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 ab-
sence of local codes, the installation must conform with 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 Safety Standard, Title 24 CFR, Part 3280, or, when such a standard is not applicable, the

Note: For mobile home installations unit must be bolted to the floor and properly grounded.
1. After selection of the desired fireplace location (see pg. 3), prepare the rough opening using framing dimensions on
page 4. Prepare opening to allow for co-axial vent (see "Flue Venting Instructions" on
2. Check to make certain all venting requirements and locations are being followed. (See pg 8 -15).
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.
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 4 for specific details. 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 ma-
terial, 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 16 for specific details and exceptions. Rough framing can
come no closer to unit than the stand-offs.
5. 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 lagscrew fireplace to floor, if required.
NOTE: A removable panel in the enclosure for future visual inspection of the flue connection is recommended
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. 30 and "Electrical Requirements" pg. 3.
7. Have gas supplier or qualified plumber install gas supply line to fireplace and connect to gas nipple. Be sure gas
and plumbing instructions (see pgs. 6-7) and all local and national codes are carefully followed. Carefully 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
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 improved by
removing the upper Millenia grills, opening the Andover and Prairie Doors and opening the Wellington Screens.
HIGH ALTITUDE INSTALLATION INFORMATION: Prior to installing at altitudes higher than 7500, please con-
tact the Mendota technical service department for specific venting requirements and venting restrictions.
