WARNING: HazardofShockorFire-Alwaysuserecommendedfuse/circuitbreakerandwiresize. Always
make sure that unit is properly grounded to AC grounding conductor (green).
Hazard of Scalding - Water temperature over 125°F (52°C) can cause severe burns instantly.
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.

INSTALLATION
MaterialsRequiredforInstallation(notincluded
with water heater):
Plumbing: 3/4"NPT"Tee",checkvalve,expansion
tank, drain valve, teflon tape, vacuum relief valve
and shut-off valve. For hot water connections use
hose or plastic tubing rated for hot water use. If
system will be used with dockside water supply, a
pressure regulator valve, set to match boat pressure
system is also required. See Fig. #1 for typical
installation.
Electrical: #12-3strandedcable;circuitbreaker(15
amp 120V, 10 amp 240V), wire crimp terminals for
#12 wire, and wire supports/straps. For model
#17120203 and 17200203 electrical requirements
are: #10-3strandedcable;circuit breaker(bothlegs
simultaneous 20 amp 240V), wire crimp terminals
for #10 wire and wire supports/straps.
Hardware: Four 5/16" (8mm) stainless steel bolts
or lag bolts, flat washers and hose clamps. For 12
and 20 gallon models: stainless steel straps and
fasteners.
Toolsneeded: Pipewrench,screwdriver,nutdriver
and wrench(es) for mounting bolts or lag bolts.
MOUNTING THE HEATER
1. Select an area where the heater will not be
subjected to water spray (especially salt water).
NOTE: Accesswayorhatchmustbelargeenough
for future servicing and/or replacement.
2. Position heater so that electrical cover plates,
plumbingnipplesandheatexchangerfittingsare
easily accessible.
3. Usingthefourmountingholesprovided,securely
mount heater to deck or other sturdy flat area.
Stainlesssteel5/16"(8mm)boltsorlagboltswith
flat washers should be used to properly support
the strain of a full unit while the boat is rocking.
Raritan 12 and 20 gallon water heaters require
auxiliary bracing, when the boat is in heavy seas.
This is also recommended for the 6 gallon models if
excessiveheeling andpitching isexpected. See Fig.
#3a for optional bracing.
PLUMBING
CAUTION: To reduce the risk of excessive
pressure and temperature in this water heater,
temperature and pressure sensitive protective
equipment must be installed that meet the
requirementoflocalcodes. AdeviceMUST NOT
be installed unless it is certified by a nationally
recognized testing laboratory and meets the
requirements for Relief Valves and Automatic
Shut-off Devices for Hot Water Supply Systems,
ANSI Z21.11-1979. The relief valve must not be
blocked or restricted under any circumstances.
Forhotwaterconnectionsuseonlypipping,hoses,
tubing, fixtures and connectors rated for hot
water use.
Avoid sharp bends and 90° ells in the plumbing
whereverpossible,asthey reduce the waterflow.
Shouldcopperfittingsbedesired,DONOTapply
direct heat to the 3/4'' nipples protruding from
the heater. They contain a nonmetallic lining
which will be destroyed by heat. Solder fittings
first, then attach to water heater.

2. Install a “tee” in the cold water supply line.
3. From the “tee” run a line to the heater, this line
MUST have a vacuum relief valve (such as
Watts Model N36) installed to prevent back
siphoning which could cause the tank to empty
and element to burn out (see Fig. #1). The
vacuum break must be mounted higher than the
hot water outlet from the water heater.
4. Connect this cold water supply line to the lower
heater connection marked COLD.
5. Installation of a drain valve between cold water
line and heater is recommended (see Fig. #1).
6. Atwogallonexpansiontankshouldbeinstalled
in the cold water line to avoid pressure buildup
due to thermal expansion of water.
7. The upper heater connection, marked HOT, is
connected to the hot water faucets, shower, etc.
8. Securealllinestotheboat’sstructureatfrequent
intervals.
9. Be sure the safety relief valve is connected to
hose or piping so that overflow can run
unrestrictedintothebilgeandthatabilgepump
is in place. Any discharge from the hose must
exit within six inches above or any distance
below the structural floor and cannot contact
any live electrical part. The relief valve must
not be blocked off or reduced in size.
10. For models with heat exchangers see Fig. #4.
ELECTRICAL PREPARATION
All wiring should be done in accordance with
ABYC E8, AC wiring standard.
1. Install a 15 amp (10 amp for 240V AC or 20
amp for model #17120203 and 17200203)
Circuit Breaker in the 120V AC service line to
the water heater.
2. Use ONLY STRANDED #12-3 (#10-3 for
model #17120203 and 17200203) cable to the
heater. NEVERuse solid(ROMEX-type) wire
on a boat; vessel vibration causes breakage due
to metal fatigue (see U.S. Coast Guard CFR
Title 33, Part 183.423).
3. Securewireatintervals of18"(45.7cm). Allow
about24''(61cm)ofextrawiretomakenecessary
