(2) Data given is least negative pressure required for pressure switch to remain closed.
Note: The typical sea level negative pressure data represents the minimum pressures expected. Shorter
length of flue pipe or single pipe systems compared to dual pipe systems should show higher (greater
negative) pressures.

Note:
All installations above 7,000 ft. require a pressure switch change. For installations in Canada the GMV95 & GCV9 furnaces are certified only to 4500 ft.
