Outside Air Connection; Chimney Connector - England's Stove Works 28-4000 Guide D'installation Et D'utilisation

Outside Air Connection

It is recommended, especially in air-tight homes, to supply the combustion air into
the unit from outside the dwelling. This can be done by running a thin gauge 3-inch (76.2
mm) pipe (flex or rigid) from the air inlet pipe located on the rear of the stove through the
floor or wall (measure pipe to ensure you obtain the correct size). The outside end of this
pipe should be covered in some manner (i.e. screen) to keep it clear of foreign matter. Be
sure to keep it above the snowdrift line and clear of leaves and other debris. If you are
installing this stove in a regular dwelling this connection is not necessary, but is
recommended in air-tight homes.
With ANY installation, it will be necessary to have at least some length of pipe
connected to the air inlet. It should be long enough to reach past the blower that is on the
rear of the furnace, or the blower will interfere with the furnace's intake air and make it
difficult, if not impossible, to maintain a fire.
A kit is available from England's Stove Works, Inc. designed for connecting this unit to
outside combustion air. [Part No. AC-OAK3]
Outside combustion may be necessary if:
1. The furnace does not draw steadily, smell, experiences smoke roll-out,
burns poorly, or back drafts whether or not there is combustion present.
2. Any of the above symptoms are alleviated by opening a window slightly
on a calm day.
3. The house is equipped with a well-sealed vapor barrier and tight fitting
windows and/or has any powered devices which exhaust house air.
4. There is excessive condensation on windows in the winter.
5. A ventilation system is installed in the house.
Chimney Connector Pipe
This black pipe must be 6 inches (152.4 mm) in diameter and a 24-gauge or
heavier pipe. Do not use aluminum or galvanized steel, as they cannot withstand the high
temperatures of a wood fire. Do not use single wall pipe as a chimney. You must connect
your stove to a chimney comparable to those illustrated in this manual. The chimney
connector pipe lengths must be attached to the stove, and to each other, with the crimped
end toward the stove. This will allow any creosote that might form to remain within the
pipe. As a safety precaution, all joints should be sealed with high temperature silicone
(AC-RTV3) and secured with three sheet metal screws. For proper operation, the
chimney connector should be kept as short as possible. Horizontal lengths of chimney
connector pipe should never exceed 6' (6 feet; 1.82 m) and should have an upward slope
of ¼" (one-quarter inch; 6.35 mm) per foot (304.8 mm).
Maintain at least 18 inches (457.2 mm) clearance between the wall and ceiling on
any chimney connector pipe unless wall protection is installed (consult pipe
manufacturer's instructions and local codes). If using wall protection, the wall protection
should be a U.L.-listed stove board with a one inch (25.4 mm) clearance (air space)
between the board and the wall. This should reduce the clearance to a combustible to 12
inches (304.8 mm) – again, be sure to check manufacturer's instructions and local codes.
