Monaco Installation and Operation Manual
Appendix 3: Installing the Optional Adapter for Fresh Air Kit
(AC03500)
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.
If more fresh air is needed (airtight house or conduit exceeding 10 ft or 3 m), two intakes
may be installed, providing twice the quantity of incoming fresh air; you may also increase
both conduits to 4 inches, with the use of a 3 to 4 inch adaptor, again increasing
substantially the quantity of incoming fresh air.
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.
