Fire-induced seed release in protea ?

I have recently learned (?) that at least some species of Protea will
release their seeds only after being burned by a fire. The opening of
the seed capsules was described as an active process that occured about
an hour after the fire.
Could anybody please shed some light on the mechanism of this process,
if the above is true ? My guess for now is that some restraining part of the
fruit is destroyed by the fire, and structural strain (perhaps increased by
uptake of water vapour ?) is relieved by unfolding.
Thanks in advance,
