2.0 INSTALLATION
The RN104 can be mounted indoors or outdoors. (It
is suggested that EPA and radon mitigation standards
recommendations be followed in choosing the fan location.)
The RN104 Fan may be mounted directly on the system piping
or fastened to a supporting structure by means of an optional
mounting bracket.
The ducting from the fan to the outside of the building has a
strong effect on noise and fan energy use. Use the shortest,
straightest duct routing possible for best performance, and
avoid installing the fan with smaller ducts than recommended.
Insulation around the ducts can reduce energy loss and inhibit
mold growth. Fans installed with existing ducts may not
achieve their rated airow.
2.1 MOUNTING
Mount the RN104 vertically with outlet up. Insure the unit is plumb and level.
When mounting directly on the system piping assure that the fan does not
contact any building surface to avoid vibration noise.
2.2 MOUNTING BRACKET (optional)
The RN104 Fan may be optionally secured with a mounting bracket
manufactured by RadonAway (P/N 25007). Foam or rubber grommets may also
be used between the bracket and mounting surface for vibration isolation.
2.3 SYSTEM PIPING
Complete piping run, using exible couplings as a means of disconnect for
servicing the unit and for vibration isolation. As the fan is typically outside of
the building thermal boundary and is venting to the outside, installation of
insulation around the fan is not required.
2.4 ELECTRICAL CONNECTION
Connect wiring with wire nuts provided, observing proper connections (See
Section 1.8).
Note that the fan is not intended for connection to rigid metal conduit.
2.5 VENT MUFFLER (optional)
Install the mufer assembly in the selected location in the outlet ducting.
Solvent weld all connections.
The mufer is normally installed at the end of the vent pipe.
