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

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.

The DXV Fireplace must be installed by a qualified Mendota approved service person.

1. After selection of the desired fireplace location (see PAGE 3), prepare the rough opening using framing dimensions

on PAGE 4 and 5. Prepare opening to allow for co-axial vent (see "Flue Venting Instructions" on PAGEs. 9 -18).

2. Check to make certain all venting requirements and locations are being followed. (see PAGE 9 -18).

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 edges of the black front surface, but may not overlay the 2" black surface. A

noncombustible board such as "Dura-Rock" or "wonder board" must be used within 4" of top black frame. Non-

combustible material, such as marble or brick, can be installed over the 2" black surface 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 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 PAGE 34 and "Electrical Requirements" PAGE 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 PAGEs 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 grill, opening the doors on Andover and Prairie Fronts and opening the Wellington Firescreen.

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.
