OWNERS MANUAL
375 LP

Comfort Zone #1: Comfortable Cabin Heat.
Get heat where you want it, when you want it! Because the Aqua-Hot system heats by zones, your bed-
room, living room, and bathroom can be custom temperatures. And don’t hesitate to crank up the heat,
because the Aqua-Hot system doesn’t remove moisture from the air. From now on, you will have to
blame the dry skin and itchy eyes on Mother Nature!
Comfort Zone #2: Quiet Operation
Say goodbye to rude awakenings from the forced air furnace, you’re an Aqua-Hot owner now! The Aqua-
Hot is quiet when operating, so you’ll never have to turn up the TV, yell across the room, or have an inter-
rupted night of sleep again due to your heating system.
Comfort Zone #3: Continuous, On-Demand Hot Water
Take long, guilt free showers knowing there is no recovery time for the next shower or load of laundry.
The freedom to take a shower when you want makes your RV experience feel much more like home.
Comfort Zone #4: Low Emissions
Aqua-Hot’s new low emission systems are fumeless and odorless. It’s good for you,
good for your neighbor, and good for the environment.
Comfort Zone #5: Over 160 Factory-Trained Service Centers
You won’t need to service your Aqua-Hot often, but when you do, you can be confident in our Certified
Service Centers that are close by and trained to assist you with all of your Aqua-Hot specific needs.
Comfort Zone #6: Adds Value
The NADA Recreational Vehicle Guide lists Aqua-Hot as adding thousands of dollars to the value of an
RV. That value will pay off when it’s time to trade up or sell.
Comfort Zone #6: Low fuel Costs
Aqua-Hot’s TribridHot technology powers the Aqua-Hot system by pulling heat from one or a combination
of heat sources. When shore power is available, simply plug it in. When dry-camping or in very cold
conditions, use the Propane Burner.

age.

aforementioned conditions are present will
result in serious damage to the Aqua-Hot’s
Domestic Water Heating System, requiring
complete system replacement not covered
under the Aqua-Hot warranty.
