Inground pool

Imtrying to do an install by myself. I've got the pool ready for tile and then im ready for water. However, I've yet to install the heater or pumps (one for the jacuzzi). My pool is in my basement and i have a natural gas heater and according to the installation procedures i MUST pipe it above the roof line. I understand that i may also be able to pipe it outward , underground till the pipe would be ten feet from structure and then come out of ground three feet. going up is proving difficult as the pool is beneath the garage with living quarters above that. I need a lil more info regarding the flu placement. Maybe someone else has similar experience. Thanks for any feedback. -Andrew
