Chris,

The current through the heater circuit, which is in series with the resistors (also in series), is about 150ma. You should be able to calculate wattage of each resistor using this current and the resistance value of each resistor. Power (Wattage) = Current squared x Resistance. I would typically at least double the calculated value and round up to a standard available size.

The following link may help. They state slightly different values for the same part #, than what Terry mentioned above, but they are close.
