Perforate duct mounted near apex of attic.

High-End Product

The Company's Ridge Ventilator is a high-end ventilation product and is designed to compete
against continuous ridge vent systems and other high-end ventilation products.

Description of Ridge Ventilator

The SolarAttic Ridge Ventilator is designed for controlled ventilation of the attic. It can also be
used to collect attic heat and to redistribute this heat to another location. Unlike simple roof fans,
the ridge ventilator provides a “systems solution” to the problems encountered in attics. It does
this by using a patented custom duct technology that allows for the even collection of heat along its
length. SolarAttic owns 100% of this new technology represented by U.S. Patent 5,746,653.
Now, for the first time in history, proper ventilation of the attic is no longer guesswork. The ridge
ventilator eliminates the need for roof based passive vents (holes).

SAVC02 temperature & humidity control.

The electronic control senses the temperatures of 28º, 60º, 70º and 105ºF. When the attic peak
temperature drops to 28ºF the first time, a winter condition is sensed and the control activates its
humidity sensor. The attic is then vented whenever relative humidity exceeds a preset (adjustable)
%Rh (factory set to 35% Rh). Between 28º F and 60º F (spring), the attic is vented constantly. As
an alternative, the SAVC02 can also be set to the manual-on position and the ventilator would then
simply vent constantly regardless of temperature or humidity. This could be useful in prolonged
extreme subzero weather conditions. When the attic reaches 60ºF, the SAVC02 stops ventilation.
Ventilation, then, only occurs when the attic temperature exceeds the 105ºF setting. The SAVC02
control provides for fully automated year-around ventilation.

The RV 14-900ASolarAttic Ridge Ventilator comes with an in-line fan or centrifugal blower
unit (nominal 900 cfm @ free air) which is matched to a 50 foot length of custom perforated 14"
circular mylar non-insulated flex duct with end cap and gable mounting flange. The automatic
system operates on temperature and humidity settings for year around automatic ventilation of the
attic. Purchaser is responsible for proper installation and compliance with applicable codes.

First Installed In New Energy Home

The above photos are taken from the Company’s August 1997 Ridge Ventilator system
installation in the Energy Home I located in Elk River, Minnesota 55330. This energy home was a
joint project of Energy City (Elk River), Energy Alley (a project of the Minnesota Environmental
Initiative) and the Suburban Northwest Builders Association of Elk River, Minnesota.

A new solid state temperature and humidity
sensor comes with the SAVC02 and is placed at
the attic's peak. It simply plugs into the side of
the SAVC02. There are no complicated controls
to operate or settings to make. Simply plug the
control into a 115-vac source and plug the Ridge
Ventilator, Space heater or the combination unit
into the control. Everything is fully automatic!

n 115 vac @ 10 Amps Max current output
n Can be used with existing attic fans
n Temperature sensing -40º F to +150ºF
n Humidity sensing 0-50% Rh @ -40 to 185ºF

Other specs include the following: Winter vent condition is set at 28º F; Summer vent condition
is set at 105º F; Excess humidity vented @ 28º F and below when humidity exceeds 35% Rh;
Summer heat is vented above 105º F; Winter ventilation occurs from 28º F - 60º F if winter is set.

How To Install the RV 14-900A

Step

IMAGE Install_Manual-RV14-900A07.gif

a)

As shown in photograph on page 2, mount the blower motor at desired discharge point in
attic (near peak). Note:Blower motor assembly can be up to 10 feet away from discharge
point by using a non-perforated section of duct. This may be helpful in some hip roof
conditions.

b)

Extend duct out its entire length, and support at end with picture mounting wire through
eyebolt on end cap. Use nylon banding straps to support duct approximately every 4 feet.
Duct should not noticeably sag. Staple support straps to roof trusses or rafters.

c)

Mount controller to trusses or rafters. Mount controller close enough for blower motor cord
to reach controller, and for power cord to reach 110v attic outlet from controller.

d)

Mount sensor to attic truss or rafter near roof peak, in towards center of attic. Do not mount
sensor on an end-wall. Warning: Do not over tighten sensor-mounting screws!

e)

Plug sensor into controller side port.

f)

Plug power cord into 110v outlet and into controller. Make sure pushbutton switch on side
of controller is in the “out” position for automatic operation.

g)

Metal tape is supplied for making minor repairs to the duct if needed. It can also be used to
reattach the duct to the blower assembly or end cap if required.

h)

Miscellaneous supplies such as staples for nylon straps, and picture wire for the end-cap eye
bolt are not included.
