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.

This installation manual does not contain any system design documentation. Installation and use of Tjernlund controls like the CPC-2
Constant Pressure Controller, EXP-4 Appliance Interlock Expansion boards or MAC-4 Multiple Appliance Controller are not covered by
this manual. Please refer to those accessory installation manuals.
