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%. 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.

This appliance is factory set for operation on the gas type, and at the
pressure stated on the appliance rating plate.

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
combustion and draws combustion air from the outdoors.

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,
Section 5.3.

b.

Vent room directly to the outdoors. Refer to National Fuel Gas Code,

ANSI Z223.1, Section 5.3.
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.

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 impurities in the air (such as tobacco smoke or
candle smoke) exist, may discolour walls.

Installation in living rooms is common, however other rooms such as
kitchens, dining rooms and hallways are permitted, providing a suitable
natural gas supply is available, and rooms sizing and ventilation
requirements are strictly adhered to (see section 4).

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.

National Fuel Gas Code ANSI Z223.1 or NFPA54 which can be obtained
from The American National Standards Institute, Inc. (1430 Broadway, New
York, NY, 10018) or National Fire Protection Association, Inc. (Batterymarch
Park, Quincy, MA, 02269).

Seller of unvented natural gas fired supplemental room heaters in the
commonwealth of Massachusettes shall provide to each purchaser a copy
of 527 CMR 30 upon sale of the unit. Please refer to section 4.0 on page 2
of this manual.

This Lennox Hearth Products unvented gas room heater is certified by
OMNI-Test Laboratories, Inc to ANSI Z21.11.2-2007 standard.

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 National Fuel Gas Code, ANSI Z223.1/NFPA 54 defines a confined
space as a space whose volume is less than 50 ft 3per 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 ft 3per 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 continuous
water vapor retarder with a rating of one perm or less with openings
gasketed or sealed, and

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 wallceiling 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.

Determine the volume of space — ft 3.

WARNING

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 back of the appliance may be installed directly onto a 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.

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 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 discolour, 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 prolonged
exposure to moderate heat and moisture before proceeding with their
installation.

The back of the appliance may be installed directly onto a combustible wall,
providing it is flat and does not interfere with the various vent holes in the
back panel of the appliance. 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 materials. 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 vertically to the
bottom of the appliance frame

.

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 pipework to enter
the appliance firebox.
These entry points are
‘knock out’ type holes
(shown in figure 1).
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 knock
out hole in the centre
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 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 pipework and fittings should be used.
Joints should be kept to a minimum and compression fittings must not be
used. The pipework installation must be tested for soundness before any
protection is applied and/or the pipework and fittings are buried.

After having selected the final mounting position of the appliance, taking
into account the site requirements as specified in section 7 of these
instructions, the integrity of the wall, and the feasibility of the proposed
supply pipe routing, the firebox of appliance may be secured to the wall.

Figure 1

DO NOT USE A BLOWER INSERT, HEAT EXCHANGER
INSERT OR OTHER ACCESSORY NOT APPROVED FOR
USE WITH THIS HEATER.

WARNING

DO NOT ALLOW ANY FANS TO BLOW DIRECTLY INTO
THE FIREPLACE. AVOID ANY DRAFTS THAT ALTER
BURNER FLAME PATTERNS.

WARNING

There are no imitation fuel bed components 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.

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 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.

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 absolutely 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.

A full size fitting template is supplied to assist with wall mounting.

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 1/4” masonry bit. 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.

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
spirit 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.

IMPORTANT

The pressure test
points are located as
shown in figure 7. An
alternative burner
(mainfold 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 the
Appliance Data sec­tion on page 2,
replace the regulator
with P/N H6063.
Replace the test
point screws after
pressure
measurement
ensuring no gas
leaks. All instructions
must be handed to
the user for
safekeeping.

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. If
under any circumstances
the piezo electric spark
fails, the pilot cannot be lit
manually.

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.

7

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 11).

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.

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

2. Slide on the side pieces ensuring that the grille fixing holes (shown)
are aligned towards the top of the glass facia (as shown in figure 11).

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.

4. Position the grille within the two side pieces ensuring a neat fit.

5. Secure the grille in position using two M6 screws and two no. 8 self
tapping screws as shown in figure 14.

The glass facia panel is supported by four M6 screws which protrude
from the front of the outer casing. Insert the M6 retaining screws and
ensure they are unscrewed approximately 1/8” so the keyhole shaped
holes may engage, and the facia can be hooked on. Ensuring that the
corresponding keyhole shaped holes engage the screwheads fully.
Refer to figure 15.

Remove the two side panel

assemblies from the protective

packaging and fit onto the sides of the

firebox as shown. Insert the M6

retaining screws in the sides of the

firebox and ensure they are

unscrewed approximately 1/8” so the

keyhole shaped holes may engage,

and the sides can be hooked on.

M6 ‘a’ screws only.

The right-hand side panel
has a hinged flap to allow
access to the control knob.

After commissioning the appliance, the customer should be instructed
on the safe use of the appliance and the need for regular servicing.
Frequency of service depends on usage, but MUST be carried out at
least once annually.

Advise that cleaning of the fireplace may be achieved when the
fireplace is cold using a damp cloth and mild detergent on most
surfaces.

Advise that the fireplace will emit an odor for a time after initial
commissioning and that extra ventilation may be needed during this
time. A periodic visual check of the pilot flame and the burner flame
should be carried out. (Refer to figure 22).

A suggested procedure for servicing is detailed as follows;

Turn off the fireplace at the the gas supply. Ensure that the fireplace is
fully cold before attempting service.

1. Lay out the dustsheet and tools.

2. Remove the front glass facia as described in section 16.0,
only in reverse.

3. Remove the glass door assembly (5 screws) and clean
carefully. Remove the valve cover plate (4 screws).

4. Inspect the burner and the catalysts and clean if necessary
with a soft brush.

5. Disconnect the gas supply.

6. Undo the four screws retaining the burner support brackets to
the base and rear of the firebox.

7. Remove the burner unit, strip off the burner pipes and clean
thoroughly.

8. Clean the in-line restrictor, pilot assembly and the burner
tube. Do not attempt to remove the pilot injector as this can
cause damage.

9. Re-assemble components.

10. Turn on the gas supply and leak test. Check pilot and
burner for good ignition.

11. Refit the valve cover and retaining screws.

12. Refit the glass door assembly.

13. Refit the facia Refitting as described in section 15.0.

14. Check the purpose provided ventilation is unobstructed.

15. Light the fire and test setting pressures.

16. Check safe operation of the appliance.

For specific servicing instructions, see relevant sections.

First, remove the front Glass facia as described in Section 16.0 only in
reverse, remove the valve cover (4 screws) and disconnect the gas
connection inside appliance. The gas connections to the gas valve can
now be released. Undo the four screws retaining the burner brackets to
the base and rear of the firebox. The burner may now be removed.

Remove the pilot and main burner pipes and blow through to dislodge
any debris. Now remove the in line restrictor and blow through to make
sure it is entirely clear.

Unclip the pilot lint gauze and clean with a soft brush. 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. The
pilot assembly can be removed if required by disconnecting the
electrode HT lead, gas pipe, thermocouple lead and unscrewing the
mounting screws and lifting away. The pilot assembly is a non­serviceable item and should not be taken apart. Aeration holes must be
absolutely clear internally for proper operation. NEVER MODIFY OR
BEND THE THERMOCOUPLE TO MAKE THE PILOT STAY ALIGHT.
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.
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.
Re-assemble in the reverse of removal. Ensure setting pressures are
as stated in Section 3; Appliance Data.
