Existing Fireplace Preparation
A few points must be considered before inserting the RF24 into an existing replace cavity. Generally, modications to
the existing replace that will compromise its integrity are NOT allowed. Components that are bolted or screwed on,
such as dampers or bafes, may be removed to accommodate the installation of the RF24 engine. 

Have the chimney swept and the replace cavity including ash dumps and clean-outs cleaned before installing the
RF24 heater and vent liners. Any creosote or soot residue remaining in the replace cavity chimney or clean-out may
cause odors or stains once the RF24 insert is installed. Consult with chimney sweep for information on how best to
clean.

Factory-built, zero clearance 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 replaces must be xed open and may remain in place.

Some replaces (particularly factory-built) have a raised curb at the front edge to retain ashes. Check the dimensions
carefully to ensure the RF24 engine will t behind any raised curb (some curbs may be removed separately from the
refractory base). The fret retainers allow for some vertical adjustment of the cast iron fret should the fret need to sit on
top of the curb, otherwise the fret will need to be eliminated or adequate room provided behind the curb.

Plan the routing of the gas line before proceeding. Utilize the existing hole for the gas line. If the factory-built replace
has no access hole, carefully drill an access hole of 1-1/2 inch (38 mm) or less through the lower sides or bottom of the
rebox. The access hole must be plugged with non-combustible insulation after the gas supply line has been installed.
See illustration in Dimensions section for detailed location of gas inlet. Also, take into consideration whether or not a
fan or shut-off valve will interfere when planning the routing of the gas line.

It may be desirable, for visual reasons, to paint the existing refractory liners in black to blend in with the RF24 insert
