Pentair 474059 Tube Sheet Coil Assembly Kit For Model 250NA; 250LP MasterTemp(R) Heater
The Tube Sheet Coil Assembly has 4 tubes and the kit includes 1 tube of high temperature RTV silicone, the O-ring kit, ignitor, insulation kit and blower adapter plate and gasket kit. This assembly is for heaters made after January of 2009.
Fit perfectly. Comes with most things needed to do the job. It’s missing the manifold gasket as well as blower motor gasket ( got one but it was not the right size). Customer service representative was informative and most of all was a live person and not an email request.
