Installing the Conair GasTrac
(continued)
Proper Exhaust Recommendations
Conair recommends that the customer contact a local contractor that can determine
the proper line size based on specific conditions.
The following information may be required for the contractor to make a proper
exhaust selection:
1
The addition of exhaust ducting to the GasTrac combustion flue stack must not
decrease the CFM {CMH} by more than 10%.
2
The use of a booster blower (if applied) at the end of a duct run should not
increase the combustion exhaust air flow by more than 10%.
3
In order to ensure that Steps 1 and 2 above are not exceeded, the CFM {CMH}
of the combustion exhaust should be checked prior to the addition of the
exhaust stack. After adding the exhaust stack, the CFM {CMH} should be
rechecked to ensure that the air flow is within the guidelines. The GasTrac
should not be ran for long periods of time without being properly connected to
the exhaust ducting, directing flue products to a suitable point exiting the
building.
The following chart is supplied to assist the contractor for specific parameters of
each GasTrac model.
Refer to the GasTrac’s operation manual for additional
information.
