck out of everyone when it re lites it can boom very loud and after it goes out from the boom the fuel will still burn in the chamber till it all burns out...Oil furnaces are very touchy and can be dangerous if not knowing what your doing..

[Mondoman22]

Ok good,
Like i said if this does not help you Have the thing looked at
by a service tech.... If you need anymore help just hollar
Have a good one be safe!

i opened the air band the other day and it has made a diffrence. The only thing i adjusted tonight was the fan control. Workin good now...just wanted to make sure i was not damaging anything by opening the air band a bit. Like i said...it was completely closed for like the last three years. Burn a whole tank of oil in less then a month. I cant afford to call a service tech....im close to being super poor....

Everything i do in this house i try and do myself...cant afford to pay anyone. I am a drywaller by trade...not a heating guy....so i pick stuff up as i go. Hell took me four days to learn how to prime my water system after i replaced the Foot Valve. Thanks so much for the help. And this is a big house to heat. 7 bedroom house...lol

Tony

[andrshaw_3]

Thanks tony. It has not been serviced in over three years so i bet its about due....i replaced air filters but thats about it!!!

[anyonomus]

Instead of hitting the reset when a customer calls ..why not light a piece of paper and place it in the inspection port door..then if the person has pushed more than once ..the lit paper will allow the oil in the pot to burn without the puff-back from the burner igniting it..(just a thought from and old fart)
Glad u got it working a bit better andr.
any

[3000mw]

Thats what I do, light a rag and toss in the inspection door on larger oil furnaces...
