1.7 CONDENSATION & DRAINAGE
Condensation is formed in the piping of a mitigation system when the air in the piping is chilled below its dew point.
This can occur at points where the system piping goes through unheated space such as an attic, garage or outside.
The system design must provide a means for water to drain back to a slab hole to remove the condensation. The
RN104 MUST be mounted vertically plumb and level, with the outlet pointing up for proper drainage through the fan.
Avoid mounting the fan in any orientation that will allow water to accumulate inside the fan housing. The RN104 are
NOT suitable for underground burial.
For RN104 piping, the following table provides the minimum recommended pipe diameter and pitch under several
system conditions.
*Typical RN104 operational ow rate is 25 - 90 CFM. (For more precision, determine ow rate by measuring Static Pressure, in
WC, and correlate pressure to ow in the performance chart in the addendum.)

@25 CFM @50 CFM @100 CFM
4” 1/8” 1/4” 3/8”
3” 1/4” 3/8” 1 1/2”
1.8 SYSTEM MONITOR & LABEL
A System Monitor, the manometer included in the RN104 System Kit or an audible alarm such as the (P/N 28001-
2, 28001-4 or 28421), is required to notify the occupants of a fan system malfunction. A System Label (provided
with RN104 System Kit sold by RadonAway) with instructions for contacting the installing contractor for service and
identifying the necessity for regular radon tests to be conducted by the building occupants must be conspicuously
placed in a location where the occupants frequent and can see the label.
1.8 ELECTRICAL WIRING
The RN104 operates on standard 120V, 60Hz AC. All wiring must be performed in accordance with National Fire
Protection (NFPA) National Electrical Code, Standard #70, current edition, for all commercial and industrial work,
and state and local building codes. All wiring must be performed by a qualied and licensed electrician. Outdoor
installations require the use of a UL Listed watertight conduit. Ensure that all exterior electrical boxes are outdoor
rated and properly sealed to prevent water penetration into the box. A means, such as a weep hole, is recommended
to drain the box.
1.9 SPEED CONTROLS
The RN104 Fan is rated for use with electronic speed controls; however, speed controls are generally not
recommended. If used, the recommended speed control is Pass & Seymour Solid State Speed Control (Cat. No.
94601-1).
