A source of air (oxygen) is necessary in order for combustion
to take place. Whatever combustion air is consumed by the
fire must be replaced. Air is replaced via air leakage around
windows and under doors. In homes that have tightly sealed
doors and windows, an outside air source is needed. An optional
Outside Air Kit is available.
WARNING
Do not draw outside combustion air from:
• Wall, floor or ceiling cavity
• Enclosed space such as an attic or garage
• Close proximity to exhaust vents or
chimneys
Fumes or odor may result
Fire Risk.
Asphyxiation Risk.
Asphyxiation Risk.
Outside air inlet must be located to prevent block-
age from:
• Leaves, snow, ice or other debris
Block may cause combustion air starvation
Smoke spillage may set off alarms or irritate sensi-
tive individuals.
WARNING
Asphyxiation Risk.
Length of outside air supply duct shall NOT exceed
the length of the vertical height of the exhaust flue.

Option One - Installation Instructions
The outside air cover comes packaged with the component
pack. It is necessary to remove the blower housing and block
off the room air with the outside air cover.
1. Remove the appliance cover plate on outer can and discard
and reuse the 4 screws.
2. Install optional flex adapter to outer can with the same
screws. Do not use plastic wire ties that come with the kit
as they will melt. NOTE: You may need to install the flex
pipe into the firebox first depending on installation. Attach
flex to adapter with at least 2 screws.
3. Ensure existing access hole in fireplace is sufficient to feed
the 4 inch flex.
4. After sliding can into fireplace, feed flex into cut opening to
obtain outside combustion air.
5. Level outer can and install appliance. See
page 18.
6. Remove 4 bolts from both sides of the blower housing and
remove the housing.
7. Remove 2 Phillips head screws from housing and save.
8. Attach outside air cover to the back of the blower using the
same 2 screws.
9. Ensure all wires are properly attached and then re-install
the blower housing to the appliance.
Option Two - Installation Instructions
1. Remove the outside air cover plate on outer can and dis-
card and reuse the 4 screws
2. Ensure existing access hole in fireplace will not be covered
by the outer can. Existing outside air intake hole may be
under at the rear or side of outer can. Outside air may also
enter down existing chimney chase in some situations.
3. Repeat steps 5 through 9 above with one exception. After
installing the appliance in the outer can, seal the fireplace
opening and trim package with insulation to prevent air leak-
age into the room.
