Finishing Your Fireplace; Mantel; Glass Doors - Desa C36EMW Installation Instructions Manual

CHASE INSTALLATIONS
Instructions for chase installations are included with the chase
style termination chosen. In a multiple chase installation, be
sure to provide adequate distance between terminations to
prevent smoke spillage from one termination to another. We
suggest that terminations be separated at least 24 inches,
center to center and stacked at vertical height difference of 18
inches (see figure 18).
Figure 18 MULTIPLE CHASE INSTALLATION
10-FOOT RULE
All flue gas outlet of chimney termination must extend a
minimum of 3 feet in height above the highest point where it
passes through the roof and must be at least 2 feet above the
highest point of the roof that is within a horizontal distance of
10 feet (see figure 19).

FINISHING THE FIREPLACE
Combustible materials, such as wallboard, gypsum board,
sheet rock, drywall, plywood, etc. may make direct contact
with sides and top periphery of the fireplace face. It is
important that combustible materials do not overlap the face
itself. Brick, glass, tile or other non-combustible materials
may overlap the front face provided they do not obstruct
essential openings like louvered slots or any other opening.
When overlapping with a non-combustible facing material,
use only non-combustible mortar or adhesive.

MANTEL

A mantel may be installed if desired (see figure 20),
Woodwork such as wood trims, mantels, or any other
combustible material projecting from the front face must not
be placed within 9 inches of the fireplace opening (and within
6 inches of the top louver opening). Combustible materials
above 9 inches and projecting more than 1-1/2 inches from the
fireplace must not be placed less than 12 inches from the top
opening of the fireplace (NFPA STD 211, Sec. 7-3.3.3).

NOTE: HUD requirements may supersede these minimum
dimensions.
OPERATING GUIDELINES AND MAINTENANCE

GLASS DOORS

Glass doors are standard with the C36EMW fireplace. When
the fireplace is in operation, doors must in FULLY OPENED
or FULLY CLOSED position only or a fire hazard may be
created (see figure 21).
A fireplace equipped with glass doors operates much
differently than a fireplace with an open front. A fireplace
with glass doors has a limited amount of air for combustion.
Excessive heat within the fireplace can result if too large a fire
is built or if the combustion air gate is not completely open.
The following tips should be followed to assure that both the
fireplace and the glass door retain their beauty and function
properly. Both the flue damper and the glass doors must be
fully opened before starting the fire.
sufficient combustion air and maintain safe temperatures in
the firebox.
