Customer service was excellent, boiler is very efficient and I love the way I can set the boiler to different btu parameters. Installation instructions are vague in regards to initial setup. If the zones are small, it knocks the boiler out on high temp.

Coaxial vent piping became a problem when we needed to offset based on customer expectations. We needed 3- 90’s, and supplier only stocked 2. Then, the piping we receiving had some dents and dings. The inner support has broken in shipping, and the ends were crushed a little. We were able to straighten out with channel locks, but this should not be required.
