INSTALLATION AND OPERATION INSTRUCTIONS Ladera™ EPA Wood-Burning Fireplace P/N 506023-03 REV. A 11/2008 TM MODELS Ladera-BK Ladera-BN 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 THE FIREPLACE MUST BE OPERATED WITH THE DOORS FULLY OPENED OR DOORS FULLY CLOSED. IF THE DOORS ARE LEFT PARTLY OPENED, GAS AND FLAME MAY BE DRAWN OUT OF THE FIREPLACE OPENING, CREATING RISKS OF BOTH FIRE AND SMOKE. IF THE UNIT IS OPERATED WITH THE DOORS FULLY OPENED, THE FIRE SCREEN MUST BE USED.
Congratulations! OPTIONAL EQUIPMENT Order Separately - See Pages 22 and 23 In selecting this Lennox Hearth Products wood-burning appliance you have chosen one of the finest fireplaces available. The Ladera™ fireplace is a clean burning EPA certified high efficiency 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.
Building a Fire (starting and maintaining a fire) Note: Leave 1/2 inch of ashes at the bottom of the firebox. To start a fire, place several crumpled up balls of newspaper in the firebox. Place small dry pieces of kindling on top of the paper, criss-crossing the kindling so that there are air spaces in between. Keep the fuel far back enough so that air can get underneath. Open the air controls fully and light the newspaper. Once the newspaper and the kindling is well ignited, close the door.
A. Negative pressure in the house As the fire burns, air goes up the chimney. This air must be replaced through leakage into the house or through the outside air duct (optional). When operating the Ladera™ fireplace, open a nearby window temporarily to check if there is adequate replacement air supply. B. Fans operating (e.g.: range hood) These fans draw air out of the house and may actually cause a negative pressure in the house.
DISPOSING OF ASHES Note: For better performances, we recommend leaving 1/2 inch of ashes in the firebox. Remove ashes only when the fire is out and the ashes are cold (48 hours after the fire is out). WARNING Disposal of Ashes: Ashes should be placed in a metal container with a tight fitting lid. The closed container of ashes should be placed on a non-combustible floor or on the ground well away from all combustible materials, pending final disposal.
Glass Care Gasket Replacement Glass Replacement The glass used for the Ladera™ fireplace is a high temperature ceramic glass (1,400° F / 760° C). If the glass breaks, it must be replaced with an identical ceramic glass. Tempered glass or ordinary glass will not withstand the high temperatures of the Ladera fireplace. Replacement glass should be purchased from a Lennox Hearth Products dealer (see “Replacement Parts”, Page 24). DO NOT OPERATE THE UNIT WITH CRACKED OR BROKEN GLASS.
Optional Cast Facade installation Install the Facade per instructions provided in Facade Kit (ordered separately - see Page 22). Framing, Facing And Mantel The construction of the framing, facing, and mantel must be in accordance with the standards and the following illustrations (Figures 8 and 9): A. Frame the fireplace using 2” x 3” or heavier lumber. The crack between the fireplace and the hearth extension must be sealed with a non-combustible material such as sand-cement grout. B.

Figure 9 Opening 6’ 8” (2 m) Min. 1. Combustible material must be installed flush with the fireplace. It may not project in front of and on the fireplace (i.e. the steel facade of the fireplace) (Figure 10).
Once the repair is done, it is mandatory to apply a new high temperature black cement (Mill-Pack, available from your retailer) sealing the access plate and all screw holes. Because the Ladera fireplace is an air tight fireplace, failure to do so will reduce fireplace efficiency. Tightly screw the access plate back on place and reinstall the bottom refractory. Only non-combustible material should be superposed or projecting over the front of the fireplace.
Central Forced Air Kit Rain Cap Note: Not tested under EPA certification. If installed, this appliance no longer qualifies for EPA certification. Flashing Collar Flashing The knock-outs provided on the back and on the sides of the Ladera™ fireplace allow the connection of insulated flexible pipe which enables you to heat adjacent rooms up to 50 feet from the fireplace hot air outlet.

Adaptor Insulated Flex Pipe Figure 17 Insulation Flex 5” Diameter Aluminum Tape Blower Tightening Collar Figure 18 OUTSIDE AIR KIT (fireplace and AC chimney) The outside air kit is optional on the Ladera™ fireplace, but mandatory on the AC chimney. It can be burned drawing air only from the house. When the fireplace is in operation with the door closed, it will pull only a slight amount of air from the house.
Outside Air Installation THE CHIMNEY SYSTEM The outside air assembly may be installed according to the following requirements: A) Duct length should be kept to a minimum. The maximum length of a 4” interior diameter (100 mm) insulated flexible duct is twenty (20) feet (6.1 m). (See note below). B) The air intake register must not be installed more than ten (10) feet (3050 mm) above the base of the fireplace. C) The fresh air must come from outside the house.
CHIMNEY INSTALLATION INSTRUCTIONS 1. Cut and frame the holes in the ceiling, floor and roof where the chimney will pass (see Figure 23). Use a plumb-bob to line up the center of the holes. The sizes are indicated in Table 2 for the floor and ceiling holes and Table 3 (Page 16) for the roof holes.

OFFSET CHIMNEY INSTALLATION Chimney AC Support ACRS Starter Section Straps Straps Note: This illustration is not to scale. It represents how the chimney must be supported. A 30 degree offset only is allowed in the USA and a 45 degree maximum offset is allowed in Canada.
ANGLED WALL RADIATION SHIELD (RSM+ and RSMI30) Insulated Wall When traversing a combustible wall with the chimney at a 30º or 45º angle, an angled firestop or wall radiation shield must be installed. Only one is required. Note: 45º angle for Canada only (RSMI45) In cold climate locations (climates where temperatures will fall below 32° F / 0° C), we recommend that you use the insulated wall radiation shield since it will maintain the home’s thermal barrier.
CHIMNEY SUPPORT INSTALLATION Universal Roof Support 18” (460 mm) This support has three possible uses: 1. For ASHT+ / HT6103+ and S-2100+ / HT6000+, it must be used on a roof to support the chimney. 2. It may be used on a floor, ceiling or roof above an offset to support the chimney above the offset. 3. It may be used on a floor, ceiling or roof as a supplementary support. 16” (410 mm) 18” (460 mm) 16” (410 mm) 18” (460 mm) Table 6 gives maximum height of supported chimney.
INSTALLATION INSTRUCTIONS FOR MASONRY APPLICATION Follow these steps: WARNING: Before starting the installation, the masonry chimney must be inspected by a qualified chimney sweep. 1. Position the fireplace in its location. Temporarily install the ASHT+ elbow on the top of the fireplace and, using a level, mark with an oval the location where the flue liner will enter the masonry chimney. 2. In the middle of the oval, drill a hole in the masonry chimney at 30º. 3.
