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 applications 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 70OF 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.
