LPG injection

[Bruno!]

A couple of you have mentioned that when propane (lpg) is injected into
the manifold, the manifold soon freezes. What about circulating engine
coolant around the base of the manifold where the injectors are mounted? 
i.e. possibly by running another line from coolant system, in a similar
way a car's interior heater works, or having another water system which
runs across the exhaust, pumped by an electric pump, temperature regulated
by pump speed, fan, etc. The latter system i was thinking of using for a
hot water demisting system for when the going gets cold.
