The noncombustible finishing
material across the
top of the fireplace opening will
be even with the lower edge of
the metal face.

Noncombustible finishing
materials MUST overlap
side faces by 1 1/4 in. (32 mm)
to cover the edges of the
refractory. Finished opening
should be 38 x 50 in. (965 x
1270 mm) to allow for door
installation.

Mortar should be applied
after the finishing material
is installed. Mortar will be
applied between the
finishing materials and the
refractory edges, bottom
and sides.

The seam between the
finishing materials and
firebox top must be sealed
with a high-temperature
silicone sealant.

The surface of the finished hearth extension and

G. Install Screens

• Remove one screen rod by removing

one screw (near the center of the top
front). Pull rod out of the hole. Keep
the screw.

• Lay one screen panel fl at and slide the

round end of the rod through the rings
starting at the handle side of screen.
Leave the last ring off the rod.

• Insert the rod through the hole in the

bracket. Slip the last ring over the rod
on the other side of the bracket.

• Fasten

the

fl at end of the screen rod

back in place using the screw removed
earlier.

• Repeat for the other screen panel.

• Mix approximately 1/3 of the mortar material with 1/2

gallon of water in the mixing bucket. Stir the mixture with
the mixing attachment and drill. The consistency should
allow the material to be squeezed from the mortar bag but
not too runny.

• Fill the mortar bag with the prepared mixture.
• Apply mortar by squeezing the material from the mortar

bag into the joint lines. If fi lling a vertical line, start from
the top and work down. Apply slowly. Mixture should be
fl ush or higher than the refractory surface.

• Mix more material as necessary to fi nish the job and then

let the unit set until fi rm, may take two hours or more.

• Thoroughly clean the bag, tools and mixing bucket.
• Use a joint striker and strike the material in the joints. The

excess material should fall off somewhat dry.

• Sweep the loose material off the fl oor of the unit.
• Final cleanup with soap and water
• VERY IMPORTANT: Allow the mortar 72 hours to cure

before operating the fi replace.
