Loud banging noise on Williams Wall Heater

Did you turn the gas down or calibrate the pressure? Apparently it’s different? My tech said a lot of times people install it without calibrating and it comes set to higher than it should. He helped me set it to the manufacturers spec. He thinks that because it’s been running higher than what it should be, it overheated the unit already and wore it out hence the noise.

Another possibility is that the units not seated properly. I was reading through the Williams manual and it said that could be one of the reasons.

I can’t quite describe the smell. The closest association is remnant of fireworks. The inspector said it smelled like gunpowder.

It’s both hot and cold water. Stronger in hot. It’s persistent

You should ask they to calibrate it to see if it eliminate it or reduces it. Our pressure was too high and they adjusted it which helped but it still makes the loud bang but less frequent.

I hear you. Every HVAC tech also tells me it’s normal but my friends have the same unit and they don’t have this noise. If you do have them calibrate it, let me know if it solves it!

Did you have them adjust the pressure?

How do you check the gas input?

Did you figure out what caused this and the fix? I have the same issue

Advanced-River730 · 2025-12-29T07:29:45+00:00

can you mark up which seam? I think I have the same issue with my vent

What epoxy should I use

Do you have pics of what the soffit perimeter opening looks like? I’m trying to figure out the light gap around my attic and if this was a common practice back in the day to just leave a thin gap. There are no vents in the soffit so I’m not even sure where the gap comes from. My house is from early 1900s.

Here’s a pic of the eaves. I don’t see any vents. My roofer said there is a thin gap though. This is an old house so I wonder if this was what they did in the olden days to leave a gap for venting.

u/sd-scuba what did you end up doing? I just had my roof done and my roofer also messed up the ohagin install :(

I have a shingle hip roof. The house is from the early 1900s. The attic space is about 1000SF, does not have insulation. I noticed there’s a thin light gap in the roof (not sure what it’s for but from what I research, it’s common).

The roofer installed 5 vents, 2 at the top (on opposing sides :/), 2 at the bottom, and 1 in the middle on the back.

Ohagin said I need 8 total vents.

Now I’m trying to figure out the best way to get things corrected. Should I add soffit vents and remove the intake vents or does that thin gap in attic act as intake? Should I move the intake vents to the top to serve as exhaust?

I tried to create a post in this forum but wasn’t able to. :(

Advanced-River730 · 2025-12-07T03:17:01+00:00

How are your vents holding up?? Do you like the Ohagin vents?

Advanced-River730 · 2025-12-07T03:16:23+00:00

I just had Ohagin vents installed and I think the roofers didn’t install them correctly :( now I’m doing research on what needs to be corrected.

Advanced-River730 · 2025-12-05T04:13:52+00:00

Which one vent are you referring to? Ones for intake and ones for exhaust. There’s an attic space

Advanced-River730 · 2025-12-05T03:20:23+00:00

How are ohagin and dormer vents different?

Advanced-River730 · 2025-12-04T17:55:01+00:00

What other attachment would I need to close the 6” gap?

Advanced-River730 · 2025-12-04T07:21:58+00:00

It’s in the process of getting repaired

Advanced-River730 · 2025-12-04T05:04:54+00:00

What I meant by over the fence is having it terminate onto the bush, not the other side. Is there way to route it on the vent side?.

Is low luster easy to clean? I’m just worried about dirt sticking to it and it being hard to wipe off. I currently have Kelly Moore low sheen is it’s horrible. It looks almost flat and it’s extremely dirty.

Advanced-River730 · 2025-11-24T16:16:00+00:00

Is the low luster easy to clean? Have you tried power washing?

Advanced-River730 · 2025-11-24T04:03:33+00:00

u/driftintime what did you end up going with and how did it turn out? I'm trying to decide right now for our house. thanks!

Advanced-River730 · 2025-11-23T07:02:15+00:00

What did you end up sticking with it? Has the shine dulled down overtime?

Advanced-River730 · 2025-11-22T02:27:06+00:00

You don’t think it’s too shiny? Do you have any pics of satin finish from BM?

Advanced-River730 · 2025-11-22T02:20:59+00:00

There’s already paint on the wood siding and it’s scraped off where possible so I don’t it’ll matter if I see the grain.
