i've searched and i cannot the answer to this question. when using sheet metal to fabricate a heat shield , does it matter if the metal is galvanized ? i know galvanized pipe is a no-no. i will not use the shield to reduce clearances [not allowed on my stove in the USA - according to the manual] , this will only be an extra precaution.
 
galvanized is fine. be sure to use standoffs (or a couple layers of durock strips) to create at least a 1" air space behind the metal and keep it open at the top and bottom for good air circulation.

Here are some photos of a heat shield I made for the bottom of my VC defiant. Aluminum picture frame and aluminum sheet metal. Sits about 1/2 way from the bottom (3 1/2") of the stove and is very effective.

I had the material already so the cost was time and labor. :coolsmile:

Do you know of another one of those elsewhere. What I need is one that is basically four panels and not just three panels. Ideally it would be four panels the same size.

Thanks!

A sheet metal shop can bend you one up quickly.
 
The shield will be about 6" behind the stove at the rear,where I may use the pieces of Micore 300 left over from making the floor protector and about 12"on the sides. I was already aware of the need for spacers. remember , I am not decreasing the clearances to combustibles-my manual states 6" with doublewall pipe, I have set the distance to 8". I am using the heat shield as extra protection. My son works for a sheet metal shop. he can get me the metal at a discount, but they only have galvanized.

Always better safe than sorry, but just curious as per why you think you need the extra protection? In our case our VC Defiant didn't have a bottom heat shield nor fire brick at the bottom of the box and the tile under the stove got extremely warm. It was hot enough that I could barely keep my hand on the tile. Craig (owner of H dot C) suggested the idea of the heat shield to me and it has worked out great. :coolgrin:

Just curious,
Jim & Kathy

Galvanized should be fine in this application, it's not a fire barrier. Have your son hem the edges and spray it with some hi-temp paint to dress it up a bit.

My son and I had already decided to hem the edges to protect people [especially the grandkids-4,7,8 yrs. old] from cuts. Thanks guys-still waiting to hear from the manufacturer.

Jim & Kathy[/quote] I have always leaned a bit to the overkill side of things-just want to be sure it's safe.

Nothing wrong with overkill.... good luck with the project. Let us know how it turns out.
