Connecting Stove Pipe to the Stove
You will note that there are two holes in the spigot end of the pipe. Please note that these holes are used during the manufacturing process and are not in any way used for installation purposes.

Vitreous stove pipe should be fitted with the socket uppermost, small end downward. Ideally the spigot end should sit inside the spigot outlet from the stove. Thus, no condensate can escape to spoil the appearance of the finished installation, and any tar deposits remain inside the stove pipe at all times and drop back inside the stove. Some stove manufacturers have odd diameter spigot outlets from their stoves (we don't understand why !), and there is a 75mm PE (plain end) length available to assist in the installation if this is the case.

Fixings
You can seal the joint between the stove and the stove pipe with either fire cement or ceramix. If the fit is quite loose, it's also possible to pack the joint with fire rope prior to using fire cement or ceramix.
