Chimney & Fireplaces/silicia sand safe for this use



I recently purchased a Peterson gas log set and I was told by 3 different chimney people that the Drop inside the fire box was to much since my outside brick-hearth step was raised to high.  Instead of tearing down brick and rebuilding, the
The store whom I purchased the gas log set is going to put one layer of loose full size firebrick too raise the floor of my existing brick firebox by 2.5" and use Silica sand in-between the bricks etc. I will be using the burner log kit above the loose fire brick filled with Silica sand in the pan.
My question being will the gas fire effect the Silica sand that is also placed in-between and around the loose brick?

Thank you

Provided your fireplace and chimney is a site constructed masonry structure and it sounds like it is, what you described sounds like a great idea. No issues with the sand. I would have recomended the same fix. Something to think about, our industry standard requires an NFPA-211, level II inspection be performed prior to operation for safety. Use the links at the bottom of my home page at to find a qualified inspector in your area. Good luck.h
