MASONRY FIREPLACE

Before the installation the entire fireplace system
should be inspected for condition and code
compliance prior to connecting to the fireplace chim-
ney. Older fireplaces and chimneys may not have
been constructed to current-day codes.
The fireplace and chimney should be in, or brought
up to, acceptable conditions and proper clearances
should be met before connecting to the fireplace
chimney.
The size of the flue must be considered. If the
fireplace chimney is too large, a relining system may
be installed using an approved relining system.
