INSTALLATION

All gas water heaters require careful and correct installation to ensure safe and efficient

operation. This manual must be followed exactly. Read the “Safety Guidelines” section at the

beginning of this manual.

The warranty will not cover damage caused by water quality. Water

hardness that leads to scale formation and/or corrosion may

affect/damage the water heater. Hard water scaling and/or corrosion must

be avoided or controlled by proper water treatment.

The manufacturer recommends using the direct-vent kit, when the

water heater is installed in a beauty salon. Some chemicals used in a

beauty salon may affect the flame sensor. Water heater may not work

properly.

Although this water heater is designed to operate with minimal sound, the

manufacturer does not recommend installing the unit on a wall

adjacent to a bedroom, or a room that is intended for quiet study or

meditation, etc.

Locate your heater close to a drain where water leakage will not do damage

to surrounding areas. As with any water heating appliance, the potential for

leakage at some time in the life of the product does exist. The manufacturer

will not be responsible for any water damage that may occur. If you install a

drain pan under the unit, ensure that it will not restrict the combustion air

flow.

The manufacturer does not recommend installing unit in an attic due

to safety issues. If you install your water heater in an attic:

Make sure your unit will have enough combustion air and proper

ventilation.

Keep the area around your water heater clean. When dust collects on

the flame sensor, the water heater will shut down on errors.

If the above conditions cannot be met, use the direct-vent conversion kit

WARNING

CAUTION

- 6 -

GENERAL

1. The manifold gas pressure is preset at the factory. It is computer controlled and should

not need adjustment.

2. Maintain proper space for servicing. Install the unit so that it can be connected or

removed easily. Refer to p. 8 and p. 9 for proper clearances.

3. The electrical connection requires a means of disconnection, to terminate power to the

water heater for servicing and safety purposes.

4. If you will be installing the unit in a contaminated area with a high level of dust, sand,

flour, aerosols or other contaminants/chemicals, they can become airborne and enter

and build up within the fan and burner causing damage to the unit. In those

environments (e.g. residential or commercial laundry facilities, hair salons, pet salons,

chemical plants etc.), please purchase the optional direct-vent conversion kit and

convert the water heater to a sealed combustion unit. Direct venting allows the water

heater to draw fresh intake air from the outside. The warranty will not cover damage

caused to the unit due to installation in a contaminated environment that has not been

converted using the direct-vent conversion kit.

5. Particles from flour, aerosols, and other contaminants may clog the air vent or reduce

the functions of the rotating fan and cause improper burning of the gas. Regularly ensure

that the area around the unit is dust- or debris-free; regular maintenance is

recommended for these types of environment.

6. Do not install the unit where the exhaust vent is pointing into any opening in a building or

where the noise may disturb your neighbors. Make sure the vent termination meets the

required distance by local code from any doorway or opening to prevent exhaust from

entering a building (refer to p. 14).

INCLUDED ACCESSORIES

Check that the installation manual, the communication cable, and the product registration card

are included with the unit.
