Steam boiler - summer maintenance?

ansky

I have a steam boiler and was wondering if any type of routine maintenance is required during the summer months.  Is it necessary to drain the rust out every week like I normally do in the winter?  Should I keep the boiler full or empty in terms of water level?

Thanks.

Keep the boiler full; drain the low water cutoff once a month instead of once a week.
