Conditions of Guarantee
Your ESSE ooker is guaranteed against defe ts arising from faulty manufa ture for three years, subje t to the following express onditions:
• This ooker must be ommissioned by your ESSE Dealer (or an authorised GAS SAFE engineer) upon installation. The details must
be re orded on the Commissioning Card and registered with ESSE by returning the ompleted ard. The guarantee period om-
men es upon delivery of the ooker (subje t to re eipt of the orre tly ompleted ard).
• The ooker has been used for normal domesti purposes only, and in a ordan e with the manufa turer’s instru tions.
• The ooker is servi ed annually by the ESSE Dealer or authorised GAS SAFE engineer, and the Servi e Re ord ompleted.
• The ooker must not be servi ed, maintained, repaired, taken apart or tampered with by any person not authorised by us.
• Any ooker or defe tive part repla ed shall be ome the Company’s property.
Exclusions
This guarantee does not over:
• Damage OR alls resulting from transportation, improper use or negle t.
• Parts deemed to be repla eable in the normal usage of the ooker. These parts are listed herewith: oven thermostat, gas
valve, piezo ignition lead, pilot assembly, timer/programmer and atalyser assembly.
• Enamel damage; the vitreous oating on your ooker is in effe t an extremely thin layer of glass and as su h displays all the hara teristi s
of glass. It an easily be damaged by impa t, or by spillage of old liquids onto a hot surfa e. Su h damage annot be overed under
this guarantee. (See also intermittent use of your ooker, below).
This guarantee is personal to the original pur haser and is non-transferable.
Intermittent Use of Your Cooker
In the event of intermittent use and prolonged shutdown, it should be noted that in some ir umstan es enamel may be displa ed due to
ingress of damp. Whilst this is rare, it is most likely to o ur in situations where the unused ooker remains in a unheated property. There is a
layer (known as the ground oat) between the vitreous enamel surfa e and the ast iron. Ground oat is porous and if exposed (e.g. after a
hip in the vitreous enamel oat), may allow damp to penetrate behind the vitreous enamel and spread through the ground oat. Surfa e
oxidisation of the ast iron may thereafter o ur, ausing the vitreous enamel to fall off. Su h damage will not be overed by your warranty.
We re ommend that a light oating of petroleum jelly be applied to any damaged areas when the ooker is not in use to help keep out the
damp, in addition to following instru tions in your Operating Manual.
Customer Care
In the event you should require spare parts, please order through your ESSE dealer.
Should you have ause for dissatisfa tion with your ooker, you should onta t your ESSE dealer, who will, in most instan es, be able to
offer you immediate assistan e. You will be required to give the following details.
• Your name, address and post ode.
• Your telephone/ onta t details.
• Clear and on ise details of the fault.
• Model and serial number of the ooker (found on the inside panel of the firebox/ ontrol door).
• Pur hase date (please note that a valid pur hase re eipt or guarantee do umentation is required for in-guarantee servi e alls).
We will then he k that we have an a urately ompleted warranty ard, if not then any work arried out will be harged.
We will a ess the nature of the omplaint and either send repla ement parts for your dealer to fit, send an engineer to inspe t & report, or
send an engineer to remedy. If the fault is not a tually due to faulty workmanship but some other ause su h as misuse or failure to install
orre tly, a harge will be made to over the ost of the visit and any new parts required, even during the warranty period. Home visits are
made between 08 30 - 17 00 hrs. Monday to Friday, and are arranged for either a morning or afternoon appointment.

IMPORTANT NOTES
The ooker must only be used in the manner des ribed. In orre t operation an lead to hazards.
This applian e must be used in manual mode only in an emergen y. Normally an ele tri ity supply is
required to operate in timer mode.
The ventilation arrangements will be made by the installer. Never alter these arrangements by blo king off
the permanent air vents provided by the installer.
Do not light the ooker if it is suspe ted that any part of the hot water system is frozen. Seek professional
help from a plumber.
Take are to avoid tou hing the viewing window or its immediate vi inity when the ooker is alight. These
parts may be hot.
If the ooker is operated under onditions where the ombustion produ ts spill from the flue terminal i.e.
if downdraught or flue blo kage o urs, the spe ial pilot fitted to the ooker will ause the burner to shut
down. If this o urs, onsult your installer for remedial a tion.

The use of a gas applian e results in the produ tion of the heat and moisture in the room in
whi h it is installed. Ensure that the room is well ventilated.
Temperature in abinet storage spa es above the applian e may be unsafe for storage of
some types of materials su h as volatile liquids or aerosol sprays whi h an explode.
Model GN has no boiler; Model GD has a boiler for domesti hot water only.
Your ooker is a ombination applian e, providing hotplate, fast and slow ovens and where appli able,
hot water servi e. A single burner is lo ated under the left hand end of the hotplate. There are two hinged
overs to onserve heat losses from the hotplate when it is not in use.

BEFORE USING YOUR COOKER
Che k that the plasti prote tion oating has been removed from ea h hotplate over, and from the
inside of the oven doors. This should have been done during installation but if the plasti has been left on
it will melt on firing the ooker and ause damage to the insulated overs.
The hotplate surfa e should be wiped with a dish loth or similar, whi h has been soaked with hot water
and a detergent liquid. Finally dry off the hotplate with an absorbent material.
Nominal Heat Input
The nominal heat input, based on the gross alorifi value of the fuel, is 8.8kW. For propane, this
onverts to 629g/hour.
The ooker is ontrolled by a 7 - day ele troni timer and a ontrol valve. A by-pass valve is fitted for use
in event of ele tri al power not being available. The by-pass valve should normally be in the TIMER
TIMERTIMER
TIMER position.
These ontrols are lo ated behind the Control/Firebox Door. (Fig 3).
Burner Control
The ontrol system operates as follows:
• The knob is turned to the lighting position, depressed and the pilot ignited by the igniter. With the
pilot alight, the knob is released and then turned to an ON
ONON
ON position.
• The temperature of the oven is ontrolled by a thermostat lo ated in the top oven. The ontrol
valve ontains a flame failure devi e that shuts off gas to the burner if the pilot is extinguished for
any reason.
Detailed operation of the ontrol is dealt with later in these instru tions under the appropriate headings
Fig. 3 - G s Controls
To Light the Pilot
Open the Firebox/Control Door fully.
1) Turn ontrol knob to PILOT IGNITION
PILOT IGNITION PILOT IGNITION
PILOT IGNITION position (Fig. 4b).
2) Press the knob fully downwards and hold it in.
3) Press igniter button fully downwards and release to obtain a spark (holding this button down
serves no purpose). Repeat until the pilot lights and flame an be seen through the viewing
glass.
4) Continue to hold the knob in for about 10 se onds (a slow ount of 1 to 10) after the pilot ignites.

Hot W ter Output
The domesti boiler model produ es hot water whenever the burner is alight and the amount produ ed is
dire tly related to the oven temperature i.e. the maximum amount is produ ed at the highest oven temperature
and vi e versa.
Oven Temper tures
The approximate temperature at the various knob setting positions are as shown in the OVEN TEMPERATURE
hart on Page 7.

The hotplate is surfa e ground and intended for use with ma hined base utensils. As heat passes
from the hotplate to utensil almost dire tly by ondu tion, good onta t is essential and a thin bottomed
utensil will result in poor heating performan e, espe ially if the bottom is uneven.
The hottest part of the hotplate is the left hand end. The temperature of the hotplate depends on the oven
ontrol setting. In general the higher the oven temperature the higher the hotplate temperature.
Always keep hotplate overs down ex ept when using the hotplate.
The ovens are fitted with anti-pull out stops to prevent shelves from being pulled out a identally. To
insert the shelf lo ate the open end of the shelf on the runners, lift up slightly at the front and push to the
rear to pass the stops, then fully ba k into the oven. To remove a shelf, pull forward until it stops, lift front
end and pull out of the oven.
The top oven has four runner positions for the shelves. The wire shelf is used when ooking two trays of
food at one time. Certain ooking operations an be arried out by pla ing dishes dire tly on the oven
bottom. The oven temperature is ontrolled thermostati ally in a ordan e with the setting sele ted on
the ooker ontrol knob. A thermometer in the door gives an indi ation of the oven temperature, but
sin e it is in the door itself, the thermometer will rea t if the door is opened and the thermometer reading
may fall onsiderably. When the door is losed, the thermometer will re over slowly to indi ate the oven
temperature. A rapid fall in thermometer reading therefore does not indi ate that the oven temperature
has also done so. The bottom oven takes its heat from the underside of the top oven, and is
approximately
3
/
5
of the top oven temperature.
THE HOTPLATE
THE OVENS
When lighting the burner for the first time or when the ooker is ompletely old, there will
be some steam or ondensation due to the mass of old metal. During this warm up period
the hotplate overs should be raised to prevent ondensation entering the overs.
Should the burner and pilot go out at any time, or are turned off by a ident, wait at least
TWO MINUTES before attempting to relight the pilot flame. This period of time will ensure
that the safety devi e within the gas ontrol has ooled and losed, preventing gas flowing
to the burner.
The hotplate must not be removed from the ooker, unless the ontrols are at OFF and the
ooker is isolated from the mains ele tri ity supply.
Do not allow the ooker burner to run for prolonged periods with the top oven door open.

TEMPERATURE SETTINGS
Knob settings between any two numbers an be used if required.
The top oven will rea h operating temperatures in about 60 minutes from old or 30 to 45 minutes if
previously idling at low flame. The most e onomi al ontrol setting will be found by pra ti al usage, but
obviously the lower the temperature setting the greater the e onomy of operation. The ele troni timer
should be set to suit your requirements.
The equivalent gas ooker 'Marks' often quoted in ooking instru tions are shown in the Oven
Temperature Chart.
Routine Servi ing
Like any other gas applian e, the ooker must be regularly servi ed by a qualified servi e engineer at
least on e a year. This will ensure that the ooker remains in a first lass and safe ondition. Your installer
will normally be able to re ommend where servi e an be obtained.
Oven Temperature Chart Knob Position Chart
The thermometer should be used as a general guide but may vary from the temperatures
indi ated above. The thermostat will give repeatable oven temperatures when ooking.
Approximate equivalent Celsius/Fahrenheit and ‘Gas Mark’ (G.M.
G.M.G.M.
G.M.) temperatures are
indi ated in the OVEN TEMPERATURE hart. If the oven temperatures are not repeatable,
this may indi ate that the thermostat requires repla ing.
On ompletion of the servi e, the engineer should fill in the Servi e Re ord se tion of the
Installation Instru tions. As well as issuing you with the relevant Gas Safe paperwork for
your applian e.

TIPS FROM THE ESSE KITCHEN
En mel Cle ning
Enamel is simply a oloured glass oating added to the metal to give a durable and hygieni finish. It an be
damaged by s rat hing or by a sudden appli ation of old liquids onto its surfa e when hot. Clean with a loth
and soapy water, preferably while ooker is still warm. Proprietary non-s rat h liquid leaners for enamelled
surfa es may be used. Spilled liquids should be removed as soon as possible. Fruit jui es and other a idi
produ ts an remove the gloss surfa e from the enamel if left for any period of time.
Pots nd P ns
It is important to use pots and pans that have a ground base and are flat-bottomed on the hotplate.
Cookware made of stainless steel, ast iron, aluminium, glass and earthenware is suitable for your ESSE.
The Hotpl te
The temperature versatility here is very important - the area of the hotplate over the left hand end burner
is the hottest, while the area over the oven is ooler. Qui k boil on the former and then transfer for
simmering on the latter.
For deep fat frying, bring to temperature on the 'right' side. Introdu e old food and then return to
temperature on the 'hotter' left side.
Cooking dire tly on the hotplate is another fa ility - griddle s ones, burgers, sausages, steaks, and even
Welsh Rarebit an be ooked dire tly on the surfa e.
Meringues an be dried on a baking tray sitting on the hob overnight.
Additionally, by using a barbe ue griller you an produ e your own toasted sandwi hes on the oven top.
The hotplate an be rubbed down with a proprietary leaning pad if ne essary, but normally should need
no attention unless spillage is allowed to harden on its surfa e.
Care must always be taken when handling foods in the home.
Always follow the basi rules of food hygiene to prevent ba terial and mi robial growth and ross
ontamination when defrosting, ooking, ooling and freezing foods.
