Section 6: Finishing
WARNING!
We recommend careful consideration be given to the eects of elevated
mantel temperatures. In the case of candles, plastic, pictures, etc. these
temperatures may be in excess of the product design. This can cause
melting, deformation, discoloration or premature failure of TV, radio, and
other electronic components.
Figure 24. Combustible mantels and facings.
WARNING!
When covering the upper metal portion of the replace, up to 4" (as shown in
Figure 24) with a non-combustible material, the decorative facing materials
may be subject to temperatures in excess of 250° F. This should be considered
when selecting facing materials.
Finishing Around the Fireplace
Combustible mantels and moldings may be safely installed over the top and on the
front of the replace provided that they do not project beyond shaded area shown
in Figure 24.
Fireplace Facing
When sizing the nish material for your replace, it is important to remember that
THE OPENING MUST NOT BE OBSTRUCTED IN ANY WAY. To do so restricts the air
supply for the control compartments and heat exchanger. It also prevents
access for servicing controls.
The face of the replace may be painted to match the room decor, provided you use
a heat-resistant paint. Decorative facing must not extend past the replace opening
at all because it will interfere with the access to retainers for removal of glass door.
Figure 25. Installing the Nailing Flange Extension.
Installing the Nailing Flange Extension
Once the replace is placed into the rough framed opening, and the supplied steel
lintel is in place, (Part No. H42074) (see Figure 2),
The supplied nailing extension must be placed along the top edge of the replace and
securely fastened in place to the metal lintel, and combustible wood framing. Note:
The nailing ange extension can be substituted with a piece of non-combustible
material of the same size and thermal characteristics, i.e. cement board or equivalent.
