I'm in the process of replacing my old gas fire and need to know what type
of flue I have. Removing the existing fire revals a large olde fashioned
open fire brick hearth, on the outside the chimney stack has been removed
and replaced with a aluminium cowl . Is this just a Conventional Chimney -
Class 1 Flue or a hybrid Class 2 Pre-fabricated Flue

AIUI that's a Class I with a Alloy cowl for a terminal - whcih may or
may not be suitable for gas applinaces.
