This appliance is a high efficiency, unvented, flame effect gas
heater. It provides radiant and convected warmth both efficiently
and safely utilizing the latest type catalytic convertor burner
technology. The appliance does not require a flue system of any
type as the catalytic converter cleans the flue products to provide
a complete combustion system, which is intrinsically safe.
These heaters are fitted with a specially designed pilot utilizing an
oxygen depletion sensor (ODS) which responds to the amount
of oxygen available in the room and shuts the heater off before
the oxygen level drops below 18%. It must not be adjusted or
put out of operation. If replaced then manufacturers original
parts must be used. The pilot can be relit only when fresh air is
available. Refer to the Combustion and Ventilation Air section.
The appliance is designed to fit various types of situations as
listed in the installation requirements.

COMBUSTION AND VENTILATION AIR
This heater shall not be installed in a confined space or unusually tight
construction unless provisions are provided for adequate combustion and
ventilation air. The heater may be located in unusually tight construction
provided the space is unconfined, or if confined, is provided with two
permanent openings communicating directly with an additional room(s)
of sufficient volume so that the combined volume of all connected spaces
meets the criteria for an unconfined space, (National Fuel Gas Code
NFPA 54 / ANSI Z223.1 - latest edition, section on Air for Combustion
and Ventilation. Generally 50 ft3 per 1,000 BTU input of all operating
appliances in the space.
The National Fuel Gas Code, ANSI Z223.1/NFPA 54, defines a confined
space as a space whose volume is less than 50 ft3 per 1,000 BTU/Hr
(4.8 m3 per kW) of the aggregate input rating of all appliances installed
in that space and an unconfined space as a space whose volume is not
less than 50 ft3 per 1,000 BTU/Hr (4.8 m3 per kW) of the aggregate input
rating of all appliances installed in that space.
Rooms communicating directly with the space in which the appliances
are installed, through openings not furnished with doors, are considered
a part of the unconfined space.
Unusually tight construction is defined as construction where:
a. Wall and ceilings exposed to the outside atmosphere have a continu-
ous water vapor retarder with a rating of one perm (6 X 10-11 kg per
pa-sec-m2) or less with openings gasketed or sealed;
b. Weather stripping has been added on operable windows and doors;
and
c. Caulking or sealants are applied to areas such as joints around window
and door frames, between sole plates and floors, between wall ceiling
joints, between wall panels, at penetrations for plumbing, electrical,
and gas lines, and at other openings.
Use the following equations to determine if you have a confined or
unconfined space.
1. Determine the volume of space — ft3.
Length x Width x Height = _____ ft3
(Include adjoining rooms with doorless passageways or ventilation
grills between rooms).
Example: 24' (L) x 16' (W) x 8' (H) = 3072 ft3
2. Divide the volume of space by 50 ft3 to determine the maximum BTU/Hr
the space can support.
______ (volume of space – ft3)/ 50 ft3 =
(Maximum BTU/Hr the space can support)
Example: 3072 ft3 / 50 ft3 = 61.44
or 61,440 BTU/Hr the space can support.
3. Add the BTU/Hr of all the fuel burning appliances in the space.
Vent-Free heater _______ BTU/Hr
Gas appliance #1* _______ BTU/Hr
Gas appliance #2 + _______ BTU/Hr
Gas appliance #3 + _______ BTU/Hr
Total = _______ BTU/Hr
Example:
Vent-free heater #1 9,000 BTU/Hr
Vent-free heater #2 23,000 BTU/Hr
Gas appliance #1 35,000 BTU/Hr
(water heater)
Total = 67,000 BTU/Hr
* Do not include direct-vent gas appliances. Direct-vent is sealed com-
bustion and draws combustion air from the outdoors.
4. Compare the maximum BTU/Hr the space can support with the actual
amount of BTU/Hr used.
_______ BTU/Hr (max. the space can support)
_______ BTU/Hr (actual amount of BTU/Hr used)
Example:
61,440 BTU/Hr (max. the space can support)
67,000 BTU/Hr (actual amount of BTU/Hr used)
The space in the previous example is a confined space because the actual
BTU/Hr used is more than the maximum BTU/Hr the space can support.
You must provide additional fresh air.
Your options are:
a. Rework equations adding the space of adjoining room(s). If the extra
volume provides an unconfined space, then remove door or add
ventilation grills between rooms. Refer to National Fuel Gas Code,
ANSI Z223.1/NFPA 54-latest edition, section "Air for Combustion and
Ventilation".
b. Vent room directly to the outdoors. Refer to National Fuel Gas Code,
ANSI Z223.1/NFPA 54-latest edition, section "Air for Combustion and
Ventilation".
c. Install a lower BTU/Hr heater to make the area an unconfined space.
If the actual BTU/Hr used is less than the maximum BTU/Hr the space
can support, then the space is an unconfined space. You will need no
additional fresh air ventilation for an unconfined space.
WARNING
If the area in which the heater may be operated is
smaller than that defined as an unconfined space
or if the building is of unusually tight construction,
provide adequate combustion and ventilation air by
one of the methods described in the national fuel
gas code, ANSI Z223.1/NFPA 54, Air for Combustion
and Ventilation Or applicable local codes.
WARNING
If the area in which the heater may be operated does
not meet the required volume for indoor combustion
air, combustion and ventilation air shall be provided
by one of the methods described in the National Fuel
Gas Code, ANSI Z223.1/NFPA 54, the International
Fuel Gas Code or local applicable codes.

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 bedrooms
or bathrooms - or areas where large amounts of steam are likely to be
generated.
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 Page 8).
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.
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.
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” measured
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 pro-
longed 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.
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.

10 NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE
Non-concealed gas connections may be made
using the entry points on the base of the firebox.
A concealed gas connection may be made using
the knockout hole in the center back of the firebox.
Select the most appropriate entry point and knock
out the relevant hole.
No more than 59" of 1/4" diameter pipe must be used
to avoid unnecessary pressure drops.
If a concealed gas con nection is to be made, the
supply pipe should always be sleeved through walls
and floors using the shortest possi ble route.
For concealed supply pipe routing, pipes must
(where possible) be ver tical and providing there is
sufficient wall thick ness available, they should be
placed in pipe chases. Horizontal pipe runs should
be avoided where possible. Prior to chasing a
solid wall, an inspection should be made to note
the proximity of any cables/sockets outlets which
may already be buried. Pipes must be secured using
suitable clips and protected against corrosion.
Ideally factory finished protected pipe-work and
fittings should be used. Joints should be kept to
a minimum and compression fittings must not be
used. The pipe-work installation must be tested for
soundness before any protection is applied and/or
the pipe-work and fittings are buried.
Remove the wall mounting plate from the back of the appliance firebox by removing the two
retaining wing nuts (indicated by arrows in Figure 2) from the retaining studs that protrude
into the lower part of the main firebox.

GAS SUPPLY ROUTES
IMPORTANT NOTE: All gas piping must be done by
a licensed plumber or gas fitter and must conform
to the requirements of the National Fuel Gas Code
NFPA 54 / ANSI Z223.1 - latest edition.
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).
