3. The Fireplace is designed to be installed into rough framing. The drywall will cover the adjustable nailing

flanges on the Fireplace sides. Before sliding the Fireplace into the framed opening, adjust the nailing flanges

to accommodate the thickness of the wall material. NOTE: FRAMING MATERIAL ABOVE FIREPLACE

MUST MAINTAIN CORRECT CLEARANCES TO VENT PIPE.

ANDOVER, BENTLEY, DEERFIELD or WELLINGTON TRIMS!!

4. Slide Fireplace into the rough framed opening. When finishing the unit, combustible materials may overlay

nailing flanges and come in contact with the edges of the black front surface, but may not overlay the 2" black

surface. Noncombustible material, such as marble or brick, can be installed over the 2" black surface,

lington Front is NOT going to be used as the optional trim

A removable panel in the enclosure for future visual inspection of the flue connection is recom-

mended

6. Have an electrician install a 120 Volt supply to the junction box on lower left side of the fireplace cabinet.

Connect wires to the duplex outlet. This duplex outlet is removable from outside of cabinet for easy wiring.

Make sure the outlet is properly grounded and that the installation conforms to all local and national wiring

codes. See "Blower Operation" below, Blower Wiring Diagram pg. 28and "Electrical Requirements" pg. 3

replaced

prior to operating the fireplace/room heater.

The Mendota DXV Fireplace is designed so the blower operates continually when main burner is on. The blower output can

be regulated with the rheostat (included). NOTE: There will be a time delay in blower operation during "heat-up" (approx.

1/2 hour) and extended blower operation during "cool-down" of unit. (approx. 1/2 hour).

The fireplace is designed to operate during power outages. The blower will not operate, but natural convection can be im-

proved by removing the upper Millenia grills, opening the Andover and Prairie Doors and opening the Wellington Screens.
