OPTIONAL DIRECT EXHAUST SYSTEM
The optional FDVS is to be used in conjunction
with the PF boiler for indoor installations requiring
through the wall venting. The FDVS is designed
as an integral part of the PF boiler, eliminating the
need for a power venter.
Oil boiler FDVS kits include an oil burner with
adjustable post purge timer and solenoid valve.
For through the wall venting, this post purge burner
must be used in place of the standard burner that is
furnished with the boiler.
SELECTION OF BOILER SIZE
Selection of boiler size should be based upon “Net
I=B+R Rating MBH being equal to or greater than
the calculated heat loss of the building.
These boilers are low pressure sectional cast
iron boilers constructed and hydrostatically tested
for a maximum working pressure of 50 psi in
accordance with A.S.M.E. (American Society of
Mechanical Engineers) Section IV Standards for
cast iron heating boilers. They are capacity rated
in accordance with the code of the Hydronics
Institute.
These boilers operate on #2 Heating Oil, Natural
Gas, or Propane Gas, with the proper burner.
