This is a photograph of the exterior access door of an Atwood 6-gallon RV water heater, showing the factory instruction/warning label (MPD 90020, dated 3/00) mounted on an RV or trailer sidewall above a spare tire. The label covers three sections: General Water Heater Information (installation per ANSI A-119.2/NFPA 501C, zero-inch clearance to combustibles, references to instruction manual MPD 93756), Pilot Operation (separate lighting procedures for White Rodgers and Robertshaw "Unitrol" gas controls, including 30-second pilot hold times), and Electronic Ignition Operation (remote switch procedure, lockout reset after high-temperature shutdown, and shutdown/servicing steps including removing the red wire from the ECO switch). Caution blocks warn of scalding injury from higher temperature settings and product damage from spider/insect nests obstructing the burner tube, listing symptoms such as yellow or lazy flames and sooting. Additional notes cover the pressure-temperature relief valve (ANSI Z21.22 compliance, never plug or remove), circuit board troubleshooting, and the thermal cutoff in the power supply line. A yellow sticker lists actual recovery rates: 6.2 GPH electric, 11.8 GPH gas, 17.8 GPH gas/electric. U.S. patent numbers and Canada patent 609535 are printed on the label. Painter's tape covers the lower vent area of the door.

Frequently asked questions

How do I light the pilot on an Atwood RV water heater with a White Rodgers control?
Turn lighting control to OFF, wait at least 5 minutes for gas to escape, then turn the knob to PILOT and hold against the stop while lighting the pilot burner. Allow the pilot to burn 30 seconds before releasing the knob, then turn to ON and set the temperature selection lever between warm and hot.
What do I do if the Atwood water heater goes into lockout (indicator light on)?
A lockout occurs if the heater fails to operate due to high water temperature. After the water cools, place the reset switch in OFF for at least 30 seconds, then turn it back ON. If the lockout persists, contact an Atwood Service Center.
What are the recovery rates for this Atwood 6-gallon water heater?
The label lists actual recovery rates of 6.2 GPH on electric, 11.8 GPH on gas, and 17.8 GPH on gas/electric combined.
What clearance from combustible construction does this water heater require?
Minimum clearance is 0 inches from the side, 0 inches from the back, and 0 inches from top and bottom.
What can cause burner problems like a yellow or lazy flame on this heater?
Spiders or insects can build nests in the burner tube causing obstructions. Signs include a change in burner sound, flame changing from hard blue to soft lazy, a very yellow flame, or sooting. The burner tube should be regularly inspected and cleaned.
