Zero Clearance Fireplace Installation
This insert may be installed in a masonry or factory built/zero
clearance (ZC) fireplace. When installing in a ZC fireplace,
the ZC grate must be removed and the ZC damper must be
removed or secured open. The ZC doors, screen, refractory
or masonry lining, baffles and smoke shelf may be removed
if necessary to install the gas insert. However, do not cut
or alter the fireplace components. The removal of any
parts to facilitate installation must not alter the integrity of
the inner or outer shells of the fireplace cabinet. Any parts
removed must be replaceable if the insert is taken out of the
fireplace or the fireplace must be clearly marked with the
metal label that states: "This fireplace has been altered and
is no longer safe to operate." The insert is designed to fit
into a ZC fireplace with a minimum firebox height of 17-1/4"
(438mm). To facilitate this the hood will need to be removed
and discarded
(Note: The screws should be replaced in the
insert body). Installation of the flue collar is removable (see
Flue Collar Connection).
If the factory-built fireplace has no gas access hole(s) pro
-
vided, an access hole of 1-1/2" (37.5 mm) or less may be
drilled through the lower sides or bottom of the firebox in
a proper workmanship like manner. This access hole must
be plugged with a non-combustible insulation after the gas
supply line has been installed.
The installer must mechanically attach the marking supplied
with the gas fireplace insert to the inside of the firebox of the
fireplace into which the gas fireplace insert is installed.
Log Set Installation
If logs are not installed according to the log installation
instructions, flame impingement and improper combustion
could occur and result in soot and/or excessive produc-
tion of carbon monoxide (CO), a colorless, odorless,
toxic gas.
The size and position of the log set is critical to achieve
a safe, reliable and attractive flame pattern. Any attempt
to use a different log set in the fireplace will void the war-
ranty and will result in incomplete combustion, sooting
and poor flame quality.
*Brick Panels are not offered for the Medina™ Gas Insert.
