: First check the pilot light assembly. If the pilot flame refuses to stay lit after manual ignition, the thermocouple is likely worn out or misaligned and requires replacement.
The Richmond 5V40-7 is an excellent choice for where existing metal venting is already in place and for homeowners who prioritize low upfront costs over maximum energy efficiency.
Knowing the physical dimensions of the Richmond 5V40-7 is crucial for determining if it is a suitable fit for your home. While exact measurements for this specific model are not available, standard dimensions for similar 40-gallon natural gas units offer a reliable guide.
If you experience a sudden drop in water temperature or a loss of hot water flow, use the standard Richmond Troubleshooting Manual framework to diagnose the system: Use and Care Manual - Richmond Water Heaters
The Richmond 5V40-7 is a 40-gallon, gas-fired water heater designed for residential use. It's a reliable and efficient option for providing hot water to homes of various sizes. richmond 5v40-7 water heater specs
The Richmond 5V40-7 is a 40-gallon, standard atmospheric vent natural gas water heater designed primarily for residential use. Manufactured by Richmond (a subsidiary of Rheem), this model is engineered for reliability, standard efficiency, and straightforward installation in homes with existing vertical chimney or roof venting systems.
36.4 to 40.4 Gallons per hour at a 90-degree rise
The Richmond 5V40-7 is built on a standard atmospheric vent platform. Here are the "nuts and bolts" numbers: 40 Gallons Fuel Type: Natural Gas
The 5V40-7 is susceptible to common issues: : First check the pilot light assembly
Premium-grade for extended tank protection against corrosion. Ignition: Easy-to-light system (does not require matches).
Because this is an model, it relies on a vertical chimney or vent pipe to pull exhaust out of the home via natural convection. It does not require a power outlet for a blower fan, which is a major plus if you want hot water during a power outage.
For practical use, the of 67 gallons is more important. FHR measures how much hot water the tank can deliver in the first hour of use—accounting for stored hot water plus recovery during that hour. At 67 gallons, this unit can handle:
The unit features a tough, thick-gauge steel tank layered internally with a . This glass-like coating prevents water from making direct contact with the steel, neutralizing rust and scale build-up. Coupled with a premium magnesium anode rod, the tank actively fights galvanic corrosion to ensure a long operational lifespan. 2.
