Damper points that decide the fit in Fullers
Practical notes from the damper installers serving Fullers.
Made for wood-burning fireplaces
Top-sealing dampers are designed around the rhythm of a wood fire. The flue is opened before the fire, left open until the ashes are cool, then closed on its gasket until the next fire.
That makes them a good match for a masonry fireplace that burns wood a handful of times a year or more. We confirm your fireplace is used that way and that nothing else vents into the same flue before recommending one. If another appliance shares the flue, the damper is not the right answer, and we explain what is.
Trimming the cable and tidying the chain
Top dampers come with more cable than most chimneys need so they suit tall flues. Once the tension is set, the extra is trimmed, as the Lock-Top instructions describe.
We leave the chain and handle hanging neatly at the bracket, clear of the opening and the fire area. A tidy handle is easier to use and less likely to be caught by a screen, a door or a poker. The trimmed end is finished so it will not fray or snag a hand.
Spring open, cable closed
Spring tension lifts the lid of a top damper when the cable is released. Pulling the handle down and locking it at the bracket holds the lid shut against its gasket.
That design means the natural resting state is open. We show you how to release the handle to open the flue and how to lock it closed afterward, and we explain what to check if the lid ever stops lifting fully. That is also why the handle position is the quickest way to tell whether the flue is open.
Closing the flue while the house is empty
If the home sits empty for weeks, an open flue is an easy way in for birds and insects and an easy way for rain to reach the firebox.
With the lid locked closed, the flue stays shut while you are away. We show you how to confirm the lid is locked closed before you leave and how to check it is open when you return and light a fire. Before the first fire after a long absence, a quick look up the flue confirms nothing has moved in.
