Gas Press Switch for Tjernlund Fans
The Tjernlund 950-2080 is a gas pressure switch designed for use with Tjernlund fan systems. It serves as a safety component that monitors gas pressure levels during operation. This accessory is intended for installers or maintenance technicians working on compatible ventilation equipment. It ensures the fan operates only when correct gas pressure is present.
Installation fits VP-2F and Grainger 5C083
The switch is made to fit Tjernlund models including the VP-2F and matches Grainger item 5C083. Installation involves wiring into the fan’s gas valve circuit and mounting the switch body. A common issue is incorrect pressure calibration which can prevent the fan from starting. Verifying the pressure range against the appliance manual avoids this problem.
Limited to 2-1/2 In. connection size
This switch uses a 2-1/2 inch connection for gas line attachment. That dimension restricts its use to systems with matching pipe fittings. It cannot be adapted to smaller or larger connections without additional hardware not included here. The device functions solely as a pressure-activated safety control for gas-fired fan units.

Questions about this item
How do I confirm the gas pressure switch is operating correctly after installation?
The switch should activate the connected fan system when gas pressure reaches the calibrated set point; verify by observing the fan start and stop smoothly during a normal heating cycle.
What components are included with the 950-2080 switch and what must be purchased separately?
The package contains the gas pressure switch only; mounting hardware, tubing and wiring are not included and must be sourced separately.
Which version of this switch matches my Tjernlund VP-2F unit?
The 950-2080 model is specified for use with the VP-2F; confirm the 2-1/2 In. designation on your existing switch before ordering.
