thanks sevver..the small amount of pipes i have , filter and pump are all to the right of the heater with wide open space in front. only pipe on left side is the natural gas. it's not a setup that requires threading through pipes or leaning over them to get the job done. electrical is all to the side and waist to face level high so completely out of the way. my pool shed is big and tall so i think things will be ok..good answer and i didn't think there would be any issue if the gadgets weren't running..thanks again.
