c) Chimney requirement:
DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING
ANOTHER APPLIANCE!
Filiofocus requirement: the floor to top of chimney length must be 17 feet
minimum (20 feet for an installation less than 3 miles from the ocean or if a
30° elbow is necessary). Elbows should not be more inclined than 30° (USA)
or 45° (Canada) from vertical and with maximum number of 2. Maximum
inside + outside height (without use of a fan) : 30 feet.
Windowed filiofocus can be connected to a chimney complying with the
requirements for Type HT chimneys in the standard for Chimneys, Factory-
built, Residential Type and Building Heating Appliance, UL 103/ULC S629.
For example, a class A insulated stainless steel flue chimney system with an
8-inch minimum inside diameter.
CAUTION: THE SUPPORT OF THE ANCHOR PLATE (ROOF
STRUCTURE, SLAB, ETC…) MUST BE SIZED IN CONGRUENCE WITH
THE FIREPLACE STATIC AND DYNAMIC CHARGES. THE SIZE
CALCULATION FOR THE SUPPORT IS NOT THE RESPONSIBILITY OF
FOCUS OR ITS AFFILIATES. IT IS YOUR RESPONSIBILITY TO CONSULT
WITH AN ENGINEER OR ARCHITECT FOR YOUR PROJECT.
d) Connectors:
Connectors are all non-insulated chimney parts including focus black flue,
focus 8"universal adaptor and the chimney manufacturer single wall slip
connector.
To avoid heat traps the chimney connector shall not pass through an attic or
roof space, closet or similar concealed space, or a floor, or ceiling.
Passage through an attic, roof frame floor, or ceiling must be done using an
insulated chimney respecting all chimney manufacturer clearances. For
Canada the installation should conform to CAN/CSA-B365.
CAUTION: PASSAGE THROUGH A WALL OR PARTITION OF
COMBUSTIBLE CONSTRUCTION IS NOT AN APPROPRIATE
INSTALLATION FOR THIS FOCUS FIRE.

Page 6 of 20
Refractory compound must be used to seal each connection. Connectors
should always be in good condition and kept clean. Minimum thickness : 1/32"
(1 mm). Please refer to installation details in this manual.
e) Fresh air intake:
To balance room air pressure with outdoors air pressure, focus recommends
a fresh air intake in the room (ideally emerging under the fire bowl). Fresh air
intake shall only take combustion air from outdoors. We recommend deflect-O
A0684 semi rigid aluminium duct. The appliance is supplied with a fresh air
control. Minimum fresh air intake size:
31 in
2
Ø 6"
fresh air intake
or
Important: this fresh air intake is compulsory when operating venting
appliances such as kitchen hoods, permanent air extractors or any
appliances creating an air depression in the habitation. A lack of air intake
may alarm smoke detectors. Duct maximum length :30 feet (9 meters).

3 –INSTALLATION:
a) Included parts, materials and required tools for installation:
- Appliance and designated parts are the fire bowl, grate, suspended hood,
black steel flue pipe, anchor plate, 4 curved pyroceramic glass screens,
focus kit ( protective glove, mounting gloves, can of touch-up paint), and
insulating washers.
-Required tools: drill, M8 allen key, level, screw drivers, M12 key,
scaffolding, refractory compound.
- 2 persons minimum are required for installation.
b) Options :
• Custom ceiling cover disc (steel disc) + cover-disc screw kit
• Custom anchor steel plate (inclined...)
• Focus black steel flue extension
• Grey paint
• Custom roof outlet in stainless or lacquered steel with insulation and cap
• Fire bowl installation options : recessed into the floor, set above floor level,
or raised on a custom base.
c) Good to know:
• The hood and the fire bowl may not be perfectly and geometrically
centered and aligned due to hood balance position. We strongly recommend
to :
- first install the hood, then find the right position of the fire bowl by installing
the pivoting glasses : the best position is when the glass panels are sliding
smoothly throughout the entire diameter of the track.
- in the event the fire bowl is to be recessed, keep a gap of 1 inch on the
radius to allow the fire-bowl position to be adjusted (recess diameter Ø30-1/2
inches)
- for ease of glass panels installation, the distance between the bottom of the
hood and the finished surface that the fire bowl will sit must be 23-1/32ʼʼ (585
mm).
- The stationary glasses should be installed opposite one another.

4 –OPERATING INSTRUCTIONS :
CAUTION : HOT WHILE IN OPERATION. KEEP CHILDREN, CLOTHING
AND FURNITURE AWAY. CONTACT MAY CAUSE SKIN BURNS.
Never use chemicals or fluids, gasoline, gasoline-type lantern fuel, kerosene,
charcoal lighter fluid, or similar liquids to start or « freshen up » a fire in this
heater. Keep all such liquids well away from the heater while it is in use.
b) Fire-dogs :
The fire-dogs item is located inside the fireplace. It must not be removed
except for cleaning, once all cinders have thoroughly cooled. Fire must only
be built on the fire-dogs.
c) Ashes :
DISPOSAL OF ASHES –ASHES SHOULD BE PLACED IN A METAL
CONTAINER WITH A TIGHT FITTING LID. THE CLOSED CONTAINER OF
ASHES SHOULD BE IMMEDIATELY PLACED OUTDOORS ON A NON-
COMBUSTIBLE FLOOR OR ON THE GROUND, WELL AWAY FROM ALL
COMBUSTIBLE MATERIALS, PENDING FINAL DISPOSAL. IF THE
ASHES ARE DISPOSED OF BY BURIAL IN SOIL OR OTHERWISE
LOCALLY DISPERSED, THEY SHOULD BE RETAINED IN THE CLOSED
CONTAINER UNTIL ALL CINDERS HAVE THOROUGHLY COOLED.
d) Fuel :
CAUTION : DO NOT BURN GARBAGE OR FLAMMABLE FLUIDS SUCH
AS GASOLINE, NAPHTHA OR ENGINE OIL. DO NOT STORE THE FUEL
WITHIN THE SPACE HEATER INSTALLATION CLEARANCES OR WITHIN
THE SPACE REQUIRED FOR CHARGING AND ASH REMOVAL.

Page 14 of 20
Only burn dry, natural, untreated well-seasoned wood. Wood moisture
content should not be more than 20%. We recommend using 2 year dry
stored wood. For the best efficiency use a covered storage. Hazards may
occur with some fuels (e.g., charcoal). Such fuels may generate dangerous
gas like carbon monoxide.
WARNING :
THE WINDOWED FILIOFOCUS HAS BEEN TESTED FOR USE WITH
FOUR GLAZED SCREENS FULLY CLOSED. IF PANELS ARE LEFT
PARTLY OPEN, GAS AND FLAME MAY BE DRAWN OUT OF THE
FIREPLACE OPENING, CREATING RISKS FROM BOTH FIRE AND
SMOKE. TO REDUCE THE RISK OF FIRE INJURY, DO NOT INTEND TO
REMOVE GLAZED SCREENS!
e) Before lighting your first fire :
For all designs it is necessary :
-to remove the stickers from the glass screens (if any).
-to clean off (with a damp sponge and/or a dry cloth) any dirt collected
during transport or installation.
-Actual scratches on painted designs can be retouched solely with the
expressly provided focus can. If this is necessary, ventilate the area
thouroughly before lighting your fire to disperse any fumes generated in
the spraying process. In case of raw waxed models, a tube of « Z »
graphited wax is provided to take care of equivalent minor touch-ups.
The first fire should be a modest one ; do not use packing material or pallet
wood for fuel.
The paint finish we use, oven baked at 250°C for 30 minutes, is thermo-
plastic. Because of the very gradual polymerisation of the components, the
unit may give off a light smoke the first few times the fire is lit. The painted
surfaces nearest the fire may, while hot, acquire a certain viscosity, or slight
stickiness perceptible to the touch. We advise therefore :
-not to be alarmed at possible smoking or residual odors. This is normal
on the first fires and will rapidely subside.
-not to touch, rub or try to clean the fireplace while it is still hot.
To avoid thermal shocks, we strongly advise against throwing buckets of
water on a very vigorous fire to try to put it out.

Page 15 of 20
f) Building, starting and maintaining the fire :
DO NOT OVERLOAD YOUR FOCUS FIREPLACE TO AVOID OVER-
FIRING.
Build the fire without elevating it, directly on the fire-dogs, not too close to the
glasses. For starting the fire, we recommend using a small amount of fire
starter with enough kindling (small logs or mill ends) to establish a primary
fire. Fresh air intake must be fully open (push the handle in direction of the
large side of the triangle, see hereunder illustration) :
After a few minutes, and making sure the primary fire is well started, add
larger wood (between 3 and 7 pieces, depending on their size), directly on
top, making sure not to smother the fire. Leave some spaces between the
logs for air intake. Adapt the air intake position in order to avoid spillage.
To maintain or refuel your fire, add when needed (see note), a few larger
logs.
Note : For the same weight of fuel, 10 logs will burn more intensely (and
faster) than 3 logs, but you will get the same heat power at the end. The log
size you buy will determine the heating and refueling time.

Page 16 of 20
g) Protective glove :
The use of the focus special protective glove supplied with our models is
required upon handling the cold handle, glass panels, fresh air controls, fire-
dogs, etc.
5 –MAINTENANCE :
a) Taking out the ashes:
CAUTION : BE SURE THE FIRE IS OUT AND THE FIREPLACE BODY
COLD BEFORE REMOVING ASHES!
To remove ashes we recommend to remove the fire-dogs and use a brush
and a shovel. Dispose of ashes in an appropriate ash container (not
supplied). After cleaning, be sure to secure the fireplace properly !
CAUTION : DO NOT LIGHT A FIRE WITH FIREDOGS REMOVED, AS THIS
WILL PRODUCE OVER-FIRING OR HOUSE FIRE. DAMAGE CAUSED
FROM NON-OBSERVANCE OF THIS CAUTION IS NOT COVERED
UNDER FOCUS LIMITED WARRANTY.
b) Inspection, maintenance and cleaning of the chimney:
CAUTION : CHEMICAL SWEEP NOT PERMITTED: ONLY MECHANICAL
SWEEP ALLOWED !
Refering to focus black steel flue : it must absolutly be swept with a nylon
brush. Never use metal brushes! Damage caused from non-observance of
this caution is not covered under the focus limited warranty.
Refering to chimney pipe : Creosote formation and need for removal:
When wood is burned slowly, it produces tar and other organic vapors, which
combine with expelled moisture to form creosote. The creosote vapors

Page 17 of 20
condense in the relatively cool chimney flue of a slow-burning fire. As a
result, creosote residue accumulates on the flue lining. When ignited, this
creosote makes an extremely hot fire. The chimney and chimney connector
should be inspected at least once every two months during the heating
season to determine if a creosote buildup has occurred. If a significant layer
of creosote has accumulated (3mm or more) it should be removed to reduce
the risk of a chimney fire.
In that case, call a professional chimney sweeper or buy a brush at your local
focus retailer and clean the chimney this way :
Remove rain cap, use appropriately sized brush and sweep the entire system
to remove all debris or refer to chimney manufacturer recommendations.
Communicate with the authorities (municipal, regional or provincial fire
protection agency) to obtain all instructions concerning the measures to be
taken when or before there is a risk of chimney fire.
Keep firing and de-ashing doors closed and maintain all seals in good
condition.
c) Surfaces :
CAUTION : DO NOT SCRUB !
The outer surfaces can be wiped with a soft, dry rag (making sure the metal is
cool).
For continued use of the touch-up paint can, following its initial usage, invert
the can (spray head down) and spray into a balled up newspaper until the can
sprays clear. Clean the spray can bottom with a dry rag and store out of the
reach of children.
d) Directions and reasons for cleaning glass :
CRACKED OR BROKEN GLASS SHOULD BE REPLACED.
DO NOT CLEAN THE GLASS WHEN HOT.
GLASS DOORS SHOULD NOT BE STRUCK OR BANGED.
The outer surfaces can be wiped with a soft, dry rag and a standard glass
cleaner product (making sure the glass is cool).
The inner surfaces can be cleaned with a special insert glass product.

Appendix.
How to determine if alternate floor protection materials are acceptable.
All floor protection must be non-combustible (i.e., metals, brick, stone, mineral fiber
boards, etc.). Any organic materials (i.e., plastics, wood paper products, etc.) are
combustible and must not be used. The floor protection specified includes some form of
thermal designation such as R-value (thermal resistance) or k-factor (thermal conductivity).
PROCEDURE:
1. Convert specification to R-value:
i. R-value given - no conversion needed.
ii. k-factor is given with a required thickness (T) in inches:
T
k

R!=
iii. K-factor is given with a required thickness (T) in inches:
T
12xK
1
R!=
iv. r-factor is given with a required thickness (T) in inches:
R = r x T
2. Determine the R-value of the proposed alternate floor protector.
i. Use the formula in step (1) to convert values not expressed as “R”.
ii. For multiple layers, add R-values of each layer to determine overall R-value.
3. If the overall R-value of the system is greater than the R-value of the specified floor
protector, the alternate is acceptable.
EXAMPLE: The specified floor protector should be 3/4-inch thick material with a k-factor of
0.84. The proposed alternate is 4” brick with an r-factor of 0.2 over 1/8” mineral board with
a k-factor of 0.29.
Step (a): Use formula above to convert specification to R-value.
