As a veteran-grade replacement part, it serves as a critical safety component for \u003cstrong\u003eTjernlund VP-2\u003c\/strong\u003e, \u003cstrong\u003eVP-3\u003c\/strong\u003e, \u003cstrong\u003eWHK-2\u003c\/strong\u003e, and \u003cstrong\u003eWHKE\u003c\/strong\u003e models. This normally open (NO) switch is designed to monitor gas pressure at the burner, ensuring the power venter is energized before gas flows to prevent hazardous accumulation. This \"New Style\" model replaces older, discontinued versions and features a streamlined design that utilizes a single 1\/4-inch aluminum tubing connection, eliminating the need for an atmospheric vent. Rated for 120 Volts with a 2 Amp capacity, this 2-1\/2 inch \u003cstrong\u003eTjernlund pressure switch\u003c\/strong\u003e is compatible with both \u003cstrong\u003enatural gas and propane (LP)\u003c\/strong\u003e applications. For professional installation, ensure the diaphragm is mounted in a vertical position to maintain accuracy and prevent moisture-related nuisance tripping in high-efficiency venting systems.\u003c\/p\u003e\n\n\u003cstrong\u003eKey Benefits for Technicians\u003c\/strong\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBroad Compatibility:\u003c\/strong\u003e Direct replacement for \u003cstrong\u003e899-0415\u003c\/strong\u003e and \u003cstrong\u003eGFP6128\u003c\/strong\u003e, fitting \u003cstrong\u003eVP-2F\u003c\/strong\u003e and \u003cstrong\u003eVP-3F\u003c\/strong\u003e millivolt packages.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSimplified Installation:\u003c\/strong\u003e \"New Style\" design requires only one pressure tap connection, reducing potential leak points in the \u003cstrong\u003egas-fired furnace\u003c\/strong\u003e or water heater circuit.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSafety-First Operation:\u003c\/strong\u003e Prevents system operation if upstream gas pressure is insufficient, protecting \u003cstrong\u003eHVAC ventilation systems\u003c\/strong\u003e from unsafe conditions.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVersatile Application:\u003c\/strong\u003e Validated for use across the \u003cstrong\u003eWHKE Millivolt Interlock Kit\u003c\/strong\u003e and various \u003cstrong\u003epower venter systems\u003c\/strong\u003e.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cstrong\u003eCommon Questions \u0026amp; Technical Insights\u003c\/strong\u003e\n\u003cp\u003e\u003cstrong\u003eIs this switch compatible with older Tjernlund venters?\u003c\/strong\u003e\u003cbr\u003e\nYes, the \u003cstrong\u003e950-2080\u003c\/strong\u003e is designed to replace discontinued \"Old Style\" switches. While the internal diaphragm and electrical specs match, the \"New Style\" does not require an atmospheric vent connection.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes this kit include the necessary mounting hardware?\u003c\/strong\u003e\u003cbr\u003e\nThis \u003cstrong\u003eTjernlund replacement kit\u003c\/strong\u003e typically includes the gas pressure switch, 1\/8-NPT pipe plug, black pipe tee, and self-tapping screws. The 1\/4-inch aluminum tubing is generally sold separately or reused from the original installation.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan this be mounted in any orientation?\u003c\/strong\u003e\u003cbr\u003e\nNo. To ensure optimal technical performance and long-term reliability, the switch must be mounted so the diaphragm is in a vertical position per factory specifications.\u003c\/p\u003e\n\n\u003cp\u003eDisclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
