No water is available when a fixture is opened.

The hot water is not the correct temperature.

Water takes time to become hot when turning the hot water fixture.

The water is too hot.

• Is the water supply cut off?

• Is the heater frozen?

•Is the hot water fixture sufficiently open?

• Have you allowed enough time for the cold water in the pipes to drain out?

•Are the gas and water supply valves fully open?

• Is the water temperature setting appropriate?

(

p.12 and p.13)

• If the water supply temperature is high, it is possible

for the temperature to be higher than the temperature set on the remote controller.

• If only a small amount of hot water is demanded, it is

possible for the temperature to be higher than the temperature set on the remote controller.

• If the supply water goes through a solar pre-heating

system, it is possible for the temperature to be higher than the temperature set on the remote controller.

Troubleshooting-2

Temperature

The water is not hot enough.

The water is cold when only a single fixture is open.

Fluctuations in hot water temperatures.

Amount of Hot Water

The amount of hot water at a certain fixture is not constant.

•Are the gas and water supply valves fully open?

• Is the water temperature setting appropriate?

p.12 and p.13)

(

• If the amount of hot water required is very high, it is possible for the temperature to be lower than the temp erature set on the remote controller. Decrease the amount of water passing through the unit and the temperature should stabilize.

• The unit will not heat the water if the flow rate is less than

0.7 gallons per minute. Open the fixture more or open other fixtures so that a greater flow passes through the unit, and the unit should begin heating again.

• Set water temperature at 115°F to 120°F. This will allow you to use a higher flow of hot water thus meeting the minimum flow requirement of 0.7 gpm.

•Clean the water filter of any debris (

•When hot water is demanded at other fixtures, the amount available may be reduced. The maximum flow available from this unit is 6.9 GPM at a 45°F temp. rise.

• Pressure fluctuations and other plumbing conditions can cause the temperature and pressure at a fixture to be unstable, but it should stabilize after a short time.

• There are some types of hot water taps that discharge large

volumes of hot water initially, but stabilize after time.

•To keep the temperature stable, the heater limits the amount of water that can flow through it to a small amount initially, but the amount increases over time.

p.20)

The amount of hot water in the tub is less/more than the set amount.

The flow meter alarm does not sound even when filled to the set amount.

Amount of hot water available has decreased over time.

•When hot water is used for other fixtures while filling the bath tub, the tub will not fill as much.

• If there is water in the tub already, or when filling is stopped and resumed, the tub will fill more.

•

The flow meter alarm is set to sound when hot water is continuously discharged for the set volume of water. If mixing valves are used, or if cold water is mixed with hot water at the fixture, the tub will fill more than the setting of the flow meter alarm.

• Is the water drain valve filter clogged? (

p.20)

Remote Controller

The light on the power button does not come on.

The water temperature changes after a power failure or when the power is disconnected.

The fan can be heard after operation is stopped.

A motor can be heard when turning the unit ON or OFF, when opening or closing a fixture, or after the unit has been running for a while.

• Has there been a power failure?

•Is the power connected properly?

• The temperature setting and the flow meter alarm setting may both need to be reset after a power outage.

Before Installation

Warning

Precautions on Vent Pipe Replacement

• The vent system will almost certainly need to be replaced when this appliance is being installed. Use vent pipe that is listed to UL 1738 for Category III appliances for the exhaust venting. Category III listed vent pipe is suggested for the air supply pipe also, but other materials may be acceptable. Consult local codes. * If Category III listed vent pipe is already installed, check for punctures, cracks or blockages and

consult with the vent pipe manufacturer before reusing.

Use Approved Vent Materials

• Use only vent materials that are listed to UL 1738 for Category III appliances for the exhaust venting of this appliance. Improper venting may result in fires, property damage or exposure to Carbon Monoxide.

Snow Precaution

• If this product will be installed in an area where snow is known to accumulate, protect the vent termination from blockage by snow drifts or damage from snow falling off of roofs.

Caution

Check the Gas

• Check that the rating plate indicates the correct type of gas. Check that the gas supply line is sized for 194,000 Btuh for this unit.

Check the Power

• The power supply required is 120V AC, at 60Hz. Using the incorrect voltage may result in fire or electric shock.

Do Not Use Equipment for Purposes Other Than Those Specified

• Do not use for purposes other than increasing the temperature of the water supply, as unexpected accidents may occur as a result.

Check Water Supply Quality

• If the water supply is hard, acidic or otherwise impure, treat the water with approved methods in order to ensure full warranty coverage.

Use Extreme Caution if Using With A Solar Pre-Heater

• Using this unit with a solar pre-heater can lead to unpredictable output temperatures and

possibly scalding. If absolutely necessary, use mixing valves to ensure output temperatures do

not get to scalding levels. Do not use a solar pre-heater with the quick-connect multi-system.

Checkup

• Check the fixing brackets and vent pipe yearly for damage or wear. Replace if necessary.

Choosing Installation Site

* Locate the appliance in an area where leakage from the unit or connections will not result in damage

to the area adjacent to the appliance or to the lower floors of the structure. When such locations cannot be avoided, it is recommended that a suitable drain pan, adequately drained, be installed under the appliance. The pan must not restrict combustion air flow.

Caution

• The water heater is designed for indoor installation only. Never install it outdoors or in a bathroom, it may be damaged or a fire may be caused.

• Consult with the customer concerning the location of installation.

•Avoid places where fires are common, such as those where gasoline, benzene and adhesives are handled, or places in which corrosive gases (ammonia, chlorine, sulfur, ethylene compounds, acids) are present. This may cause incomplete combustion or failures.

• Locate the vent terminal so that there are no obstacles around the termination and so that exhaust can't accumulate. Do not enclose the termination with corrugated metal or other materials.

•Install the water heater in an area that allows for the proper clearances to combustible and noncombustible construction. Consult the rating plate on the appliance for proper clearances.

• Do not install the water heater in a place where it may be threatened by falling objects, such as under shelves.

• The water heater must be installed in a place where supply and exhaust pipes can be installed as directed.

•Do not install the water heater where the exhaust will blow on outer walls or material not resistant to heat. Also consider the surrounding trees and animals.

The heat and moisture from the water heater may cause discoloration of walls and resinous materials, or corrosion of aluminum materials.

• Avoid installation above gas ranges or stoves.

• Avoid installation between the kitchen fan and stove. If oily fumes or a large amount of steam are present in the installation location, take measures to prevent the fumes and steam from entering in the equipment.

•Avoid installation in places where dust or debris will accumulate. Dust may block the air-supply opening, causing the performance of the fan motor to drop and incomplete combustion to occur as a result.

• Install in a location where the exhaust gas flow will not be affected by fans or range hoods.

• Take care that noise and exhaust gas will not affect neighbors.

• Avoid installation in places where special chemical agents (e.g., hair spray or spray detergent) are used.

Ignition failures and malfunction may occur as a result.

• Before installing, make sure that the exhaust flue termination will have the proper clearances according to the National Fuel Gas Code (ANSI Z223.1).

6. Installation Clearances

Caution

Before installing, check for the following:

Install in accordance with relevant building and mechanical codes, as well as any local, state or national regulations.

Item

10. Water Piping

This appliance is suitable for potable water and space heating applications. Do not use this appliance if any part has been underwater. Immediately call a qualified service technician to inspect the appliance and replace any part of the control system and gas control which has been under water.

If the water heater is installed in a closed water supply system, such as one having a backflow preventer in the cold water supply line, means shall be provided to control thermal expansion. Contact the water supplier or a local plumbing inspector on how to control this situation.

A pressure relief valve must be installed near the hot water outlet that is rated in accordance with and complying with either The Standard for Relief Valves and Automatic Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22, or The ANSI/ASME Boiler and Pressure Vessel Code, Section IV ( Heating Boilers ). This pressure relief valve must be capable of an hourly Btu rated temperature steam discharge of 194,000 Btuh. Multiple valves may be used. The pressure relief capacity must not exceed 150 psig. No valve shall be placed between the relief valve and the water heater. The relief valve must be installed such that the discharge will be conducted to a suitable place for disposal when relief occurs. No reducing coupling or other restriction may be installed in the discharge line. The discharge line must be installed to allow complete drainage of both the valve and the line. If this unit is installed with a separate storage vessel, the separate vessel must have its own temperature and pressure relief valve. This valve must also comply with The Standard for Relief Valves and Automatic Gas Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22. (in the U.S. only). A temperature relief valve is not required, but if one is used, do not install the valve with the probe directly in the flow of water. This may cause unwarranted discharge of the valve.

Piping and components connected to the water heater shall be suitable for use with potable water. Toxic chemicals, such as those used for boiler treatment, shall not be introduced into the potable water. A water heater used to supply potable water may not be connected to any heating system or components previously used with a nonpotable water heating appliance. When water is required in one part of the system at a higher temperature than in the rest of the system, means such as a mixing valve shall be installed to temper the water to reduce the scald hazard.

• Flush water through the pipe to clean out metal powder, sand and dirt before connecting it.

• Take appropriate heat insulation measures (e.g., wrapping with heat insulation materials, using electric heaters) according to the climate of the region to prevent the pipe from freezing.

•

Use a union coupling or flexible pipe for connecting the pipes to reduce the force applied to the piping.

• Do not use piping with a diameter smaller than the coupling.

• When feed water pressure is too high, insert a depressurizing valve, or take

• Avoid using joints as much as possible to keep the piping simple.

• Avoid piping in which an air holdup can occur.

• Use approved piping materials.

• If installing the unit on a roof: If the unit is installed on a roof to supply water to the levels below, make sure that the water pressure supplied to the unit does not drop below 29 psi. It may be necessary to install a pump system to ensure that the water pressure is maintained at this level. Check the pressure before putting the unit into operation. Failing to supply the proper pressure to the unit may result in noisy operation, shorter lifetime of the unit, and may cause the unit to shut down frequently.

of the plumbing. Observe all applicable codes.

water hammer prevention measures.

Supply water piping

• Do not use PVC piping.

• Mount a check valve and a shut off valve (near the inlet).

• In order for the client to use the water heater comfortably, 98.1 to 491 kPa (14 to 70 PSI) of pressure is needed from the water supply. Be sure to check the water pressure. If the water pressure is low, the water heater cannot perform to its full capability, and may become a source of trouble for the client.

Drain piping

• Expansion water may drop from the pressure prevention device and wet the floor. If necessary, provide drain piping or use a drain hose to remove the water.

Hot water piping

•Do not use lead or PVC piping.

• The longer the piping, the greater the heat loss. Try to make the piping as short as possible.

•Use mixing valve with a low water resistance. Use shower heads with low pressure loss.

• If necessary, use a pump or other means to ensure that the supply water pressure to the inlet of the heater does not fall below 29 PSI when the maximum amount of water is being demanded. Also install a pressure meter on the inlet. If this is not done, local boiling will occur inside the water heater causing abnormal sounds and decreasing the durability of the heat exchanger.

Before Installation

Compatibility Check

• Make sure that the vent terminal is compatible with the product it will be installed with. If an improper terminal is used, a fire hazard will be created.

Choosing Installation Site

• Maintain the proper clearances to combustibles

The heat and moisture from the water heater may cause corrosion of aluminum materials.

• Install the vent terminal so that it is easily accessible for maintenance from both the indoors and the outdoors.

• Install the vent terminal so that all exhaust is directed to and all intake air is taken from the outdoors.

• Steam or condensed water may drip out of the vent terminal. Dispose of this condensed water according to local codes and in order to prevent injury or property damage.

Check Wall Thickness

• This vent terminal model has four different sizes. Choose the correct model to fit the thickness of

the wall that the terminal will pass through.

Caution

Model name

VT4-TL-5 3.5" to 5"

VT4-TL-8 5" to 8.5" VT4-TL-14 8.5" to 15" VT4-TL-27 15" to 27"

Vent Pipe Replacement Precautions

• The vent system will almost certainly need to be replaced when this appliance is being installed. Use vent pipe that is listed to UL 1738 for Category III appliances for the exhaust venting. Category III listed vent pipe is suggested for the air supply also, but other materials may be acceptable. Consult local codes.

* If Category III listed vent pipe is already installed, check for punctures, cracks or blockages and

consult with the vent pipe manufacturer before reusing.

* Make sure the vent pipe is compatible with the vent terminal before installation.

• Do not extend the vent pipe longer than the maximum limits as stated in the installation manual. Vent lengths longer than the stated maximum are dangerous and may cause a fire or explosion

• Avoid installing the vent pipe in an enclosure if possible.

• Do not install a damper on the intake or exhaust pipe.

• Do not install the vent terminal indoors.

• Use 4" diameter vent pipe from the water heater all the way to the vent terminal.

•Use only UL 1738 listed Category III vent pipe.

•Make sure that the vent pipe is sealed gas tight and is securely connected so that it cannot be easily dislodged.

•Make the vertical section of the vent pipe as short as possible (3 ft. or less is suggested)

• Support the vent pipe at appropriate intervals with hangers. Consult the vent pipe manufacturer's installation instructions for the proper interval.

• Steam or condensed water may drip out of the vent terminal. Dispose of this condensed water according to local codes and in order to prevent injury or property damage.

Protection from condensed water accumulation

• Slope the intake and exhaust pipes at a 1/50 grade down towards the termination.

• Avoid sags or slack in the vent pipe.

• If the vent terminal will be installed higher than the water heater, make the vertical section directly above the water as short as possible, and slope down to the terminal. Do not have another vertical section after the horizontal section begins.
