Adjusting Oil Pump Pressure

[@TerrySeal-p2q]

At last, the manuals never state the operation of the screw in relation to the pressure. Cleared up a problem with a pump. Thanks.

Another good tutorial Fred. Thanks again for showing the basics. Much appreciated.

[@genehunsinger3981]

you didnt mention the plastic basket filter in the pump.I've seen those blocked.

[@joeeye1782]

As a nozzle slowly becomes clogged, will it change the oil pump pressure setting? Also, when tuning up the oil burner assembly (obviously changing out the nozzle) should the oil pump pressure normally be checked ? perhaps before and after replacing the nozzle ? (adding, it may help with diagnosing a problem as well ?

[@alexrivet1732]

Good video. Basic settings adjustment by why do you want to play with the pressure?. Recommended 100psi? Is there math behind that? I'm running 135 on a .75 or .70 nozzle with 140k iBTU input box on a Beckett AFG. My flue measurements are spot on with max efficiency.

[@olddave4833]

there is also a screen in the pump housing.. if you test your pump pressure and if the gauge goes down over 20 percent, you have a leak in the line or the regulator is leaking by. better start looking for a new pump..

[@frederickkosier2508]

You are correct.

never know it was adjustable you learn every day

Type 2 oil isn't flammable when In liquid form. For it to be flammable it needs to be atomized.

Question. I have a Beckett AFG. It has a .065 70B nozzle. The pump was factory set at 156. I need to drop the pressure down to a hundred so I can lower the BTU. Its 83000 and is to much. I only need 45k btu. Using a .50 nozzle will get me to 53k. The furnace has never ran long enough to really warm and keep it that way. Short cycles. I have the low fire baffle that came with it. Does that sound right?. .50 nozzle and lower pressure to 100. I have to figure out if I need a 80a or 70b. The head is Fo and the burner am AFG

[@michaelcash9639]

70b is the spray angle. If your furnace came with a 70b, DO NOT use another angle. You can however drop down to a .5 if you want but air ratio will need adjustment

[@miketyler7616]

I knew air would need to be adjusted. Along with pump pressure. I have to have someone come out because I don't have the equipment to adjust. I've adjusted by eye looking in the barometric damper with a flashlight and smoke test, but I need the gear to do it right. I really need to switch to propane. Oil is just too expensive, and I can get a 96 percent efficient propane that's so much smaller. 2 stage

I'm wondering if these things can be rebuilt or refurbed.

[@sirhc07]

in my area at least not sure if you have a Sid Harvey's but the remanufacture a number of oil burner parts including pumps

[@ShawnPatrickMurphy]

Why do you have the gauge on that end of the jet line? Shouldn’t it be on the other side so it’s connected to the oil pump?

[@frederickkosier2508]

The gauge is on the pump. The pressure that it reads is pump pressure. It’s a gravity fed system so you are reading what the pump is doing.

[@ShawnPatrickMurphy]

@@frederickkosier2508 it seems like the gauge is on the other end of the nozzle how is there any pressure at all

[@frederickkosier2508]

@@ShawnPatrickMurphy the pump creates the pressure and pushes the oil through the tube to the nozzle where it is atomized and ignited. If you have pump pressure your nozzle should be spraying unless the filter on the nozzle is clogged or the nozzle tip itself is clogged up

[@lionwolf5768]

Thank you

[@theoriginalmungaman]

Most pump’s aren’t 100psi, the larger the nozzle the lower the pressure.

[@WhatDoYouReallyMean]

Incorrect. Most oil burner pressures for boilers are currently set at 120 psi not 100psi and never less. Always check the manufacturers recommendations
