WARNING: Raritan Engineering Company, Inc. recommends that a qualified person or electrician install
and service this product. Equipment damage, injury to personnel or death could result from
improper installation. Raritan Engineering Company, Inc. accepts no responsibility or liability
for damage to equipment, injury to personnel or death that may result from improper installation
or operation of this product.
WARNING: Hazard of Shock or Fire - Always use recommended fuse/circuit breaker and wire size. Always
make sure that unit is properly grounded to AC grounding conductor (green). Do not use an
extension cord. Contact a qualified electrician to have wiring properly installed.
Hazard of Scalding - Water temperature over 125°F (52°C) can cause severe burns
instantly. Supervise children when using hot water. Water heaters equipped with engine
heat exchanger can heat water to very high temperature. Thermostatic mixing valve
should be installed before point of use to limit the water temperature to maximum
of 125° F (52° C). For more information, see your qualified technician.
WARNING: Hydrogen gas can be produced in a hot water system served by this heater that has not been used
for a long period of time (generally 2 weeks or more). Hydrogen gas is extremely flammable.
To reduce the risk of injury under these conditions, it is recommended that a hot water faucet be
opened for several minutes before using any electrical appliance connected to the hot water
system. If hydrogen is present, there will probably be an unusual sound such as air escaping
through the pipe as the water begins to flow. There should be no smoking or open flame near
the faucet when it is initially opened.

for repairs.

DESCRIPTION

Raritan Water Heaters are constructed with high quality components: a glass lined tank, high density
non-CFC foam insulation, noncorrosive polymer jacket and an adjustable Thermostat. Models with an
internal Heat Exchanger heat water from an external source. Dockside hot water recovery rate is 13 gallons
(49.2 liters) per hour. (18 gallons [68.1 liters] per hour for model #17120203 or 17200203 with 4500 watt/
240V heating element). Ground terminal and replaceable Anode are built in. Temperature and Pressure
Valve rated at 75 psi (517 kPa) 210°F (99°C) is included for on-board nominal working system pressure
of 50 psi (345 kPa) maximum. If working pressure is 60 psi (414 kPa) then a temperature and pressure
valve rated at 100 psi (790 kPa) is available (part WH3A). If operating pressure exceeds 60 psi (414 kPa)
then use a pressure reducing valve for entire plumbing on the boat. The water heater is ignition protected
as per United States Coast Guard regulation 33 CFR 183.410.
