The \u003cstrong\u003eGV Series 3\u003c\/strong\u003e and \u003cstrong\u003eGV Series 4\u003c\/strong\u003e parts lists both show it as a \"Starter Tee Gasket,\" in the \u003cstrong\u003esection assembly\u003c\/strong\u003e figures (Figs. 11\/12) and again in the later assembly figures (Figs. 18\/19), marked for all boilers on the list. It is a flat \u003cstrong\u003ered gasket\u003c\/strong\u003e with \u003cstrong\u003efour mounting holes\u003c\/strong\u003e and a \u003cstrong\u003elarge round center opening\u003c\/strong\u003e, shown in the photo against a ruler so you can check the size against the \u003cstrong\u003egasket\u003c\/strong\u003e you are replacing.\u003c\/p\u003e\n\n\u003cp\u003eOn a \u003cstrong\u003econdensing boiler\u003c\/strong\u003e the vent connection is not just a pipe joint. The \u003cstrong\u003estarter tee\u003c\/strong\u003e is where the \u003cstrong\u003eflue gas\u003c\/strong\u003e leaves the boiler, so the \u003cstrong\u003egasket\u003c\/strong\u003e has to hold a gas-tight seal against the boiler while it sees heat and condensate. A hardened, cracked or shifted \u003cstrong\u003egasket\u003c\/strong\u003e can leak \u003cstrong\u003eflue gas\u003c\/strong\u003e into the boiler room, drip condensate onto the jacket, or draw room air into the vent. The \u003cstrong\u003eWeil-McLain\u003c\/strong\u003e parts list notes that the \u003cstrong\u003e699-999-025\u003c\/strong\u003e GV \u003cstrong\u003estarter tee\u003c\/strong\u003e itself comes from the \u003cstrong\u003event manufacturer\u003c\/strong\u003e, so the \u003cstrong\u003egasket\u003c\/strong\u003e is the one part you order here when you are resealing that joint.\u003c\/p\u003e\n\n\u003cp\u003eReplace the \u003cstrong\u003egasket\u003c\/strong\u003e every time the \u003cstrong\u003estarter tee\u003c\/strong\u003e is removed. Clean both \u003cstrong\u003emating surfaces\u003c\/strong\u003e, line the four holes up with the fasteners, and tighten evenly in a \u003cstrong\u003ecross pattern\u003c\/strong\u003e so the \u003cstrong\u003egasket\u003c\/strong\u003e seats without crushing. After the boiler is running, check the joint with a \u003cstrong\u003ecombustion analyzer\u003c\/strong\u003e for \u003cstrong\u003ecarbon monoxide\u003c\/strong\u003e and look for any sign of \u003cstrong\u003eleakage\u003c\/strong\u003e. The companion \u003cstrong\u003einspection port gasket\u003c\/strong\u003e is the \u003cstrong\u003e590-317-628\u003c\/strong\u003e, and the \u003cstrong\u003e560-907-629\u003c\/strong\u003e is the \u003cstrong\u003einspection port cover\u003c\/strong\u003e. Inspect the joint at every annual service for staining, soot or crust, which are usually the first signs of a failing seal.
