VENT-FREE APPLICATIONS (Additional Requirements)
Fireplace Hoods (VENT-FREE)
A fireplace hood deflects heat away from the fireplace face and mantel, reducing the potential for heat related warping
or discoloration. The use of a fireplace hood is highly recommended. Fireplace Hoods are offered by many
leading fireplace manufacturers.
