OPERATING THE FIREPLACE 9
When the outside air control is down, the outside air damper is open. When it is up, the outside air
damper is closed. Use a gloved hand to adjust the air control when the fireplace is hot.
From the open position, push it gently to the right and then slide up to release it. A spring will keep it
closed. From the close position, just push it down passed the notch that will keep it open. It will not
change position by itself.
Even though the fireplace can be operated with the outside air damper closed, we recommend always
using outside air for combustion when burning the fireplace with the glass door closed. In some cases
this fresh air will also help compensate for negative pressure problems within the house (for example,
when strong kitchen or bath fans compete with and reduce chimney draft in a tightly constructed
house); however it will not prevent the fireplace from smoking in a severely depressurized house.
We also recommend using outside air for combustion when burning the fireplace with the firescreen
closed. It will help reduce the depressurization of the house caused by burning the fireplace with the
firescreen (when the fireplace draws large amounts of air from within a tightly constructed home).
This control should, however, be closed when the fireplace isn’t burning to prevent cold air infiltration. It
is sealed with a gasket.

The LINEAR 50 is equipped with a chimney damper that is located in the flue at the top of the fireplace.
This chimney damper should only be used in either fully open or fully closed position. The chain for
the chimney damper is inside the firebox at the front, just above the opening.
When you secure the damper closed (pulling the chain down) it will virtually eliminate the flow of warm air up the
chimney as well as prevent cold air from entering from outside. The damper is counter-balanced and will open by
itself when you un-hook the damper chain. See Figure 3.
BUILDING THE FIRE
Always start by opening the chimney damper.
There are a number of ways to arrange your firewood to build a fire in your LINEAR 50. Always build and maintain
the fire well behind the ash step refractory bricks, never against or close to the glass door or the firescreen. In all
cases, you want to start with a number of pieces of easily lit material, such as newspaper. Place pieces of crumpled
or loosely knotted paper in the area where you will be placing the kindling and firewood. Then add a generous layer
of kindling over the paper, placed with spaces between the pieces for air flow. Finally, stack 2-3 small-medium size
logs over the kindling so that they are close or touching one another, but have small spaces between them for air
flow. Then light the paper in a number of places and close the firescreen. Keep burning with the firescreen closed for
at least the first 30 minutes after lighting the fire. Once the fire is established, you can add more wood and close the
glass door or the firescreen, as you prefer. Either the glass door or the firescreen should always be closed when the
