Existing Fireplace Preparation

A few points must be considered before inserting the RF24 into an existing fireplace cavity. Generally, no 

modifications are allowed to the existing fireplace that will compromise the integrity of the existing fireplace. 

Components that are bolted or screwed on such as dampers or baffles may be removed to accommodate the 

installation of the RF24 engine. 

Cutting away any sheet metal parts of the existing fireplace to accommodate 

the installation of the RF24 is prohibited

. Check with local authorities if in doubt.

Clean Fireplace and Chimney

Have the chimney swept and the fireplace cavity including ash dumps and clean-outs cleaned before installing the 

RF24 heater and vent liners. Any creosote or soot residue remaining in the fireplace 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.

Existing Dampers

Factory-built, zero-clearance fireplaces will require the damper to be removed in order to install the vent liners. 

These dampers are usually bolted into place. Dampers in masonry fireplaces must be fixed open and may remain in 

place.

Ash Retaining Curbs

Some fireplaces (particularly factory-built) have a raised curb at the front edge to retain ashes. Check the 

dimensions carefully to ensure the RF24 engine will fit 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.

Gas Line Routing

Plan the routing of the gas line before proceeding. Utilize the existing hole for the gas line. If the factory-built 

fireplace 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 firebox. The access hole must be plugged with non-combustible insulation after the gas supply line 

has been installed. See General Dimension drawing for detailed location of gas inlet. Also, take into consideration 

whether or not a fan or shut-off 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 RF24 insert. Existing wire fire screens 

may remain in place or new ones may be added. The RF24 has been tested and approved to operate with wire fire 

screens in the closed or open positions.

Combustible Mantels

Combustible mantel clearances must conform to those required for the original solid-fuel fireplace into which the 

RF24 is being installed.

Paint Existing Refractory Liners

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

once installed.

Attach Warning Label to Existing Fireplace (label supplied loose with RF24 heater)

Attach the “This fireplace has been converted...” label to the existing fireplace using screws or other mechanical 

means and store any removed parts in back of the existing fireplace for future use.
