The Conair GasTrac is classified under the National Fuel Gas Code [ANSI Z233.1]
as a Category III gas appliance. An exhaust flue is required to vent the combustion
gases produced by this appliance. The purchaser is responsible for installing an
exhaust flue that meets all local, regional and national codes in the installation area.
For you safety, Conair recommends that you consult a licensed mechanical contrac-
tor who is familiar with gas flue and ducting codes in your area.

Installation recommendations
❒
Provide each GasTrac with a dedicated, vertical stack that exits the
building vertically through a rain-protected roof penetration. Limit any
horizontal ducting runs to 4 feet.
❒
Use a stainless steel, fabricated chimney flue.
❒
Vent size should be 6 inches in diameter. If you connect multiple
GasTrac units to a stack manifold, adjust the stack size accordingly.
❒
Static pressure at the flue collar must not exceed 1 to 2 inches water
column.
❒
Install an induced draft fan between the GasTrac exhaust outlet and
stack ducting, if you have more than 1 to 2 inches water column pres-
sure at the flue collar while the GasTrac is operating.
