Product details
Raypak 009840 is the genuine 8 in. indoor stack top kit for the R336A and R337A digital pool heaters.
What it is
The stack top sits on top of the heater and finishes the flue. Raypak builds separate tops for indoor and outdoor installations, and sizes them by model, which is why the same heater family has 6 in., 7 in. and 8 in. versions. This is the indoor 8 in. version for the R336A and R337A.
Before you order
Check two things: that your heater is one of the listed models, and that your installation is indoor. An outdoor heater needs the outdoor top instead, and a smaller model takes a smaller diameter. Getting either wrong means the part will not sit correctly on the heater.
