My dad had a regency I2400 wood insert installed around 3 years ago in his basement rec room and the stove works great but he seems unhappy with the liner install.The original installers put in a partial liner due to the way the chimney flue is designed.The Chimney has 2 flues!The first floor one is straight up from the fireplace but the one in the basement angles to the right a quarter of the way up making it very hard to put in a full liner.Hes had it cleaned this way and now wants to see if a full liner can be installed so the stove doesn't need to be pulled out for a cleaning.He had one chimney place come out to take a look and they said it could be done but pricey because a hole would have to be made outside where the angle is in order to guide the liner around the bend up to the top.The cost of the brick work over a grand! I don't no the total cost though.Is there any big disadvantages of leaving things alone and forgetting about the full install.I guess that dad seeing that I and my brother both have full liner installs wants one too.
