Well, I haven't finished the series. At the time that one was done, I did not have a furnace set up to finish the series. I have one now so look for more on this soon. Thanks for the patience, GFM
Hello Sir. Thank you for your videos. My SundStrand (B2VA-8216) has a gauge port on it. Do I just connect a gauge to it and not need to disconnect the tubing to the gunline?
The tech probably increased pressure to increase efficiency due to better atomization. The smaller nozzle was to compensate for the increased pressure. If the nozzle is very small, it could plug. It does sound like a supply problem though. Fire the unit off with the gun line into a can to see if flow is continuous. Good luck.
Hi Gary, thanks for your videos. I have a Miller furnace burning kerosene from an outdoor tank which is about 2 feet above the burner. I am having leaking at the burner which I’m thinking is “pump flow through” ? I’ve changed pumps in the past which appears to help for a while but reoccurs. I’ve seen pumps with an electrical connection and wonder if I should switch to that type. Any suggestions would be appreciated! All my connections are tight. I’m thinking the kerosene is getting through the pump and dripping out the nozzle. One line system. Didn’t run the furnace all summer and it still happened.
smaller nozzels are sometimes used when flame length is a problem,a smaller nozzel with a higher pressure gives shorter flame due to better atomization(the droplets are smaller and burn quicker)most new burners with retention heads are on 140-150 psi now-just a thought
If im testing the pressure with a gauge manifold(sid Harvey pump testing manifold) I have one line connected to the outlet of the pump(where the jet tube connects )and the other hose to the nozzle assembly.my manifold kit has pass/fail tests written under the case.i open the handle and fire the burner so I can watch and adjust the fuel pressure .it then instructs me to close the handle on the manifold and quickly turn off the burner .the pressure should not drop below 25 psi it says.but the pressure dropped to 0 on the unit so I was testing .it was a new lennox oil furnace with a becket nd burner and clean cut pump. I doubt the pump is really bad ..did I do the test wrong or am I missing something .please respond! I need your valuable input
Does this test only work on the gun line? I hooked a gauge to the gauge port on the top of a suntec pump... It goes to 100 but drops immediately to zero Again, this was on the gauge port
No It maintains pressure reading when running But drop to zero on shut off I have a suspicion that the gauge port it's only for psi adjustment. I didn't try the gun line because I didn't have the proper adapter at the moment Was just wondering if you ever tried plugging into the gauge port
@@grayfurnaceman OK I tested again.... Here are my results. suntec pump. On the GAUGE port I have 100 psi..... shut it off..... DROPS to ZERO right away. On the GUN LINE I have 100 psi ... shut it off.... drops to 80 ish and HOLDS So, Obviously there is a difference in the gauge port and the Gun line... hopefully this helps. please test this on your own if you get a chance. Thanks.
My pump has a new 0-300 gauge installed on it. My running pressure is 100 lbs. The pump bleeds down immediately when shut down. My furnace seems to run fine and flame doesn't fail. Are there issues?
I fyou are worhing on the burner with the burner on, reack=h over and flip the switch off- does the burner shut down the same way as it does when the boiler control shuts it down? With or without solenoid pump?
Hi gary, I greatly appreciate this video. I had a pump that was giving 100 p.s.i , but crashed to zero. The new pump holds at 90 p.s.i after it checks out. My question is if the pump was starting to fail would it have gradually went to zero or just checked out at a lower p.s.i like say 40, 50, or 60?
The reason for the normal 20% drop is the relief valve leaking by. If the valve is leaking by, it will generally drop to zero, usually slowly. I have never seen one drop to a lower PSI. GFM
I got 8 of those units in my gradge collecting dust not I can check the pumps. I think i blew the seal out of one of them trying to make a forge im pretty sure i over spun it 3k rpm was a bit more than bypass could handle
Have a question I have a Beckett DS901 oil burner can I install a quality preasure Gauge and leave it installed on my unit would it hurt anything to leave it installed? Obviously not with a hose like a test Gauge. Just a quality liquid filled Gauge?
I've been looking for a pressure gauge so I can do this, but all the ones I find only go up to about 100psi. I need something in the 250-300 PSI range. Any recommendations?
If the burner runs for that long in one cycle, I am betting on a problem with oil supply. Plugger oil filter, plugged line, oil tank with sludge in the bottom. GFM
grayfurnaceman Thanks for reply! I want to build pressure test setup to attach to gunline. 1/4" guage to 3/16 male flare should do it... Carlin burner Genisys control. Reset from soft or hard lockout, will hitting reset again for 1 sec as soon as motor runs initiate a 2 min purge cycle? If so, is that true for most Beckett and Carlin burners?
Checking it the way you are doing it is called dead heading. That is not acurate the guage should be in a tee with 2 lines in place of the "gun line"as you call it. Check it on the run for a TRUE oil pressure reading.
Hello Furnace Man... so I'm hoping you can help. My oil furnace needed to be reprimed as it ran out of oil. (I'm never going to let that happen again). Its a Mectron M5 type 217T. prime port was not all that obvious because it didn't have a nipple on it. So in the process of locating the prime port we accidently adjusted the pressure port. Is there an easy way to find out what pressure it should be. I have added a pressure gauge to the prime port as I could see no other place it fit easily. The burner runs at 100 psi but I'm not sure if that was the initial setting.
so i did install a gauge at the "gauge port" and the gauge works!!-- after burner shuts off the gauge drops to 0 psi--soo... it IS the pump- the regulator is not holding pressure!!
+grayfurnaceman If he was using the gauge port how would the pump still hold pressure if what you call the "gun line" is open and any pressure will bleed right out the nozzle? No?
+bigpardner From what I am reading on "suntec installation and service manual" IV-10 and IV-11, if you use gauge port pressure will drop to zero, if you use nozzle port pressure should stay at 80% or higher.
This video is a waste if time. You didn't show where the pressure guage us attached. There are several screws in the pump. One of them is the pressure adjuster. I expected that you would show us how to increase or decrease the oil pressure.All you did was muck around with some spanners and trying to sound knowledgeable
This video is about annual service of the burner. Not pressure adjustments. The pressure gauge is mounted to the gun line. That is the line that moves the oil to the nozzle. I have a video about adjusting pressure here: ua-cam.com/video/fRnmO899I_c/v-deo.html However, pressure adjusting screws are in different places on different pumps. Hope this helps. GFM

If you have closed your tank valve for any reason, make sure you reopen it before you do the pressure test.

You could have a leak in the manifold. I also never used that setup, just a pressure gauge in place of the gun line.

Unless you have a leak at the fitting, it should drop 20% and hold.
If it does not, the pressure regulator is failing.

Where would you check the vacuum on an oil burner? Same spot where you'd check pressure?
At the supply line with the tank valve off.
GFM
How about putting a T fitting in the line then you can run the furnace and check pressure and adjust it at the same time
You could certainly that.
GFM
My pump has a new 0-300 gauge installed on it. My running pressure is 100 lbs. The pump bleeds down immediately when shut down. My furnace seems to run fine and flame doesn't fail. Are there issues?
It should not drop over 20% unless there is a leak in your gauge.
GFM
Have you ever came across a plugged regulator vent that would keep the burner from getting oil?
I can't say I have.
GFM
Amazon has them. Look for: Yellow Jacket 78020
GFM
I fyou are worhing on the burner with the burner on, reack=h over and flip the switch off- does the burner shut down the same way as it does when the boiler control shuts it down? With or without solenoid pump?
If you are switching the system switch off, it kills the power to the entire system.

@@grayfurnaceman ok good to know. I was getting an epic amount of soot output. Basically a years worth in 2 weeks
Don't you need fuel going to the pump for this test?
I got 8 of those units in my gradge collecting dust not I can check the pumps. I think i blew the seal out of one of them trying to make a forge im pretty sure i over spun it 3k rpm was a bit more than bypass could handle
Were do u get the hose for the gauge
When you hook this up isn't the hose full of air, not oil? That doesn't affect the reading?
+bigpardner It has not that I can tell.
GFM
Have a question I have a Beckett DS901 oil burner can I install a quality preasure Gauge and leave it installed on my unit would it hurt anything to leave it installed? Obviously not with a hose like a test Gauge. Just a quality liquid filled Gauge?
I can't say I have ever tried. With some pumps, the pulsing may damage the gauge.
GFM
Good info. I agree in every way.

Try a heating supply store.

Sid Harvey pump testing manifold
I have no oil flow through the gun line but it still comes out the bleeder screw.. is it a bad pump or a relay problem
Does your pump have a solenoid?
GFM
Yes.. I found out it was a bad solenoid thanks
Can i ask when burner runs for 20 mins and locks out is it always the salanoid or pump pressure problem please is route cause
If the burner runs for that long in one cycle, I am betting on a problem with oil supply. Plugger oil filter, plugged line, oil tank with sludge in the bottom.
GFM
parts list would of been nice.
Hi Gary,
Great vid. Is the copper gunline on most burners 1/4" flare?
Most are 3/16" Some 1/8".
GFM
grayfurnaceman Thanks for reply! I want to build pressure test setup to attach to gunline. 1/4" guage to 3/16 male flare should do it...
Carlin burner Genisys control. Reset from soft or hard lockout, will hitting reset again for 1 sec as soon as motor runs initiate a 2 min purge cycle? If so, is that true for most Beckett and Carlin burners?
I have not seen a Genisys that has that feature.
GFM
Checking it the way you are doing it is called dead heading. That is not acurate the guage should be in a tee with 2 lines in place of the "gun line"as you call it. Check it on the run for a TRUE oil pressure reading.
I have done the test both ways. The pressure is the same. The pump pumps far more oil than the nozzle uses, so there would be no difference.

gmoneyga84 If you are sure there are no leaks at the connection, the regulator is bad.

***** I haven't lost any pressure yet this season- same old pump too
running boiler in how oil pressure.???? please ans mee sir
Are you asking what pressure should the pump produce?
GFM
The minimum pressure is 100#.

oil pressure sir
Its a cut off pressure test.
It includes cut off but it is primarily a way to test what pressure the pump is putting out.
