FVIR technology equipped with flame arrestor

This water heater is equipped with the new FVIR technology. In the event that gasoline or other flammable vapours and liquids are improperly stored in the area where the water heater is located, the flame arrestor will prevent these combustible vapours from igniting outside of the water heater.

Activation of the FVIR technology occurs when flammable vapours are drawn into the combustion chamber of the water heater and ignite. If flammable vapours are detected:

• DO NOT try to light any appliance.

• DO NOT touch any electrical switch, DO NOT use any phone in your building.

• From a neighbour’s phone, immediately call your gas supplier. Follow the gas supplier’s instructions.

• If you cannot reach your gas supplier, call the fire department.

After the flammable vapours have been evacuated, contact a qualified service technician or the manufacturer for further instructions. Replacement of a FVIR technology equipped water heater due to a flammable

vapour shutdown is not covered under the terms of the Standard Basic Limited Warranty.

Many safety related messages have been provided in this manual and on your water heater. Always read and obey all safety messages. These messages will point out the potential hazard, tell you how to reduce the risk of injury, and tell you what will happen if the instructions are not followed.

This is the safety alert symbol. This symbol alerts you to potential hazards that can kill or hurt you and others. All safety messages will follow the safety alert symbol and either the word “DANGER” or “WARNING”.

Serious injury or death can occur if you do not follow the instructions immediately.

Serious injury or death can occur if you do not follow the instructions.

DO NOT use this water heater if any part has been under water. Immediately call a qualified service technician to inspect the water heater and to replace any part of the control system and any gas control which has been under water. Failure to follow this instruction can result in property damage, personal injury, or death.

INSTALLATION INSTRUCTIONS

IMPORTANT

These instructions have been written as a guide for the proper installation and operation of your water heater, and the manufacturer of this water heater will not accept any liability where these instructions have not been followed. However, for your safety and to avoid damage caused by improper installation, this water heater must be installed by a Certified Licensed Professional, and meet all local codes or, in the absence of local codes, CSA B149.1 Natural Gas and Propane Installation Code, in Canada, and/or the National Fuel Gas Code, ANSI Z223.1, in the United States.

Before proceeding with the installation instructions:

1) Inspect the water heater and its component parts for possible damage. DO NOT install or attempt to

repair any damaged component parts. If you detect any damage, contact the dealer where the water heater was purchased or the manufacturer listed on the warranty card.

2) Verify that the type of gas being supplied corresponds to that which is marked on the rating plate and gas control of the water heater.

Altitude

Input rating of this water heater is based on sea level operation. At higher elevations, the actual input rate will be lower than the value listed on the rating plate due to the natural derating of natural gas and propane. DO NOT attempt to adjust the input rate by changing the manifold pressure. Refer to the rating plate on the water heater for the certified elevation at wich your specific model can be installed.

Failure to install a water heater suitable for the altitude at the location it is intented to serve, can result in improper operation of the appliance resulting in property damage and/or producing carbon monoxide gas, which could result in personal injury or death.

Location

The water heater should be located as close as possible to the chimney and to the main use of hot water. This location must not be subject to freezing temperatures. The water heater should be positioned, so that there is easy access to the burner, gas control, and drain valve. It must be located close to a suitable free-flowing floor drain. Where a floor drain is not adjacent to the water heater, a suitable drain pan must be installed under the water heater (see Figure 8). In Canada, according to the National Plumbing Code, this drain pan should be at least two (2) inches (5.1 cm) larger than the diameter of the water heater and at least one (1) inch (2.5 cm) deep, providing access to the drain valve. Local codes may be more rigorous. This pan must not restrict the flow of ventilation and combustion air. This pan must be piped to a suitable drain to prevent damage to property in the event of a water leak from the piping, the relief valve, or the water heater.

Sooner or later, all water heaters leak. The manufacturer, based on national building codes, has given the necessary instructions to prevent damage to the building. Under no circumstances is the manufacturer to be held liable for any water damage in connection with this water heater.

This water heater is approved for installation on either a combustible or non-combustible floor. However, should this water heater be installed directly on carpeting, such carpeting must be protected by a wood or metal panel beneath the water heater. This panel must extend at least three (3) inches (7.62 cm) beyond the width and depth of the water heater. Should the water heater be installed in an alcove or closet, the entire floor area must be covered by the panel.

Minimum Clearances

The minimum clearances from combustible material for this water heater are: Two (2) inches (5.1 cm) from the sides and rear, four (4) inches (10.2 cm) from the front, and eighteen (18) inches (45.7 cm) from the top (see Figure 1).

Combustion and Ventilation Air Supply

In order for the water heater to operate properly, it must be supplied with an uninterrupted flow of clean combustion and ventilation air. The area around the water heater must always be kept clear and the combustion air intake holes at the bottom of the water heater must never be blocked. An inadequate supply of air to the water heater will produce a bright yellow burner flame causing sooting in the combustion chamber, on the burner, and in the flue tube. This can result in damage to the water heater and serious bodily injury, if not corrected.

Combustion and ventilation air requirements are determined by where the water heater will be located. Water heaters are installed in either open (unconfined) spaces or smaller (confined) spaces, such as closets or small rooms.

Figure 2

In Canada refer to CSA B149.1 and local codes for detailed information.

The enclosure in which the water heater is installed shall be provided with two (2) permanent openings of one (1) square inch per 1,000 Btuh (22.0 cm²/ kW) of the total input of all appliances and shall communicate directly with one or more rooms of sufficient volume, so that the combined volume of all spaces meets the criteria for an unconfined space for all the appliances installed in that enclosure.

One opening shall be located not more than

eighteen (18) inches (45.7 cm) or less than six (6) inches (15.2 cm) above the floor level. The second shall be located as near the ceiling as practical, but in no case lower than the draft hood.

2) All Air from Outdoors (see Figure 3): An air supply shall be provided with one opening

that communicates directly with the outdoors by means of a duct. This duct shall be sized according to CSA B149.1 and terminate within one (1) foot (30.5 cm) above, and within two (2) feet (61 cm) horizontally from the burner level of the appliance having the largest input.

Requirements for Unconfined Spaces

An unconfined space is an area with at least fifty (50) cubic feet for each 1,000 Btuh (4.8 m/kW) of the total input rating for all gas appliances installed in that space. Water heaters installed in unconfined spaces do not usually require outdoor air to function properly. However, in buildings with tight construction (heavy insulation, vapour barriers, weather stripping, etc.), and particularly in modern buildings, additional fresh air may need to be provided. For instructions on obtaining additional air supply, see the requirements below for confined spaces.

Requirements for Confined Spaces

A confined space is an area where the volume is less then fifty (50) cubic feet for each 1,000 Btuh (4.8 m³/kW) of the total input rating for all gas appliances installed in that space. Water heaters installed in confined spaces require additional combustion and ventilation air. This can be provided in two ways:

When ducts are used, they shall be of the same cross-sectional area as the free area of the openings to which they connect. The minimum short side dimension of rectangular air ducts shall not be less than three (3) inches (7.62 cm).

Louvers and Grilles

In calculating free area for ventilation and combustion air supply openings, consideration must be given to the blocking effect of louvers, grilles, or screens protecting the openings. Screens must not be smaller than 1/4 inch (6.4 mm) mesh. If the free area through a particular design of louver or grille is known, it should be used in calculating the size of opening required to provide the free area specified. If the design and free area is unknown, it may be assumed that wood louvers and grilles will allow 20-25% free area and metal louvers and grilles will allow 60-75% free area. Louvers and grilles must be installed in the open position or interconnected with the water heater so that they are opened automatically during water heater operation.

Corrosive Atmospheres

If this water heater will be installed in a beauty shop, barber shop, photo processing lab, dry cleaning establishment, a building with an indoor pool, or near a chemical storage area, it is imperative that the combustion and ventilation air be drawn from outside these areas. These particular environments contain products such as aerosol sprays, detergents, bleaches, cleaning solvents, refrigerants, and other volatile compounds that, in addition to being highly flammable, become highly corrosive acid compounds when burned. Exposure to such compounds can be hazardous and lead to premature product failure.

Should the water heater fail due to exposure to such a corrosive atmosphere, the warranty is void.

INSTALLATION INSTRUCTIONS

Venting

When installing the venting system, make sure to follow all local codes or, in the absence of local codes, CSA B149.1 in Canada and/or the National Fuel Gas Code, ANSI Z223.1 in the United States. Never operate the water heater unless it is properly ventilated to the outdoors and has adequate air supply for proper operation. Failure to properly install the venting system could result in property damage, personal injury, or death.

Draft Hood installation

The water heater must be vented using the draft hood provided by the manufacturer. Before installing the draft hood, check to make sure that the flue baffle has been installed in the flue tube. If the flue baffle is missing, immediately contact the dealer where the water heater was purchased. Never operate the water heater without the flue baffle installed.

To install the draft hood, place it over the flue opening on the top of the water heater. When installing the draft hood do not alter it in any way.

UG30 and UG40 Models

Line up the holes in the draft hood’s legs with those of the water heater’s top and secure the draft hood using the two (2) sheet metal screws provided (see Figure 7a).

Figure 7a

Draft Hood

Venting System

The venting system must be attached to the draft hood to connect the water heater to the gas vent or chimney. The vent pipe connecting to the water heater must be of the same size as the draft hood. It is highly recommended to install this water heater on a separate venting system from other appliances. In some installations, proper venting may require the use of a larger diameter vent pipe and/or combined venting with other appliances. Consult the vent tables in the CSA B149.1 in Canada and/or the National Fuel Gas Code, ANSI Z223.1 in the United States to correctly size the vent pipe.

When connecting the vent pipe to the water heater the following instructions must be followed:

• Install the vent pipe in such a way as to avoid any unnecessary bends that could create resistance to the flow of combustion gases.

• The horizontal length of the vent pipe must not exceed 75% of the vertical vent height, in no case shall it exceed twenty (20) feet (6.1 m) horizontally.

• All horizontal runs must have a minimum rise of 1/4 inch per foot (21 mm/m) of run (See Figure 8).

• All joints must be securely fastened with sheet metal screws or other approved means.

• All single wall vent piping must maintain a minimum of six (6) inches (15.2 cm) of clearance from combustible materials.

• Venting systems made with single wall piping cannot pass through any attic, inside wall, crawlspace, confined space, or any floor.

• The vent piping must be accessible for inspection, cleaning, and replacement.

UG50 and UG60 Models

Line up the legs of the draft hood with the holes with those of the water heater’s top and snap into position. Then insert the two (2) sheet metal screws provided into the same holes to secure legs down into place

(see Figure 7b)

Figure 7b

Draft Hood

When the installation is complete, visually inspect the venting system to make sure that all joints are properly connected and all instructions have been followed. Failure to properly install the venting system could result in property damage, personal injury, or death.

Water Piping

Refer to Figure 8 for a typical installation. Use of this layout should provide a trouble-free installation for the life of the water heater. Before making the plumbing connections, locate the COLD water inlet and the HOT water outlet. These fittings are both 3/4” NPT male thread. Make sure that the dip tube is installed in the cold water inlet. Install a shut-off valve close to the water heater in the cold water line. It is recommended that unions be installed in the cold and hot water lines so that the water heater can be easily disconnected, if servicing is required.

INSTALLATION INSTRUCTIONS

When assembling the hot and cold piping to the water heater, use Teflon™ tape or a good food grade of pipe joint compound, and ensure all fittings are tight. It is imperative that open flame is not applied to the inlet and outlet fittings, as heat will damage or destroy the plastic lined fittings. This will result

in premature failure of the fittings, which is not covered by the warranty.

Temperature and Pressure-Relief Valve

DO NOT plug the temperature and pressure-relief valve or its discharge line. DO NOT remove the relief valve. Make sure the relief valve is properly sized for the water heater. If the relief valve continuously discharges water, call a qualified service technician to correct the problem. Failure to follow these instructions can result in property damage, personal injury, or death.

To protect from excessive pressure and/or temperature, the manufacturer has installed a temperature and pressure-relief valve that meets the requirements of the Standard for Relief Valves and Automatic Gas ShutOff Devices for Hot Water Supply Systems, CSA 4.4 in Canada and ANSI Z21.22 in the United States. This relief valve has a maximum set pressure that does not exceed the hydrostatic working pressure of the water heater (150 psi = 1,035 kPa) and a Btuh rating equal to or greater than the input rating, as shown on the water heater rating plate. It should never be plugged or removed from the opening marked for it on the water heater.

Should this relief valve need to be replaced, use only a new temperature and pressure-relief valve. Never install an old or existing relief valve as it may be damaged or inadequate for the working requirements of the new water heater. This new relief valve must meet all local codes or, at a minimum, the requirements listed above. Never install any other type of valve between the relief valve and the water heater.

INSTALLATION INSTRUCTIONS

A discharge line must be installed into the relief valve. The discharge line:

• Must not be smaller than the outlet pipe size of the relief valve.

• Must not terminate less than six (6) inches (15.2 cm) and not more than twelve (12) inches (30.5 cm) above a floor drain.

• Must not be restricted in any way. Do not thread, cap, or in any way restrict the end of this outlet.

• Must be of a material capable of withstanding 210°F (99°C) without distortion.

• Must be installed to allow complete drainage of the relief valve and discharge line.

• Must terminate at an adequate free-flowing drain.

Pressure Build-up in a Water System

When the water heater operates, the heated water expands creating a pressure build-up. This is a natural function and is one of the reasons for installing a temperature and pressure-relief valve. If the cold water supply line has a built-in water meter, check valve, or pressure-reducing valve, a suitable expansion tank must be installed to prevent pressure build-up or water hammer effect, otherwise the warranty is void (see Figure 8). An indication of pressure build-up is frequent discharges of water from the relief valve. If the relief valve discharges water on a continuous basis, it may indicate a malfunction of the relief valve, and a qualified service technician must be called to have the system checked, and the problem corrected.

Filling the Water Heater

4) Check all of the plumbing connections to make sure there are no leaks.

Gas Connections

DO NOT attempt to use this water heater with any gas other than the type of gas shown on the water heater rating plate. Failure to follow this instruction can result in property damage, personal injury, or death.

The gas piping must be installed as indicated in Figure 8. For the correct size of piping for this water heater, consult CSA B149.1 in Canada and/or the National Fuel Gas Code, ANSI Z223.1 in the United States. Only new piping with cleanly cut threads may be used, together with a suitable sealing compound that is approved for natural and propane gases. It is mandatory that a readily accessible manual shutoff valve be installed in the gas supply line. The gas supply manual shut-off valve must be close to the water heater. A drip leg (sediment trap) must be installed in the gas line ahead of the gas control to prevent dirt from entering it. A union must be installed between the gas control and the gas supply manual shut-off valve for easy maintenance of the water heater.

NEVER use an open flame to test for gas leaks. A fire or explosion could occur resulting in property damage, personal injury, or death.

NEVER operate the water heater unless it is completely filled with water. Failure to follow this

instruction can result in premature failure of the water heater that is not covered by the warranty.

Check that all of the water piping connections have been made. To fill the water heater:

1) Make sure that the water heater drain valve is closed by inserting a flat-head screwdriver into the slot on the head of the drain valve and turning the knob clockwise .

2) Open the cold water supply manual shut-off valve. This valve must remain open as long as the water heater is in use. Never operate the water heater with the cold water supply manual shut-off valve closed.

3) To make sure the water heater is completely full of water, open hot water faucets to let the air out of the water heater and plumbing system. Leave the faucets open until a constant flow of water is obtained.

The water heater and its gas connection must be leak tested before placing the appliance into operation. To leak test the system:

1) Turn on the manual gas shut-off valve near the water heater.

2) Use a soapy water solution to test all connections and fittings for leaks. Bubbles indicate a gas leak.

3) Correct all leaks.

Make sure that the inlet pressure to the water heater does not exceed fourteen (14) inches in W.C. (water column) for both natural and propane gases. Pressures in excess of 1/2 pound per square inch (3.5 kPa) can damage the gas control, resulting in a fire or explosion from leaking gas. For purposes of adjustment, the minimum inlet pressure is indicated on the water heater rating plate.

If any pressure testing of the gas line is undertaken at test pressures in excess of 1/2 psig (3.5 kPa), the water heater and its gas supply manual shut-off valve must be disconnected from the gas supply piping system,

INSTALLATION INSTRUCTIONS

and the end of the pipe sealed with a female cap. If the testing is to be undertaken at a test pressure less than 1/2 psig (3.5 kPa), the gas supply manual shut-off valve must be closed. For purposes of adjustement, the minimum inlet pressure should be one (1) inch water column above the operating manifold pressure. If manifold pressure is tested at the outlet pressure tap of

the gas control, results should show 4” w.c.

0,3” w.c..

A high altitude orifice MUST BE installed for water heaters operating above 2,000 feet (609.6 m) of altitude. Failure to follow this instruction can result in property damage, personal injury, or death.

Installation Instructions for Water Heaters Approved for Space Heating & Potable Water Heating

A water heater cannot be used for space heating only. When using a water heater for space and potable water heating, the instructions provided in this manual and with the air-handling unit must be respected and, in particular the following:

1) All piping and components that are used in the system must be of a nonferrous type suitable for potable water. This also applies to any sealant used.

2) When used as a dual purpose water heater, it must not be connected to any system that has been previously used for non potable water heating. This includes any piping because, in all probability, existing piping would have been, in the past, treated with chemicals for cleaning or sealing the system.

3) If this water heater is to be used for space heating, make sure that all safety codes are respected. Pay special attention to safety valve pressure and expansion tanks.

4) Do not use toxic chemicals to clean the potable water heating system.

5) Where water temperature in excess of 140°F (60°C) is required for a space heating application, a mixing valve must be installed in the potable side of the system. This will temper the water and reduce the risk of scalding.

6) If the incoming water line to the heater is equipped with a check valve, water meter, or pressurereducing valve, an expansion tank must be installed in the system. This will prevent weeping from the water heater relief valve and premature failure of the heater due to expansion of the water during the heating cycle.

7) Before acquisition of a water heater for space heating application, it is necessary to have the area of intended use sized by a qualified technician. This will ensure that an adequate water heating capacity will be available for both heating and potable water supply, and that the application will meet all local codes and public utility requirements.

Note: It is good practice to oversize the water heater, to ensure that all of the potential hot water requirements are available. Always refer to local plumbing codes for proper installation.

FOR YOUR SAFETY, READ BEFORE LIGHTING

LIGHTING INSTRUCTIONS

WARNING:

If you do not follow these instructions exactly,

a fire or explosion may result causing property damage, personal injury, or death.

A. This appliance has a pilot which must be lit by a piezo-electric spark gas ignition system. DO NOT open the inner door and attempt to light the pilot by hand. B. BEFORE LIGHTING, smell all around the appliance area for gas. Be sure to smell next to the floor because some gases are heavier than air and will settle on the floor.

WHAT TO DO IF YOU SMELL GAS:

- DO NOT try to light any appliance.

- DO NOT touch any electric switch.

- DO NOT use any phone in your building.

- From a neighbour's phone, immediately call your gas supplier. Follow the gas supplier's instructions.

- If you cannot reach your gas supplier, call the fire department. C. Use only your hand to push in or turn the gas control knob. Never use tools. If the knob will not push in or turn by hand, do not try to repair it. Call a qualified service technician. Force or attempted repair may result in a fire or explosion. D. DO NOT use this water heater if any part has been under water. Immediately call a qualified service technician to inspect the water heater and to replace any part of the control system and any gas control which has been under water.

Electrode

Lighting the Water Heater

Before lighting or re-lighting your water heater, make sure that you have read and understood all of the instructions and warnings in this manual and on your water heater. If you have any

questions about lighting your water heater, immediately contact a qualified installer, service agency, or the gas supplier.

DO NOT light this water heater if:

• It is not full of water.

• The gas supplied does not match the type listed on the rating plate.

• The sight glass or burner access door gasket has been damaged or broken.

• Gasoline or other flammable vapours and liquids have been stored in the vicinity of the water heater.

Failure to follow these instructions can result in property damage, personal injury, or death.

OPERATING INSTRUCTIONS

Draft Hood Operation

It is important to check that the ventilation system is working properly once the water heater main burner has been lit. Wait ten (10) minutes after lighting the burner. Then introduce a match or candle around the opening of the draft hood. If the flame is drawn towards the opening, this indicates proper ventilation. If the flame flutters or is blown out, combustion gases are escaping from the draft hood opening. If this occurs, shut the water heater off immediately and locate the problem. Do not try and operate the water heater again until you are satisfied that the problem has been corrected.

Water Temperature Regulation

The higher the setting, the greater the risk of scalding. Hot water can cause third degree burns in under one (1) second at 160°F (71°C), in five (5) seconds at 140°F (60

C) and in thirty (30) seconds at 130°F (54°C). In households where there are children, physically challenged individuals, or elderly persons, mixing valves for point of use are necessary as means of reducing the scalding potential of hot water.

The gas control is factory-adjusted to its lowest temperature. The desired water temperature can be selected by rotating the temperature dial on the front of the gas control. Turn the temperature dial clockwise to decrease the temperature, or counterclockwise to increase the temperature. The reference mark on the temperature dial, indicated by a large triangle, represents 130°F (54°C) (see Figure 9). Each mark to the left and right of this reference mark indicates a temperature change of approximately 10°F (6°C).

Figure 9

PUSH

When hot water is drawn from the tank in frequent short bursts, a condition known as “stacking” is created. “Stacking” is the result of increased cycling of the burner and can produce very hot water temperatures at the hot water outlet. Always remember to check the hot water coming out of any faucet with your hand before use. This will reduce the risk of scaldingrelated injury.

The gas control is equipped with a high limit switch (H.L.S.). Should the temperature of the water exceed 195°F (90°C), the H.L.S. will shut off the gas to the water heater. If the H.L.S. has tripped, the gas control must be replaced by a qualified service technician.

Should overheating occur or the gas supply fail to shut off, close the gas supply manual shut-off valve. Failure to follow this instruction can result in property damage, personal injury, or death.

If the water heater has been subjected to fire, flood, or been damaged in any way, close the gas supply manual shut-off valve. Do not operate the water heater again until it has been inspected by a qualified service technician.

2) Depress slightly and turn the gas control knob clockwise to the “OFF” position.

3) Once the gas supply has been re-established, proceed to the Lighting Instructions.

GENERAL MAINTENANCE

Housekeeping

DO NOT store or use gasoline or other flammable vapours and liquids around the water heater. DO NOT block or, in any way, restrict the flow of fresh air through the combustion air intake holes at the bottom of the water heater. DO NOT put or store any objects on the top of the water heater. Failure to follow these instructions can result in property damage, personal injury, or death.

Keep the area around the water heater clean and free of dust, lint, and dirt. Verify the combustion air intake holes, at the bottom of the water heater, at least once every six (6) months and vacuum up any dirt, as required. Make sure that all of the minimum clearances to combustible materials are being maintained.

Condensation

As moisture from the products of combustion comes into contact with the cold surface of the inner tank, it may condense. This situation will usually occur:

1) when the water heater is filled with cold water for the first time;

Main Burner & Pilot

Every three (3) months, check the main burner and pilot flame. Remove the outer access door and look through the sight glass to examine the flames. A soft blue flame indicates proper gas combustion. A yellow tipped flame indicates poor combustion. With a vacuum cleaner, remove any dust, lint, and dirt accumulation on or around the combustion chamber and in the combustion air intake holes.

DO NOT remove the inner access door at any time. If the combustion chamber must be accessed to clean the burner assembly or flame arrestor grille, a qualified service technician must be called. Failure to follow these instructions can result in property damage, personal injury, or death.

Temperature and Pressure-Relief Valve

Manually operate the temperature and pressure-relief valve at least once a year, standing clear of the outlet to avoid being burned. Lift and release the operating lever on the valve to make it operate freely. If, after manually operating the valve, it fails to completely reset itself and continues to discharge water, replace it with a new one.

2) if the water heater has been undersized;

3) when large amounts of hot water are drawn from the water heater in a short period of time and the refill water is very cold.

Due to the high-efficiency rating of this gas-fired water heater, it may produce more condensation than older models. Condensation forming on the flue tube will drop on the burner making a “sizzling” sound. In extreme cases, the condensate may even extinguish the pilot flame. This condition is not uncommon and must never be misinterpreted as a leaking tank. It will disappear once the water becomes heated.

Because of the large amounts of water that can condense, it is very important that a drain pan be installed under the water heater (refer to the Location

section of this manual). Under no circumstances is the manufacturer to be held liable for any water damage, in connection with this water heater.

If the problem does not go away and water continues to drip after the water heater has heated up, check all of the plumbing connections to make sure they are not leaking.

Venting System Inspection

The venting system must be thoroughly inspected once a year. Check the area where the water heater is located to make sure that there is enough clean combustion and ventilation air. Remove any possible obstructions that would prevent proper air circulation and venting. Check the venting system to make sure that all of the connections are securely fastened, and that all of the joints are properly sealed. If any part of the venting system is damaged, it must be replaced by a qualified service technician. Test the ventilation system to make sure that it is venting properly

(refer to the Draft Hood Operation section of this manual).

Anode

This water heater is equipped with an anode that is designed to prolong the life of the glass-lined tank. The anode is slowly consumed, protecting the glass-lined tank from corrosion. The anode should be checked every two (2) years. If more than half of the anode has been consumed it should be replaced. Instructions on how to change the anode can be obtained from the manufacturer.

GENERAL MAINTENANCE

The life expectancy of the water heater is reduced where a water softener is introduced to fight hard water, because the sodium salts added by a softener make this water extremely conductive. In these conditions, the anode is consumed more rapidly and should be verified every year.

In certain water conditions, the anode will react with the water, producing discoloured or smelly water. The most common complaint is hot water that smells like rotten eggs. This phenomenon is the result of the reaction between the anode and hydrogen sulfide gas dissolved in the water which occurs frequently in well systems. This problem can usually be eliminated or reduced by changing the anode to a type more suitable for these conditions (aluminum anode) and by chlorinating the water heater and plumbing system. If the problem persists, special filtration equipment may be required. Under no circumstances is the anode to be removed from the water heater on a permanent basis. Removal of the anode will lead to premature

failure of the water heater and void the warranty.

6) Open the drain valve by inserting a flat-head screwdriver into the slot on the head of the drain valve and turning the knob counterclockwise .

7) Open a hot water faucet to allow air into the system.

Vacation

If you are planning a vacation or other prolonged absence, it is highly recommended to shut off the gas supply and the cold water supply to the water heater. This will save energy, protect against property damage in the event the water heater leaks, and prevent the build-up of hydrogen gas. If the water heater and piping are exposed to freezing temperatures, they should both be drained.

Remember to check the water heater thoroughly after it has been shut off for an extended period of time before putting it back in operation. Make sure that the water heater is completely full of water and that the cold water supply manual shut-off valve is open before lighting the burner.

Hydrogen gas can be produced in a hot water system that has not been used for a long period of time (generally two (2) weeks or more). HYDROGEN GAS IS EXTREMELY FLAMMABLE. It is highly recommended to open the hot water faucet in the kitchen for several minutes before you use any electrical appliances connected to the hot water system, such as a dishwasher or washing machine. If hydrogen gas is present, there will be an unusual sound, such as air escaping through the pipe, as the hot water faucet is opened. DO NOT smoke or introduce an open flame near the faucet when it is opened.

Draining the Water Heater

Drain a pail of water through the drain valve at least once a year. This will remove excess sediment from the bottom of the tank. This sediment, if allowed to accumulate, will reduce the efficiency and the life of the tank.

To completely drain the water heater:

1) Turn the temperature dial clockwise to the “Pilot Lighting” position.

2) Depress slightly and turn the gas control knob clockwise to the “OFF” position.

3) Close the gas supply manual shut-off valve.

4) Close the cold water supply manual shut-off valve.

5) Connect one end of a garden hose to the water heater drain valve and put the other next to a freeflowing drain.
