I have got the relays prepared to be soldered in tomorrow, but I have a question regarding the TVS protection diode. Do I need to add the TVS diode for the smoke unit?

I will be adding a generic diode in series to the power wire, so the smoke unit runs at half wave AC. But also to prevent the heating element from burning up from just straight AC into the smoke unit
