IMPORTANT SAFETY INSTRUCTIONS

When using electrical appliances, basic safety precautions to reduce the risk of
fire, electric shock, or injury to persons should be followed, including:

• Read all Instructions before Operating.

• This water heater must be grounded. Connect only to properly grounded circuit.

• Install or locate this water heater only in accordance with the provided installation

instructions.

• Use this water heater only for its intended use as described in this manual.

• Do not use an extension cord set with this water heater.

ENG-0092.6

• Do not operate this water heater if it has a damaged power line, if it is not working

properly, or if it has been damaged or dropped.

• This water heater should be serviced only by qualified service personnel. Contact

nearest authorized service facility for examination, repair, or adjustment.

WARNING:

This is an electrical appliance that requires a specific energy source. Each unit is
manufactured to run on either 120 OR 240 volt circuitry. Be sure you have
purchased the correct unit based on your power source.

This heater is equipped with a heat exchanger so that the water may be heated by the
coolant from your engine. This may cause the water temperature to get excessively
hot unless your unit is equipped with a Temperature Control Valve which holds the
temperature at approximately 140 deg F.

Do not operate this water heater if there is damage to the heater or if not performing
properly. Contact Force 10 for assistance.

The tank and heat exchanger are aluminum. Do not use any chemicals in the heat
exchanger that may cause damage to it. Use only the engine manufacturer’s
recommended coolant. Do not use raw water in heat exchanger circuit. Damage
caused by a damaging chemical or salt reaction is not covered under warranty.

CAUTION

Hydrogen gas is produced in a hot water system served by this heater that has not
been used for a long period of time (2 weeks or more). Hydrogen gas is extremely
flammable. To reduce the risk of injury under these conditions, it is recommended
that the hot water faucet be opened for several minutes at the kitchen sink before
using any electrical appliance connected to the hot water system. When 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
at the time it is open.

NOTE: Small DC electric currents move between boat and shore through the safety
ground wire in the shore cord, causing galvanic damage to your water heater. To
prevent galvanic damage, this product should be used in conjunction with a galvanic
isolator. These devices are inexpensive and easily installed. Galvanic corrosion is not
covered by warranty.

INSTALLATION

CAUTION

To reduce the risk of excessive pressures and temperatures in this water heater,
install temperature and pressure protective equipment required by local codes and no
less than a combination temperature and pressure relief valve certified by a
nationally recognized testing laboratory that maintains periodic inspection of
production of listed equipment or materials, as meeting the requirements for Relief
Valves and Automatic Gas Shutoff Devices for Hot Water Supply Systems, ANSI
Z21.22-1986. This valve must be marked with a maximum set pressure not to exceed
the marked maximum working pressure of the water heater. Install the valve into an
opening provided and marked for this purpose in the water heater, and orient it or
provide tubing so that any discharge from the valve exits only within 6 inches above,
or at any distance below, the structural floor, and does not contact any live electrical
part. The discharge opening must not be blocked or reduced in size under any
circumstances.) For your convenience, this device has already been installed on you

unit.

MOUNTING

1. If you are using the heat exchange feature, locate the water heater as close to the

engine as possible. The heat exchanger port (or TCV inlet if equipped) must be
lower that the coolant output port of the engine.

2. Your unit is equipped with mounting brackets located either on the sides of the

tank or the front and back of the tank. Use stainless steel screws to securely fasten
the heater.

PLUMBING

1. Connect cold water supply and hot water outlet to the heater as indicated on the

front of the tank. (The tank is supplied with 1/2” NPT Female fitting) Force 10
recommends the installation of a check valve on the cold water inlet. Seal all pipe
fittings with Teflon tape or Loctite thread sealant.

Thermal Expansion: When a Water Heater is installed in a closed water­ supply system, such as one having a back flow preventer in the cold water
supply, means shall be provided to control thermal expansion.

2. The heat exchanger inlet or TVC inlet (if equipped) and the outlet is a 5/8” hose

barb fitting. Connect hoses to the hose barb fitting using stainless steel hose
clamps.

3. If your unit is equipped with a TCV (Temperature Compensation Valve) the

coolant loop to the water heater exchanger must be an auxiliary loop in the engine
coolant circulation system. The TCV can not be installed inline with the engine
coolant system. Figure 1 on page 5
