The permit states "Dual-sided wall furnace. This is one side.
For many years the installation instructions included hallways along with traffic areas. My Dept assumed the position that a hallway is required to be 36" wide. Therefor if the wall furnace did not reduce the width of the hallway below 36", it was not in the hallway. I know, I know it sounds sorta off the mark. ( I am being nice here)
Screw that, this is my website. It is a stupid policy. But it gets worse. Now the hallway can be reduced below 36". I haven't seen anything in writing but some recalcitrant contractor complained to management and got his installation approved at 31".
So what to do. I know what I do. Your take on this may be different.
At the first inspection of the wall furnace the stud bay had not been opened up. When I told the contractor that the wall finish had to be removed he wanted to know why. One of the things that I mentioned was the plate spacer strap. This is the second inspection and there is a wrong plate spacer strap for a first floor plate line. (it must be wide open)
The sticker was removed from another section of vent and placed here. That's because I ask for the sticker to be visible.
I have never seen it done like this before and I probably never will again.
This is the third inspection and the contractor became vocal about my poor inspection skills.
The job is a reroof. I was there to inspect the sheathing. I noticed something shiny. I always notice shiny things. The roofer told me that he removed the transite vent because it was crumbling. He went to HD and bought a B vent which he crammed down the hole. That's got to cost extra. The contractor has a B license so he took out an electrical permit to replace a living room recepytacle and a plumbing permit to replace a bathroom faucet. I explain the reason for that somewhere else in this website. I voided the permits. I told him to send in a C-39 contractor to obtain a building permit for the re-roof and a C-20 to fix/replace the wall furnace.
The header plate is upside down. Drywall screws were used.
Trash like this. Notice the button board. In years past that would call for a sheet metal shield.
Look at that sheet metal. Think about it for a moment. Picture children playing. If you didn't get a chill you need to chill.
This shield was made from foil backed paper
Vertical support is a must have.
A permit was obtained to insulate the attic. I asked for a factory built insulation dam.
The damage that they cause to the roof when replacing the jack..... Well it can be serious.
The installation instructions state that carpet is not allowed under a wall furnace. I suppose that if it can light your clothes on fire, carpet is not out of the question. I think another concern is molten metal dripping on the carpet.
This was their best effort
At the first inspection there was no ladder so I did not look in the attic. I could tell that there was no attic shield. The correction stated "Install an attic shield". The contractor called and asked what an attic shield is. In my explanation I mentioned insulation as in "it keeps insulation away from the vent".
The purpose of the shield is to prevent stuff from falling into the stud bay and landing on top of the scary damned dangerous appliance.
The gap on the right resulted in a correction.
The other side is in an alcove that has no wall finish...or clearance.
That's was wide open as it gets because it hits the bottom plate.
Not to be outdone, this contractor installed the entire vent upside down.
Who would want this?
On this side the cover opens all the way. But it hits the valve and the valve can't be operated.
Getting back to attic shields. This is close to what it should look like. The shield is made to fit oval vent, not round vent.
It is "B" vent and shall be secured 1" away from combustibles. It's always nice if it exits the roof somewhat plumb.
There's a lot more that's wrong with this furnace. I called the contractor to tell them to shut this thing off. The contractor answers the phone with "We are a proud Home Depot Contractor". "This call is being recorded for training purposes". I bet that they save the recording. The contractor called back. He talked with the manager and I was replaced.
Enough in the attic.... how are they doing inside the dwelling. The installation instructions for a wall furnace tell you to warn old people and children. That's because old people and children have thin skin and burn easily . For the rest of us the warning is that this thing can light your clothes on fire. How they are able to sell these at all baffles me, well there are the warnings. Another of which says to not place the furnace in a traffic area.
This is an attic shield. It is upside down.
Contractors never provide a ladder to see inside the attic. Trust me on this, it is universal, it happens every time. I have talked to several contractors about that and I am told that there is nothing to see in the attic. I am told that I am the only inspector that asks to get in the attic. While I know that many inspectors do ask for a ladder, many do not. Too many and the number should be none.
This picture is all that you need to see. I found it because I did get into the attic.
I am used to seeing this. Of course the vent should not be smothered in tar. I figured that the roof jack must be shot. I would ask them to replace the jack. They did it. At the next inspection the jack was covered in tar. They do it to all of them, new roof jacks and old roof jacks alike.
Wall furnaces do not get the respect a scary damned dangerous appliance deserves.
