: : I recently bought a 400,000 BTU Pool heater. I'm planning to run a 1" black pipe from the meter to crawl space then to the outside again(doing a shorcut). Do I need to bury lenght of the pipe in crawl space? What is the minimum depth should I bury the pipe thats outside the house. Is one inch pipe sufficient enough. Heater requires 1000 btu/hr WC 7"min
: : maximum 14 WC.
: : Any tips will be appreciated.
