This stove must be connected to a standard 120V / 60Hz, grounded electrical outlet. Do not use
an outlet adapter, an extension cord or sever the grounding plug. Do not route the electrical cord
underneath, in front or over the stove.
It is important that adequate oxygen is being supplied to the fire for proper combustion. At all time,
make sure the outside air register is not obstructed by ice, snow or other objects as this will starve the
fire of air and prevent the proper operation of the stove.
Mixing of appliance components from different sources or modifying components is prohibited and
will void the warranty.
Any modification to the stove that has not been approved in writing by the testing authority is prohibited
and violates CSA B365 (Canada), and ANSI NFPA 211 (USA).

2 Recommended heating area and maximum burn time may vary subject to location in home, chimney draft, heat loss factors, climate, fuel type, feed
rate, fuel level, and other variables.The recommended heated area for a given appliance is dened by the manufacturer as its capacity to maintain a
minimum acceptable temperature considering that the space conguration and the presence of heat distribution systems have a signicant impact
in making heat circulation optimum.
3Mobile home (Canada) or manufactured home (USA): The US department of Housing and Urban Development describes “manufactured homes”
better known as “mobile homes” as followed; buildings built on xed wheels and those transported on temporary wheels/axles and set on a
permanent foundation. In Canada, a mobile home is a dwelling for which the manufacture and assembly of each component is completed or
substantially completed prior to being moved to a site for installation on a foundation and connection to service facilities and which conforms to the
CAN/CSA-Z240 MH standard.

Certification Label
Since the information given on the certification label affixed to the stove always overrides the
information published in any other media (owner’s manual, catalogues, flyers, magazines or web sites),
it is important to refer to it in order to have a safe and compliant installation. In addition, important
information about the stove can be found (model, serial number, etc.). The certification label is located
on the inner side of the hopper lid of the stove.

FUEL
Recommended Pellets
Type: Wood pellet, premium grade or better, certified by PFI, Enplus or CANplus.
Size: Diameter between ¼" or 5/16" and not over 1" long. Longer or thicker pellets will affect the
constancy of pellet feed. The pellets length may vary from one lot to another, even if it comes from the
same manufacturer.
Short pellets Long pellets
Ash contents: Less than 1%. Ash contents more than 1% will increase maintenance frequency, create
combustion problems and will increase the stove emission.
Moisture content: Wet pellets will be very hard to ignite and will greatly affect the feeding process of the
stove. Using dry pellets will maintain the performance of your stove.
Note that the pellets quality may vary depending on the manufacturer. It can also vary from
one bag to another, even if it comes from the same manufacturer. It is recommended to
try several different manufacturers to find the one that best suits your use. Then, buy the
pellets in lots of several tons to ensure satisfaction.
Burning other types of pellets is prohibited. It violates the building codes for which the
stove has been approved and will void the warranty.
Storage
Pellets should remain in their original packaging until ready for use.
Pellets bags should be stored in a dry and well ventilated area, if possible. If they are to be stored
outside, remember that pellets bags are not water tight. It is best to keep the pallet wrapper as intact
as possible and cover it with a tarp.
Having a bag or two in the same room as the stove for refueling is a good idea. The minimum
clearances to combustible materials and the space required for refilling and ash removal needs to be
respected.
DO NOT STORE FUEL WITHIN STOVE MINIMUM CLEARANCES TO COMBUSTIBLE.
