Title: Installing an inset boiler into a fireplace
Post by: chilled on October 17, 2012, 08:49:46 AM
Prior to receiving delivery of my new inset multi fuel stove I've been reading an on-line version of the manual.
I've been mentally running through the work required and a couple of questions (so far) have hit me.

I was surprised to see that the boiler is fully sealed into the fireplace surround and a continuous flue is not required, the stove vents into the fireplace area and onwards up the chimney. My Chimney is lined but I was expecting to have to link the stove with the flue rather than have an 'open space' between the two.
This makes installation a lot easier but I was surprised to see this, is this the norm?

Connecting the copper pipe, I'm guessing the only way to do this is to connect a section of pipe to the back boiler prior to sliding the stove into place.
Concerns about water tightness immediately comes to mind.
I'll also need to bury the pipe in to the wall, and was wondering if thermal flexing would be an issue causing cracks to appear in the long term. My alternative would be to run it outside and lag it, but not too keen on that option.
Another option could be to run the pipe down under the floorboards,over to a cupboard and follow the rest of the ch pipes, but thermal siphon capability would be zero so I assume that would be a no-no.

Anyone have any experience that they would like to share?
