All Field Vent Hoods are made of heavy
gauge aluminum and can be used with
natural gas, 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.
