Thank you for the video. I'm a Firefighter we were stumped trying to stop the oil flow to a leaking filter. This saved the homeowner from having 100 gallons of oil spill into her garage.
Thank you. I have a mental block about these valves. They are simple but I just can’t wrap my head around screwed out being closed and screwed in being opened. I think your cutaway and demo really helped.
My tag also reads 100deg. but that's 100 deg. Celsius not Fahrenheit. Many are rated at 165deg.F depending on the prevailing code. If they fused at 100 Fahrenheit many boiler rooms might see 100 F during hot summer ambient and would have a problem upon fall start-up. Very nice video. I appreciated your efforts in showing us the cut-away valve.
Thanks for posting; very helpful. Furnace tech suggested I replace my Fir-o-matic valve, which I did; but I actually had it cranked closed vs. open! Thanks for explaining how it all works.
Can these sensors in the fuel line on oil stoves fail without a fire ,? my oil stove oil flow is never constant mine has a sensor with 2 copper wires behind the stove connected to the shut off valve further up the oil line pipe thanks for any advice
Can these fail from the furnace running constantly? My dad visited and cranked the heat way high and the furnace shut off. I tried priming to restart it but there is no oil coming out of the bleeder
That is not where your problem lies. I would look for oil supply problems like low oil level, plugged oil filter, plugged screen, pump or driveshaft failure. GFM
@@grayfurnaceman thanks for the input. I just had service done recently with a new filter at the tank. Oil was also filled recently. There is a splitter before thre furnace, the same line also feeds an oil fired water heater, which works fine. I can unscrew the fitting just before the fireomatic and oil leaks out so its making it that far
Old post here but I have one of these that won't shut off!! I either have to drain the tank but I was hoping to be able to tap it down with a wrench or small hammer. Any advice. Not sure I want to try and use heat on it?
Definitely do not use heat. It will melt the low temp solder and the valve will permanently close. I would turn the valve handle until the handle is loose. Then lightly tap with a small hammer. If it does not close then, you will probably have to drain the tank. GFM
I've been working on my becket AFG after reacent fall cleaning. I was hearing the fuel stop for a second about three minutes into cycle , but then continues normal until done. I found the nozzel was the wrong type installed and electrodes looked rough. So I replaced. Ran smoother , but now shutting off for a sec came back. I wa t to clean the screen in the Suntec pump. And change filter. But shouldn't the furnace tech, that cleaned furnace, have done that?
The screen, if there is one, should be cleaned every 3 to 4 years, or if the contract is a new one, at the first service. That said, your problem does not sound like a plugged screen. Sound like a vacuum leak. GFM
In Mass its 160 degree wheels. Nothing worse than having one of them brake in your hand while turning it. Nothing between it and a cpl hundred gallons of oil :(
Im not sure if I'd have ever figured this valve out, had it not been for your excellently done video!!! Just wanted to shut lines off while I hook up a temporary fuel supply system. Inlet is getting air some how and im trying to locate thel Vaccuum leak. In your experience have ever seen a Firematic valve sucking air in? Im kinda hoping since alternative is in wall or underground.. Thanks again for posting! John
Hi everyone wanted to know what type of valve or cap do I use to close a home oil heating system. Actually I switched my oil water heater to an electric one and now I dont know how to cap the oil system to the burner. And what should I use for safety
First, you hope to never see one. I have used a vacuum pump to reduce pressure in the tank, but any gauge must be removed and plugged. Also no more than 10 in vac, or the tank can be damaged. Lots of negatives here. Hope this helps. GFM
The Crazy Part of These valve is They Never Fully Close You Always Have To Press The Threaded Shaft After Loosening The Knob. So In A Fire Then Center of The Knob Might Melt But The Valve Would Never Close Fully . NOT GOOD
A gas control valve may be installed in any position that the manufacturer instructions allow. Some valves may not be installed with the control knob down. Hope this helps. GFM
This valve is approved as a fuel valve. It is NOT approved as a firesafety valve. It was never not tested to the fire valve standard. See Product notice in 2016 by Morrison Bros Co.
You are correct, it has not been approved by UL. It is however, the valve that you will see on most tanks. Understanding how something works makes service easier. GFM

I just tried turning mine off for the 1st time in my life, and was dumb-founded by it's operation. Thanx for clearing it up.

good job furnaceman
This guy is a god.... Really I find your videos to be incredibly helpful and I thank you for it....
Thanks for the support.

awesome video, grayfurnaceman! heating season is here, so you'll probably see more views coming your way.
This is a great video...great demo and it taught me something for life
Great video! Simple and informative. nice job!
Thanks, this was very helpful. I was doing it the opposite way.
Welcome

couldn't get mine to shut off till I pushed down on it.like you said a little tap.hear video!
+mike pike I found out about that a long time ago when I had oil running everywhere.
GFM
great video. straight to the point
Thanks for the support.

Thanks for the vid, big help

Can these sensors in the fuel line on oil stoves fail without a fire ,? my oil stove oil flow is never constant mine has a sensor with 2 copper wires behind the stove connected to the shut off valve further up the oil line pipe thanks for any advice
You are the man
Thanks for this.
So if this is installed upside down is that an incorrect installation? Also do these need to be discarded after that solder melts?
I would say upside down is incorrect. Yes, if the solder melts, the valve will close permanently.
GFM
Did you say you tap it after handle comes loose to shut it off fully? Mine still leaves a trickle when closed.
Yes, tap the handle. If it still leaks, it either has garbage in the seat or it has failed.
GFM
Can these fail from the furnace running constantly? My dad visited and cranked the heat way high and the furnace shut off. I tried priming to restart it but there is no oil coming out of the bleeder
That is not where your problem lies.

@@bearsgarage272 If there is no flow after the valve, it could be plugged or the low temp solder that holds the valve may have melted.

Also one last question... what is the trick to replacing this valve with oil in the tank?
Run it until the oil is very low, then be quick.
GFM
@grayfurnaceman good answer because don't want to see a homeowner playing the soot vac on the vent trick
I've been working on my becket AFG after reacent fall cleaning. I was hearing the fuel stop for a second about three minutes into cycle , but then continues normal until done.

In Mass its 160 degree wheels. Nothing worse than having one of them brake in your hand while turning it. Nothing between it and a cpl hundred gallons of oil :(
Wouldn't it make more sense to have a 1/4 turn valve and a piromatic valve incase the piromatic valve seal fails?
I think it would be great. Good luck at getting an installer to do it.
GFM
What happens if the valve spring closes the valve for some reason because it gets really hot but there is no fire.Does the valve have to be replaced?
I have never seen the handle sold separately. You could buy the valve and just use the handle. Hope this helps.
GFM

I have not seen one leak vacuum, but it could happen. Be sure there are no ferrel fittings in suction line.
GFM
@@grayfurnaceman ok much appreciated!
always wondered about these..looks like a stop and waste valve inside.
Great look inside! Thanks. With oil feeder coming from top of tank would I be able to take apart the firematic without oil gushing out?
Oil in the line above the valve to the pump may gush out.
GFM
@@grayfurnaceman Thanks for the quick reply! Hope to see you do more videos soon.
Hi everyone wanted to know what type of valve or cap do I use to close a home oil heating system.
Actually I switched my oil water heater to an electric one and now I dont know how to cap the oil system to the burner.

You can install a flare plug on the fitting.
GFM
@@grayfurnaceman thx
Good video. Do you need to replace the whole valve of it pops, or just the handle or just the stem? Thanks
The whole valve will have to be replaced.
GFM
How do you change one of those valves if it fails and you have a tank of oil behind it? Or is that something you hope to never run into!
First, you hope to never see one. I have used a vacuum pump to reduce pressure in the tank, but any gauge must be removed and plugged. Also no more than 10 in vac, or the tank can be damaged. Lots of negatives here. Hope this helps.

The valve on my furnace broke can I still use my furnace
Replace the valve. It is a safety's device.

@@grayfurnaceman can I use any tipe of valve if it fits
Nice cut away
Gary a gas control valve can be install on any position?
A gas control valve may be installed in any position that the manufacturer instructions allow. Some valves may not be installed with the control knob down. Hope this helps.

Couldn't you reset one by pulling the shaft and re melting the solder? That would be interesting.
