INSTALLATION INSTRUCTIONS

CAUTION: Each installation must conform to all local, state and national codes. Refer to the national fuel gas code and
local zoning and code authorities for details on installation requirements. The Mendota Fireplace must be vented to the
outside in accordance with the latest edition of the National Fuel Gas Code. In the absence of local codes, the installation
must conform to the most current edition of the National Fuel Gas Code ANSI Z223.1, also known as NFPA 54. NOTE:
The Mendota DXV Fireplace is approved for mobile home and bedroom installations.
CAUTION: The Mendota DXV Fireplace may be installed in a manufactured (mobile) homes after the first sale of the
home. Manufactured home (mobile home) installation must conform with the Manufactured Home Construction and Safe-
ty Standard, Title 24 CFR, Part 3280, or, when such a standard is not applicable, the Standard for Manufactured Home
Installations, ANSI A225.1/NFPA 501A, or CSA Z240.4-Gas Equipped Mobile Housing. Consult your local building offi-
cial. Note: For mobile home installations unit must be bolted to the floor and properly grounded.
1. After selection of the desired fireplace location, prepare the rough opening using framing dimensions on page 4.
Prepare opening to allow for co-axial vent (see "Flue Venting Instructions" on pgs. 13-21).
2. Check to make certain all venting requirements and locations are being followed. (See pg 13 -21).
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 accom-
modate the thickness of the wall material. NOTE: FRAMING MATERIAL ABOVE FIREPLACE MUST MAINTAIN
CORRECT CLEARANCES TO VENT PIPE.
4. Slide Fireplace into the rough framed opening. When finishing the unit, combustible materials may
overlay nailing flanges and come in contact with the side edges of the black front surface, but may
not overlay the 2" black surface. A 40-1/8" x 4" Top Screw Strip (part #HA-41-00015) is supplied with
the fireplace and must be installed on the top of this fireplace. The Top Screw Strip provides a 4"
clearance to combustible materials at the top of the fireplace. See Page 8 for specific details.
5. Combustible wall covering materials may only be installed down to the top flat edge of the Top Screw
Strip. Noncombustible boards such as "Dura-Rock" or "wonder board" can be installed on top of the
face of the Top Screw Strip and on top of the rest of the black face of the fireplace. Noncombustible
material, such as marble or brick, can be installed over the 2" black surface up to the inside edges of
black frame only if some Designer Fronts are to be installed. See Page 23 for specific details and ex-
ceptions. Rough framing can come no closer to unit than the stand-offs.
6. Level the Fireplace and secure into opening by nailing through the nailing flanges on cabinet side
panels. Holes are provided in fireplace floor behind grill to lag screw fireplace to floor, if required.
NOTE: A removable panel in the enclosure for future visual inspection of the flue connection is
recommended
7. Have an electrician install a 120 Volt supply to the junction box on lower left side of the fireplace cabinet. Con-
nect 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 and "Electrical Requirements".
8. Have gas supplier or qualified plumber install gas supply line to fireplace and connect to gas nipple.
Be sure gas and plumbing instructions and all local and national codes are carefully followed. Care-
fully check for gas leaks and for proper gas pressure.
IMPORTANT: Any safety screen, guard, glass, grill, pressure relief cap, etc. removed for servicing a fireplace/room
heater must be replaced
BLOWER OPERATION
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. 10 min.) and extended blower operation during "cool-down" of unit. (Approx. 1/2 hour).
OPERATION DURING POWER OUTAGES: This fireplace is designed to operate for a maximum 1-1/2 continuous
hours during power outages on HIGH FIRE. The blower will not operate, but natural convection can be improved by
removing the upper Millennia grills, opening the Andover and Prairie Doors and opening the Wellington Screens. If
burned on LOW FIRE (front burner only), this appliance may be run continuously indefinitely during power outages.
