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. If the creosote accumulation is large, a creosote fire in the chimney can damage the chimney and over­heat the surrounding wood framing. Creosote formation in a chimney can be minimized by making small hot fires rather than slow burning, smouldering fires.
CHIMNEY MAINTENANCE
Regular chimney inspection and maintenance combined with proper operation will help pre­vent chimney fires. Keep your chimney clean. Do not allow more than a 1/16" (1.6mm) build-up of creosote in your chimney. The amount of creosote will depend on variables such as fre­quency of use and type of fire. We recommend that you follow the instructions below:
1. Initially, inspect the chimney system weekly. By doing this, you will learn how often it will be necessary to clean your chimney.
2. Have your chimney cleaned by a qualified chimney sweep. Chimney maintenance should only be conducted by a qualified technical or chimney sweep company.
3. Do not expect chemical cleaners to keep your chimney clean.
The raincap can be removed for inspection and/or cleaning of the chimney. Unscrew the braces which attach the raincap to the chimney. Using gloves, firmly grip the upper portion of the rain cap. Turn the cap and lift it off the chimney.
6. Watch for smouldering or fire on combustibles next to the fireplace and chimney. Check outside to ensure that sparks and hot embers coming out of the chimney are not igniting the roof.
7. Do not use the fireplace again until your chimney and fireplace have been inspected by a qualified chimney sweep or a fire department inspector.
Door Frame Care
Use a glass cleaner and a soft cloth to polish the frame. Do not use abrasives such as steel wool or steel pads for they may scratch the door frame finish.
Glass Cleaning
The ME43 fireplace is designed to keep the glass clean under normal operating condi­tions. To clean the glass there are a number of specially designed cleaners. Your authorized LHP Dealer can recommend a suitable cleaner. Regular household glass cleaners will not clean creosote. Do not use abrasives such as steel pads, steel wool or oven cleaner as they will scratch the glass.
Doors Adjustment
Glass doors may lose their adjustment during transportation or installation of the fireplace. A wrong adjustment may cause a loss in combustion’s efficiency and control. The glass doors must be parallel, at the same height and must almost touch each other when closed. Maximum spacing between the doors is one sixteenth of an inch (1/16’’).
The glass doors can be adjusted by loosening the three (3) screws of the hinges’ supports (see fastening screws in Figure 1). If a minor angular adjustment is needed, you may loosen only two (2) of the three (3) screws using the other as a pivot point.
Glass Replacement
The glass used for the ME43 fireplace doors is a high temperature ceramic glass. If the glass breaks, it must be replaced with a ceramic glass such as Neoceram. Tempered or ordinary glass will not withstand the high temperatures of the ELITE ME43 fireplace. Replacement glass should be purchased from your local LHP dealer. Do not operate the unit with cracked or broken glass. To remove the glass panel, unscrew the frame screws, remove the interior frame and the glass panel.
Removal Of Ashes
Remove ashes only when the fire is out and the ashes are cold. Lift the front of the log grate until it rests against the rear refractory; then remove the 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. If the ashes are disposed of by burial in soil or otherwise locally dispersed, they should be retained in the closed container until all cinders have thoroughly cooled. Do not leave the ashes in the house as they give off carbon monoxide and other toxic gases.

CHIMNEY FIRES
If you are having a chimney fire, follow these steps:
1. Close the glass doors and the air inlet.
2. Close the chimney outside air register.
3. Alert your family of the possible danger.
4. If you require assistance, alert your fire department.
5. If possible, use a dry chemical fire extin­guisher, baking soda or sand to control the fire. Do not use water as it may cause dangerous steam explosions.

PUSH TO OPEN
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.
Do not burn scrap or garbage, treated wood or wood such as driftwood from the ocean which has been exposed to salt or other chemicals. Salt or chemicals can corrode the firebox and chimney. Do not abuse the unit by burning large amounts of paper, cardboard, Christmas tree branches or building construction materi­als such as pressed wood, plywood or lumber. Intense firing with these may overheat the fireplace, causing damage to the unit, a fire, or even possibly igniting a chimney fire, if the chimney is creosoted.
First Fires
The first 5 or 6 fires should be small fires of short duration (about 30-60 minutes). The first fire should be especially short. This will help cure the refractory bricks. The first fires may produce slight smoking and some odor due to drying of the paint and steel and any dust accumulated on the fireplace will be burn off at this time. For this reason the room should be well ventilated during the first few fires.
HOW TO USE THE RETRACTABLE DOORS AND FIRESCREENS
The Lennox ME43 fireplace features retractable doors and firescreens in order to allow a wider view of the fire and save space when the doors are opened. To retract the doors, simply open them at 90° and push them into the opening on the side of the firebox. The same procedure applies for the retractable firescreens. (see
Figure 2
Note : Do not operate the fireplace with both fire­screen and doors closed at the same time.
).
Figure 2
HOW TO USE THE OUTSIDE AIR REGISTER (FIREPLACE)
The outside air register is located on the upper part of the top louver. The outside air register supplies oxygen to the fire and allows control of the fire when the doors are closed. The fresh air must come from outside the house (the air intake must not draw air from inside the house). This will minimize negative pressure in the house. The more you slide the register to the left, the more fresh air into the firebox and the more accelerated combustion you will get (see Figure 3). When starting a fire, the register should always be fully opened.
FIREPLACE INSTALLATION
Preinstallation
Please Read Before Installing:
1. Before beginning the installation of your fireplace, read these safety tips and instal­lation instructions carefully to be sure you understand them completely. Failure to follow them could cause a fireplace malfunc­tion resulting in serious bodily injury and/or property damage.
2. The ME43 fireplace has been tested and listed to UL and ULC standards by Warnock Hersey International Inc. These instructions were written to give you an outline for a fast and safe installation and trouble-free operation.
Building A Fire
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, crisscrossing the kindling so that there is airspaces in between. Place the larger pieces of kindling on top of the pile. Keep the fuel far back enough so that air can get underneath. Open the air control fully and light the newspaper. Once the kindling fire is well established, cordwood can be added.
The unit will burn best with a minimum of two pieces of cordwood spaced 1" to 2" apart and al­lowing air to get under the fuel. Crisscrossing or arranging the fuel so that air can get underneath, will help the fire to get started easily.

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. Check with the local building authorities before installing to determine what other materials are acceptable in your area.
2. The hearth extension should be secured to the floor. The gap between the fireplace and the hearth extension must be sealed with non-combustible caulking or cement.
3. On a raised base or raised hearth, a “Z” shape piece of metal must be fabricated to join the bottom of the fireplace to the floor.
Outside Air Assembly
The outside air assembly is mandatory for the fireplace.
During operation, the fireplace requires air for combustion and draws air out of the house. It may starve other fuel burning appliances such as gas or oil furnaces. As well, exhaust fans and fan driven appliances may compete for air, causing a negative pressure in the home, resulting in smoke entering the home from the fireplace. This situation is aggravated in modern airtight houses.
To overcome this potential problem, the
installation of an outside air assembly is required to provide outside combustion air to
the fireplace.
Outside Air Installation
The outside air assembly must be installed according to the following guidelines:
1. The maximum length of 4" I.D. (100 mm)
insulated flexible duct is 20 feet (6.1 m). If a longer duct is required, use a 6" I.D. (150mm) insulated flexible duct. The maximum length is 40 feet (12 m). Refer to Figures 8B and
for connections.
8C
2. The duct and register may be installed above
or below floor level.
3. The outside air register must not be installed
more than 7 feet (2.1 m) above the base of the fireplace.
(Detail A)
4. The outside air assembly must draw air from
outside the house. It must not draw air from the attic, the basement or a garage.
5. Locate the outside register where it will be
well away from automobile exhaust fumes or other vents.
6. The outside air register should be installed
where it is not likely to be blocked by snow or exposed to extreme wind.
7. It is recommended to install the outside air
register at floor level. However, if you must raise the air register above the fireplace level, you will have to make a loop to the floor with the flexible pipe to prevent from causing a draft in the outside air register (see Figure 8 Detail A).
