ly airtight so that there is not sufficient air for both combus-

tion and venting the products of combustion of an oil-fired

appliance, or for replacing the air vented by other exhaust

devices within the house.

Air Requirements

An adequate supply of combustion and ventilation air is

required to:

•

Ensure proper combustion.

Reduce risk of property damage, severe bodily injury or

death from possible flue gas leakage and carbon

monoxide emissions.

Outdoor Combustion & Ventilation Air

(Unconfined space)

Do not install an exhaust fan in the same room as the water

heater.

Satisfactory combustion cannot be sustained in an area that

is not provided with fresh air. Fresh air contains oxygen that

is necessary for proper combustion. If the water heater is

installed in a confined space, sufficient fresh air must be

drawn in from outside of the enclosure.

If the water heater is installed in an unconfined space in a

building having insufficient infiltration, additional air for com-

bustion and ventilation shall be obtained from outdoors or

from spaces freely communicating with the outdoors. Under

these conditions, permanent opening(s) shall be provided so

that the total air received through these openings will be at

least as much as would be admitted by openings having a

input rating of all oil-fired appliances.

Air Supply

CAUTION

Outdoor Combustion & Ventilation Air

(Confined space)

IF AN ALL-HOUSE VENTILATION FAN IS USED, A

SEPARATE OUTSIDE AIR DUCT MUST BE USED AND

DUCTED TO THE FURNACE ROOM AND/OR ROOM

WHERE THE WATER HEATER IS LOCATED.

A heater installed in a confined space that obtains all of its

air for combustion and ventilation from outside the building

shall be provided with two permanent openings, one near

the top of the enclosure and another near the bottom. Each

opening shall communicate directly or by means of ducts

with the outdoors or to such spaces (such as a crawl space)

that freely communicate with the outdoors, and shall be

sized in accordance with “Air Duct Sizing”.

In Canada:

If the water heater is installed in a house built to the require-

ments of the “National Building Code of Canada, 1985”,

or a subsequent edition, the space shall be provided with a

air inlets as outlined below, or have a mechanical air-supply

system of sufficient equivalent capacity. If a mechanical air-

supply system is used, it shall be interlocked to the appli-

ance or equipment.

NOTE: In unconfined spaces in buildings of conventional

frame, brick, or stone construction built prior to the require-

ments of the “National Building Code of Canada, 1985”,

and not subsequently significantly air-tightened, infiltration is

normally adequate to provide air for combustion and some

ventilation; however, there may be notable exceptions.

Houses built in accordance with the “National Building

Code of Canada, 1985” (or subsequent edition), with exten-

Outdoor Combustion Air & Indoor Ventilation

Air (Confined space)

An appliance located in a confined space that obtains its

combustion air from outdoors and ventilation air from within

the conditioned space of the building shall be provided with

two permanent openings for ventilation. One located near

the top of the enclosure and another near the bottom. Each

opening shall have a free area of not less than 19.5

•

Clean the chimney, including removal of blockage.

Repair or replace damaged pipe or liner.

Repair mortar and joints.

To prevent downdrafts, extend the chimney at least 1m (3 ft.)

above highest point where it passes through roof and

610mm (24 in.) higher than any portion of building within 3m

(10 ft.). Increase chimney cross-sectional area and height at

least 4% per 305m (1,000 ft.) above sea level.

Indoor Combustion & Ventilation Air

(Confined space)

A heater installed in a confined space and that obtains all of

its air for combustion and ventilation from within the condi-

tioned space of the building shall be provided with two per-

manent openings, one near the top of the enclosure and

another near the bottom. Each opening shall have a free

not suitable for this application. Flue temperatures may

exceed 300°C (572°F). Use flue piping approved for this

installation.

area of not less than 19.5 cm /kWh (1 in /1000 Btu/h) of the

total input rating of all appliances in the enclosure, freely

communicating with interior areas that have in turn adequate

infiltration from the outside.

Long horizontal flue pipes, excessive number of tees and

elbows or other obstructions restrict flue gas flow, and can

result in the possibility of condensation, flue gas leakage

and carbon monoxide emissions. These conditions can lead

to serious property damage, severe bodily injury or death.

The flue pipe should be the same size as the breech con-

nection on the appliance. The sizes generally are 150mm (6

in.) for burners rated less than 1.00 GPH and 178mm (7 in.)

for burners rated for 1.00 to 1.50 GPH. The flue pipe should

be as short as possible and installed so that it has a contin-

uous rise of 20mm/m (1/4 in./ft.) of horizontal length from the

breech connection on the appliance to the chimney. Elbows

should be minimized and the sections of pipe and fittings

should be joined with sheet metal screws and straps.

Routing should be made in such a way as to avoid sharp

Air Duct Sizing

The air duct requirements shall be met by one of the follow-

ing methods:

1. vertical duct(s) with a free area of not less than 5.5

cm /kWh (1 in /4000 Btu/h) of the total input rating of all

appliances in the enclosure;

2. horizontal duct(s), with an equivalent length of less than

15 m (50 ft), having a free area of not less than 11

cm /kWh (1 in /2000 Btu/h) of the total input of all appli-

ances in the enclosure; and

3. air openings that communicate directly with the outdoors,

having a free area of not less than 5.5 cm /kWh (1

Vent and Exhaust Connections

Draft Regulator

This device is used on conventional chimney venting only. It

automatically maintains a constant negative pressure in the

chimney to obtain maximum efficiency. If the chimney does

not develop sufficient draft, the draft control cannot function

properly. The heater must be equipped with an approved

draft regulator of adequate size. Make sure that the draft

regulator diameter is at least as large as the flue pipe diam-

eter. Follow manufacturers recommended instructions for

installation. It must be installed in the flue pipe before it

enters the chimney and after the Blocked Vent Safety

Switch, if one is used. Set the draft regulator at -0.03 in. (-

0.762mm) of water column, as measured in the flue

(between the heater and the draft regulator). Recommended

over-fire draft is -0.02 in. (-0.5078mm) of water column.

General chimney requirements

For a burner designed for natural draft connect the vent to a

vertical chimney. Insufficient draft can cause flue gas leak-

age and carbon monoxide emissions, which can lead to

severe bodily injury or death. Use vent material approved by

local codes for oil-fired burners. In the absence of such

codes, refer to:

•

Water Supply Connections

Pipes and fittings should be installed in as shown in the

installation drawing (Figures 7 & 8). Install a shut-off valve in

the cold water supply line in close proximity to the cold inlet

of the water heater. This valve is for use only when servic-

ing the heater and must be kept open during the heater’s

operation. The water connection fittings (nipples) may con-

tain a non-metallic lining to minimize corrosion and some

models include non-metallic heat traps. These appear like

pink or blue coloured plugs in the fitting. Do not attempt to

pry these plugs loose or damage them. DO NOT APPLY

HEAT DIRECTLY TO THE WATER HEATER NIPPLES. If

copper piping is used, solder a piece of tubing to a threaded

adaptor before screwing the adaptor to the nipples. Use only

solder approved for use with potable water systems. Use a

good grade of pipe joint compound, certified for use with

potable water, on the threaded fittings. Be sure all fittings are

drawn up tight.

NOTE: Rear and Combination flue units must be fitted with

a T&P Relief Valve WATTS type 40XL-5 or equivalent.

Failure to install and maintain a new, properly listed

temperature and pressure relief valve will release the

manufacturer from any claims which may result from

excessive temperature or water pressure.

Closed Water Systems

During the heating cycle of the water heater the water

expands creating a pressure build-up in the water system.

The water supply meter may contain a check valve or back

flow preventer. This will create a closed water system. A

Temperature and Pressure (T&P) Relief Valve (150 psi

Water Temperature Regulation

WARNING

Once installed, the operation will be completely automatic.

The thermostat (aquastat) on the water heater is adjustable

and will maintain water at the desired temperature.

Do not attempt to operate this water heater

with the cold water inlet valve closed.

Manually operate temperature and pressure

relief valve at least once a year. Standing

clear of the outlet, (discharge water will be

hot), lift and release the lever handle on the

temperature and pressure relief valve to

make sure the valve operates freely.

WARNING

Never operate the heater if it is not com-

pletely filled with water. To make sure the

heater is filled, open the hot faucet of an

upstairs tap, until there is a full flow of water

with no air coming through the tap.

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

severe burns instantly or death from scalds.

Flue Pipes

Children, disabled and elderly are at highest risk of

being scalded.

Once a year, inspect the flue pipe leading from the heater to

the chimney. If corrosion is evident, or discolouration at the

joints can be seen, replace the flue pipes. This should be

done by a qualified Oil-Burner Technician. Flue pipes must

be replaced by the same size flue pipe as the flue collar

(breech connection) at the heater.

Feel water before bathing or showering.

Temperature limiting valves are recommended.

WARNING: HOT WATER CAN PRODUCE 3RD DEGREE

BURNS IN 6 SECONDS AT 140 F (60 C) IN 30 SECONDS

Combustion Tests

Burner adjustments:

AT 130 F (54 C)

Thermostats are factory set at 49°C (120°F). Contact a qual-

ified Oil-Burner Technician for adjustment. Set the tank ther-

mostat as low as possible to provide an adequate supply of

hot water. This will conserve oil and extend the life of the

tank.

Final burner adjustments must be made using combustion

test equipment to assure proper operation. Do not fire

heater without water or sections will overheat.

1. Refer to burner manual for start-up.

2. Allow heater to heat to design condition.

3. Using combustion test equipment, adjust burner for:

V) MAINTENANCE

General

a. CO between 11% and 12% and a trace of smoke

Do not attempt to repair your water heater. Call a qualified

Oil-Burner Technician for service. Turn “OFF” the electric

power whenever the water supply is shut off. Before calling

for service, check that:

between No. 0 smoke and No. 1 smoke.

b. over-fire draft -0.01 to -0.02 in. (-0.254 to -0.508mm)

water column draft in combustion chamber (+0.25 in.

(+6.35mm) for JWF307V).

1. The heater is properly filled.

2. The electrical supply has not been interrupted.

NOTE: For JWF307V also see additional “Installation

Instructions for Through-the-wall Venting Components",

63391, that is supplied with the JWF307V.

Professional Maintenance

Except for external appearance and area tidiness, the fol-

lowing steps should be performed only by a qualified Oil-

Burner Technician.

General Maintenance (by owner)

As a precaution against fire, and to maintain an adequate

flow of combustion air to the heater:

1. Lift out the flue baffle to clean the flue. (On rear and com-

bination flue heaters, the top cover, insulation and flue

top cover must be removed.)

2. Insert a flue brush down the flue passage way(s) to

remove soot and dirt. Soot or carbon that falls into the

combustion chamber will burn up within a very short

time.

3. In normal use, there should be no large accumulation of

soot in the combustion chamber. If there is, remove the

burner and carefully brush or vacuum the combustion

chamber.

•

Keep the appliance area clear and free from com-

bustible material, gasoline and other flammable vapors

and liquids.

Keep the air ventilation openings unobstructed. If dust

and lint is seen accumulating around the openings,

remove it.

Do not pile cartons, papers, or combustible materials on

top, or near the heater (see Figure 1).

ter that may have entered the system. Close the cold

water supply valve when clean water flows.

Temperature and Pressure

Relief Valve

6. If the heater is to remain empty for an extended period of

time, it is suggested the drain valve be left open. When

draining is complete, the hose may be removed.

7. Perform any other servicing as required.

8. Close the drain valve and disconnect hose.

9. Follow instructions for “Filling the Water Heater” and

“Startup” when heater is ready to be put back into ser-

vice.

Manual Relief Valve

Cathodic Protection

Discharge line to drain

Your water heater has been equipped with one or more

anodes that protect the glass-lined tank from corrosion and

prolong the life of the water heater. Over time, as the

anode(s) works, it slowly dissolves, exposing the steel inner

core. Once the anode(s) is depleted, the tank will start to

corrode, eventually developing a leak. Depending on water

conditions, an anode(s) can last from one to ten years. Many

localities treat their water and this can have a significant

effect on the life of your heater. Water conditioning, such as

over-softening, can accelerate the rate at which the

anode(s) is consumed. As with any water heater, it is good

practice to check the anode(s) annually to see if it needs

replacing. Do not remove this anode(s) permanently as it

will void any warranties, stated or implied. Rapid deple-

tion or failure to maintain the anode can leave a heater

unprotected and may result in premature failure of the

heater due to corrosion and leaks.

Figure 12 T&P VALVE TEST.

WARNING! The temperature and pressure relief valve

must be manually operated at least once a year. Caution

should be taken to ensure that:

1. No one is in front of or around the outlet of the temper-

ature and pressure relief valve discharge line.

2. The water manually discharged will not cause any bod-

ily injury or property damage. The water may be

extremely hot.

If, after manually operating the valve, it fails to completely

reset and continues to release water, immediately close the

cold water supply valve, drain the tank as directed in the

“Draining and Flushing” section, and replace the tempera-

ture and pressure relief valve with a new one. Failure to

install and maintain an approved temperature and pressure

relief valve will release the manufacturer from any claim that

might result from excessive temperature or pressure.

This series of oil fired water heaters are factory equipped

with 1 or 2 anodes, depending on the model. The JW717/

JW727 models are equipped with one heavy duty anode.

Under normal circumstances, these anodes should last the

life of the tank and need not be replaced.

Draining, Flushing and Sediment

Removal

Some maintenance and service procedures require that the

heater be drained and empty. The water heater should also

be drained if being shut down for an extended period of time.

Water may contain fine particles of soil and sand which set-

tle to the bottom of a tank and thus form a layer of sediment.

The action of the anode may also help to form sediment. If

not removed, the heater could develop a tendency to pound,

gurgle, or thump when heating up. It is recommended that

the tank be drained and flushed on a regular basis to

remove any sediment that may buildup during operation. To

drain the tank and remove the sediment:

1. Turn "OFF" the electrical supply to the water heater.

2. Close the cold water supply valve.

3. Attach a hose to the drain valve and route to an adequate

drain.

CAUTION! The water being drained can be extremely

hot! The drain hose should be rated for at least 93°C

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

cold water supply valve and a nearby hot water faucet

served by the system until the water flow is no longer hot.

Close the cold water supply valve and resume.

4. Open the drain valve using a flat-blade screwdriver. A

nearby hot water faucet must be opened to allow the tank

to be fully drained.

Hot Water Odour

On occasion, and depending on your location, hot water

may develop a strong odour. This can be especially prob-

lematic in regions where the water contains sulphur, which

results in hot water having a "rotten egg" odour. If this

occurs, drain the system completely, flush thoroughly and

refill the tank. If the water odour or discoloration persists, the

anode(s) may need to be changed from magnesium to one

made of aluminum. Aluminum anodes may reduce, but not

eliminate, water odour problems. The water supply system

may require special filtration equipment from a water condi-

tioning company to successfully eliminate all water odour

problems. In certain cases chlorinating and flushing of the

water heater may be required. Contact your dealer or water

supplier.

Discoloured Water

•

Water rich in iron or other minerals can produce red or

brown staining. Heating water generally worsens this sit-

uation.

5. Open the cold water supply valve and flush the tank as

needed to remove sediment and any other foreign mat-

areas where the water is obtained from surface or cont-

aminated sources. Organic particles can develop bacte-

rial growth, causing potential health hazards.

Contact your water supplier for proper filtration or water

For bacterial problems contact your local health author-

ity. See also “Hot Water Odour”.

A sudden appearance of rust-coloured water may indi-

cate that the anode(s) has been depleted. Once deplet-

ed, the anode’s inner steel core becomes exposed

Cleaning Instructions, Flue Passages Of

The JWF657 Heater

•

Refer to Figure 13 for components of the heater.

1. Remove the casing top and lift if off completely. It is nec-

essary to disconnect the hot and cold water lines and

move them out of the way. Do not remove the nipples

from the tank.

2. Lift off the flue collector. The flue collector has a lip on

the outer edge which will allow a hook to grab the edge

to help lift it up.

Anode Maintenance

3. Remove the flue baffles (4).

A new anode is about 20mm (13/16 in.) to 22mm (7/8 in.)

diameter and has a steel wire core approximately 3mm (1/8

in.) diameter in the center. If the anode is less than approx-

imately 10mm (3/8 in.) in diameter, or the inner steel core is

exposed, the anode(s) should be replaced. Operating a

water heater without an actively working anode(s) will void

the warranty.

4. With a 76mm (3 in.) diameter wire brush, 1.2m (4 ft.)

long, remove any soot build-up which may be on the top

head or inside the flue collector.

5. Reassemble in reverse order. It may be necessary to

replace the gaskets around the nipples to seal them at

the flue collector. Replace the insulation and the casing

top.

6. Reconnect the plumbing lines.

To check/replace the anode:

1. Turn "OFF" the electrical supply to the water heater.

2. Close the cold water supply valve.

Close the cold water supply valve and resume.

5. Remove the anode cover, or, on JWF657, Rear and

Combination flue models, remove top cover, insulation

and flue top cover.

NIPPLES

NOTE: The anode(s) has been factory installed using a

power tool. It may be necessary for a second person to sta-

bilize the heater. A few sharp blows on the handle of the

socket wrench should loosen the anode nut. If an impact

wrench (power drive) is available, this is an easier way to

remove an anode.

6. Using a 1 1/16" socket (certain models require 1-5/16”)

, remove the anode(s) and inspect it. The surface may be

rough, full of pits and crevices, but this is normal. If it is

less than approximately 10mm (3/8 in.) in diameter, or

the inner steel core exposed, the anode(s) should be

replaced.

plumber for directions applicable to the

heater.

2. The water heater must not be connected to a hydronic

heating system that has been used previously.

3. No boiler treatment chemicals of any kind shall be intro-

duced into the system.

1. Shut off the oil supply at the tank.

4. The Combo System components must be selected and

sized to meet and maintain the total calculated demands

for both domestic service hot water and space heating

requirement. The sizing and installation must be per-

formed in accordance with good engineering practice

such as ASHRAE Handbooks, HRAI, Hydronics Institute

Manuals, CGA B149, NFPA 54, ANSI Z223.1, CSA

F280, National/Provincial Building Codes, CSA C22.1,

ANSI/NFPA 70, CSA B51 and/or codes having jurisdic-

tion.

5. The air handler (fan coil) and/or the circulating pump in

a heating loop will require a dedicated 120V circuit. This

must be provided and identified for this purpose.

6. All piping between the water heater and the air handler

or heating loop must be adequately insulated to reduce

heat loss.

2. Shut off the cold water supply to the heater.

3. Turn "OFF" the electrical supply to the water heater.

4. Connect a hose to the drain valve and drain as directed

in “Draining, Flushing and Sediment Removal”.

5. Leave the drain hose attached as a reminder that the

tank has no water in it.

Re-Starting The Heater After Shut-Down

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. 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.

7. If the local jurisdiction requires a back-flow preventer in

the cold water line, an expansion tank of adequate size

must be installed.

8. To reduce the scald hazard potential, a mixing valve

must be installed.

Installation

The heating mode may be one of the following options:

1. Follow instructions for “Filling the Water Heater” and 1. A fan coil/air handler (Figure 14).

3. A hydronic in-floor heating loop (Figure 16).

2. If the heater does not start, check to see if the relay on In order to connect a heating loop to the water heater you

the burner has tripped. Reset if necessary. Check to see must:

if the thermostat is set at “Normal” or “High”.

3. If the heater does not start:

1. Install shut-off valves and unions so that the water

heater can be isolated from the heating module should

servicing of the water heater become necessary.

2. Install a drain valve at the lowest point of the heating

loop so that water can be drained from the heating mod-

ule without affecting the water heater.

a) Turn "OFF" the electrical supply to the water heater.

b) Shut off the oil supply at the tank.

c) Call a qualified Oil-Burner Technician.

VI) COMBINATION HEATING

•

If the air handler does not have a venting means, install

an air bleed at the highest point of the plumbing

arrangement.

Combination Potable Water Heating and

Space Heating (Combo)

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. It is writ-

ten for those knowledgeable in the required trades and pro-

fessionals 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 effec-

tiveness and safety of the installation.

UNIT OR ITS FITNESS FOR A PARTICULAR PURPOSE, MERCHANTABILITY, INSTALLATION, OPERATION, REPAIR OR

BILITIES EXCEED THE COST OF THE DEFECTIVE PART(S) OR UNIT. GSW WILL NOT PAY FOR ANY TRANSPORTATION,

LABOUR, INSTALLATION, OR OTHER INCIDENTAL COSTS ASSOCIATED WITH THE REPAIR OR REPLACEMENT OF A

DEFECTIVE PART OR UNIT.

This warranty and GSW's obligations shall be construed and determined in accordance with the laws of both the Province of Ontario, and of Canada in force

or consequential loss, nor damage(s) related thereto, suffered by the

owner of the Unit nor by any third party.

3. The Unit shall not be installed where it will be exposed to adverse or
