Over a year ago, i got a new Monessen KHLDV400 fireplace. Not sure who owns them anymore (it was Majestic and then Vermont Castings). Anyway the siding is melting and the dealer that installed it is unresponsive.

So I am trying to figure out , is the Vinyl siding standoff kit installed?

What can i do to fix this? I have heard some talk about a deflector. The siding has melted some.
I have also seen some pics on the internet of another termination kit that has no louvers on the top side, would that help or could i block off those louvers with a piece of metal.

Any help would be appreciated.

Please note: in 2 of the pics is the side of an aluminum extension ladder, in case you were wondering what that was.

thx

No it's not. The kit will bring the cap out another 3 - 4 inches from the siding...
This is what it looks like.

 
Thanks for the response . The cap i have now has outside dimension of 16x16. Will the cap go over the standoff box?
Do I need any more pipe? Can i do this all outside?
thx
 
Everything can be done from the outside.
You will have to remove the cap. Should be held in place with 4 screws.
Mount the standoff to the wall., but you won't know
if may need to extend the direct vent, until you see what's behind the cap.
There should be a slip (or an adjustable) section there, but it may not be long
enough to engage the slip section on the cap. Once you have the venting set
to the correct length, you slip the cap over the vent pipe & screw the cap to the
vinyl siding standoff.
 
ok, pulled off the cap, it is a 58DVA-HC.

There is some free play in the pipe that is there, maybe 3/4 of an inch. but not enough if I am gonna go out another 3-4 inches. What is the best way to extend the pipe, from the house side or the cap side?
Thanks for all your help.

From the house side, you have to twist lock a short section.
See if your installer has a 4" or 6" long piece of matching vent.
The cap should slide right over it, after you've installed the VSS.
 
Can i just order this to get the 3 inches?

 
That "slip" section will work just fine BUT....
I suggest you you test fit it on the
first section still in the wall.
Install the vinyl siding shield &
Slide the cap over the vent & seat it.
You need to insure that the slip you're
installing has minimum free play &
CANNOT separate in the wall.
If you're good, attach the cap to the VSS.
If there is ANY doubt in your mind,
that it MIGHT happen, attach the slip
to the vent cap with a couple of sheet metal
screws. 1/4" hex head "Zip" screws will work
perfectly & you can drive them in with your
screw gun.
 
I added the pipe length. i had to push it in all the way to test fit it. i have a minimum of 2 3/4 inch clearance between the termination cap and the house, adding a little more clearance will be easy. i just ordered the vinyl standoff box, may have to add a short stud to make it fit. i'' probably skip the screws the piece of pipe i added is well pushed into the existing pipe, can't ever see it coming apart. . thx for all your help
