PLANNING THE INSTALLATION When planning on appliance installation, it is necessary to determine the following information before installing: • Where the appliance is to be installed. • The vent system configuration to be used. • Gas supply piping. • Electrical Wiring. • Framing and finishing details. • Hearth Protection Pad Requirements. • Whether accessories such as a wall switch, remote control, and ceiling fan are desired.
ROUGH FRAMING DIMENSIONS Rough Framing Dimensions The Rough Framing Dimensions must be maintained to allow this fireplace to slide into the framing cavity with a 900 elbow installed on the top starter collar. After the FV46 Fireplace is inserted into the rough framed cavity, install one 2x4 on each side adjacent to the side of this fireplace’s body and one 2x4 on top of the top framing standoffs to close the air gap and to act as nailing studs for finishing materials.
FRAMING DEPTH and FINISHING GUIDES The framing depth for this fireplace is 22-1/2 inches. This is a fixed depth required for all installations, except a corner installation and for installations that use solid Granite or Marble slabs as fascia materials. For corner installations, General Appliance Specifications and Planning The Installation sections in this Manual.
FINISHING MATERIALS INSTALLATION All finishing materials that surround this fireplace’s rectangle profile must extend out from the face surface of this fireplace 1 inch. Tiles and Faux Rock If installing Tiles or Faux Rock, first install a ½” thick (minimum) Cement Board (Hardibacker or Durock Brand) over the face of the fireplace and framing members. Follow by applying Thinset mortar (no polymer additives) using ¼” square notched trowel on the cement board surface.
HEARTH PROTECTION PAD REQUIREMENTS Hearth Protection R Rating: MINIMUM R-1 IS REQUIRED. USE OF A ½” THICK (MINIMUM) CEMENT BOARD (Hardibacker, Wonderboard or other brand) plus ¼” thick mortar (ThinSet type) plus ¼” thick ceramic tile exceed the R-1 requirement. Use this as a reference, if in doubt. Natural Stones of 1” or greater thickness also exceed R-1 rating. All hearth pads must be non-combustible (metal, brick, stone, or mineral fiberboard).
GENERAL INFORMATION Your Mendota Gas Fireplace has a state-of-the-art co-axial direct vent, sealed combustion system. This advanced and highly efficient system brings in outside air for combustion, has a separate exhaust vent and efficiently heats and re-circulates room air. The Mendota system maintains high air quality, maximizes efficiency and assures proper operation in today's "air-tight" homes.
on top of this fireplace will damage the 10 foot cable if you route the cable to the right side. GAS SUPPLY REQUIREMENTS Correct gas pressure and proper gas supply line sizing is imperative to the successful performance of your Mendota gas fireplace. Be sure the gas supplier or plumber carefully checks for correct gas pressure and gas line sizing when installing the fireplace. • • • • • It is critical to carefully check for gas leaks when hooking up the fireplace -- check with soap & water solution.
GAS PRESSURE REQUIREMENTS One of the main causes of operating problems with gas appliances can be improper gas pressure! Problems such as changes in flame color or configuration, gas pilot or burner outages, intermittent operation, changes in heat output, excessive burner noise, etc. are nearly always the result of changes in gas pressure or improper gas pressure at the time of the installation.
GENERAL 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.

VERTICAL THROUGH-THE-ROOF VENTING USING FOUR 900 ELBOWS In extreme situations, Four 900 elbows may be required to reach a proper exit point for the vent system. Mendota has spent considerable time and effort in the design of this fireplace and its venting system. Through this effort, Mendota has been able to certify the use of Four 900 elbows. The use of Four 900 elbows must meet some minimum prerequisites. Prerequisite #1: The vent system must terminate vertically using a vertical vent cap.
FV46 DOOR OPERATION TO REMOVE DOOR 1. Use the glass latch tool to disconnect the spring latches from the glass frame. Insert tool into hole in latch, pull towards you and Rotate 90 degrees to disengage top latches. Remove tool. There are two spring latches on top of this gas fireplace. 2. With both hands, rotate top edge of glass frame away from unit 12 inches. 3. Lift glass frame up 1 inch, at an angle, and move away from unit. 4. Door is now free from unit. TO REPLACE DOOR 1. 2. 3. 4. 5.
INSTALLATION CHECK OFF LIST Co-axial vent rigid pipe, wall vent cap or roof vent cap must be installed by a Mendota approved person in accordance with instructions. All joints must be secured, "twistlocked" and leak-proof. 1000ºF sealant must be used on the inner pipe joints of all DuraVent pipe sections. Horizontal or vertical vent cap must be installed "right-side-up" and tightly sealed to structure per instructions. Vent Caps must be Mendota approved.
FV46 LOG SET INSTALLATION INSTRUCTIONS FOLLOW EACH STEP DEPICTED IN THE DIAGRAMS, BELOW, TO INSTALL THE LOG SET. CAUTION: LOGS ARE FRAGILE, HANDLE LOG PIECES WITH CARE. Carefully unpack 14-piece log set and bags of coals & embers. NOTE: Logs are very fragile, handle with care. Coals must not block pilot or burner flame! Placement of coals has a big effect on front burner flame appearance and "glow" of coals. More coals = less yellow flame and more glow. Fewer coals = more yellow flame and less "glow".
