Operating instructions
CAUTION
HOT WHILE IN OPERATION. KEEP CHILDREN, CLOTHING AND FURNITURE AWAY. CONTACT MAY CAUSE SKIN BURNS.
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.
GRATE
The 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.
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.
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 REFUELING AND ASH REMOVAL.
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.
WARNING
THIS FIREPLACE HAS NOT BEEN TESTED FOR USE WITH DOORS, TO REDUCE THE RISK OF FIRE INJURY,

BEFORE LIGHTING YOUR FIRST FIRE
For all focus models it is necessary:
• To remove the stickers from the glass panels (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 paint. If this is necessary,
ventilate the area thouroughly before lighting your fire to disperse any fumes generated in the spraying process.
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.

Operating instructions
BUILDING, STARTING AND MAINTAINING THE FIRE
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.
Do not overload your focus fireplace to avoid over-firing.
Build the fire without elevating it, directly on the grate. 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 (pull the handle towards you) as for damper (handle vertical).
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.
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 controls, fire irons, etc.
DAMPER OPERATION AND USE
Use of supplied cold handle tool or protective glove is recommended to operate the damper. Do not touch the damper handle without
protection when a fire is operating.
The Emifocus damper has four positions. The damper is in the same direction as the handle: when the handle is vertical, the damper
is fully open. Handle can rotate at 30°, 60° and 90° (horizontal : closed). In closed position the damper obturates by 75% the flue
section. To modify the damper position, first pull the handle, then rotate and push again
the handle in order to lock on a preset position.
CAUTION
NEVER ADJUST THE DAMPER HANDLE ON AN INTERMEDIATE POSITION !
The damper position must be adapted to the fire intensity : during the lighting it must be fully open. Then it must be adjusted in order
to reduce the smoke flow, so the heat efficiency will be optimal. If the smoke spills out it means the damper is too obstructive : re-
open the damper at the first signs of spillage.

15
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!
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.
SWEEPING YOUR CHIMNEY
CAUTION
CHEMICAL SWEEP NOT PERMITTED: ONLY MECHANICAL SWEEP ALLOWED!
The focus 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..

Maintenance
SURFACES
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.

Annex
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).
A. 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:
III. K-factor is given with a required thickness (T) in inches
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.
Step (b): Calculate R of proposed system.
4” brick of r = 0.2, therefore:
1/8” mineral board of k = 0.29, therefore
Rtotal = Rbrick + Rmineral board = 0.8 + 0.431 = 1.231
Step (c): Compare proposed system Rtotal of 1.231 to specified R of 0.893. Since proposed system Rtotal is greater than
required, the system is acceptable.
