SkyTech9800328 SKY-1001 TH Fireplace Remote Control and Thermostat

I need to replace an older skytech remote. Do I need to also replace the receiver?

had a receiver burn up and need replacing, know there are different types, need it to work with what was on it, receiver was a model UN3,

The description says it comes with remote transmitter and receiver. the picture only shows the remote. does it come with both?

Will this work with desa fireplace vygf33pra?
