Suitable Paints and Sealant Materials

3.2.12.4.1 Paint Types Approved for Use

Industrial Acrylic Paints, Alkyd based Paints. When selecting paint for applications on facings, mantels, corbels or floors within
2' in front of a fireplace raised 6" or higher, avoid off the shelf paints which may have modifier additives used to increase
"hiding" ability, accelerate drying times and curing times. Consult with a reputable paints and sealants supplier and acquire
industrial acrylic paints or alkyd-based paints.

3.2.12.4.2 Sealants Type Approved for Use

Heat resistant polyurethane sealants which are not damaged by prolonged exposure to raised temperatures. Many are flame
resistant, meaning that they resist ignition when exposed to high temperatures and can insulate the substrate and delay
damage to it. When selecting polyurethane for applications on facings, mantels, corbels or floors within 3' in front of or above a
fireplace, avoid off the shelf urethane sealants which may have modifier additives used to accelerate drying times and curing
times. Consult with a reputable paints and sealants supplier and acquire heat resistant polyurethane sealants.

3.2.12.4.3 Wood Application Cautions

If wood used around or in front of the fireplace has been chemically cleaned or bleached prior to staining or painting, it is of the
utmost importance to make certain that the cleaner or bleach does not remain in the wood substrate under the final paint or
sealant applied. If any cleaner or bleach remain within the wood structure, application of heat from the fireplace, even low-level
heat, will cause the cleaner or bleach compounds to expand or evaporate causing separation of the paint or sealant from the
wood surface and may cause peeling or bubbling of the paint or sealant.
Moisture content of the wood substrate is also of critical importance. High moisture content wood when heated will yield
evaporation of the moisture and hydraulic pressure under the paint or sealants which can lead to peeling or bubbling. Always
select the lowest moisture content wood substrate.

FRAMING DEPTH and FINISHING GUIDES
This fireplace comes with one standard finishing guide that will be used with any inside finish decorative front. Grace fronts
have optional finishing applications depending on what wall finishing material and what finished look you want to achieve. Refer
to the Grace finishing guide options.
It is important to know what wall finish is being used and what finish option is preferred prior to unit installation when choosing a
Grace front.
When the wall finish material will exceed 2 ½" in depth, the Grace (Option 3) guide kit will be required to allow the decorative
front to install properly.
All finish guides, standard or optional, protrude 1" from the face of the unit. Factory guides are installed with rivets and can be
removed with a ⅛" drill bit.
The finish guide used should be permanently left in place.
