Draft Hood

[Darren]

What, if anything would you say about this?

I've seen this installed where the opening is on the bottom at a rear venting unit, but not this.

Thanks

I think it is rotated 90 degrees from the proper orientation, and not enough vertical distance above the boiler before running horizontal.

I also believe it's intended to b used on a rear vent appliance in a vertical position. But I found this as well https://i.ytimg.com/vi/O1o8XRLBJQo/0.jpg

I can't recall having ever seen that style draft hood on a gas-burning appliance - only oil. And even then it's sideways. When the boiler hasn't fired in a while and the air in the chimney is cold, that thing is going to spew gas exhaust like a firehose.

On another note, do you often see pilot lights tapped before the gas shut-off valve? We only see that on really ancient installations - like pre WWII. Never on an installation as recent as this.

Jim's comments made me look at the photo again. I looked at a larger image and it looks like the front inside panel is rusted through. That usually means that the combustion chamber liner/heat shields or the furnace cement between boiler sections have failed and water vapor from combustion is saturating the insulation. May be time for a new boiler.
