Old oil furnace nozzle compatibility

AGA_Pyro_Job · March 14

Hi All,
Let me know If I am not at the right place..

Does anyone know know about thoses furnaces?
Does anyone have the user manual or know how to find it?

What are the compatible Nozzle?
Is a .85X80W nozzle compatible? Would it need special adjustment?
I know the first number is Oil flow (GPH), second number is the angle and the letter is the spray form..

But it's not that obvious on that nameplate..
Is 1.10 my first number? then 80°? the form is then R?
(if the angle is 80° the punch used had issues 🤣)

It also made noise like said in that thread. But more a rumble noize at start up..

Thank you all,

What burner is on that furnace?

The label tells us a few things:

1- the firing rate is 1.10 gallons per hour (GPH);

2- the spray angle is 80 degrees;

3- the spray pattern is "R". This was probably a Monarch nozzle with a solid spray pattern. We don't see Monarchs much anymore, but there is a cross-reference here on page 21:

So, assuming this is correct, the replacement would probably be a Delavan 1.10x80B. BUT……..

This must be verified by a competent service person having the proper tools (flame mirror, combustion analyzer etc) and the proper know-how.

Looks like you're in Canada. This site has a "Find a Contractor" page, but it doesn't go to the Great White North.

I will ride the coat tails of this post with same question. I have a Riello F3 that operates fine, but once had the wrong nozzle installed. Firing rate on American Standard boiler is .75. I have a competent oil burner guy that uses a 60/ .75 nozzle or sometimes a 60/ .65 nozzle. This topic is beyond my understanding and appreciate any input

Regards,

Keep in mind that the stamped firing rate of a nozzle is at 100 psig fuel pump pressure. Many modern burners operate at higher pressures, meaning the nozzle will fire at a higher rate. This can be calculated.

Some techs on a service call will not have the correct nozzle so they stick anything in the burner which may or may not cause an issue.

The customer would be better served if the left the old nozzle in the burner . Contrary to popular belief nozzles almost never wear out. They can get plugged with sludge or dirt and can usually be cleaned but do to their low cost they are just replaced as a general rule.

Putting the wrong nozzle in is a bad thing.

According to the rating plate (which looks like it was made on my mom's old Royal Typewriter) there is a Barriere oil burner model JI-G (X) which could be anything from an old 1725 RPM non-retention burner to a modern Wayne,Beckett, Carlin of other brand that was relabeled with a Barriere label.

Also the firing rate of 1.10 GPH US is the maximum input. It may be quite acceptable to fire it lower that 1.10 GPH. The original instruction manual would give you the needed information. Also a picture of the actual oil burner would be nice to look at.

Some time after 1972, it appears that the Barriere furnaces were made by the Lincoln Furnace company and that shows up in the Beckett OEM guide, but there is no mention of the LAO series furnaces. So I would guess that your burner is not an RW Beckett product.

@EdTheHeaterMan

Wasn't there at one time an "Aero" burner made in Canada and maybe some were in the states as well?. I remember some called it a Canadian Beckett.

There was. I think Beckett bought them out.
