Thermo-Dynamics S-85 inspection door

Got a picture? Is it the loose rectangle door hinged on the top?
Should have a gasket to help seal it, but I have no idea where to get one.There was an error rendering this rich post.

The mounting plate around the inspection door most likely has no water in that area you could drill and tap it put an eye bolt there and use a spring to keep the door closed.
Maybe spraying the door hinge with a little WD-40 or penetrating fluid would allow it to close0 -
Yes, there is a sort of rockwool gasket material under the door that should help with sealing, but isn't doing it's job particularly well. It is that top-hinged metal door you're talking about.
As for sealing it, I did think some high-temp silicone might do the job for me - I'm wary of tweaking things too much in the middle of heating season. Just found the issue when I noticed how out of whack my excess air readings were!0 -
I wouldn't silly-cone it. You do need access for over fire draft readings and basic troubleshooting.
I'd probably make and offset bracket that can be zip screwed into the exterior jacket on the left and right, that pins the door tightly closed.
You could also try removing the pin if possible, and adding a spring like @EBEBRATT-Ed mentioned so it's forced closed.
Uglier would be something that holds it shut that's wedged between the door and the transformer.There was an error rendering this rich post.

Thats what I have right now actually, a 6-n-1 wedged between the igniter and the door to keep things shut! There is actually a bolt that can be removed from the center of the door for an over-draft without having the whole thing wide open, but I will look at a way to wire/ziptie everything shut as well.STEVEusaPA said:I wouldn't silly-cone it.

Many older oil fired equipment has inspection doors/ports that don't seal tight and lock.
For Peerless boilers, I'll slip in the correct size e-clip to keep the inspection door tight, otherwise it flops and rattles while the burner is running. For the others, I've come up with all kinds of ways to keep them shut.
Newer equipment, especially those that expect positive over fire pressure, lock down and seal tight.There was an error rendering this rich post.

well....
Yep !!
when I think of a Sight Port, or something
it's like on an HB Smith 28 Series
yep, no tight Seal, but I would not consider this a "Door"
perhaps I misconstrued the OP's question ..?0 -
Here's the 'door' in question. Just an inspection door. Seems like you could slip something over the door and behind the jacket.

oh yea
I rember that stuff from my childhood working for family
that should not leak air that bad !!0 -
It's just the slight weight of the door keeping it closed. But you do see the difference on your analyzer when it's tight vs. loose.

That's exactly what we did with the old Dunkirk 1350's. The inspection door is 4x4 cast iron with a spring hinge that never worked. Every time the burner would fire, the door would open and clank shut. We would cut a piece of 3/8 oil line, bang the ends flat and wedge it through the jacket. The same oil line was used to prop the door open because it was always 14,000° Kelvin.0
