MASONRY INSTALLATION (Continued)
Step #2 - Concrete Block
Foundation.
The concrete foundation is used
support the weight of the
masonry column around the
fireplace. See the illustration on
page 8 for a cross section.
U.B.C. requires 8" side wall and
8" rear wall. Where Bldg. Codes
permit, a 4" masonry wall is
sufficient.
Step #3 - Masonry Hearth and
Fireplace Placement.
The masonry hearth is now
ready to be constructed. It must
extend a minimum of 18" from
the front of the fireplace. When
placing the fireplace on top of
the finished hearth, double
check its alignment and make
sure it meets all of the
specifications. At this time the
blower can also be placed in
position (See Step 4 for details).
The blower need not be directly
adjacent to the fireplace as it
appears to the right. Make sure
to run the electrical conduit that
provides the electrical power to
the fireplace out of the masonry
at this time. The other conduit
goes directly to the blower.
