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 cur-

rent 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) home after the first sale of the home. Manu-

factured 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 Standard for Manufactured Home Installations, ANSI A225.1/NFPA

501A, or CSA Z240.4-Gas Equipped Mobile Housing. Consult your local building official. Note: For mobile home installations unit

must be bolted to the floor and properly grounded.

After selection of the desired fireplace location, prepare the rough opening using framing dimensions on PAGE 164.

Be sure to also prepare opening to allow for co-axial vent (see "Flue Venting Instructions".

2. Check to make certain all venting requirements and clearances are being followed.

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 MATERIALS LOCATED ABOVE FIREPLACE BODY MUST

MAINTAIN CORRECT CLEARANCES TO VENT PIPE.

DO NOT COVER THE 2" BLACK FRONT SURFACE OF THIS UNIT IF YOU INTEND TO USE THE 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 overlap the 2" black front surface.

Noncombustible material, such as marble, stones or brick, can be installed over the 2" black surface, only if you

are certain that a Deerfield Front, Andover Front, Bentley Front, Prairie Front or a Wellington Front is NOT

going to be used as the optional trim, up to the inside edge of black frame (next to glass). 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 secure fireplace to floor using lag screws or drywall screws, if required.

NOTE: A removable panel in the enclosure for future visual inspection of flue connection is recommended.

6. Have an electrician install a 115-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.

7. Have gas supplier or qualified plumber install gas supply line to fireplace and connect to gas nipple. Be sure Gas

Supply Requirements (see PG. 9-10) and all local and national codes are carefully followed.

IMPORTANT: Any safety screen, guard, glass or grills removed for servicing a fireplace/room heater must be replaced

prior to operating the fireplace/room heater.

The blower output can be regulated with the remote transmitter. NOTE: There will be a delay before the blower oper-

ates, in thermostat mode, during "heat-up" (approx. 10 minutes) and extended blower operation during "cool-down" of

unit (approx. ½ 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 grill and opening the screen doors (depending on the type of optional front installed).
