OUTSIDE MAKE-UP AIR FOR COMBUSTION IS REQUIRED ON ALL INSTALLATIONS
1) For FREESTANDING installations with horizontal through-the-wall exhaust, it is REQUIRED that
the stove combustion air intake be connected to a fresh air intake outside. If the home is newer or has
been tightly insulated it is imperative to the operation of the unit to install outside combustion air. If
you do not, then an additional 6 inch intake into the furnace room in the basement is required.
2) For INSERT installations into an existing fireplace, or FREESTANDING installations with a vertical
exhaust, outside air connection is required.
3) Connection to outside the house is REQUIRED for mobile home installations.
IMPORTANT: It is the customer’s responsibility to make sure that there is adequate fresh air to
the home so that the MagnuM Countryside appliance does not become the fresh air source.
4) Only non-combustible pipe 3 inches in diameter is approved to use for outside air connections
(straight or flexible). PVC pipe is NOT approved and should NEVER be used.
5) If the air inlet is connected to the outside, it MUST be terminated with a vertical 90-degree bend
(down) or with a wind hood. Failure to do so could result in a burn back during high winds blowing
directly up the air inlet during a simultaneous power failure (see diagram above).
6) It is important not to terminate the inlet of the fresh air intake too close to the venting outlet for the
smoke. It is recommended that the inlet for the fresh air is a minimum of 3 feet away from the venting
outlet and at least 2 feet below.
7) Blockage, excessive length, or bends in the air intake pipe will starve the stove of combustion air. A
90-degree bend is equivalent in restriction to approximately 30 inches of straight inlet pipe.
