    We've had a gas back boiler removed from our 30s semi, leaving a metal flue liner dangling, with fibreglass insulation sealing around it. At the top is a gas terminal.

    Does the metal liner need removing before sealing off the bottom (+ adding an air vent)?

    Is the gas terminal sufficient to cap or should it be removed and capped?
