Finishing Around the Fireplace

Combustible mantels and mouldings may be safely installed over the
top and on the front of the fireplace provided that they do not project
beyond shaded area shown in Figure 18.

Fireplace Facing

When sizing the finish material for your fireplace, it is important to
remember the following: 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 fireplace may be painted to match the room decor,
provided you use a heat-resistant paint. Decorative facing must not
extend past the fireplace opening at all, because it will interfere with
the access to retainers for removal of glass door.

Installing the Nailing Flange Extension

Once the fireplace is placed into the rough framed opening, and the
supplied steel lintel is in place, (Part No. H38074) (see Figure 2),
Figure 20. Installing the Nailing Flange Extension.
The supplied nailing extension must be placed along the top edge of
the fireplace and securely fastened in place to the metal lintel, and
combustible wood framing. Note: The nailing flange extension can be
substituted with a piece of NON-Combustible material of the same size
and thermal characteristics, ie: cement board or equivalent.
We recommend careful consideration be given to the effects of elevated
mantel temperatures which may be in excess of product design,
for example: candles, plastic or pictures. This can cause melting,
deformation, discolouration or premature failure of T.V. radio, and other
electronic components.
When covering the upper metal portion of the fireplace, up to 4" (as
shown, Fig.19) with a non-combustible material Please Note: The
decorative facing materials may be subject to temperatures in excess
of 250° F. This should be considered when selecting facing materials.
Glass doors on gas fireplaces are extremely hot while the fireplace is on and
remain hot even after the fireplace has been turned off. Safety screens are
available and can reduce the risks of severe burns. Please keep children away
from the fireplace at all times.

Do not use ammonia based or abrasive cleaners on the glass, they will permanently
etch the surface. Use an approved gas fireplace glass cleaner such as Kel-Kem or
White off.
