How much will these doors heat?

In actual tests the doors were rated at 30,000 BTU's per hour, enough to warm up to 1,000 square feet. Country Flame doors are one of the few, if not the only, fireplace doors with a heat rating.

Are there restrictions on the use of Country Flame Fireplace Doors?

Yes, they should not be installed on zero-clearance (pre-fab) fireplaces.

Can the Country Flame Doors be installed over stone?

Yes, the installer may have to fill some voids with insulation or masonry.

Will the Country Flame Doors allow my fireplace to hold a fire longer?

Yes. The doors are very tight and you will have the same type of control available on high quality stoves. Many users report fires that burn overnight, even up to 12 hours.

How do I control the fire?

The primary air controls at the bottom front of the doors on all models allow you to precisely meter the air into the fire. This control results in long and even burns.
