STRUCTURAL REQUIREMENT
CAUTION
THE SUPPORT OF THE ANCHOR PLATE (ROOF STRUCTURE, SLAB, ETC.) AND OF THE STATIONARY PLATE 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.
CONNECTOR
Connectors are all non-insulated chimney parts including focus black flue, focus 8” universal adaptor and the chimney
manufacturer finishing collar with adapter.
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.
CAUTION
PASSAGE THROUGH A WALL OR PARTITION OF COMBUSTIBLE CONSTRUCTION IS NOT AN APPROPRIATE
INSTALLATION FOR THIS FOCUS FIREPLACE.
FRESH AIR INTAKE
For optimum functioning, focus requires a fresh air intake in the room (ideally under the stationary plate). We recommend
deflect-O A0684 semi rigid aluminium duct. The fire bowl is supplied with a fresh air control.

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 Ø32-1/2 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 19-5/16” (490 mm).

Installation
Replacement : Allow the fireplace to cool before removing or replacing glass. Use caution when removing broken glass to prevent
injury. Do not apply any force on the glass as this may cause breakage. To remove a glass, first remove the fire bowl. Then lift the
first sliding glass up so it can get out of the base rail. Now push gently the base of the glass in order to move it in direction of the
center of the fireplace. The top of the glass will then get out of the hood rail ; Proceed the same way for the stationary glass pannels.
F. GLASS INSTALLATION / REPLACEMENT
Installation: Use caution when manipulating glass to
prevent injury. Do not apply any force on the glass as this
may cause breakage. Please check the hood level to be
490 mm (19-5/16’’) from stationary box support level. The
meijifocus receives 5 glass panels : 3 stationary and 2
sliding on track. To fit a glass panel, first remove the fire
bowl for easier access. Then present the glass panel botom
first, inclined as illustrated on the hereunder image.
The top left and right corners must be presented and
adjusted to penetrate into the hood rail. External rail is for
sliding panels, internal rail is for the stationary panels. Slide
up the panel and rotate it gently so it gets its position vertical
again. Then just slide down the panel in order to secure it in
the stationary box track.
Each stationary glass panel should be gently secured to the
hood internal ring using the supplied offset retention clips
and knurled bolts.

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.
FIRE BOWL
The fire bowl is located inside the fireplace. It is equiped with as fresh air intake control. To adjust fresh air intake, rotate the
fire bowl in the way to open or close the air openings. Fire bowl must not be removed. Fire must only be built on the fire bowl.
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, 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
The meijifocus has been tested for use with glazed panels fully closed. If door is open or 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 remove glazed panels!

12
Operating instructions
BEFORE LIGHTING YOUR FIRST FIRE
For all designs 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.
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.
Do not use chemicals or fluids to start the fire.
Do not operate with broken glass.
Do not build the fire too close to the glass.
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.

13
PROTECTIVE GLOVE
The use of the focus special protective glove supplied with our models is required upon handling the damper, glass panels, fresh
air control, 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 Meijifocus 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.
Operating instructions

14
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 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!
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 CHIMNEY AND CHIMNEY CONNECTOR MUST BE IN GOOD CONDITION AND KEPT CLEAN
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..
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.
DO NOT SCRUB !
DO NOT USE ABRASIVE
CLEANERS !
CAUTION
Maintenance

15
DIRECTIONS AND REASONS FOR CLEANING GLASS
Cracked or broken glass should be replaced. Do not clean the glass when hot.

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.
