thoroughly on a frequent basis, keeping in mind the following:
› The enameled parts must be washed with warm water without using abrasive powders or
corrosive substances which could ruin them;
› The removable parts of the burners should be washed frequently with warm water and soap,
making sure to remove caked-on substances;
› The end of the electronic ignition device must be cleaned carefully and frequently, making sure
that the gas holes are not clogged;
GREASING THE GAS VALVES:
Over time, the gas valves may stick or become difficult to turn. If this is the case, they must be
cleaned on the inside and the re-greased.
NOTE:
This procedure must be performed by a Caple approved engineer or similar qualified persons.

INSTALLATION INSTRUCTIONS
Installation should only be attempted by a qualified installer so that the installation and
maintenance procedures may be followed in the most professional and expert manner possible.
IMPORTANT:
Unplug the electrical connection before performing any maintenance or regulation upkeep work.
POSITIONING FOR GAS HOB
IMPORTANT:
This unit may be installed and used only in permanently ventilated rooms according to British
standards.
The following requirements must be observed:
› The room must be fitted with a ventilation system which vents smoke and gases from
combustion to the outside. This must be done by means of a hood or electric ventilator that
turns on automatically each time the hood is operated.
› The room must also allow for the influx of the air needed for proper combustion. The flow of
air for combustion purposes must, not be less than 2m³/h per kW of installed capacity. The
supply of said air can be effected by means of direct influx from the outside through a duct
with an inner cross section of at least 100cm² which must not be able to be accidentally
blocked.
› Intensive and prolonged use of the appliance may necessitate supplemental ventilation, e.g.
opening a window or increasing the power of the air intake system (if present).

GAS HOB INSTALLATION
The gas hobs are prepared with protection degree
against excessive heating of type X, the appliance can
therefore be installed next to cabinets, provided the
height does not exceed that of the hob. For a correct
installation of the cooking hob the following precautions
must be followed:
› The hob may be located in a kitchen, a kitchen/diner
or bed sitting room, but not in a bathroom or shower
room.
› The furniture standing next to the hob, that is higher
than the worktop, must be placed at least 110mm
from the edge of the hob.
› The cabinets positioned next to the hood should be at
a height of at least 420mm (Fig. 5).
› You must have a gap of at least 25mm bewteen the
underside of the hob and any surface that is directly
below it.

In the event the hob is not installed above a built-in oven, a wood panel must be inserted as insulation.
This panel must be placed at least 20 mm from the bottom of the hob itself.
Important: When installing the hob above a built-in oven, the oven should be placed on two wooden strips;
in the case of a joining cabinet surface, remember to leave a space of at least 45 x 560 mm at the back.

When installing on a built-in oven without forced ventilation, ensure that there are air inlets and outlets for
ventilating the interior of the cabinet adequately.
Gas connection for gas hob
The hob should be connected to the gas-supply by a Gas safe registered installer. During installation of this
product it is essential to fit an approved gas tap to isolate the appliance from the supply for the convenience
of any subsequent removal or servicing. Connection of the appliance to the gas mains or liquid gas must be
carried out in compliance with current regulations, and only after it is ascertained that it is adaptable to the
type of gas to be used. If not, follow the instructions indicated in the paragraph headed "Adaptation to
different gas types". In the case of connection to liquid gas, by bottle/tank, use pressure regulators that
conform to current regulations in force.
Important: For safety, for the correct regulation of gas use and long life of the appliance, ensure that the
gas pressure conforms to the indications given in table 1 "Burners and injector specifications".
Connection to Gas supply by rigid metal pipe
(Copper or steel)
Connection to the gas source must be done in such a way as to not create any stress points at any part of
the appliance.
The appliance is fitted with a 1/2” gas male ‘L’ shaped union and a gasket for the attachment to the gas
supply.
Should this union have to be re-positioned, the gasket must be replaced.
Connection to flexible steel tube
The gas feed connector to the appliance is a threaded, male 1/2" connector for round gas pipe. Only use
pipes and sealing gaskets that conforms to the standards currently in force. The maximum length of the
flexible pipes must not exceed 2000 mm. Once the connection has been made, ensure that the flexible
metal tube does not touch any moving parts and is not crushed.
Check the Installation
Once the appliance has been installed, make sure all the connections are properly sealed, using liquid
detector fluid and a ‘U’ gauge. Never use a flame.
Electrical Connection
(The hob is fitted with a standard 13amp plug)
Fit the supply cable with a standard plug for the demand rate indicated on the rating plate or connect it
directly to the electrical mains. In the latter case, a single pole switch must be placed between the appliance
and the mains, with a minimum opening between the contacts of 3 mm in compliance with current safety
codes (the earth wire must not be interrupted by the switch). The power supply cable must be positioned so
that it does not reach a temperature in excess of 50~C above room temperature at any point.
Before actual connection make sure that:
