Gas Valve Current Draw…..

[Unregistered-Dodgeman]

Lg is correct, the anticipator is to be set to the amount of current that your gas valve draws. But this is a starting point depending on your partictular situation.
In general, the lower the number is set, the more often your furnace will cycle, but the temperature will have less variation in your house. The higher the number is set, the furnace will cycle less, but you will have wider temperature swings in the house.
Good Luck!
