6.0 BURN-IN PERIOD
On initial light up of a new appliance, the ‘newness’ will burn off within
the first few hours of operation. During this period some smoke may be
emitted from outlet grill, this should be no cause for concern. Accord-
ingly, the room should be well ventilated with all windows and doors
open during this period.
Depending on your use, the burn-in period may take a few hours or a few
days. Also if you have a sensitive sense of smell you may notice slight
odors during operating after the burn-in period is over.
KEEP YOUR HOUSE WELL VENTILATED DURING THE BURN-IN PERIOD.
THE ODOR AND HAZE EMITTED DURING THE BURN-IN PERIOD CAN BE
QUITE NOTICEABLE AND MAY SET OFF A SMOKE DETECTOR. MAKE
SURE SMOKE DETECTORS ARE NOT TOO CLOSE TO THE FIREBOX
(CHECK WITH YOUR LOCAL CODE FOR ALLOWABLE DISTANCES).

8.0 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 ft3per 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 ft3per 1,000 BTU/Hr
(4.8 m3per 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 ft3per 1,000 BTU/Hr (4.8 m3per 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 ft3to 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 forCombustion
and Ventilation Or applicable local codes.

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 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 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.
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.
10.0 PREPARING THE APPLIANCE
Follow the steps below:
Gas connection: The heater gas inlet connection is 3/8” NPT at the
regulator, located below the burner, in the center 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).
Figure 1 - Gas Supply Entry Points
NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE
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
appliance provided it is no closer than 16” from the top of the appli-
ance 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.
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.
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.

7
After having selected the final mounting position of the appliance, taking
intoaccountthe siterequirements asspecifiedinSection8oftheseinstruc-
tions, the integrity of the wall, and the feasibility of the proposed supply
pipe routing, the firebox of appliance may be secured to the wall.
To ensure customer safety, be sure to design the installation so that the
strength of both the wall and any wall fixings used are sufficient. Lennox
Hearth Products assumes no responsibility for injuries and damages that
may occur due to improper installation or handling.
The appliance should not be installed until all dry wall sanding and wall
painting has been completed.
11.0 MOUNTING THE APPLIANCE
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.
If a concealed gas connection is to be made, the supply pipe should always
be sleeved through walls and floors using the shortest possible route.
For concealed supply pipe routing, pipes must (where possible) be ver-
tical and providing there is sufficient wall thickness 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
againstcorrosion.Ideally factoryfinished protected pipe-workandfittings
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.
WARNING
The wall where the appliance is to be installed must
be capable of long-term support of the total load of
the appliance. Measures should also be taken to
ensure sufficient strength to withstand the force of
earthquakes, vibration and other external forces.
Incorrect installation can cause the appliance to fall from the wall and
cause injury. Do not block the ventilation holes of the appliance. The
wall onto which the appliance is installed must be flat. Install only on a
vertical surface. Avoid sloped surfaces. Installation onto anything other
than a vertical wall may result in fire, damage or injury.
A full size fitting template is supplied to assist with wall mounting.
Mark the positions shown as “Fixing Points” on the wall. If the appli-
ance is to be mounted on the inner leaf of a conventional cavity wall,
or a solid wall, drill four holes using a 5/16" masonry bit, to a depth of
1-11/16". Insert the wall plugs provided.
If the appliance is to be mounted on a dry lined wall or a timber framed
construction wall then special cavity screw fixings will be required which
are not supplied with this product. These should be constructed from
metal and not plastic.
If a concealed gas connection is to be made ensure the gas supply pipe
is in it’s final position and can enter the appliance in the correct position
when the appliance is hung on the wall.

Insert the wall mounting screws into the top wall plugs, taking
care to leave the screws protruding approximately 3/8” from the
wall. Now hang the appliance onto these screws through the two
keyhole shaped holes in the back panel of the appliance.
Insert the lower mounting screws into the lower wall plugs
through the corresponding depressed holes in the lower part of
the back panel. Do not tighten fully.
Before tightening the wall mounting screws fully, at this stage
it is recommended to check the horizontal alignment of the
appliance with a bubble level, as small adjustments can still be
made if necessary. When this has been checked, tighten all four
fixing screws fully.
To access the upper fixing screws insert a screwdriver through
the holes in the deflector plates above the catalyst as shown in
Figure 3.
12.0 CHECKING THE BURNER
There are no imitation fuel bed components, such as logs or
rocks, to install. The appliance features a ribbon burner which is
designed to produce a continuous band of flame over its length.
The burner should be visually inspected to ensure it is free from
any foreign matter. If it is necessary to clean or dust off the
burner then the glass door should be removed by removal of
the four retaining screws. Re-fit the glass door after cleaning or
inspection, ensuring a good seal.
13.0 CONNECTING A GAS LINE
11.0 MOUNTING THE APPLIANCE - continued
Figure 3
A qualified gas appliance installer must connect the gas room
heater to the gas supply. Consult all local codes.
The installer must provide an ANSI approved manual shut off
valve, flex connector and 3/8" NPT fitting.
Route gas line using techniques and materials prescribed by
local and/or national codes. Only use pipe of 1/2" or greater size
to allow full gas volume to the gas fireplace. Undue pressure
loss will occur if the pipe is too small.
An external regulator must be used on all propane (L.P.G.)
heaters, in addition to the regulator fitted to the heater, to reduce
the supply tank pressure to 13" w.c. (maximum).

Figure 4
An ANSI approved manual shut-off valve and union must be
installed upstream of the heater within the fireplace cavity
when rigid pipe is used. Ensure that a sediment trap is installed
upstream of the heater (Figure 4)within the structure’s piping
system to prevent moisture and contaminants from passing
through the pipe to the heater controls and burner. Failure to do
so could prevent the heater from operating reliably.
The heater gas inlet connection is 3/8” NPT at the regulator,
located below the burner, in the right hand side of the heater.
When tightening up the joint to the regulator hold the regulator
securely with a wrench to prevent the regulator from moving.
IMPORTANT
Hold heater regulator with a wrench to prevent
movement when connecting to inlet piping.
WARNING
Connecting directly to a unregulated propane tank
may cause an explosion.

14.0 CHECKING THE GAS CONNECTIONS
Turn on gas supply and test for gas leaks using a gas leak test solution
(also referred to as bubble leak solution).
NOTE: using a soapy water solution (50% dish soap, 50% water) is
an effective leak test solution, but it is not recommended, because the
soap residue that is left on the pipes/fittings can result in corrosion
over time.
A. Light the appliance (refer to the lighting instructions label in the con-
trol compartment or on Page 14).
B. Brush all joints and connections with the gas leak test solution to
check for leaks. If bubbles are formed, or gas odor is detected, turn
the gas control knob (off/pilot/on) to the “OFF” position. Either tighten
or refasten the leaking connection, then retest as described above.
C. When the gas lines are tested and leak free, be sure to rinse off the
leak testing solution.
D. Observe the individual tongues of flame on the burner. Make sure all
ports are open and producing flame evenly across the burner. If any
ports are blocked, or partially blocked, clean out the ports.
15.0 GAS PRESSURE CHECK
The heater regulator controls the burner pressure which should
be checked at the pressure test points located on the control
valve itself (shown in Figure 7)for burner (manifold) and
regulator (inlet) setting pressures.
The pressure should be checked with the gas heater burning and the
control set to high flame.
The pressure test points are located on the gas valve. To access the
valve and the test points, firstly remove the control knob spindle from
the valve spindle by removing the retaining clip shown in Figure 5.
Burner (Manifold) Pressure
WARNING
Never use an open flame to check for leaks.
Withdraw the control knob and spindle from the heater, remove the
gas valve cover plate by removing the four retaining screws indicated
in Figure 6.
The pressure test points are located as shown in Figure 7. An alternative
burner (manifold test point is located below the left hand side of the
burner as shown in Figure 8).
The pressure regulator on manual models is preset and locked to avoid
tampering. If the pressure is not as specified in Table 1 on Page 3,
replace the burner assembly (see Page 16 for ordering information).
Replace the test point screws after pressure measurement ensuring no
gas leaks. All instructions must be left in the possession of the user for
safekeeping.

16.0 SPARK GAP
17.0 ASSEMBLY OF THE GLASS FACIA
Figure 9 - Proper Spark Gap
1/8" to 3/16" Spark Gap
Figure 10 - Key Hole Slots on Glass Facia
1. Remove the glass panel from all packaging and lay face down on a soft
surface. Identify the top and bottom of the glass facia by observing
the orientation of the keyhole shaped slots in the facia fixing brackets
as shown in Figure 10.
2. Slide on the side pieces ensuring that the grill fixing holes (shown) are
aligned towards the top of the glass facia (as shown in Figure 11).

Figure 11 - Slide on Side Pieces
3. Ensure the sides are neatly aligned with the glass and secure the sides
using two M6 screws for each side as shown in Figure 12. Do not
overtighten the screws.
IMPORTANT NOTES:
• The screws that are used to attach the brackets to the facia as seen
in Figures 12 and 14 below MUST NOT be over-tightened. Over-
tightening of the mounting screws may cause the glass facia to
slip from its brackets. The screws should be finger-tightened until
all side and top frame pieces are assembled and aligned. At that
point, tighten the screws in 1/4 turn increments until frame pieces
are firmly positioned and do not move.
• If you find that your glass facia is experiencing slippage because of
this over-tightening of the screws, you can use normal RTV sealant
to secure the glass facia to its bracket. Remove the facia from the
fireplace, apply the sealant to the area where the slippage is oc-
curring, and allow the facia to dry face down until the sealant has
dried according to the directions on the sealant packaging.
4. Position the grill within the two side pieces ensuring a proper fit.

The gap between the spark electrode and the pilot should be 1/8” to
3/16” to produce a good spark. There should be no need to adjust this
(DO NOT ATTEMPT TO ADJUST THE GAP). If under any circumstances
the piezo electric spark fails, the pilot cannot be lit manually.
Adjustment to the
pilot is Not allowed
Finger-tighten all screws until side
and top frame pieces are in place
and aligned. At that point, tighten in
1/4 turn increments until frame
pieces are secure. DO NOT
OVER-TIGHTEN.
