| POWER VENTERS APPLICATIONS
Power venters are required on gas or oil indirect tired
heaters where:
1 Negative pressure exists inside the building
Flue pipes have downward or long horizontal
runs.
3. Flue sizes are reduced to save space and costs.
4. Heaters are vented directly through a side wall with no
vertical stack.
5. Heat exchangers or stacks are extremely cold and and
will not provide adequate draft on start up.
