(1) Data given is least negative pressure required f or pressure sw itch to close.
(2) Data given is least negative pressure required f or pressure sw itch to remain closed.
Note: The typical s ea level negative pressure data represents the minimum press ures expec ted. Shorter length of f lue pipe or single pipe systems
compared to dual pipe systems should show higher (greater negativ e) pressures.
