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).
