To strengthen flue pipe connections use short metal to metal self tappers, available in our Useful Items collection.
As with all vitreous pipe the bottom end narrows to a lesser diameter to enable insertion into other pieces of pipe (male is always on top). Key reason is that any condensation that trickles down inside pipe cannot escape. Straight lengths can be cut using a grinder and 115mm cutting disc (available from this online store).
Had to order additional bends after changing my mind about how to install the stove. Good quality bends which arrived next day. Service and support from Julian and his team at Stovefitters excellent.
I ordered 2x45degree elbows and a length of straight pipe. It was all excellent quality and fitted perfectly. Regrettably, the courier failed to deliver as arranged but an 'encouraging' call to them from Julian ensured the consignment was delivered 24 hrs later! that aside, this is a splendid firm to deal with, and I commend their products and services to you.
