The Aqua-Hot 375LP is a hydronic (water based) heating
system, and a tank-less hot water system.
The heating system provides moist, quiet, comfortable, inte-
rior heat with up to three separate, thermostatically-
controlled temperature zones, and prevents tank and line
freezing in the bays. The tank-less hot water system
produces 115 gallons per hour of continuous, on-demand hot
water.
This TribridHot™ designated system uses one or a combina-
tion of heat sources to heat FDA-approved Generally Recog-
nized as Safe (GRAS) propylene glycol based antifreeze
solution in the Aqua-Hot’s boiler tank. The 375LP features a
120 Volt-AC, 1500 Watt electric element, and a 12 Volt-DC
powered propane burner.
When AC power is available, plug in. When dry camping,
use the propane fuel source. The electric power and propane
fuel sources can be used separately or together.
This Installation Manual is designed to aid in the installation
process of the Aqua-Hot 375LP Hydronic Heating System by
a trained and experienced technician.
Please note that all Danger, Warning, Caution, and Note
boxes, appearing as needed throughout this manual, must be
reviewed and adhered to during the installation procedure in
order to avoid potential hazards, which could result in injury,
death, product damage, or property damage.
