VENTILATION
Air introduction to stove happens in three locations:
1. The Lower Primary Air Orifice (LPAO), behind the
door.
2. The primary air inlet.
3. The secondary stage air tubes.

• By pushing the air control (on the front of the
stove) into the stove the primary air inlet hole at the
back of the stove is closed.
• Pulling the primary air inlet air control away from
the stove increases the size of the opening for air
to enter the firebox.
In general, the further the air control is pulled out
the hotter the stove will get. The best position for the
air control will depend on the chimney specifications,
weather, and fuel.
In order to find the best position for the air control
in your installation, start a stove fire as this manual
details. For 15 to 20 minutes have the air control pulled
away from the stove to fully open the Primary Air Inlet.
At the secondary air combustion (top of the firebox)
you should be able to observe a secondary combustion
taking place. Push the air control in towards the
stove to the desired heat setting. If the secondary
combustion disappears, restart it by pulling the air
control away from the stove. Move the air control to
the desired heat setting by gradually pushing it in and
ensuring that secondary air combustion is still being
supported. Secondary air combustion is important for
maximizing the heat transfer from the stove to you and
minimizing the amount of smoke which can condense
within your chimney as creosote.
NOTE: SECONDARY COMBUSTION MINIMIZES,
BUT DOES NOT ELIMINATE, CREOSOTE

WARNING:
should be provided from the outdoors if
these or other indications suggest that

or not there is combustion present.
• Existing fuel-fired equipment in the
house, such as fireplaces or other
heating appliances, smell, do not operate
properly, suffer smoke roll-out when
opened, or back-draft, whether or not
there is combustion present.
• Any of the above symptoms are
alleviated by opening a window slightly
on a calm (windless) day.
• The house is equipped with a well-sealed
vapor barrier and tight fitting windows
and/or has any powered devices which
exhaust house air.
• There is excessive condensation on
windows in the winter and
• A ventilation system is stalled in the
house.
CHIMNEY DRAFT CONSIDERATIONS
Draft is the force which moves air from the appliance
up through the chimney. The amount of draft in your
chimney depends on the length of the chimney, local
geography, nearby obstructions and other factors. Too
much draft may cause excessive temperatures in the
appliance. Inadequate draft may cause backpuffing
into the room and 'plugging' of the chimney or the
catalyst.
Inadequate draft will also cause the appliance to leak
smoke into the room through appliance and chimney
connector joints.
An uncontrollable burn or excessive temperature
indicates excessive draft.
Please be mindful of installation location: Inversion and
other air quality issues can arise in valleys or if unit is
installed close to neighboring homes. To achieve and
maintain the draft:
• After the fuel has burned out and you are finished
with the stove, open the Primary Air Inlet all the way
by pulling the air control away from the heater.
• Obey all chimney requirements,
page 12.
• Seal any and all connections of intake and exhaust
piping.
