The 6G40-36F1 features a Flammable Vapor Sensor (FVS). This safety device continuously monitors for the presence of gasoline or other flammable vapors. If detected, the electronic control will automatically shut down the heater to prevent ignition. How to Light the Pilot richmond water heater model 6g40-36f1 manual
Most modern Richmond Essential gas heaters use a Piezo igniter, eliminating the need for matches.
Turn the gas control knob to the OFF position and wait 5–10 minutes for any gas to dissipate. Turn the knob to PILOT.
Press and hold the knob down while repeatedly pressing the Piezo igniter button until the status light blinks or you see a flame through the sight glass.
Continue holding the knob for 30–60 seconds after the pilot lights, then release it and turn it to ON. No hot water? How to relight a water heater (newer style)

Alternatively, because Richmond and Rheem share many components, the Rheem website (www.rheem.com) may list a cross-reference manual under a similar model like XG40T06EC36U1.
Q: Is the Richmond 6G40-36F1 compatible with a smart thermostat? A: No. The manual explicitly states this model uses a standard gas valve with a built-in thermostatic dial. It is not compatible with external smart controls.
Q: How long should this water heater last? A: The manual cites a 6-year limited warranty on the tank and 1 year on parts. With annual maintenance (flushing and anode inspection), real-world lifespan is 10-12 years.
Q: Can I install this model in a mobile home? A: Check page 4 of your manual. The 6G40-36F1 is generally not rated for mobile home installation unless specifically labeled “MH.” Standard models lack the required restraint bracket.
Q: I lost the manual. Can I use a Richmond 6G40-38F1 manual instead? A: Mostly yes. The “38” vs “36” indicates BTU difference. While the mechanicals are similar, the venting tables differ. Do not use the wrong manual for gas pressure settings. Find the exact 36F1 version.
