Desa C36EMW installation instructions Chase Installations

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).

Figure 19 10-FOOT RULE

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

INSTRUCTIONS

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. This will provide sufficient combustion air and maintain safe temperatures in the firebox.
