6. Close drain valve or reconnect plumbing to cold

water supply for the water heater.

7. See "Start Up" procedure before turning on

power.

WINTERIZING

Before beginning winterizing, be sure the power is
turned off to the water heater.  Open all hot water taps
on the boat to relieve the pressure and allow cold
water to cool the water in the system.  Remove both
lines from the heater and allow it to drain.  After it
has drained, blow it out with air pressure, if available.
Pour a quart of nontoxic antifreeze (propylene glycol)
into the hot water fitting of the tank using a funnel
and short length of hose.  

Be sure power remains

off until spring.

When recommissioning in the spring, run water long
enough to insure that all antifreeze has been flushed
out and tank is filled BEFORE TURNING ON
POWER.  Heat exchangers are winterized in
conjunction with the boat’s engine cooling system.

INSTALLATION

Materials Required for Installation (not included
with water heater):
Plumbing

:  3/4" NPT "Tee", check valve, expansion

tank, drain valve, PTFE 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

:  #12-3 stranded cable; circuit breaker (15

amp 120V, 10 amp 240V), wire crimp terminals for
#12 wire, and wire supports/straps.  For model
#17120203 and 17200203 electrical requirements
are:  #10-3 stranded cable; circuit breaker (both legs
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.

Tools needed: 

 Pipe wrench, screw driver, nut driver

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:  Access or hatch must be large enough  for
future servicing and/or replacement.

2. Position heater so that electrical cover plates,

plumbing nipples and heat exchanger fittings are
easily accessible.

3. Using the four mounting holes provided, securely

mount heater to deck or other sturdy flat area.
Stainless steel 5/16"(8mm) bolts or lag bolts with
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
excessive heeling and pitching is expected.  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
requirement of local codes.  A device MUST  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

.

For hot water connections use only pipping, hoses,
tubing, fixtures and connectors rated for hot
water use.
Avoid sharp bends and 90° ells in the plumbing
wherever possible, as they reduce the water flow.
Should copper fittings be desired, DO NOT apply
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.

1.   Install Temperature and Pressure Relief Valve in

area marked "OPENING FOR TEMPERATURE
AND PRESSURE RELIEF DEVICE."  Valve is
included in box separate from the heater.  Use
PTFE tape on the threads.
