Tankless Water Heater Venting - You Have Several Options
First, with the tankless models, you have three options for venting; these include direct venting, non-direct venting, and outdoor models.
These three options are major decisions, because it determines where you place your tankless.
Using An Indoor Direct Vent
If you have a direct vent for indoor installation, you must have the proper area to place the unit so you can get the pipes installed correctly.

Venting Through The Roof
If you choose to vent through the roof, you must have the correct length of vent, which is the first mistake to avoid.
This length must include the turns and elbows.
You may have your unit installed just perfectly but you have the wrong length (not enough) of vent, so you cannot begin using the unit until you have it properly ventilated.
Outdoor Venting Options
If you decide to install the unit outdoors, make sure the unit you purchase is compatible with outdoor installation.

This could be a disaster in a colder area because these outdoor units receive combustible air from the outdoor air and expels it the same way.
