and easily reachable for future references. Not following these instructions could be a
cause of property damages, injuries or death. If this appliance is not properly installed, it
could cause fire damages to the property, injuries and death. To reduce fire hazards,
follow instructions contained in this handbook.
Contact an official inspector (ex: a fireman) or your insurance company for installation
permit. Always respect the provincial and municipal building codes of your region.
Do not connect this appliance to a chimney that already serves for another wood
appliance.
Do not install the appliance in a mobile house.
The existing chimney should be well inspected before any installation. In doubt, consult a
specialist.
The room where the appliance must be installed must measure a minimum of 64 ft
2
and
must be very well ventilated.
Minimum clearances found in this manual must be observed.
Never use a non-isolated exterior conduct or a single wall flue pipe as an exterior exit.
Put in place the firebricks before lighting the appliance (if they are not in place yet).
WARNING : Very hot while in function
 Keep children far away from the appliance.
 Never let the appliance without supervision when the door is open.
 Always close the doors after the lighting period.
 Do not use chemical products or other liquid to light the fire.
 Do not burn waste or inflammable fluids like gas, naphtha or motor oil.

etc...) at a minimal distance of 91,5 cm (3 feet) from the appliance.
This appliance is certified to burn wood. Do not use any other combustible.
Wood should not be stocked within the recommended minimums clearances or in the
necessary space for the loading and the ashes evacuation.

6
Always use dried wood. Do not burn green or wet wood. Do not use construction debris
such as pieces of 2x4, plywood...
If the appliance starts to blush, it's because it is too charged. Do not add fuel.
Immediately close the doors and the air intake of the appliance until everything becomes
normal again.
Do not load the appliance beyond the firebricks height.
Ashes must be evacuated frequently, put in a steel container provided with a tight lid and
be placed outside at once. You must never place other waste in this container.
Considering the need of air for the combustion, a window or a door must be half opened
sometimes (fresh air drainage) to balance the pressure in the house, especially if:
- A fan already evacuates air towards outside (kitchen, bathroom.)
- You want to avoid a repression of smoke when lighting the appliance and when
reloading the wood.
It is recommended to have a smoke detector near the appliance.
You should contact your municipal or provincial fire department to have knowledge
of the procedure to be followed in case of a chimney fire. Think of an emergency
plan.
In case of a chimney fire:
- Hermetically close the doors and the air intakes.
- Water the combustible material adjacent to the chimney.
- Ring the alarm, evacuate the house if necessary and call the firemen.
- Never touch the pipes until the fire is not completely extinct.
- Do not use the chimney until it has been inspected or repaired.
Keep all the doors closed while the appliance is in function. Frequently verify the
ceramics cords, they must always be in good condition.
The chimney pipe should not pass close to water, gas or oil pipes, nor close to electric
wire or other types of conduits, of combustible materials in the roofs, the attics, the walls
or the floors. If you have to make it pass through a wall or a part of combustible
construction, do not forget that the installation must be in accordance with the
CAN/CSA-B365. Use at least 12 feet of a 7 inches diameter vertical chimney.
NOTE:
FOLLOW THESE INSTRUCTIONS IN ORDER TO AVOID FIRE HAZARDS,
WOUNDS AND PROPERTY DAMAGES.

NOTICE
The Atmosphere furnace 727 was conceived to safely function the doors closed and only
when burning firewood. Any change, modification or unauthorized installation will
automatically cancel the certification of the appliance, its guarantee, its homologation and
the appliance might become dangerous.
During the first hours of operation, you must heat it gradually. In order to allow an
appropriate cooking of the paint and in order to facilitate its adhesion with metal, do not
heat the appliance with a strong fire. It will also avoid thermal shock which could lift up
the paint or make it whiten.
Make sure that the room is ventilated enough in order to eliminate the odours and the
smoke coming from the paint during the first hours of utilization. It is normal that a light
smoke is released from the paint during the first hours of use.
Even if this nuisance is temporary, open the windows and the doors in order to ensure a
good ventilation. This special paint is conceived to tolerate temperatures until 1200°F
(650°C).
C REOSOTE
The wood burning slowly produces tar and other organic steams, which forms a whole
called “creosote”. The steam condenses in the cool chimney when the wood is burning
slowly. In this way, creosote residues are formed on the walls. Creosote can take several
forms: tarry liquid, soot dust or deposits in crystal form. When in fire, the creosote
releases a very strong heat and can be the cause of a chimney fire.
- Do not knock on the glasses or violently close the doors.
- Do not use the appliance when a glass is broken or damaged.
- Do not build the fire too close of the glasses.
- Keep the doors closed when using the appliance.
- Do not connect the ATF 727 with a chimney or a flue serving another heating
appliance

8
CHIMNEY
Only use approved chimneys of the same dimensions as the appliance exit. Therefore,
you should use 7 inches diameter chimneys for your Atmosphere furnace 727. Chimneys
must be tested upon the ULC S629 CSA, UL103 norms. The Atmosphere furnace 727
wood appliance can be installed onto a masonry chimney following the ULC S635, ULC
S640 and the UL 1777 norms. Do not forget to plan a place for the sweeping of the
chimney.
When possible, it is preferable to avoid an outside chimney or built on an exterior wall,
and this is even more important for colder areas. Outside chimneys generally have a less
efficient draught. They can even have an inverse draught because it is hard to heat them
enough so that they can reach their operating temperature. A greater accumulation of
creosote, a less efficient draught and a lesser performance are some characteristics of cold
chimneys. Draught is proportional to the total chimney height as well as its temperature.
It is therefore possible to get a better draught by increasing the chimney's height and by
reducing the heat loss with an insulated lining. The chimney has to be installed with a
stainless steel lining. Make sure that all smoke pipe joints are really airtight. A leak
reduces the efficiency of the appliance and could even make its utilization dangerous.
INSTALLATION
A good installation is extremely important for a safe and efficient use of your J.A. Roby
Inc. appliance. If you doubt on the way to install the appliance correctly, seek for
professional installation service. We suggest you to call masters fitters.
1. Withdraw firebricks placed inside the appliance in order to reduce the weight and
to facilitate the installation.
2. You must install a fireproof plate under the appliance, which must exceed of 18
inches at the front and of 8 inches at each side.
3. The option of 4 round exits of 6" diameter or 2 round exits of 8" diameter is
allowed for an installation after the plenum by respecting pressure and air volume.
4. The free space shall not be reduced except under the approval of the authorities
responsible for the application of the building code.
5. Install the chimney and an insulated wall firebreak for an installation passing
through a wall according to the instructions from the chimney manufacturer.
6. Install the firebricks in accordance with the recommended instructions for your
model.
7. The appliance should not be connected to an hot air conduct.

CLEARANCES
Due to its reduced clearances, this appliance occupies a minimum of space in the room
where it is installed. No matter where you install it, this appliance will perfectly complete
your decoration by its originality and its heat. This appliance only needs a 12 inches
clearance at its back, 12 inches from the lateral walls and 18 inches from the ceiling. For
the plenums and heat exchanger, the clearances must be of 6 inches for the 6 first feet and
of zero thereafter.
If you place the plenums (4 exits of 6 inches or 2 exits of 8 inches plenums) in front of
the appliance, do not place the safety thermodisc under the plenum. The door's heat may
stop the appliance and the fans may not restart when the electricity returns; the
thermodisc being too hot.

13
INSTALLATION OF THE FIREBRICKS
To begin with, you must consider that the screw which will fix the bottom bricks and the
one which will fix the lateral bricks are partially screwed and that the stainless pipes (4)
are installed. There are three (3) pipes model #1 and 1 pipe model #2.
Stages :
1. Install the first row of bricks (stand up) on the lateral sides (5 on each side).
2. After that, install the ten bricks at the bottom of the appliance. Take care to push
them against the bottom wall.
3. Install the two small bricks on each side.
4. Then, install the four bricks in the stand up position and press them against the
bottom wall (Do not screw immediately).
5. Install the bricks on each lateral sides (3 in the larger position as illustrated) and
install the two bricks on the bottom wall.
6. Screw all the screws but don't tighten too much in order to avoid the blow up of
the bricks.
7. Place the bricks support on the top and be sure that it is centered.
8. Install the eight top bricks (over the bricks support).
* Be sure that they are centered and place them against each other. (Pass the
bricks by the chimney hole).

14
FANS AND THERMODISC
The 115 volts fans must be screwed under the ventilation conduct at the planned place in
the appliance rear. The protection thermodisc box must be fixed at 72 inches (182,88cm)
from the appliance on the ventilation conduct. A hole must be done in order to permit the
air coming from the fans to touch lightly the thermodisc. Plug the terminal.
When the appliance is in function, the heat reaching a temperature of 120oC activates the
thermodisc. At this moment, the thermodisc activates the fans for a better distribution of
heat in your home. As soon as the heat goes under 120oC, the thermodisc automatically
stops the fans.
When the appliance is in fonction, and that the protection thermodisc fixed on the
ventilation conduct reaches a temperature of 160
0
F, the thermodisc will stop the fans and
will close the air entry in order to slow down the combustion and will stop distributing
the heat in the ventilation conduct of your home. When the heat goes under 160
0
F, the
thermodisc will automatically allow the air entry openning and will start the fans.
If you use the appliance without thermostat, see the section named “ In case of extended
electric failure”
The electrical cord of the fans must never touch the appliance surfaces in order to
avoid electrical shock or fire.

18
SEATING
You must install a fireproof plate under the
appliance, which must exceed it of 18 inches
to the front, of 8 inches to the sides and of 8
inches at the back.
**** Use only non-combustible materials
such as ceramics, marble or granite.
LIGHTING
Now that you have completed the installation of the appliance according to the
recommendations, you are ready for the lighting!
1. Place papers and small wood in the appliance.
2. Before lighting, be sure that the chimney is warm enough.
3. When the fire is well lit, gradually add bigger wood logs until an ember bed is
formed.
4. You can then control combustion by closing or opening the air intakes (a rod
pulled down indicates a closed air intake). The wood will burn more quickly if the
air intakes are opened to the maximum and more slowly if they are only slightly
open.
Do not charge the appliance beyond the bricks .

19
AIR CIRCULATION OF THE HEATING SYSTEM
Always refer to the applicable building code before installing the hot air conduct.
It is recommended to install a floor screen in order to balance the air pressure between the
floor where the appliance is installed and the superior floor. It is also recommended to
install those floor screen to each home extremity.
An air supply must be installed if :
a) The appliance seems to have an irregular draft control, a smoke return, a bad
combustion and a counter-blow even though you have a combustion or not.
b) Your other appliances, such as hearths or other heating appliances, release odors,
heat badly, provoke smoke return or a counterblow, even though there is
combustion or not.
c) An opened window, even slightly, by a calm temperature (without wind) stops the
situation above.
d) Your home was built with isolated dandruffs and with well adjusted windows,
and/or was built with a mechanism to evacuate the interior air.
If, with these indications, there is not enough air infiltration, you must ensure an air
supply.
In doubt, it is recommended to ensure an air supply.
Hot air pipe : 8" diameter for 20 feet length.
6" diameter for 15 feet length.

20
IN CASE OF EXTENDED ELECTRIC FAILURE
Lift up the stem of the air intake and make it slip towards the interior so as to align its
holes with the holes at the front of the appliance, allowing a contribution or a reduction of
air, according to the needs. To measure out the air entry in the combustion chamber, you
have to rotate the handle; upwards for an opening and downwards for a closing It is
important to lower the ventilation
door at the front so that heat can
spread out in the room. The
appliance will become much hotter
without the circulation of air
coming from the fans; thus the
ceilings, the walls and everything
around the appliance will be
exposed to an higher heat than
normal.
AIR SUPPLY
A new air supply can be done by the following ways:
Indirect method : In the case of an appliance not certified for a direct connection with a
source of new air supply, the new air is brought in a conduit at a maximum of 300mm (12
Po) of the appliance, in order to not compromise its operation.
Mechanic ventilation system : If the home is built with a ventilation system (air
exchange or heat recovery)
I. The ventilation system might be able to supply an efficient air quantity to a solid
combustible appliance, and
II. The owner should be informed that the ventilation system can have to be
rebalanced by a technician specialised in ventilation after the installation of the
solid combustible appliance..
