Are you burning real wood or is this a gas log set?

It's a gas log set.

yeah, its been a while since I used gas logs, but I believe gas log sets usually come with embers and sand. Also, you should be able to purchase these items separately at any fp store.

The sand helps distribute the flame along with the embers they add realism to your fire.

I put sand in my gas fireplace and now it seems the silica sand wont let the gas come out and it wont light

I wouldn't put sand in unless the fireplace manual says to do so. We have a gas fireplace that has the gas outlet holes on the bottom of the unit. The expert at the local fireplace store said that we should only use vermiculite to simulate glowing coals but to be careful NOT to cover the gas holes. Our daughter has a different model of fireplace and the manufacturer specifies using sand. However her's is designed to hold sand in a sand pan. I believe her gas outlets are also designed differently. Talk to an expert.

This really depends on whether they are wood burning fireplaces with gas logs, or actual gas fireplaces. If they are wood burning fireplaces with gas logs, it will depend on the type of burner system and whether they are vented or ventless sets. If it is a gas fireplace, not capable of burning wood, the answer is likely no.

So, we need to see pictures of the fireplaces before we can make a accurate recommendations. Any advice without seeing pictures can be bad advice or unsafe.
