DESCRIPTION
The Tjernlund Power Venter model HS-3C is designed to Side Wall or Vertically vent Natural and LP Gas appliances. The HS-3C is
supplied with a Fan Proving Switch which will disable the gas valve if a venting malfunction should occur.
SPECIFICATIONS
CAPACITY
The installer must verify that the Power Venter is sized
properly using the capacity table to the right. The
installer may reduce the vent pipe diameter to the size
shown in the selection table immediately after the draft
hood, draft diverter or barometric draft control. The
vent pipe length shown includes all equivalent vent pipe
before and after the Power Venter. To calculate the
equivalent vent pipe length, add the straight vent pipe
plus 10 feet for every 90 degree elbow and 5 feet for
every 45 degree elbow.
If venting multiple appliances with one Power Venter,
the total combined BTU/hr. input of all appliances must
be added together to size the Power Venter.
IMPORTANT: Elbows placed directly after discharge on Power Venter may cause erratic operation of Fan Prover. If elbows are
necessary on discharge, allow for a straight section of pipe 3 times the vent diameter being used before installing an elbow.
For example, if using 8” diameter pipe, allow for 24” of straight pipe before using an elbow.
