The Richmond 5V40-7 functions through a standard atmospheric venting configuration, sending combustion exhaust out through a traditional B-vent vertical chimney stack.
If your home has (above 7 grains per gallon), you must install an expansion tank and consider a water softener. Sediment buildup will destroy the bottom of the tank within 3-4 years.
Check the top-mounted anode rod every 3 to 4 years. Replace it once the core wire becomes visible to preserve the tank lining. richmond 5v40-7 water heater specs
Employs a standard 1/2-inch gas control valve inlet (Robertshaw or Honeywell thermostatic gas valve assembly). Maintenance and Lifespan Expectations
The Richmond 5V40-7 has a "tall profile," meaning it is narrower and taller than a "short" water heater. This design is advantageous for homes where floor space is limited. A resource for the unit notes its "short profile allows this water heater to fit into spaces a taller model won't". The Richmond 5V40-7 functions through a standard atmospheric
It includes a factory-installed Temperature and Pressure (T&P) relief valve , which is a critical safety component designed to prevent the tank from exceeding its maximum working pressure, typically rated at 150 PSI . Performance and Maintenance The performance of the Richmond 5V40-7 is centered on efficiency and ease of repair.
The unit requires 5.0" – 10.5" W.C. gas pressure. A undersized gas line (e.g., 1/2" over 50+ feet) will cause poor performance. For runs over 20 feet from the gas meter, consider a 3/4" supply line. Check the top-mounted anode rod every 3 to 4 years
If you’re looking for specs for a unit you already own, this guide covers it. If you’re buying, consider a current model with a for energy savings — unless you need the exact replacement for a shared vent or existing install.
With an , this unit is not Energy Star certified (most 40-gallon gas units need EF ≥ 0.62 for certification). However, it meets federal minimum efficiency standards. For comparison, a condensing or power-vent unit might reach EF 0.70+, but costs significantly more.
The is a 40-gallon, natural gas, tall water heater with a 40,000 BTU burner . It’s a mid-efficiency, atmospheric vent model commonly sold at Menards (Richmond is a brand primarily for that retailer, made by Rheem).
