Vacuum Pump Application

• The vacuum pump vent length must be from 2 ft. to 25 ft.

• The maximum number of elbows in the vent system is two.

• Both isolation boots provided with the system must be installed prior to the vacuum pump (Figure 3.2).

Vacuum pump selection is based on the overall BTU/H input of each system. Refer to Chart 2.3 for

vacuum pump determination.

Example:

A system designed with one HLV-150 burner and two HLV-100 burners has an overall system input

of 350,000 BTU/h. This system requires the PB-9 vacuum pump as indicated in Chart 2.3.

NOTE: The average sound level of PB Series vacuum pumps is between 60 and 63 DBA. If the

application requires a lower decibel level, relocation of the vacuum pump or a sound-deadening enclosure

may be necessary. Contact factory.
