This has me confused. That pilot fitting is tapped right into the steel
reducer fitting, coming from the gas supply. That does not look
original. I've never seen such a thing!!!!
Yet, the OP said that if he shuts off that 'internal' gas valve, which
is AFTER the pilot, the pilot wont stay lit. That makes no sense to me.
That internal valve should only supply the main burner with gas.
Either way, there is no known control. There HAS to be a control of
some sort. You cant just leave the thing burning full blast in any
temperature. Without a control, it would continue to burn full blast
even if the weather warmed up outdoors, and could make the house so hot
it could cause a fire or at least start to melt and damage things, if no
one shut it off. Antique or not, they couldn't have been that stupid to
design it without some sort of control, even in the 1940's (which I'd
estimate it to be).
I'm thinking the OP is missing the control. I still think it's inside
that side door panel. There may even be a pilot shutdown device in case
it goes out. Otherwise why would the pilot go off when the main valve
is shut off.
I wish the OP would post the make and model of this heater, as well as a
photo inside that side door.
Using Google, and going to IMAGES, I searched for "old natural gas
heater". I did not see one that matched the front of it.
I did find this ebay page which has lots of pics of old heaters. Some
of them are just fun to look at.....
Then I found this one.
That's identical or very similar to the one I had years ago in my rented
house. So now I know I had a "Monogram" brand heater.
That brings back some memories! Those ceramic tiles got red hot and
added a nice glow at night.
Hey! It worked!
Sorry for the delay, I left to go to dinner (but I turned the gas off first
I read through all the responses and the insistence that there must be some
burner control led me to spend a few minutes running my hands all around i
t to search for anything else. After not finding anything, I decided to exp
eriment more with the one control I did find inside the panel.
The little valve in there -- when it is turned all the way pointing towards
me does indeed turn the burner off, but at an intermediate angle I could h
ear a hissing from inside the vent, so I stuck my lighter in there and it a
ll lit up.
Thanks for all the words of caution though, I'll only run this while I'm aw
ake and get my room nice and toasty before turning all the valves to off an
d falling asleep.
For some of the other questions -- no make or model, this apt is quite old
(early 19xx) and I'd imagine so is this space heater. Also, the thing is on
e solid unit, nothing comes apart, only the one little door opens. Lastly,
there is a large ceramic plate in the front of it that you can see through
the front grill. And oh yeah, the ethernet cord, it wasn't routed through,
but since I never anticipated using the thing I was not cautious about what
cluttered up around it. It's all cleared now though.
Make all of us safety conscious types feel better and don't use that
thing much at all until and unless you go to your favorite big box store
and get a carbon monoxide detector for the room where your space heater
is. Just because it is supposedly vented to the outside doesn't mean
that you can't have problems with CO, especially with such old hardware.
In any case, if you find yourself getting at all drowsy, nauseated,
confused, dizzy, or otherwise feeling unwell, turn the gas completely
off, open the windows and doors, and go outside for at least 1/2 hour
and let the room thoroughly ventilate. If you don't feel better after
that time or are feeling worse, seek emergency medical care. Better
safe than dead.
Didn't have time before...that's an old "wild pilot" setup--didn't see
if you ever said where you're located but no jurisdiction I'm aware of
allows those any longer--here, if a service tech even sees one he's
_required_ to disable it immediately until it has a safety pilot installed.
I've one of early 40s vintage in the well house that I retrofitted a few
years back. By watching eBay I managed to do it all for very reasonable
price of only about $25 overall including the valve, a new pilot
assembly and thermocouple.
I'd _strongly_ recommend doing the same there--mount the actual valve
itself on solid pipe outside the heater where the present flex starts.
I'll try to find time to take and post some pictures of the retrofit
here as guidance. It's not difficult and adds a tremendous amount of
Here's the type you can use...this is 3/8", not sure whether that's a
3/8" or 1/2" line but 3/8" should be plenty of capacity for that heater...
Need a pilot light assembly and thermocouple to go with it and you're done.

I can see from your pictures that this is an old apt. Of course, that
is not bad. I like the look of the old WIDE woodwork and like the plate
around the chimney, its decorative. Kind of reminds me of my
grandmothers's house from when I was a kid.
The heater has probably been there since the bldg was new. The ceramic
is not visible in your pics, but that is how they were often made.
There is likely a MICA window over it.
Apparently that inside valve /IS/ the control. I wonder if it would
shut off when the room temp gets to a certain warmth.
There has to be a way to open it, there may be screws on the back, and
the whole outer shell (enclosure) comes off. But you dont need to do
that now. I'd think that there would be a label somewhere on it. Back
then (like now) they want to advertise their product. But maybe someone
removed it. I'd suspect it on the rear, since it's not on the front.
It looks to me like someone braze welded that door hinge. The shiny
brass with white coating (flux residue) around it.
Anyhow, it works and you're warm, just be careful with it. And I'd
still ask your landlord what he knows about it when you see him. He
might know more.....
If anyone happens across a web photo of this same heater, please post
the URL. I'm curious what brand it is.....
Note: That Monogram brand heater I said is the same as the one I used to
have, has multiple photos on the ebay page, and the cover was removed,
and exposes a temperature sensor above the heat exchanger. But that
heater has more for controls and a safety shutoff. (and is likely about
10 to 20 years newer.... I estimate 1940s).
A lot of people felt that way on New Years Eve, but it had nothing to do
with any sort of heater, or gas <LOL>
On a serious note, the OP could test to make sure the chimney is working
by simply holding a lit cigarette in front of the chimney pipe. (Yea,
you dont have to smoke it, if that offends you)... If the smoke is
sucked up the pipe, you know the chimney is working.
A low tech way to check a chimney, which has been used for ages....
OP here again. After it started burning I began wondering about the state o
f the chimney and some google searches suggested the CO could be a problem
in inadequately vented natural gas burners (especially where the burner may
be dirty or otherwise unable of fully burning the gas). After about 30 min
utes I noticed I was feeling dizzy, so I opened my window, turned on a fan,
turned off the heater and went outside for a bit.
A while later, after getting sufficiently paranoid, I remembered a CO alarm
that I had neglected to set up (won't make that mistake again) and turned
that on, tested it and set it in the room with the furnace while I went out
The alarm never went off, so I put on some winter clothes, bundled up and w
ent to sleep with a window open and the fan running. I suppose the overall
draftiness of my old windows was a boon in this situation. Not the best nig
ht of sleep I've ever had, but I'm glad I caught it when I did.
Probably preaching to the choir but get CO detectors! Could have saved myse
lf a headache and a lot of worry had I taken the time to set mine up.
There are units that use a thermopile to power a gas valve (with all usual
safeties) thru a thermostat . Best bet for safe controllable heat ,
especially since he is vented <assumes vent is functional ...> .

If you plan to use the heater again, test that chinmey. If you dont
have a cigarette, light a piece of paper and see if the smoke gets
sucked into the pipe. (Have a pail of water to extinguish the paper).
If the chimney is blocked, dont use the heater till it's fixed. If not,
I think you need to talk to your landlord for a newer heater.
You really did not have to leave a window open of fan on all night. A
half hour with open windows and fan should have aired out the house.
If the CO detector did not go off, I dont think the heater was leaking
fumes, but it's hard to say.
You might be better off just getting an electric blanket and one of
those small electric ceramic space heaters, since you only need this
All newer furnaces and even gas water heaters use that now. Even the
self igniting gas ranges. It saves gas. THe pilot light is small, but
it works all the time. That does eat up fuel over time. In the summer,
I always shut off the pilot on my older furnace. No sense wasting gas,
and adding heat to an already too hot house. In winter, that little
pilot light adds to the heat, so it's not that big a deal. I do like
the self ignitors though.
Some use a heated coil, others use a spark gap. The gas kitchen ranges
that snap, use the spark gap. (Basically a spark plug sort of device).
If no one said this already...
It looks to me that the little silver screw in the side of the small pipe
Is the control for the pilot. Use a screw driver to control the size of
The larger handle is the valve for the main burner.
If you are going to light this by hand with your lighter
You dont need the pilot, screw it all the way in.
If you don't already know all this, this thing is dangerous for you to use.
Get a co detector.
Dont leave it on unattended.
Get some help from someone there.

Per my comment/suggestion of a day or so ago, I did take some pictures
of the well house heater with the new safety control valve and updated
They're at <http://imgur.com/a/3ggB8
First one for comparison shows the old wild pilot valve; it was where
the safety control valve is presently. These pieces are generally
pretty carefully sized; the length of the new valve body is the same as
that of this one; didn't have to change the piping itself at all.
Second is an overview of the setup, then one of the new pilot
assembly/TC in place. I bought it locally at a HVAC contracting shop so
could compare orientation with the original in selection one that would
fit and have the flame in the proper location. One can see the burner
feed at the bottom and the pilot feed tube and the thermocouple lead at
Then the new valve in position and a couple of the original temperature
control; in the first of those two, that's its thermocouple lead wrapped
around it in loops; the TC body is the larger horizontal "tube" above
can see a little of; it fits in a bracket on the back of the heater or
could be moved elsewhere. As can see from the dial, there's no
calibrated temperature settings, just markings from low to high. In the
well house I keep it at the minimum and it stays between 55-65F
depending on just how cold it does get outside. It's an uninsulated
block building as can be seen from walls but I did add 6" fiberglass on
the ceiling that helps...
Hope that helps visualize the setup and that it isn't that complicated
to make the existing heater _much_ safer. Now if the pilot does blow
out, there is no gas flowing; before with the wild pilot, it's on
irregardless. It was that way from the early 60s until just a few years
ago and never did have a problem to the level it caused a catastrophe
but it did on several occasions go out and had some pretty good gas
buildup. We always checked on it pretty regularly, though...now I don't
have to worry about an explosion when the pressure switch kicks on but
only ensure that it is still lit so.
