This is something that will fluctuate from company to company. Traditionally with most companies if you were away for more than three or four days during the heating season you were supposed to have someone check on the house every day or two. Again, this can vary wildly from company to company.
And be careful about the being away on vacation versus the property being vacant. They are two very different things. Unoccupied does not equal vacant.
