Fitting wood burning stove and flue

[Sean]

Thanks for that Lawrence

As the clay flue has a 200mm diameter and the spiggot thats butting up against it is 140mm , I'll need to taper whatever "sealant" I use at this point so that the "tars" can run back down the chimney into the fire. Do you know if it is possible to build this ammont of silicone at this join? Also as I'll be sealing after the spiggot has been fitted (which means I only have access throught the 140mm hole in the spiggot) the "sealant" will have to be applied by hand (no roon for gun). Being only familiar with the normal silicone products, this would appear to be a messy job would it not?

I just applied plenty to the plate before bolting up. When it was in place, I put my hand up the hole and used a finger to smooth a fillet of silicone round the join. I wondered about condensed tars but have never had any problems. I assume that they flood the ledge and either come down the spigot or burn/evaporate in the flue! I burn mostly wood and make sure the temperature of the flue gets good and high before I turn the air down. I use one of those magnetic flue thermometers. I don't know how accurate/valid they are but it is quite fun monitoring the temperature. I know, I am a sad physicist!!

Is there something in the water today?
