FAQ

1. Do I need to get on the roof to install Turbine Boss?
Ye s.
2. Isittruethatsmallairgapsaroundlightxtures,A/Cregisters, 
and ducts cause warmth to escape from my home in winter?
Yes. In older homes as strong winter wind blows across the roof,
turbine attic ventilators suck warm ‘conditioned’ air from the rooms
through a multitude of tiny air gaps that lead into the attic. Remember,
each turbine vent straddles a 12-inch hole cut into your roof creating a
‘low pressure’ zone that sucks warmth from the home.
3. Is the plastic construction of Turbine Boss really durable?
This polymer resin has a sun-guard component (UV Inhibitor) that
provides extra measure of long term strength, stability and heat
resistance. Today, half of all roof vents are molded plastic construction.

better.
The Thermostatic Controller (concealed) is a special metal spring-like
device that reacts to temperature changes. It expands in heat and con
tract in cold. This drive mechanism is linked to the louvers, causing
them to OPEN and CLOSE. It needs no batteries or electrical hook
up. It’s maintenance-free. Just install it and forget it.
5. Howdoesthisdampertbothsizesofresidentialturbinevent: 
12 and 14-inch diameter?
Ninety-Five per cent of all turbine attic ventilators on homes are
12-inch diameter. Only 5% are 14-inch diameter. We designed Turbine
 Bosstotthepopular12-inchdiameter,andstilladapttothe14-inch
diameter by using the enclosed “L-Bracket” adapters. The enclosed
instructions show how to easily insert them into the damper.
6. Iseea“WinterAir-FlowSelector”feature.Pleaseexplainit.
This feature allows the damper louvers to close 80% during cold
temperature while remaining slightly open (20%) to exhaust the attic
moisture. Once you are on the roof, you easily determine if turbine
vents are 12-inch or 14-inch diameter. For 12-inch turbine choose
setting #3…for 14-inch turbine setting #1. See instructions.

15-minutes. You will need a screwdriver. Wear rubber sole shoes on
the roof.

9. Afterinstalling,howwillIknowifTurbineBoss™isworking?
You can do this. Go into the attic and look up through the turbine vent
opening in the roof. During winter you will see that Turbine Boss

You will know it is working.
