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

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 for Combustion
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 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.
Figure 1 - Gas Supply Entry Points
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.
NOTE: See Page 19 for gas
line entry point dimensions.

7
Non-concealed gas connections may be made using the
entry points at either end of the firebox or the one in
the bottom of the firebox. A concealed gas connection
may be made using the knock out hole in the center
back of the firebox. Select the most appropriate entry
point and knock out the relevant hole in both the firebox
and the outer casing.
No more than 59" of 1/4" diameter pipe must be used
to avoid unnecessary pressure drops.
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 vertical 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
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.

the integrity of the wall, and the feasibility of the proposed supply pipe
routing, the firebox of appliance may be secured to the wall.
12.0 MOUNTING THE APPLIANCE
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.
A full size fitting template is supplied to assist with wall mounting. (see
Figure 3).
If the heater is to be installed on a studded wall with conventional 16”
stud spacing then a wall mounting plate is supplied to enable this. NOTE:
THIS APPLIANCE MUST BE SECURED DIRECTLY TO THE STUDS AT THE
FIXING POINTS THAT ARE 16" DISTANCE (see template below). First
locate the studs and using suitable fixings, screw the mounting plate to
the wall via the four mounting holes. The heater may then be hung onto
the mounting plate. The bottom of the heater may be secured onto the
lower mounting studs using the wing-nuts or the hex nuts provided.
Mark the positions shown as “Fixing Points” on the wall. If the appliance
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 fiber 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.
Figure 3 - Wall Fixing Template
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.
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.

It is recommended that the burner height, where possible, should
be approximately 4 ft. from the floor. This will give the best viewing
position. When selecting the height, ensure that the clearance to the
ceiling is 32" minimum, as specified on Page 6.
After selecting the final mounting position of the appliance, taking into
account the site requirements as specified in Section 9.0 of these
instructions, the integrity of the wall, and the feasibility of the proposed
supply pipe routing, the firebox of the appliance may be secured to the
wall.
Due to the weight of the front surround assembly, it is possible to fasten
the outer casing to the wall in up to nine positions, depending on the
strength/condition of the wall. If in doubt always use extra fixings!
Use a bubble level to ensure that the outer casing is level at all times
during installation.
Insert the screws into two of the upper holes, leaving 3/16" protruding
from the wall. Temporarily hang the outer casing on the wall, and mark
any additional fixing points as required. If the appliance is to be fitted
to a lightly colored wall, it is advantageous to paint this wall area with
black or dark paint in the vicinity of the lower rectangular slots on the
outer casing. This will mask the wall when viewed from the front of the
appliance. Ensure paint is fully dry before mounting the appliance. Use
the outer casing as a template to mark this area on the wall. Remove
the outer casing from the wall and drill holes for the additional fixing
points as required. Insert either wall plugs or cavity screw fixings as
required. Re-position the outer casing on the wall and using a bubble
level to check the casing is square and level, tighten all of the fixing
screws fully.
Now, with the outer casing fixed to the wall, the main firebox can be
secured in position. The firebox is held on the outer casing using four
studs and two normal nuts (upper fixings) and two wing nuts (lower
fixings). Make sure that the upper nuts are unscrewed approximately
one turn from the fully tightened position in order to create a 1/16" gap
as shown in Figure 4. The firebox may now be hung onto the top studs,
and then pushed onto the lower studs so that the lower studs protrude
through the lower fixing holes in the back panel of the firebox.
Next, re-fit the grill, the indicator bracket and the control knob and
spindle, and secure in position using the correct fixing screws (re-fitting
is the opposite of removal as detailed in these instructions).
Figure 4
1/16"
13.0 FITTING THE SURROUND ASSEMBLY
Due to the weight of the frame assembly, it is recommended to seek
assistance for this operation.
The frame assembly will be supported by keyhole slots by four M6
screws which protrude from the front of the outer casing (see Figure 5)
. Ensure each screw is unscrewed approximately one turn from the fully
screwed in position in order to create a 1/16" gap (shown). Hang the
surround assembly onto the outer casing, starting with the two bottom
fixings, ensuring that the corresponding keyhole shaped holes engage
the screw heads fully.

Heat Shield
IMPORTANT NOTE: Ensure that the
surround is positioned with the
heat shield on top as shown.

10 NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE
14.0 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.
15.0 CONNECTING A GAS LINE
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. A flex gas line kit with shut-off valve is
available (see Page 16 or ordering information).
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).

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
Holdheaterregulatorwithawrenchtopreventmove-
ment when connecting to inlet piping.
16.0 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 control
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.
17.0 GAS PRESSURE CHECK
WARNING
Never use an open flame to check for leaks.
Checking Manifold Pressure at Provided Test Point (see Figure 7a) -
The pressure test point is located on the left hand side of the appliance,
on the main burner pipe, next to the brass restrictor adjacent to the
front left hand side burner bracket. Release the setting pressure test
point screw, and attach a U gauge. Light the fire on the HIGH setting.
Checking Manifold and Inlet Pressure at Valve (see Figure 7b) - The
heater regulator controls the burner pressure which can be checked at
the pressure test points located on the control valve itself for burner
(manifold) and regulator (inlet) setting pressures.
The valve is located on the lower right side of the appliance (see
exploded view drawing on Page 17). Release the test point screws and
ensure operating pressures are as specified in Table 1 on Page 3 of
these instructions. The pressure should be checked with the gas heater
burning and the control set to high flame.
NOTE: See Page 19 for gas line entry point dimensions.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE 11

Pressure Setting
If the pressure is too high, the gas supply meter may be set incorrectly.
This should be checked with the appliance running and if necessary
reset by the gas supplier. If the burner pressure is too low, then check
the inlet pressure with the appliance running. If this is less than the inlet
pressure stated in Table 1,it will need to be reset by the gas supplier.
If the setting pressure is too low, but the meter pressure is acceptable,
then a problem in the supply pipework is to be suspected. This may
be dirt and debris, kinked or inadequate size pipes, restriction in a
fitting, shut off elbow not fully open or solder flashing across a joint.
Identify the cause of the restriction and rectify. Switch the fireplace
off, disconnect the U gauge and refit the test nipple screw. Light the
fireplace and check test nipple for gas tightness. In the event that the
burner pressure is not in accordance with the figures stated in the Table
1of these instructions, the appliance must not be commissioned, and
the dealer should be contacted for guidance.
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.

18.0 SPARK GAP
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.
19.0 BRIEFING THE CUSTOMER
WARNING
Do not add logs or ornaments such as pine cones,
vermiculite or rock wool. Using these added items
can cause sooting.
All instructions must be left in the possession of the user for safekeeping.
Show the customer how to light and control the fire. If at all possible,
show the customer how to remove and replace the surround assembly
and glass door assembly.
After commissioning the appliance, the customer should be instructed
on the safe use of the appliance and the need for regular servicing. Fre-
quency of service depends on usage, but MUST be carried out at least
once annually. Advise that cleaning of the appliance may be achieved
when the appliance is cold using a damp cloth and mild detergent on
most surfaces.
Advise that the fireplace will emit a "newness" smell for a time after
initial commissioning and that extra ventilation may be needed during
this time.
Advise to user to never place any objects on top of the appliance or
obstruction this area in any way.
A periodic visual check of the pilot flame and the burner flame should
be carried out.

WARNING
You must keep control areas, burners and circulat-
ing air passageways of appliance clean. Failure to
keep the primary air opening(s) of the burner clear
may result in sooting and property damage. Inspect
these areas of appliance before each use. Have
appliance inspected yearly by a qualified service
person. Appliance may need more frequent clean-
ing due to excessive lint form carpeting, bedding
material, etc.
7. Remove the burner unit, strip off the burner pipes and clean thor-
oughly.
8. Clean the in-line restrictor, pilot assembly and the burner tube. Clean
the exterior of the pilot assembly with a soft brush and blow through
the flame ports on the pilot head. Check the aeration holes are free
from lint or dirt. Do not attempt to remove the pilot injector as this
can cause damage. The pilot assembly is a non-serviceable item and
should not be taken apart. Aeration holes must be clear internally for
proper operation. NEVER MODIFY OR BEND THE THERMOCOUPLE
TO MAKE THE PILOT STAY LIT. Modifications are dangerous and can
have serious unseen effects on safety. If the pilot will not stay lit there
is a problem with dirt, the gas supply to it, or the thermocouple needs
replacement.
9. Re-assemble components.
10.Re-connect the gas supply. Turn on the gas supply and perform a gas
leak test using gas leak test solution. Check pilot and burner for good
ignition.
11.Refit the valve cover and retaining screws.

13.Refit the surround assembly as described in Section 13.0.
14.Check the purpose provided ventilation is unobstructed.
15.Light the fireplace and test setting pressures.
16.Check safe operation of the appliance.
NOTES:
• The gas valve is a non-serviceable item. If this needs replacement,
remove the cover plate then the securing screw holding the valve
bracket in place, remove all pipe unions, and the complete valve.
Replacement must be original manufacturers parts.
• Ensure setting pressures are as stated in Table 1 on Page 3.
GLASS PANEL -This can be cleaned with a suitable glass cleaner. The
following solutions are approved for use to clean glass.
• Non-ammonia based household cleaner
• 50% -50% mix of white vinegar and water
• Gas fireplace/stove glass cleaner
PAINTED AREAS - These can be cleaned using a dry cloth.
LIMESTONE SURFACES: Remember that limestone is porous and
therefore susceptible to marking in use. The limestone frame may be
cleaned with a small amount of warm soapy water. Any stubborn stains
may be removed with a diluted liquid household bleach and water solu-
tion. Superficial scratches or stubborn surface stains can be smoothed
out using a fine grade wet and dry sandpaper. Joints may be grouted
using a matching tile grout. The limestone frame may be sealed with
an appropriate stone sealer (consult the retailer). This will give some
protection against staining such as red wine, tea or coffee, but may
darken the stone slightly.
GRANITE SURFACES: In everyday use, a soft lint-free duster should be
used to keep the granite clean. Other marks, such as fingerprints may
be removed from the granite frame by using household window-glass
cleaner.
For specific servicing instructions, see relevant sections.
20.0 SERVICING
WARNING
Turn off the appliance and allow to cool before
cleaning. Verify proper operation after servicing.
The appliance should be checked on an annual basis to ensure it is work-
ing safely and that there is no excessive build up of soot. The frequency
of service will depend on usage, but MUST be carried out at least once
annually. Servicing must be carried out by a qualified person, such as
a NFI certified technician.
Turn off the fireplace at the gas supply. Ensure that the fireplace
is fully cold before attempting service. A suggested procedure for
servicing is detailed as follows;
1. Lay out the dustsheet and tools.
2. Remove the granite or limestone surround assembly as described
in Section 13.0, only in reverse.
3. Remove the glass door assembly (4 screws) and clean carefully.
Remove the valve cover plate (4 screws).
4. Inspect the burner and the catalysts (see Section 21.0)and clean if
necessary with a soft brush. Ensure there are no defects or obstruc-
tions that may prevent the satisfactory flow of combustion products
through the catalysts.
5. Disconnect the gas supply. IMPORTANT NOTE: This must be done by
a licensed plumber or gas fitter and must conform to the require-
ments of the National Fuel Gas Code NFPA 54 / ANSI Z223.1 - latest
edition.
6. Undo the four screws retaining the burner support brackets.

21.0 CATALYSTS
WARNING
Donotblockthecatalystsortheapplianceoutletgrill.
Blockage may cause high carbon monoxide levels
and/or breakage of the glass door assembly.
It is recommended that the catalysts are inspected for signs of damage
and dirt during routine servicing procedures. The expected life of the
catalysts is in excess of 11,000 hours (10 years of normal use). After
this time the catalyst should be replaced.
If there are any deposits of dirt or soot on the catalysts they should be
cleaned with a soft brush and a vacuum cleaner. If removed for cleaning
ensure the seals are in good condition before replacing the catalyst. New
seals will usually be required.
The performance of the catalyst may be checked using a combustion
gas analyzer as follows.
IMPORTANT: The temperature of the gases emitted by the catalytic
converters reach very high temperatures (up to 700° F). Measuring
gas of this temperature may damage some types of gas analyzers. If
in doubt consult the equipment manufacturer.
Turn on the fireplace as per the operating instructions, and run at
maximum setting for 15 minutes. Position gas sample probe directly
over a catalyst via the outlet grill, on top of the appliance. Record the
carbon dioxide (CO2) concentration and then the carbon monoxide (CO)
concentration as displayed by the analyzer - also noting the units in
which the values are expressed. Most analyzers display carbon dioxide
(CO2) concentrations in percentage (%) terms and carbon monoxide
concentration in parts per million (ppm) terms.
In order to calculate the combustion ratio for the appliance (CO/CO2)
it is first necessary to express both gas concentrations in terms of per-
centage. To convert from parts per million (ppm) to a percentage (%)
divide the ppm figure by 10,000. Examples : 35ppm = 0.0035%, 15ppm
= 0.0015%, 5ppm = 0.0005%.
Now divide the concentration of carbon monoxide (CO) expressed in
percent by the concentration of carbon dioxide (CO2) to obtain the
appliance combustion ratio.
CO (%)
CO2(%) = ratio
The combustion ratio of the gasses emitted by the catalytic convertor
should not exceed 0.0015.
If replacing, firstly, remove the glass door assembly as described in Sec-
tion 26.0. The catalysts are located on the top of the internal firebox and
can be removed be unscrewing the retaining nuts securing the clamping
plate. Remove the catalysts and seals and discard.
Refit a new catalysts and seals in reverse order, ensure the catalysts
and door have good seals.
22.0 TESTING FOR FIREBOX LEAKAGE
Appliances that are several years old or have been extensively dismantled
should be checked for soundness. It is important that all the products
of combustion pass through the catalytic converters at the top of the
firebox before leaving the appliance.
The firebox is heated by lighting for a few minutes to provide a flow
through the firebox. The burner is then shut off and a smoke pellet or
match introduced at the base of the fire underneath the burner tray. Large
quantities of smoke will emerge from the top of the appliance, but none
should emerge from the joints or gasket faces, especially around the
door. It is important to note that the appliance can never be expected
to be 100% smoke tight and small quantities of smoke may be seen in
corners of joints and gasket faces etc without affecting safety when the
appliance is in operation.
WARNING
Do not operate the appliance with the catalyst units
removed.
