Burn damage stacking clarification

Quick question;

Does Burn damage from Righteous Fire + Scorching Ray + Flame Wall stack?

I think it does, but I need to make sure I'm not gimped by using FW and not Firestorm.

I've used the search function and google, but Flame Wall usually isn't talked about regarding burn stacking.

Thank you in advance.

Unless otherwise stated, DoTs from different sources stack.

So Flame Wall dot damage should stack with scorching ray and righteous fire.
