Lennox Hearth 1000

9.0 SITE REQUIREMENTS

This appliance is designed to be wall-hung. Do not recess any part of

the appliance into the wall.

This appliance may be installed in any room in a home except bathrooms

- or areas where large amounts of steam are likely to be generated. This

appliance is approved for installation into a bedroom .

It should be noted that heaters create warm air currents. These currents

move heat to wall surfaces next to the heater. Installing the heater next

to vinyl or cloth wall coverings or operating the heater where impuri-

ties in the air (such as tobacco smoke or candle smoke) exist, may

discolor walls.

Installation in living rooms is common, however other rooms such as

kitchens, dining rooms and hallways are permitted, providing a suitable

gas supply is available, and rooms sizing and ventilation requirements

are strictly adhered to (see Section 8.0).

The appliance is designed to be versatile, and as such will operate correctly

when exposed to normal gentle drafts experienced within the home. It is

not recommended, however that the appliance be installed in areas where

it is likely to be exposed to persistent strong drafts, that may be generated

by outside doors or windows, air vents etc. It is recommended that the

appliance should not be installed within 20" of any air vent.

10.0 GAS SUPPLY ROUTES

Gas connection: The heater gas inlet connection is 3/8” NPT at the

regulator, located below the burner, in the right hand side of the heater.

There are four possible entry points for the gas supply pipe-work to

enter the appliance ﬁrebox. These entry points are ‘knock out’ type holes

(shown in Figure 1).

Clearance to the sides of the appliance are 4” but curtains, drapes and

other fabrics are not permitted within a distance of 20” of the appliance

sides. No such materials are permitted directly above the appliance

regardless of distance.

The minimum clearance to the ceiling above the appliance is 32” mea-

sured from the top of the appliance glass panel.

Combustible materials should not be positioned directly in front of the

appliance within a distance of 40”.

Under no circumstances should any electrical equipment e.g. plasma

screen TV sets etc. be positioned on the wall above the appliance. The

appliance is designed to be wall mounted alone and not in conjunction

with any type of combustible ﬁre surround.

No combustible shelves should be positioned on the wall above the

appliance.

It should be established that any mirrors or picture frames etc. to

be positioned on the wall above the appliance are able to withstand

prolonged exposure to moderate heat and moisture before proceeding

with their installation.

The wall must be structurally sound and constructed from a material

capable of withstanding moderate heat. Finished plaster, conventional

wall paper and dry-lined plasterboard are examples of suitable materi-

als. Materials such as ﬂock, blown vinyl and embossed paper which are

sensitive to even small amounts of heat should be avoided as scorching

and or discoloration may occur over time.

If the appliance is to be mounted on a dry-lined wall or a timber framed

construction wall then the integrity and ability of the wall to carry the

weight of the appliance must be conﬁrmed. It is important in these

circumstances that any vapor control barrier is not damaged, and that

any structural members of the house frame are not damaged.

The appliance may be positioned as close to a solid ﬂoor (i.e. stone,

wooden laminate etc.) as the particular design of ﬁre frame permits,

however it is not permitted to install the appliance within 4” of carpet,

rugs or fabric materials of any kind. This dimension is measured verti-

cally to the bottom of the appliance frame.

CLEARANCES TO NON-COMBUSTIBLES

Non-combustible surfaces are deﬁned as brick, metal, marble, concrete

etc. and also a number of man-made materials impervious to ﬂame. If in

doubt refer to the material manufacturer for further information before

proceeding with installation.

Clearances to the sides of the appliance are 4”. Clearance to the front

of the appliance is 20”.

The appliance may be installed with or without a non-combustible hearth.

If a hearth is ﬁtted, the size and design may be as desired.

A non-combustible shelf of any depth may be positioned above the appli-

ance provided it is no closer than 16” from the top of the appliance glass

panel and the wall above the appliance is non-combustible.

CLEARANCES TO COMBUSTIBLE MATERIALS

Combustible materials are deﬁned as wood, fabrics, or other materials

likely to combust if exposed to ﬂame. Generally, any material, which is

likely to discolor, melt or misshape when exposed to moderate heat,

should be considered as a combustible material or surface.

CAUTION

The back of the appliance may be installed directly

onto a combustible wall or non-combustible wall,

providing the area behind the appliance is ﬂat and

does not interfere with the various vent holes in the

back panel of the appliance.
