This is for vertical installation of the Eccotemp 45HI (indoor models). You will need to purchase additional Z-Vent straight pipe. You will need to determine how many additional feet you will need as well determine if you will need a condensation drain. Also remember there is a maximum vent run of 20 feet, subtracting 4 feet for every 90 degree elbow in the run. Please also note that any vertical venting installation with more than a 5′ run length requires a vertical condensation drain pipe as well.
