FIREPLACE MAINTENANCE

CREOSOTE

Formation and Need for Removal

When wood is burned slowly, it produces tar
and other organic vapors, which combine
with expelled moisture to form 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
and extremely hot fire.

The chimney shall be inspected at least twice
a year during the heating season to determine
when a creosote buildup has occurred.

When creosote has accumulated it shall be
removed to reduce the risk of a chimney fire.

When 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 sure there is always
visible flame burning, avoid smouldering fires
and by proper refuelling techniques.

CHIMNEY MAINTENANCE

Fastening

Screws

Interior Frame

Frame
Screws

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.

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.

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.

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 CARE

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
ME43 fireplace. Replacement glass should be
purchased from your local LHP dealer.

NOT OPERATE THE UNIT WITH CRACKED OR
BROKEN GLASS.

unscrew the frame screws, remove the interior
frame and the glass panel.

To remove the glass panel,

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.

pads, steel wool or oven cleaner as they will
scratch the glass.

DO NOT USE CHEMICAL GLASS CLEANERS
ON PAINTED SURFACES AS IT MAY CAUSE
THE PAINT TO PEEL.

CAUTION : DO NOT ALLOW WINDOW CLEANER
TO GET IN CONTACT WITH DOOR GASKET OR
PAINT ON FACADE OR DOOR. ONCE CLOSED,
CONTACT OF GLASS CLEANER WITH THE
FIREPLACE FACADE CAN PROVOKE PAINT
PEELING OFF.

Do not use abrasives such as steel

Disposing Of Ashes

Remove ashes only when the fire is out and
the ashes are cold (24 to 48 hours after the
fire is out).

Do not leave the ashes in the house as they give
off carbon monoxide and other toxic gases.

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. 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.

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.

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’’).

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 Figures 7A and 7B)
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. The sup­plied safety metal strip must be positioned
as follows: One half under the front of the
fireplace and the other half must extend on
the floor over which the hearth extension will
be built (see Figure 7A).

* The safety metal strip must cover the entire

width of the fireplace.

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.

Fireplace

The crack between the fireplace
and the hearth extension must be
sealed with a non-combustible
material such as sand-cement
grout.

Elevated Fireplaces

u Elevated fireplace installations

require a special “Z” Metal
Safety Strips (field provided),
in place of the safety metal strip
shown above. The safety strip
should extend the full width of
the fireplace. When more than

Cold Climate Installations

Climates where temperatures will fall below
32° F (0° C).

The heating performance of the appliance will
vary depending upon the level of insulation,
house design, how the appliance is operated,
etc.

If this fireplace is being installed in a cold
climate, it is especially important to seal all
cracks around the fireplace and wherever cold
air could enter the room with noncombustible
material. Also, the outside air inlet duct should
be wrapped with noncombustible insulation to
minimize the formation of condensation. Do
not place insulation materials directly against
the chimney sections. We recommend that you
use the insulated wall radiation shield since it
will maintain the home’s thermal barrier. AC
chimney is NOT recommended in very cold
climates (in areas with temperatures below
0° F (-18° C).
