VENT HOODS
All Field Vent Hoods are made of heavy .040 gauge
aluminum and can be used with LP gas or oil-fired equipment.
There are five diameters ranging from 3" to 8".
The concentric pipe, angled outlet deflectors, and spaced
plate design allow for better heat dissipation. This type of
construction minimizes the effects of heat on the outside wall.
The angled hood design reduces the effects of wind on the
venting system.
The inner and outer pipe are a continuous structure. This
allows for easy installation to power venter or vent pipe
and also eliminates possible positive pressure leaks in the
wall section.
Field Vent Hoods meet the highest standards for safety and
reliability, built in accordance with guidelines from NFPA211,
NFPA54, and ANSIZ21.47.
