1. Inputs shown are believed to be
maximum capacities for inducers when
mounted on pipe sizes shown for
ordinary jobs where a moderate amount
of mechanical induced draft is required.
2. Consideration is given to typically
higher static pressure requirements for
larger installations, for the type of fuel
burned and for the type of draft control
installed.
3. Where pressure requirements are
unknown or believed to be unusually
severe, ask for complete performance
curves or consult factory.
4. All ratings have been developed in our
testing and research department and
have been approved by a nationally
known independent testing laboratory.
Certification is available upon request.
5. Heating capacities shown are for 1000
BTU per cubic foot natural gas and for
139,000 BTU per gallon No. 2 fuel oil.
Consult factory for capacities with other
fuels. Heating capacities are based on
typical combustion efficiencies and
allow for approximately 5 percent
ambient air drawn into inducer to
cool motor and drives.
6. Draft Inducers should be installed
in single wall vent pipe in order
to insure proper performance.
