4 OPERATING INSTRUCTIONS:
CAUTION: HOT WHILE IN OPERATION. KEEP CHILDREN, CLOTHING
AND FURNITURE AWAY. CONTACT MAY CAUSE SKIN BURNS.
a) Storage/use of flammable liquids:
Never use 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) Grate:
The cast-iron grate 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 grate.
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 PLACED 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.
Only burn dry, natural, 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.
Page 16 of 21
WARNING: THIS FIREPLACE HAS NOT BEEN TESTED FOR USE WITH
DOORS, TO REDUCE THE RISK OF FIRE INJURY, DO NOT INSTALL
DOORS!
e) Before lighting your first fire:
For all designs it is necessary:
- 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 rapidly 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 17 of 21
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 grate. 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.
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.
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.
g) Protective glove:
The use of the focus special protective glove supplied with our models is
required upon handling the damper, fresh air controls, fire irons, etc.
Page 18 of 21
5 MAINTENANCE:
a) Taking out the ashes:
CAUTION: BE SURE THE FIRE IS OUT AND THE FIREPLACE BODY
COLD BEFORE REMOVING ASHES!
The ash removal hatch located below the grate is designed to make cleaning
easier. Dispose of ashes in an appropriate ash container (not supplied). The
hatch is removed by turning the handle. After cleaning, be sure to secure the
hatch back properly!
CAUTION: DO NOT LIGHT A FIRE WITH ASH REMOVAL HATCH
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) 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
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.
Page 19 of 21
c) Sweeping your chimney:
CAUTION: CHEMICAL SWEEP NOT PERMITTED: ONLY MECHANICAL
SWEEP ALLOWED!
The focus black steel flue, stainless steel flue liner or insulated flue chimney
system absolutly must be swept with a nylon head sweeper. Never use metal
head sweepers! Damage caused from non-observance of this caution is not
covered under focus limited warranty.
d) 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 focus 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.
In case of raw waxed models, the tube of « Zebraline » graphited wax is
provided to solely look after your fireplace . You must wax it twice a year or
more if needed. Remember the graphited wax will keep your fire out of rust

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.

proposed system Rtotal is greater than required, the system is acceptable.
