Fresh Air Intake Kit - Ventus ME300 Installation And Operation Manual

3.9 Fresh Air Intake Kit
During operation, the fireplace requires fresh air for combustion and draws air out of the house. It may
starve other fuel burning appliances such as gas or oil furnaces. As well, exhaust fans may compete for air,
causing negative pressure in the house, resulting in smoke entering the house from the fireplace. This
situation is aggravated in modern airtight houses. To overcome this problem, we strongly recommend that
you bring fresh air to the fireplace. Check with local authorities having jurisdiction in your area, it may be
mandatory.
THE INSULATED FLEXIBLE PIPE LENGTH SHOULD BE SUFFICIENT AND HAVE A CONFIGURATION TO AVOID
CONDENSATION.
THE OUTSIDE WALL TERMINATION MUST NOT BE INSTALLED AT MORE THAN 50% OF THE TOTAL HIGHT
OF THE CHIMNEY AND AT THE MOST 10 FT. (3 M) ABOVE THE BASE OF THE FIREPLACE.
THE FRESH AIR MUST COME FROM OUTSIDE THE HOUSE. THE AIR INTAKE MUST NOT DRAW AIR FROM
THE ATTIC, FROM THE BASEMENT, OR FROM A GARAGE.
THE OUTSIDE WALL TERMINATION SHOULD BE INSTALLED WHERE IT IS NOT LIKELY TO BE BLOCKED BY
SNOW OR EXPOSED TO EXTREME WIND AND AWAY FROM AUTOMOBILE EXHAUST FUMES, GAS METER
AND OTHER VENTS.

To complete the fresh air installation, you will need a 4" insulated flexible pipe. Use the length required for
your installation while respecting the maximum length of 30 ft (9 m). To avoid condensation, it is
recommended to use an insulated pipe long enough and containing a "P‐Trap" loop. This configuration can
be found inside the chase, but must at all times maintain clearances to combustibles.
Remove the knock out (A) located on the left‐hand side of your fireplace. Then cut and remove the
