The plate at the end of the tubes measures 5-1\/2 in. wide by 8-1\/2 in. tall, the assembly is roughly 13 in. side to side, and it runs about 15 in. from the end of the plate to the opposite end of the coil.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eA kit, not just a coil\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eReplacing a heat exchanger disturbs a lot of sealing surfaces, and this kit accounts for that. It includes eight coil o-rings, eight tube sheet seals, the tube sheet coil assembly, a sheet metal warning label, a metal tube replacement o-ring, a manifold bypass valve package, a tube of high temperature RTV silicone, a koala wool insulation service kit, a blower and adapter plate gasket, and an ignitor and gasket kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore you order\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eConfirm the model and build date on the heater data plate.
