I am in the process of replacing two MiniMax Heaters with MasterTemp 250s on an indoor pool and hot tub configuration. They have completely reconfigured the vent (as well as everything else) on these 250s. I would like to utilize the current venting which runs outside of the building. The current venting is Selkirk 4" double wall with Snap-Lock (the pipes just snap together). For example, one of the 3' straight runs of the existing vent has a part number 104036. I am trying to figure out what adapter I need from Pentair to go from the MasterTemps to this existing venting. In the manual it lists the following options:
I am assuming that I use the 77707-0086 because it is made by the same manufacturer, but looking at the manufacturer website I am not sure this will actually connect ot the existing venting.
Any help would be greatly appreciated.
