  • I want to purchase a Majestic 30" Ruby direct vent gas insert. My chimney is a bit higher than 35 feet. How can I configure the additional length beyond the 30 foot direct vent available? Thanks.

    You can use DuraVent's CL33 to get up to 35ft of vent.  If you need more you would need two couplers and an additional section of 3" flex vent.  Thanks for your question!
