The Raypak Outdoor Stack Kit does it job, our pool heater is now working much better without rollout switch kicking off. I cannot say enough about the service from Sunplay, everything was so easy to order and they shipped and the delivery was quicker than expected.
One comment on the stack, the original design seems to be flawed as my old Raypak heater never had this issue from the wind! Not sure what has happened with the new design that I now need a stack. I wrote this review per Sunplay's excellent service vs. the overall Raypak unit and subsequent technology.
