Existing Fireplace Preparation
Existing Fireplace Preparation
A few points must be considered before inserting
the 700 into an existing
fi
replace cavity. Generally, no
modi
fi
cations are allowed to the existing
fi
replace that
will compromise the integrity of the existing
fi
replace.
Components that are bolted or screwed on such as
dampers or ba
ffl
es may be removed to accommodate
the installation of the 700 engine. Cutting away
any sheet metal parts of the existing
fi
replace to
accommodate the installation of the 700 is prohibited.
Check with local authorities if in doubt.
Clean Fireplace and Chimney
Have the chimney swept and the
fi
replace cavity
including ash dumps and clean-outs cleaned before
installing the 700 heater and vent liners. Any creosote
or soot residue remaining in the
fi
replace cavity
chimney or clean-out may cause odors or stains once
the 700 insert is installed. Consult with chimney sweep
for information on how best to clean.
Existing Dampers
Factory-built, zero-clearance
fi
replaces will require
the damper to be removed in order to install the vent
liners. These dampers are usually bolted into place.
Dampers in masonry
fi
replaces must be
fi
xed open and
may remain in place.
Ash Retaining Curbs
Some
fi
replaces (particularly factory-built) have a
raised curb at the front edge to retain ashes. Check the
dimensions carefully to ensure the 700 engine will
fi
t
behind any raised curb (some curbs may be removed
separately from the refractory base).
Gas Line Routing
Plan the routing of the gas line before proceeding.
Utilize the existing hole for the gas line of the factory-
built
fi
replace.
If the
fi
replace has no access hole, carefully drill an
access hole of 1.5 inch (38 mm) or less through the
lower sides or bottom of the
fi
rebox. The access hole
must be plugged with non-combustible insulation after
the gas supply line has been installed.
See Dimensions section for detailed location of gas
inlet. Also, take into consideration whether or not a fan
or shut-o
ff
valve will interfere when planning routing of
the gas line.
Existing Glass Doors and Wire Screens
Existing glass doors must be permanently removed
prior to installing the 700 insert.
Combustible Mantels
Combustible mantel clearances must conform to those
required for the original solid-fuel
fi
replace into which
the 700 is being installed.
Attach Warning Conversion Plate to Existing
Fireplace
(plate supplied loose with 700 heater)
Attach the “This
fi
replace has been converted...” label to
the existing
fi
replace using screws or other mechanical
means and store any removed parts in back of the
existing
fi
replace for future use.
