INSULATED
FLEX PIPE
CENTRAL FORCED AIR KIT
The knock-outs provided on the sides of the
ME43 fireplace allow the connection of insulated
flexible pipe which enables you to heat adjacent
rooms up to 50 feet from the fireplace.
The ducting system must be installed as de-
scribed below :
1. Fix the adaptor at the side of the fireplace by
twist-locking the adaptor to the fireplace.
You can use more than one outlet on the
fireplace (Figure 11).
2. Attach the 5" flexible pipe, using the col
-
lars provided. Important: Make sure that
the plastic wrapping around the flexible
pipe will not be in contact with the fire-
place.
3. Route the flexible pipe to the chosen loca
-
tion. The ducting system can be installed
either in an upper room or in a lower
room.
4. Attach the flexible pipe to the fan, using
the collars (Figure 12).
5. Fix the decorative grill fan adaptor to the
fan.
6. Attach a standard 3" x 10" grill to the
adaptor.
7. Install the blower thermostat
in that part
of the house to be heated by the hot air
duct. Do not install the blower thermostat
in the room where the fireplace is located.
A cooling thermostat can be installed in the
same room as the unit. This thermostat
will turn on the blower when the room
where the fireplace is located becomes
too hot.
This option requires electricity. Make sure that
the connections to the fan have been made
according to the local codes and comply with
their requirements. It is possible to connect
a flexible pipe to a central heating system.
Make sure the pipe will be connected to the
warm air supply duct, not to the return air
duct (Figure 13). Contact your local furnace
installer for installation guidelines.
Chase Enclosure
A chase is a vertical box-like structure construct-
ed to surround the fireplace and chimney. Refer
to Figure 14 for a typical chase configuration.
As with all chimney installations, avoid overhead
obstructions such as trees, power lines, etc.
A chase should be constructed and insulated
just like any outside wall. In a cold climate, we
recommend the base of the chase should also
be insulated between the solid continuous floor
beneath the fireplace and the chase bottom.
Chase insulation in a cold climate installation
is not required for safety.
