      Ordered the 120K unit. The company rep called me and reviewed my needs. Changed to 100K unit. Purchased the LP gas conversion unit. I wanted to install it myself. I read through all the instructions several times, and had a licensed installer review everything I did. I not sure if he was surprised how good the instructions were, or if he was shocked by how closely I followed them, but everything went great. Changing from natural gas to LP was not a problem. I even bought a manometer to keep an eye on the LP gas pressure since I've never used LP before. The furnace worked the first time it was turned on. I purchased it in Oct, but family health issues delayed the installation. It went into service on 12/21/12 it has kept us nice and warm. It had a cosmetic dent from shipping, but I just straightened it out.

      Pros Easy to Use, Easy to Install, Easy to Work With, Great Value
