Manual for Dearborn gas heater model DRC 40 A N

There is a pilot, burner orfice spuds, and a gas valve pressure regulator spring that comes in a conversion kit that you will need. It will come with instructions. Google the manufacturer for a dealer near you. Hope this helps.

Whirlpool is AO Smith tank-type heater.
Year, model, type of heater not known.
So add a comment and then expert can look up the manual.

You probably have power vent, or dampered water heater, otherwise the only wiring would be for thermopile, thermal reset, and igniter.
Power vent, or dampered, of flow control water heaters plug into outlet, and wires from gas control run to the various components.

Type of gas control valve is not known.
Brand of water heater is not known.
FV event can mean that air intake is clogged, gas control valve has gone bad, or FV system has tripped, or TCO has tripped ... or all of above.
Clean air intake, download manual from manufacturer and read troubleshoot section, call manufacturer.

40 gallon electric heater at Lowes costs 207, and is easy do-it-yourself using same basic information shown in link above for installing gas heater, except less work.

To have gas water heater installed, can run $2-300 for installation plus cost of heater.
40 gallon natural gas water heater at Lowes starts at $300+, and tanks with longer warranty cost more and last longer.
Trailers require specific type of gas water heater, so be sure to request correct model.

If you maintain the tank: keep chemicals out of same room as gas water heater, attach bare copper ground wire between hot and cold pipes, flush tank each 6 months, clean gas burner each year as shown in manual, read the manual entirely for specific information about your model, and inspect/replace anode rod every 2-3 years then basic 6-year tank can last much longer.

Gas water heaters have not changed much over the last few decades. The manual that they sent you should suffice. What sort of a problem are you having?
