Clearances
The Brentwood Insert is designed to be installed into a
masonry or a factory built zero clearance fireplace, or built in
with the optional Mirage Zero-Clearance Kit. The masonry
fireplace must be built according to the requirements of the
standards for chimneys, fireplaces, vents and solid fuel burn-
ing appliances, NFPA 211 (Latest Edition) or applicable
National, Provincial, State or local codes. The factory built
zero clearance fireplace and its chimney must be certified and
meet applicable National, Provincial, State or local codes.
The minimum clearances from the appliance to combustible
surfaces are shown on Fig. #5 and #6. Adequate clearances
around air openings and combustion air supplies are required.
