Richmond Water Heater Model 6g40-36f1 Manual -
Manual Diagnosis: Bacteria reaction with the anode rod. Fix: The manual suggests temporarily turning the temperature to 160°F (VERY HOT) for 2 hours to kill bacteria, then reducing back to 120°F. Warning: Do not use water during this process.
The rating plate is a silver sticker located near the gas control valve or on the side of the tank. It will list the full model number (6G40-36F1) and the serial number. Do not confuse this with similar models like 6G40-36F2 or 6G50-36F1 – even minor differences affect parts compatibility.
If you are searching for the manual because you need warranty service, your serial number matters. For a 6G40-36F1:
If your unit is older than 6 years from that date, the warranty is void, but the manual’s maintenance section is still critical.

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.
