How To Wire A 12V DC Tankless Water Heater In An RV That Previously Had A 120V Water Heater

Question:

I currently have a gas electric hot water heater. The electric is 120 volt. The tankless units are gas and 12V DC. Will I need to find or run a 12V DC source from somewhere or should there already be a 12V DC source at the present unit.?

For your new tankless water heat that runs on 12V DC, such as Furrion RV Tankless Water Heater - Gas - Automatic Pilot - 60,000 BTU - 16" x 16" Door # FR98SR, you will need to wire this to your RV 12V DC battery and it's not likely there's already any 12 volt wring near your current heater and a 12 volt heater cannot run using 120VAC

I have attached a detailed installation video showing this process.
