2014 Pent Air Master Temp 200 Propane Pool or Spa Heater

This 2014 Pent Air Master Temp 200 Propane heater was used for a custom hot tub that was shut down in 2015. Heater was removed and has been stored in garage since. Very minimal service hours and in excellent (like new) condition. Asking $400, but will entertain offers as we have no use and want it out of the garage.
