Fireplace Facing
When selecting the finish material for your fireplace, it is important
to remember the following:
If the surround of the fireplace is to be painted to match the room decor,
heat-resistant paint must be provided . Also, decorative facing must
not extend past the fireplace opening at all, because it will interfere
with the access to retainers for removal of glass door and access to
the lower compartment.
Mantels & Surrounds
National Canadian Gas Association mantel test requirements are for
fire hazard prevention to combustible materials.
Please be aware; temperatures over the mantel will rise above normal
room temperature and walls above fireplace may be hot to touch.
