On a commercial property policy, there is no coverage for water damage caused by a frozen pipe bursting unless heat is maintained in a building. What is the proper level of heat that must be maintained?

We have not seen a specific temperature given for the proper level of heat. The CP 10 30, Causes of Loss—Special Form, states only that the insured must do his best to maintain heat in the building. The form does not provide a temperature, but it can be assumed that this would require having a power source and a properly working furnace or other heat-providing apparatus in the building.
