Hey guys just got handed a custom house first one in a while. I have two problems. First is I need to sidemount plugs 4 inches above the floor. I know that 2 2x4s gives me 3 inches. What can you guys sugest for the extra inch. Or should I use something else. The other problem I have is everything in the cieling needs to be in a firebox. Cans are easy Ive got some firebox cans gotta love em. The question is how do you guys build fireboxs around exhaust fans. Thanks for your help guys.
 
Re: need some tips

How about 2 2x4's and 2 scraps of 1/2 inch plywood (usually plenty of scrap laying around.You are saying 4 inches but did you allow for the plate cover ?

Re: need some tips

Shocked, putty pads are not listed for this use, go to this page for more info.

Southernboy, build a 5/8" sheetrock box over the fan, in otherwords, five side the fan.

Re: need some tips

How many receptacles are going in the baseboard??

We do this in every house. Some just in Dining Room, some get all on the whole first floor.

If it's more than one room, you might want to use a box with bracket.

Also, you could cut 1 2x4 for each box and toe-nail it in at the height you need.
This would probably be quicker than cutting all of those other pieces.
 
Re: need some tips

Don't forget to hold the box out the depth of drywall plus the depth of the baseboard. Typically this is inch and a quarter.

Otherwise, you'll need to use box extentions.

Southernboy:

For your first problem, try these.

Make a 4" spacer, mark it so you know how far out from the face of a stud you need to place the front of the box, and use it to locate the box while you run the screws in. You can set them all in no time. Make sure you understand how the drywall and baseboard will be installed to get the spacing correct. However if you need to move the box in or out after the fact it's easy to do.

SB#2 - why is this your work? Seems like carpenter work to me.

But having been burned (NPI) too many times on this - be careful. What is the time rating req'd? 1/2, 1, 2 hours? If you use putty pads, do they give you the time rating you need? Also be careful with sheetrock. 5/8" firecode sheetrock WALLS built to UL standards work, but the same assembly cannot be used in a ceiling application for the same time rating. Look at the UL Orange Book.

I know I'm not being helpful, but if there was ever a fire, then they (the insurance co. lawyers) are going to start looking at this stuff, and you'll be wishing you walked away...

On the spacer, why not just cut a couple 4" lengths of 2x4" and use 'em the other way?

Roger:

How would you run the pipe from the exhaust fan to the outside?? Does it need sheet rocked around also?? Or do you use metal pipe and just run it through your 5 sided box??

Just curious.

Re: need some tips

Think about this: 4 inches off the floor.
What are we talking about. 4 inches to center. 4 inches to the bottom of the cover plate. First off are we talking about 4 inches off the finished floor. If so, what is the floor finish. The first thing to do is find out exactly what they want and make a template so that all measurements are the same. It really shows up when they put receptacles in the baseboard. If you are off a quarter of an inch it can be seen.
 
Re: need some tips

Steve, we would leave this to the mechanical contractor, so I'm definitely not well versed in this.

However, most of the exhaust fan ducts I see in rated ceilings are ridgid and of a pretty substantial gauge, there are also fire dampers in most if they travel through certain areas of a building on the way to the exterior.

I do know that there are listed class "0" and class "1" flexible ducts that are connected to fans in some cases, as to what determines their use, I don't know. :(

Very true. As a follow-up to my comment to "Make sure you understand how the drywall and baseboard will be installed to get the spacing correct" I would add that you need to make sure everyone understands what the final result will look like. Having a receptacle perfectly centered in the baseboard doesn't look all that great after they come around and apply some quarter-round at the bottom.

A fire damper would make sense. I just couldn't figure out what good it is to build a fire box with a hole in the middle :D
 
Re: need some tips

First off let me say thanks for the great tips already coming in. As for the fire rating on the fart fans. My boss told me that Ill have to 5 side em so I guess now Im an electrician that frames and hangs drywall. Heck Ill probaly mud the joints to make em look good. But seriously I have to drill out the holes in the drywall for the duct and wire then fire caulk around them. As for the plugs at 4 inches Ill probaly at this point in time run with Mr walkers suggestion of 2 sheets of plywood and 2x4s. I will keep in mind all suggestions of getting specs for the crown molding to make it have that bang effect. thanks again. Maybe Ill even post some pictures of the job.
 
Re: need some tips

Southern,

We just went thru this on a big 4 mill custom.After weighing out the time it takes to gather the "framing" materials , cut them to size and nail in place we went for old work plastic boxes to be installed after the base is up. We first met with the mill work installer who agreed to cut our old work opening into the base were we left our romex stapled out. so far the system is working out real good.
Also be careful were you run your wires near the crown moulding some of it can extend out pretty far and they shoot a lot of nailsinto it..

good luck

Kelley
