For what you show, these are vertical and no drip leg is required. ln the LF25 there is a table that shows max horizontal vent lengths. Those do apply even if the vent is vertical.

You must use that drain tee for the purpose of draining any condensate that forms in the vent and it must follow that specific vent material listed. We do have the different venting kits available as shown in the Product Spec book.

With an 80% are we producing enough condensate in the Colorado climate for this to be necessary? For the vent column can B-Vent be used or does it have to be stainless?
