The Next Generation of Atwood Water

IntegratedGas/Electric

Controls!

Having hot water has neverbeen easier with the nextgeneration of CombinationGas/Electric WaterHeaters from AtwoodMobile Products.

Microprocessor Technology• Gas and Electric Lockout• 3 Try Ignition• 2 Amp Automotive Fuse • Circuit Board is compatible with

past gas powered water heaters

Conveniently Located T-Stat and ECO• T-Stat and ECO located in front• No switches in rear of heater

New Dual Switch Panel• Eliminates need for 120-volt remote

switch• Electric element powered by 12-volt relay• Can be wired to low voltage monitor

panel switches

Depth Dimensions of 6-gallon water heaterreduced by 1/2”

Electronic IgnitionConvenience and safety. A simple flipof the switch from inside the coachturns the water heater on or off.

Advanced Designs Deliver Hot Water Faster

Pilot Re-Light IgnitionWorry-free design. Light it once andforget it. Automatically re-lights ifwind or other conditions extinguish the flame.

Pilot IgnitionEconomical, time-tested performance.The pilot is manually lit when the destination is reached and hot water is available in less than one half hour.

Greater OverallEfficiencyIncorporating advanced design concepts, Atwood water heaters arethe most efficient, versatile heatersavailable for recreation vehicles—making it easier than ever to travelwith the comforts of home.

LightweightNever before has the issue of weightbeen as important as it is today. Atdry weight, Atwood six-gallon modelsare 14 pounds lighter than competi-tive models; 10 gallon models are 30pounds lighter.

Fuel-Saving FlexibilityAtwood water heaters operate on L.P.gas. In addition, there are modelsthat operate from an electric source,with an engine coolant heat exchangeror both. With the electric option, theheater can be run either off an electri-cal hook up or a generator. The heatexchanger safely transfers otherwise

wasted energy from the engine-coolingsystem of a motorized coach to thewater heater during travel. When youarrive at your destination, hot water isavailable immediately. You saveenergy, time and money!

Additional Features Include:Serviceable—98% of all serviceable components are accessed through theexterior door. Access means that if you do need service, it’s easy and no onehas to enter your coach to perform thework. Service time is reduced and youhave peace of mind when you travel.

Multiple protection features—The hightemperature limit switch, thermostat andpressure and temperature relief valve,prevent problems before they happen.An externally sealed combustion chamberkeeps the outside of the unit cleaner.

Pre-skin installation—Atwood waterheaters can be set in place, connectedand tested on the coach floor before set-ting the sidewalls in place. This givesmanufacturers more flexibility in con-struction.

Matching access doors—Atwood accessdoors are painted with tough, durablepaint in a variety of popular colors. Thisensures that the all important exteriorlook and styling is kept clean anduncluttered looking.

Mounting options—All 6 and 10 gallonmodels can be flush mounted into theRV sidewall for a more integrated,attractive appearance. All 6 gallonmodels fit into a single 125/8" x 161/4"

cutout size. All 10 gallon units usethe same cutout width as the 6 gallonmodels and require only an additional 3" of cutout height.

Atwood has designed andmanufactured water heaters forrecreation vehicles for morethan 30 years. Our engineering,manufacturing and applicationexpertise have been honed bytime and the experience of sup-plying millions of water heaters.Almost 20 years ago, Atwoodapplied this specialized knowl-edge to meet the needs of themarine industry. In doing so,we designed the water heatersthat have become the standardin the boating industry.

PerformanceOur water heaters have beendesigned not only to heat waterquickly and efficiently, but to alsodeliver every ounce of usable hotwater possible from the tank.Atwood water heaters perform reli-ably, assuring customer satisfac-tion and full use of hot water bene-fits designed in your pleasure boats.

Additional Features Include:Forgiving incalloy element—Each Atwood electric water heater isequipped with a high quality 120 volt/1400 watt incalloy® heating elementdesigned to withstand accidentaloperation in an empty tank. A 220

volt/1500 watt version is also available.The electrical system is ignition pro-tected and meets UL specifications.

Safe and efficient heat exchangers—To quickly heat water when underpower, Atwood has developed effi-cient heat exchangers. Each heatexchanger is specifically designed forthe water heater’s capacity resultingin heat up times superior to competi-tive models. These heat exchangersensure safety by using a unique dou-ble tube construction which prevents

any possibility of engine coolant con-taminating the fresh water system.

Corrosion resistant exterior—Thecasing of every Atwood electric waterheater is constructed from corrosionresistant materials and then carefullypainted to stand up against the mostcorrosive marine environments.Special attention to detail on edgesand corners helps assure greater handling safety.

Designed for installation flexibility—The cubic shape and lightweight aluminum-alloy tank offers greaterflexibility for water heater locationin floor plans.

Compliance—All 220/vac modelscarry the CE mark and complywith ISO 8846 “IgnitionProtection.” A unit for installation in a 75 P.S.I. system is available. Note: volume will be slightly less.

Atwood Marine Water Heaters

With casings constructed of highlycorrosion-resistant aluminum, Atwoodwater heaters resist even the harshestmarine environments.
