Installing the Conair GasTrac
Gas Line Sizing
Conair recommends that the customer contact a local contractor that can determine
the gas line size based on specific conditions.
The information below will be required for the contractor or gas supplier to make
the proper gas line selection:
1
The required inlet gas pressure to the GasTrac’s regulator must be less than 5
psig. Also, the incoming gas pressure should not vary more than 5" H
2
O
between no gas flow and maximum gas flow. The regulator on the GasTrac can
be used to adjust the supplied gas pressure to 7" H
2
O.
2
If an additional regulator is required to obtain the proper delivery gas pressure
(1 to 5 psig), the regulator must have an
ANSI Class 6 positive shut off to pre-
vent gas pressure increase when the GasTrac is turned off.
The following chart is a listing of the maximum gas usage and inlet line size used
on each GasTrac.
GasTrac Model Max Gas Flow (CFH) {CMH} Inlet Line Size (NPT)
CGT150 150 {4.2} 3/4 in.
CGT250 250 {7.1} 3/4 in.
CGT350 350 {9.9} 3/4 in.
CGT500 500 {14.1} 3/4 in.
CGT700 700 {19.8} 1 in.

NOTE: Conair strongly recommends that a “drop tube” be utilized when piping the gas
line into the GasTrac. This will help to prevent any oil or metal shavings, created dur-
ing the installation process, from entering the GasTrac. If this action is not completed,
warranty on components in gas line will be voided.
