Getting on a Flap

Just to top-off the previous chimney article, the damper flaps have been added.

Ta Da! Flaps Open...

...Flaps Closed

And the remote controls:

Flap Open...

...Flap Closed (or was it the other way round?)

Still more to do with adding the Chimney Surround to the cab roof and the boiler top covers.

Damping down a fire for a short period can be done either by restricting air flow into or out of the fire (or both). Whilst some air-in damping can be done by adjusting Sentinel 7109's ash pan, Sentinel chose to restrict the air-out mainly by enabling flaps to be placed over the chimneys.
