Safety Warning (Flammable Vapours)

WARNING

DANGER

Carbon Monoxide Warning

• Follow all vent system requirements by

the local authorities having jurisdiction

over your installation.

FLAMMABLES

Flammable Vapours

• Failure to do so can result in death, explo-

sion or carbon monoxide poisoning.

FIRE AND EXPLOSION HAZARD

Can result in serious injury or death

Do not store or use gasoline or other flammable vapours and liquids

in the vicinity of this or any other appliance. Storage of or use of gasoline

or other flammable vapours or liquids in the vicinity of this or any other

appliance can result in serious injury or death.

Relief Valves (T&P)

All water heaters must be installed with a proper tempera-

ture and pressure relief valve. These valves must be certi-

fied as meeting the requirements of the “Standard for

Temperature, Pressure, Temperature and Pressure

Relief and Vacuum Relief” CSA 4.4 in Canada. In the

United States “Relief Valves and Automatic Gas Shut-Off

Devices for Hot Water Supply Systems”, ANSI Z21.22 is

applicable.

There is a risk in using fuel-burning appliances such as

water heaters. Areas that may not be suitable for water

heater installation include those where flammable liquids,

gasoline, solvents, adhesives, etc., or engine-driven equip-

ment or vehicles are stored, operated or repaired. Due to

the nature of air movement, flammable vapors can be car-

ried some distance from the point of storage. The gas-fired

water heater igniter or main burner flame can ignite these

vapors causing a flashback, fire or explosion which may

result in serious personal injury or death, as well as severe

property damage.

If this water heater has been exposed to flooding, freezing,

fire or any unusual condition, do not put it into operation until

it has been inspected and approved by a qualified profes-

sional. THESE CONDITIONS CAN RESULT IN UNSEEN

INTERNAL DAMAGE which is not subject to warranty cov-

erage.

Safety Warning (Scalding)

Backflow Prevention

DANGER

Certain jurisdictions may require the installation of a back-

flow device (e.g., check valve) in the water supply line. Such

a device will require the use of a system expansion tank of

adequate size to control the thermal expansion generated

during the heating cycle. Consult your water supplier or

local plumbing authority.

Important: The supply water meter may have a built-in

check valve device. Contact your local water authority.

Hot water produced by this appliance can cause severe

burns due to scalding. The hazard is increased for young

children, the aged or the disabled where water tempera-

tures exceed 52°C (125°F). Use tempering valves (see

Figure 11), in the hot water system to reduce the risk of

scalding at point-of-use such as lavatories, sinks and

bathing facilities. Such precautions must be followed when

this heater is operated in combination with dishwashing or

space heating applications.

CAUTION

Hydrogen gas can be produced in a hot water system

served by this heater that has not been used for a long

period of time (generally two (2) weeks or more).

Hydrogen gas is extremely flammable and can ignite

when exposed to a spark or flame. 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 con-

nected to the hot water system. Use caution in opening

faucets. If 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.

Safety Warning (Carbon Monoxide)

As with all fuel burning equipment, this heater requires an

adequate supply of air for combustion and ventilation. An

insufficient air supply can result in poor combustion or the

re-circulation of the exhaust flue gases. Such a condition

This water heater must be installed strictly in accordance

with the instructions enclosed, and local electrical, fuel

and building codes. It is possible that connections to the

water heater, or the water heater itself, may develop

leaks. IT IS THEREFORE IMPERATIVE that the water

heater be installed so that any leakage of the tank or relat-

ed water piping is directed to an adequate drain in such a

manner that it cannot damage the building, furniture, floor

covering, adjacent areas, lower floors of the structure or

other property subject to water damage. This is particular-

ly important if the water heater is installed in a multi-story

building, on finished flooring or carpeted surfaces. GSW

WILL NOT ASSUME ANY LIABILITY for damage caused

by water leaking from the water heater, pressure relief

valve, or related fittings. Select a location as centralized

within the piping system as possible. In any location

selected, it is recommended that a suitable drain pan be

installed under the water heater. This pan must limit the

water level to a MAXIMUM depth of 45mm (1 3/4 in.) and

have a diameter that is a minimum of 50mm (2 in.) greater

than the diameter of the water heater. Suitable piping shall

connect the drain pan to a properly operating floor drain.

When used with a fuel-fired heater, this drain pan must not

restrict combustion air flow.

Install the gas piping as shown in Figure 4. Use only new

pipe and fittings with clean-cut threads. Sealing compounds

used on the pipe threads shall be approved for use with nat-

ural and propane gas.

Use gas piping of adequate sizing to ensure gas input. Gas

piping material must be approved for use with natural gas

and propane fuels. All piping must comply with all local

codes or, in the absence of such codes, with the latest edi-

tion of “Natural Gas and Propane Installation Code”

CAN/CSA-B149.1 in Canada, “National Fuel Gas Code”

ANSI Z223.1 (NFPA 54) in the U.S.A. The final connection

to the water heater is made using 1/2” NPT.

WARNING

Do not install directly on carpet. Instead, place the

water heater on a metal or wood panel extending a

minimum of 75mm (3 in.) from all sides. In alcoves or

closets, cover the carpet completely. Ensure this

panel is capable of supporting the weight of this

heater when filled with water.

FAILURE TO PROPERLY INSTALL THIS HEATER MAY

RESULT IN A FIRE HAZARD.

The water heater shall be located in an area not subject to

freezing temperatures. Water heaters located in uncondi-

tioned spaces (e.g., attics, basements, etc.) may require

insulation of the water and drain piping to protect against

freezing. Proper ventilation needs to be provided for water

heaters installed in unconditioned spaces (e.g., attics, base-

ments, etc.) in order to avoid an event where air tempera-

ture exceeds 42°C (108°F). The drain and controls must be

easily accessible for operation and service. Maintain proper

clearances as specified on the data plate.

Before connecting to the gas service, check that a properly

sized gas meter and regulator are available to service the

water heater. If other appliances are using the same meter

and regulator, ensure that the capacity of the meter and reg-

ulator matches that of the combined input of all appliances

connected to it.

DO NOT tamper with the gas control/thermostat, igniter,

thermocouple, or temperature and pressure relief valve.

Tampering voids all warranties. Only a qualified service

technician should service these components.

Ensure that the water heater is level. This heater may be

installed in a closet or alcove and is certified for operation

on a combustible floor.

Do not locate the water heater near an air-moving device.

Gas Pressure

WARNING

Exposure to a higher gas supply pressure

may cause damage to the control, resulting

in explosion or fire. Consult your local gas

supplier and gas authorities. DO NOT PUT

INTO SERVICE IF OVER-PRESSURIZATION

HAS OCCURRED.

GSW Water Heating Company recommends that the gas

supply pressure, as measured on the inlet side of the water

heater control, be set at 7.0 in. w.c.(1.7 kPa) for natural gas

and 11.0 in. w.c. (2.7 kPa) for propane gas. The above pres-

sures must be measured during water heater operation. The

gas control supplied with this water heater is designed for a

maximum inlet pressure of 0.5 psi (14 in. w.c.). Do not

exceed 0.5 psi (14 in. w.c.). The Flame Guard^TMsafety sys-

tem is designed to operate at a manifold pressure of 5.0 in.

w.c. (1.2 kPa) for natural gas and 10.0 in. w.c. (2.4 kPa) for

propane gas.

Gas line purging

Gas line purging is required to eliminate air from the piping

system. Purging should be performed by persons experi-

enced in this type of gas service in compliance with the

code having jurisdiction. Do not purge in confined areas or

space where ignition may occur. To avoid risk of fire or

explosion ensure the area is well ventilated and all sources

of ignition are de-activated. Contact your local gas authority

for local requirements.

Gas Leak Testing

Important: This water heater and its gas connection must

be tested for leaks before placing the appliance in opera-

tion. Perform a leak test at normal gas pressure. If the appli-

cable code(s) require the gas lines to be tested at a pres-

sure of 14 in. w.c. (3.5 kPa) or greater, the water heater and

its manual shut-off valve must be disconnected from the gas

supply piping system and the line capped. Test all connec-

tions of the gas system with a chloride-free soap and water

solution or equivalent leak test liquid. Bubbles will indicate

leaks. Never use a match or open flame to test for gas

leaks. A fire or explosion could result. If leaks exist repair as

required and retest.

DO NOT light the burner before the tank is filled with water

and you have confirmed that there are no leaks in the pip-

ing and connections.

Air Requirements

(a)

Important: Air for combustion and ventilation must not

come from a corrosive atmosphere. Any failure due to cor-

rosive elements in the atmosphere is excluded from war-

ranty coverage.

Installations in or for certain places including, but not limited

to, those listed below will require outdoor air for combustion

due to chemical exposure:

Water heaters installed near chemical storage areas

EQUIPMENT LOCATED IN CONFINED SPACES;

ALL AIR FROM INSIDE THE BUILDING.

In such circumstances, outdoor combustion air may reduce,

but will not eliminate, the presence of corrosive chemicals in

the air. Combustion air must be free of acid-forming chemi-

cals such as sulfur, fluorine and chlorine. These elements

are found in aerosol sprays, detergents, bleaches, cleaning

solvents, air fresheners, paint and varnish removers, refrig-

erants and many other commercial and household prod-

ucts. When burned, vapors from these products form highly

corrosive acid compounds. These products should not be

stored or used near the water heater or air inlet.

should not exceed 550 kPa (80psi). If this occurs a pressure

reducing valve and/or an expansion tank may be required.

The pressure reducing valve should be placed on the sup-

ply to the entire house in order to maintain equal hot and

cold water pressures.

Important: Heat must not be applied to the water fittings on

the heater as they may contain nonmetallic parts. If solder

connections are used, solder the pipe to the adapter before

attaching the adapter to the hot and cold water fittings.

Install the water piping and fittings as shown in Figure 10.

Connect the cold water supply to the fitting (3/4” NPT)

marked “COLD” (or “C”). Connect the hot water supply to

the fitting (3/4” NPT) marked “HOT” (or “H”).

The vent pipe must be installed in accordance with all local

and provincial or state codes or, in the absence of such

codes, with the latest edition of “Natural Gas and Propane

Installation Code” CAN/CSA-B149.1 in Canada,

“National Fuel Gas Code” ANSI Z223.1 (NFPA 54) in the

U.S.A. The vent pipe must not be obstructed so as to pre-

vent the removal of exhaust gases to the outside atmos-

phere.

Note: The horizontal section of the vent must slope up

21mm per metre (1/4 in. per foot), (see Figure 8).

U.L. recognized fuel gas and carbon monoxide (CO) detec-

tors are recommended in all applications and should be

installed using the manufacturer’s instructions and local

codes, rules or regulations.

Important: If you lack the necessary skills required to prop-

erly install this venting system, you should not proceed, but

enlist the help of a qualified service technician.

for potable water on the cold water supply line. The

expansion tank must have a minimum capacity of 5.7

litres (1.5 US gallons) for every 190 litres (50 US gal-

lons) of stored water and be rated for 150 psi or the

working pressure of the water heater.

2. Install a pressure relief valve rated at max 125 psi in the

cold water supply line. Make sure the discharge of this

valve is directed to an open drain and protected from

freezing. Contact the local water supplier or plumbing

inspector for information on how to control this situation.

Figure 11 Typical Tempering Valve Installation

Important: Always use a good grade of joint compound,

approved for use with potable water systems, and be certain

that all fittings are drawn up tight.

• Do not plug valve.

Important: Some models may contain energy saving heat

traps to prevent the circulation of hot water within the pipes.

Do not remove, modify or tamper with the heat traps or any

inserts within the heat traps.

• Do not remove valve.

• Failure to follow these instructions can

result in death or an explosion.

Refer to Figure 12 for a typical T&P valve installation.

Important: Only a new temperature and pressure relief

valve should be used with your water heater. Do not use an

old or existing valve as it may be damaged or not adequate

for the working pressure of the new water heater. Do not

place any valve between the relief valve and the tank.

Please note the following:

DO NOT install this water heater with iron piping. The sys-

tem should be installed only with new piping that is suitable

for potable (drinkable) water such as copper, CPVC or poly-

butylene. DO NOT use PVC water piping.

DO NOT use any pumps, valves or fittings that are not com-

patible with potable water.

DO NOT use valves that may cause excessive restriction to

water flow. Use full flow ball or gate valves only.

DO NOT use any lead based solder in potable water lines.

Use appropriate tin-antimony or other equivalent material.

DO NOT use with piping that has been treated with chro-

mates, boiler seal or other chemicals.

Closed System/Thermal Expansion

DISCHARGE LINE 19mm (3/4 in.)

MIN. DO NOT CAP OR PLUG.

Periodic discharge from the temperature and pressure relief

valve may be due to thermal expansion in a closed water

supply system. The water utility supply meter may contain a

check valve. This will create a closed water system. During

the heating cycle of the water heater, the water expands

causing pressure inside the water heater to increase. This

may cause the temperature and pressure relief valve to dis-

charge small quantities of hot water. To prevent this from

happening, there are two recommendations:

Temperature Adjustment

IV) OPERATING INSTRUCTIONS

Water Temperature Regulation

The thermostat of this water heater has been factory set at

its lowest position. It is adjustable and must be set to the

desired temperature setting. The preferred starting point is

49°C (120°F). Turn the water temperature dial clockwise

HOT WATER CAN SCALD: Water heaters are intended to

produce hot water. Water heated to a temperature that will

satisfy space heating, clothes washing, dish washing, and

other sanitizing needs can scald and permanently injure you

upon contact. Some people are more likely to be perma-

nently injured by hot water than others. These include the

elderly, children, the infirm, or physically/mentally handi-

capped. If anyone using hot water in your home fits into one

of these groups or if there is a provincial, state law or local

code requiring a specific hot water temperature at the tap,

then you must take special precautions. Never allow small

children to use a hot water tap, or to draw their own bath

water. Never leave a child or handicapped person unat-

tended in a bathtub or shower.

to decrease the temperature, or counterclockwise

increase the temperature.

Figures 13a & 13b show the approximate water tempera-

tures produced at various thermostat settings. Short repeat-

ed heating cycles caused by small hot water uses can

cause temperatures at the point-of-use to exceed the ther-

mostat setting by up to 17°C (30°F). If you experience this

type of use you should consider using lower temperature

settings to reduce scald hazards. Should overheating occur

or the gas supply fail to shut off, turn off the manual gas con-

trol valve to the appliance.

DANGER

Valves for reducing the point-of-use temperature by mixing

cold and hot water are available (see Figure 2). Also avail-

able are inexpensive devices that attach to faucets to limit

hot water temperatures. Contact a licensed plumber or the

local plumbing authority.

Note: During low demand periods, a lower thermostat set-

ting will reduce energy losses and may satisfy your normal

hot water needs. If hot water use is expected to be more

than normal, a higher thermostat setting may be required to

meet the increased demand. When leaving your home for

extended periods (e.g., vacations etc.) turn the temperature

dial to its lowest setting. This will maintain the water at low

temperatures with minimum energy losses and prevent the

tank from freezing during cold weather.

Water temperature over 52°C (125°F) can cause

severe burns instantly or death from scalds.

Children, disabled and elderly are at highest risk of

being scalded.

It is recommended that lower water temperatures be used

to avoid the risk of scalding. It is further recommended, in all

cases, that the water temperature be set for the lowest tem-

provide the most energy efficient operation of the water

heater.

and if the water heater is not allowed enough time to reach

the room temperature, the pilot burner might be extin-

guished in the first 20 minutes from start-up due to heavy

condensation. In this situation if the unit is relit, it will follow

its normal heating cycle without further incidents. After

installation always allow the water heater to reach the room

temperature before the initial start-up is initiated. Supervise

the flame inside the water heater at least 20 minutes at ini-

tial start-up to ensure that heavy condensation is not turning

off the water heater.

V) OPERATION

Burner Flames

Inspect the burner flames through the viewport and com-

pare them to the drawings in Figure 14. A properly operat-

ing burner should produce a soft blue flame. Blue tips with

yellow inner cones are satisfactory. The tips of the flame

may have a slight yellow tint. The flame should not be all

yellow or have a sharp blue-orange color. Contaminated air

may cause an orange colored flame. Contact a qualified

service technician if the flame is not satisfactory.

Emergency Shut Down

Important: Should overheating occur or the gas supply fail

to shut off, turn off the water heater’s manual gas shut-off

valve and call a qualified service technician.

Safety Shut-off

This water heater is designed to automatically shut-off in the

event of the following:

Checking the Draft

After successfully lighting the water heater, allow the unit to

operate for 15 minutes and check the drafthood relief open-

ing for proper draft. Pass a match flame around the relief

opening of the drafthood as shown in Figure 15. A steady

flame drawn into the opening indicates proper draft. If the

flame flutters or is blown out, combustion products are

escaping from the relief opening. If this occurs, do not oper-

ate the water heater until proper adjustments or repairs are

made to the vent pipe system.

•

The pilot flame is extinguished for any reason.

The water temperature exceeds 93°C (200°F).

Excessive combustion chamber temperatures.

The ignition of flammable vapors.

A thermocouple is used to determine if a pilot flame is pres-

ent and will shut off the gas supply to the main burner and

the pilot burner if the flame is absent.

A dual safety switch is part of the water heater safety sys-

tem. The gas control is connected to a door-mount manual

ly resettable safety switch which is designed to disable the

gas control/thermostat in the event of excessive combustion

chamber temperatures or a flammable vapor incident. If the

thermal switch opens, the water heater cannot be used

unless this thermal switch is reset by a qualified service

technician.

R E L I E F

OPENING

MATCH

The gas control has a high temperature limit switch or ECO

(Energy Cut Off) which is used to shut off the unit if the

water temperature exceeds 93°C (200°F). The ECO is a

single use switch and requires complete replacement of the

entire gas control/thermostat. If the ECO should function,

the water heater cannot be used until the gas control/ther-

mostat is replaced by a qualified service technician. Contact

your local dealer for service information.

Figure 15 Checking The Draft

Operating Conditions

Condensation

Moisture from the products of combustion condenses on the

tank surface and forms drops of water which may fall onto

the burner or other hot surfaces. This will produce a “siz-

zling” or “frying” noise. This condensation is normal and

should not be confused with a leaking tank. Condensation

may increase or decrease at different times of the year.

Highly efficient energy saver water heaters will produce

larger amounts of condensation on initial start up or when a

large amount of hot water is being used. Once the water

reaches a temperature of 49°C (120°F) and the tank warms

up (usually about 1 hour), the condensation will stop.

Anode/Water Odour

Each water heater contains at least one anode, which will

slowly deplete while protecting the glass-lined tank prolong-

ing the life of the water heater. Certain water conditions may

cause a reaction between the anode and the water. The

most common complaint associated with the anode is a “rot-

ten egg smell” produced by the presence of sulfur. Do not

remove this anode permanently as it will void any war-

ranties, stated or implied. An aluminum anode may reduce

if not eliminate water odour problems. The water supply sys-

tem may require special filtration equipment from a water

conditioning company to successfully eliminate all water

odour problems.

Artificially softened water is exceedingly corrosive because

the process substitutes sodium ions for magnesium and cal-

cium ions. The use of a water softener may decrease the life

of the water heater tank. The anode should be inspected

periodically. If the anode is more than 50% depleted, the

anode should be replaced.

VI) MAINTENANCE

Draining and Flushing

It is recommended that the tank be drained and flushed

every 6 months to remove sediment which may buildup dur-

ing operation. The water heater should be drained if being

shut down for extended periods of time. To drain the tank,

perform the following steps:

1. Turn off the gas to the water heater with the manual gas

shut-off valve.

2. Close the cold water inlet valve.

3. Open a nearby hot water faucet.

4. Connect a hose to the drain valve and terminate it to an

adequate drain.

Note: The drain hose should be rated for at least 94°C

(200°F). If the drain hose does not have this rating, open the

cold water inlet valve and nearby hot faucet until the water

is no longer hot.

5. Open the water heater drain valve and allow all the

water to drain from the tank. Flush the tank with water

as needed to remove sediment.

6. Close the drain valve, refill the tank, and restart the

heater as directed under “Operating Instructions”. If the

water heater is going to be shut down for an extended

period, the drain valve should be left open.

Important: Condensation may occur when refilling tank and

should not be confused with a tank leak.

The installation and maintenance of the water heater must

comply with all of the instructions described in sections I to

IX of this manual. Water heater failure that is a result of the

heating system is not covered by warranty.

The following maintenance procedures are for the Flame

Guard^TMsafety system components and should be per-

formed by a qualified service technician.

Replacement parts (see Figures 20 & 21) may be ordered

through your local distributor. When ordering replacement

parts, always have the following information ready:

1. Model, serial and product number.

2. Type of gas.

3. Item number.

4. Parts description.

Periodic Inspection

Periodically a visual inspection should be made of the vent-

ing and air supply system, piping systems, main burner,

pilot burner and flame arrester.

Check the water heater for the following:

1. Obstructions, damage or deterioration in the venting

system. Make sure the ventilation and combustion air

supplies are not obstructed.

2. Build-up of soot and carbon on the main burner and

pilot burner. Check for a soft blue flame.

3. Leaking or damaged water and gas piping.

4. Presence of flammable or corrosive materials in the

installation area.

5. Presence of combustible materials near the water

heater.

6. Presence of debris on the outside of the flame arrester.

Temperature and Pressure Relief Valve

Manually operate the temperature and pressure relief valve

at least once a year to make sure it is working properly. To

prevent water damage, the valve must be properly connect-

ed to a discharge line which terminates at an adequate

drain. Standing clear of the outlet (discharged water may be

hot), slowly lift and release the lever handle on the temper-

ature and pressure relief valve (see Figure 18) to allow the

valve to operate freely and return to its closed position. If the

valve fails to completely reset and continues to release

water, immediately shut off the manual gas shut-off valve

and the cold water inlet and call a qualified service techni-

cian.

4. If the space heating water system requires water with

temperatures in excess of 60°C (140°F), a mixing valve,

or other means to temper the water and reduce scald

hazard potential, must be installed in the potable hot

water supply.

5. If the heater is installed with a back-flow preventer on

the incoming water line or in a closed system, a

diaphragm-type expansion tank must always be

installed in the system to prevent the T&P from relieving

due to thermal expansion.

6. Proper sizing of the water heater for the given space

and potable heating application is essential to ensure

adequate heating capacity. The sizing and installation of

such combination system must be performed by quali-

fied personnel and be in accordance with public utility

requirements and/or codes having jurisdiction.

VII) COMBO HEATING

This section serves as a guide for the installation and use of

“Combo” heating systems utilizing a domestic water heater

which has been specifically approved for such use (see

Figure 19). It is written for those knowledgeable in the

required trades and professionals involved in the design

and installation of Combo Heating Systems.

It is the responsibility of the installer/designer to follow all

applicable codes to ensure the effectiveness and safety of

the installation.

System Requirements

The following requirements must be met for the installation

of Combo Heating Systems:

1. The piping and components connected to the water

heater for the space heating applications shall be suit-

able for use with potable water. The system should be

installed with new, non-ferrous piping. Do not use

pumps, valves, fittings, solder, gluing and pipe sealant

that are not completely compatible with potable water

piping.

2. A water heater which will be used to supply potable

water must not be connected to any heating system or

components previously used with a non-potable water

heating appliance. Do not use piping that has been

treated with chromates, broiler seal or other chemicals

and do not add chemicals to the water heating piping.

Do not introduce toxic chemicals, such as those used

for boiler treatment, into the potable water used for

space heating.

The sizing of the water heater should be based on the

design heat loss of the structure to be heated plus the

potable water requirements.

IT IS IMPORTANT THAT THE WATER HEATER USED BE

OVERSIZED TO ALLOW ADEQUATE HEATING AND

POTABLE WATER HEATING CAPACITY.

3. Do not use this heater as a replacement for an existing

boiler installation.
