INSTALLATION AND OPERATION INSTRUCTIONS ME43 43" Wood Burning Fireplaces P/N 850,027M REV. E 12/2007 MODEL ME43BK SP This installation manual will enable you to obtain a safe, efficient and dependable installation of your fireplace system. Please read and understand these instructions before beginning your installation. Do not alter or modify the fireplace or its components under any circumstances.
IMPORTANT! GENERAL SAFETY PRECAUTIONS. READ AND UNDERSTAND THESE SAFETY RULES BEFORE YOUR FIRST FIRE. WARNING Never leave children unattended when there is a fire burning in the fireplace. IMPORTANT When burning wood, use SOLID NATURAL DRY WELL-SEASONED WOOD ONLY. Hardwoods are recommended (soft woods tend to burn very quickly).
Congratulations! • This fireplace must be installed with Security In selecting this LENNOX™ wood-burning appliance you have chosen one of the finest fireplaces available. The ME43 wood fireplace is a clean burning fireplace that is designed to provide you dependable service as well as warmth and enjoyment for many years to come. Please carefully read and follow all of the instructions found in this manual. Please pay special attention to the safety instructions provided in this manual.
FIREPLACE MAINTENANCE Creosote When wood is burned slowly, it produces tar and other organic vapors which combine with expelled moisture to form a black deposit called creosote. The creosote vapors condense in the relatively cool chimney flue of a slow burning fire. As a result, creosote residue accumulates on the flue lining. When ignited, this creosote makes an extremely hot fire.
OPERATING THE fireplace Fuel The ME43 fireplace is designed to work best when fueled with seasoned cordwood. Hardwoods are preferred to softwoods since the energy content of wood is relative to its density. Hardwoods will result in a longer burning fire and less frequent refueling. A moisture content of 15% to 20% (seasoned) is preferred. Excessively wet wood will be difficult to burn and will result in lower efficiency and increased creosoting.
Failure to use LHP parts or conduct variations in techniques and construction materials described in this installation manual may create a serious fire hazard and may void the warranty and the WHI listing. 3. Always check your local building codes. The installation must comply with their regulations. Before beginning the installation, consult the local authorities and make sure your building permit complies with their requirements. 4.
Fireplace Facing WARNING DRYWALL PANEL OR EQUIVALENT The fireplace should be framed using 2" x 3" (50mm x 75mm) or heavier lumber. The top of the fireplace is not zero clearance. Do not place any insulating material in the space above the fireplace for a height of 7 feet from the base of the fireplace. 2" x 3" MIN. Figure 10 on Page 10 shows the general framing layout. Combustible materials must be installed flush with the fireplace facing. They may not project out in front of the fireplace.
Hearth Extension Requirements (refer to Figure 7) A non-combustible hearth extension must be built in front of the fireplace and extend out on both sides. Hearth extensions must be constructed according to the following guidelines: 1. A layer of sheet metal 0.018" (0.45mm) thick or 3/8" (9mm) thick insulating board or any other material (tiles, marble, granite) with equivalent heat resistance may be used.
Installation of the fan kit model UZY3 NOTE: The fireplace must be electrically connected and grounded in accordance with local codes or in the absence of local codes, with the current CSA C22.1 Canadian Electrical Code. For U.S.A. installations, follow local codes and the National Electrical Code ANSI/NFPA No 70. Note: This fan kit can easily be installed when the fireplace has a pre-installed junction box. You just have to plug them in.
Corner Installation 23-11/32” (593mm) Notes J D Due to Lennox' ongoing commitment to quality, all specifications, ratings and dimensions are subject to change without notice. 2" X 3" MIN. F All framing dimensions calculated for 1/2" dry wall at the fireplace face. If sheathing the chase or finishing with other thickness materials, calculations will need to be made. * The fireplace must not be in contact with any insulation or loose filling material.
central forced air kit The knock-outs provided on the sides of the ME43 fireplace allow the connection of insulated flexible pipe which enables you to heat adjacent rooms up to 50 feet from the fireplace. The ducting system must be installed as described below : 1. Fix the adaptor at the side of the fireplace by twist-locking the adaptor to the fireplace. You can use more than one outlet on the fireplace (Figure 11). 2. Attach the 5" flexible pipe, using the collars provided.
AC chimney should not be used in cold areas, where temperatures are likely to fall below 32° F (0° C), or altitudes above 4000 feet. Insulate joists Same As Ceiling A chimney venting a fireplace shall not vent any other appliance. Draft Stops The minimum system heights are indicated in Table 1. Firestop In altitude, add 18" (450mm) to the chimney for every 2000 feet (600 m) above sea level. CTDT Termination All chimney installations must include at least one support.
CHIMNEY INSTALLATION INSTRUCTIONS STRAIGHT INSTALLATION Cut and frame the holes in the ceiling, floor and roof where the chimney will pass (see Figure 16). Use a plumb-bob to line up the center of the holes. The hole sizes are indicated in Table 2 for the floor and ceiling holes and in Table 3 on Page 15 for the roof holes. From below, install a firestop in each ceiling/ floor separation through which the chimney will pass.

AIR COOLED ANGLED WALL RADIATION SHIELD (RSM+, RSMI30, RSMI45) CHIMNEY AC ACRS (RADIATION SHIELD) BRACE STRAPS When traversing a combustible wall with the chimney at a 30° or 45° angle, an angled firestop and/or wall radiation shield must be installed. Only one is required (Figure 22). Table 6 gives recommended hole size for installing a wall radiation shield. Note: 45° angle installation for Canada only.
UNIVERSAL ROOF SUPPORT INSTALLATION CHIMNEY CHASE AND MULTIPLE TERMINATIONS This support has three possible uses: 1. 2. 3. For ASHT+ and S-2100+ chimneys, it must be used on a roof to support the chimney. It may be used on a floor, ceiling or roof above an offset to support the chimney above the offset. It may be used on a floor, ceiling or roof as a supplementary support when the chimney height exceeds 15 feet (4.6 m.). Table 7 gives maximum height of supported chimney.
