Field Controls Oil Venting Systems - Manual (Page 4)

Power Venting
In the early 1980's, Field Controls introduced the PVO
power venter. It was an indoor mounted power venter
connected to the outside wall via a vent hood. The PVE,
PVO and PVG series venters are still popular and in use
today. In 1988, Field introduced and patented the outdoor
mounted SWG power venter. It combined the motor,
blower, and vent hood in one convenient package.
The double wall pipe allows for near-zero clearance to
combustibles. The SWG is available aluminized for gas
applications and stainless steel for oil use. In 2007,
Field introduced the ComboVent™ Power Venter.
The ComboVent is all stainless and includes a
combustion air connection and an extendable body for
walls up to 14 inches thick.
Direct Venting
In response to the growing use of direct vent burners, Field
Controls developed the Field Direct™ Venting System in
2005. The FDVS is included as part of the original
equipment on many popular brands of furnaces and
boilers and is not yet available through wholesale
distributors. The FDVS includes a double wall system that
simultaneously vents combustion gases while bringing
combustion air to the burner.

The fan is a part of the furnace and forces
combustion gases out the sidewall via double-walled
sealed pipe. Combustion air is pulled into the
structure simultaneously.
