DESCRIPTION

The Tjernlund Auto-Draft® vent systems are designed to side wall or vertically vent natural gas, LP-gas and oil-fired heating systems.
All models are supplied with the model PSA-1 Fan Proving Switch which will disable the burner(s) if a venting malfunction should
occur. The Auto-Draft® may be used on positive or negative pressure rated chimneys because the fan creates a negative pressure
throughout the entire venting system. The Auto-Draft® Venter must always be installed outdoors at the vent system termination.
Refer to heating appliance manufacturer’s instructions regarding specific venting requirements.

AUTO-DRAFT® VENTER FAN PERFORMANCE CURVES

Auto-Draft® Venter performance was independently tested by an accredited AMCA certified testing facility.
Selection of an Auto-Draft® Venter involves determination of the maximum volume of gas to be handled, the density of the gas and

the maximum static pressure which the fan must overcome.
Variable speed VSAD-Series Venters can operate at virtually any point to the left of the performance curve. For Side Wall applica-

tions add 0.50” W.C. to vent system resistance to accommodate the effects of wind loading.
Auto-Draft® Venter performance needs to be derated from 70

O

F performance curves to anticipated flue gas temperatures.

Please feel free to contact us for application and model selection assistance by calling 800-255-4208 or email us at
[e-mail]. Vent layout or other information can be faxed to 651-426-9547.
