We just purchased a Jotul Oslo. It was delivered Friday and was supposed to be installed that day. Stove will be installed as a hearth mount in front of existing fireplace. The fireplace box is thick steel. The installers broke 2 blades trying to cut out the damper, top plate. They said they would have to come back with a welder to cut out the rest of the damper. I just got a message on my machine that it would cost 300 bucks for a welder, or 380 for an ovalized adapter. I feel like I have already paid them good money not only for the stove, but for the liner and the installation labor. Should I be liable for additional costs because they don't have the right tools for the job? Thus far the company has been very nice and I would like to stay on good terms with them, but not really sure how to approach this. I thought maybe offer to pay half of the cost of the welder and have them pay the other half? What should I do? ps I am a school teacher and don't really have any extra money for this.
