Problems with storing chim long term

[4Lmike]

Come the end of summer I may have to put the chim into storage for a couple of years. What problems can I expect to find when I come back to it? Is there anything I should before storing it away? It will be under a car port so out of the weather.

Thanks for all the advice - I didn't know so much preperation was needed!

What about one of these? http://www.airflow-uk.co.uk/search.php?mode=search... Anyone used on before?
