Using the gas hob

Before first use
IMPORTANT: You should clean the hob surface (see “Cleaning and maintenance” section).
Switching the hob on
The following symbols will appear on the control panel, next to each control knob:

= gas off
Large flame: maximum setting
Small flame: minimum setting

• The minimum setting is at the end of the anti-clockwise rotation of the control knob.
• All operation positions must be selected between the maximum and minimum position.
• Never select a knob position between the maximum and off position.
• The symbol on the control panel, next to the control knob will indicate which gas burner it operates.

Automatic ignition with flame failure safety device
The appliance is fitted with a flame failure safety device on each burner, which is designed to stop the flow of gas to the burner head in the event of the flame going out.
To ignite a burner:

• Press in the control knob of the burner that you wish to light and turn it anti-clockwise to the maximum position.
• If you keep the control knob depressed, the automatic ignition for the burner will operate.
• You should hold down the control knob for 20 seconds after the flame on the burner has lit.
• After this 20 second interval, turn the control knob to your required setting between the maximum and minimum setting symbols.
• To switch the burner off, turn the control knob fully clockwise to the gas off position.
• In case of power failure, the burners can be lit by carefully using a match.

Energy saving tips

• The diameter of the bottom of the pan should correspond to that of the burner.

• The burner flame must never extend beyond the diameter of the pan.

• Use flat bottomed pans only.

Cleaning

Cleaning operations must only be carried out when the hob is cool.
The appliance should be disconnected from your mains supply before commencing any cleaning process.
Cleaning the hob top
Any residues that are left on the hob top surface from cleaning agents will damage it. You should remove any residues with warm soapy water.
Abrasive cleaners or sharp objects will damage the hob surface; you should clean it using warm soapy water.
Although it is easier to clean some deposits whilst the hob surface is still warm. Make sure that the hob surface, pan supports and hob burners have all cooled sufficiently before you attempt to touch them.
After each use

• Remove the pan stands and wipe the appliance over with a soft, damp cloth that has been put into warm soapy water.
  The cloth should be wrung out after being taken out of the soapy water.

• Dry the appliance by rubbing the surface with a soft, clean cloth.

• We would recommend that an appropriate stainless steel cleaner and polish is regularly used on the stainless steel surfaces of this appliance.

Cleaning the hob burners
The hob burners should be cleaned once a week or more frequently if they get soiled.

• IMPORTANT: Make sure that the hob surface, pan stands and hob burners have cooled before you attempt to touch them.
• Remove the hob burners by pulling them upwards and away from the hob top.
• Soak them for about ten minutes in hot water and a little detergent.
• After cleaning and washing them, wipe and dry them carefully.
• Before placing the burners back on the hob top, make sure that the gas jet is not blocked.
• IMPORTANT: Make sure that you reassemble the burners in the original way.

Maintaining the cast iron pan stands

• IMPORTANT: Make sure that the hob surface and pan stands have cooled before you attempt to touch them.
• Wipe the pan stands over with a soft, damp cloth that has been put into warm soapy water. The cloth should be wrung out after being taken out of the soapy water.
• Using a paper towel, thoroughly dry the pan stands.
• To maintain the appearance of the cast iron pan stands, we would recommend that you rub a small amount of olive oil into the pan stands, after you have finished cleaning them.

Installation

The installation must be carried out by a GASSAFE registered installer, in accordance with the current version of the following.

• Gas Safety Regulations (Installation & Use)
• Building Regulations (issued by the Department of Environment)
• Building Standards (Issued by the Scottish Development Department)
• IEE Wiring Regulations
• Electricity at Work Regulations BS 6172
• Installation of Domestic Gas Cooking Appliances (if necessary, BS 5482 Installation of Domestic LPG Appliances)
• BS 5440 Installation of Flues and Ventilation for Gas Appliances

Positioning
The adjacent furniture must be able to withstand a minimum temperature rise of 85°C above the ambient temperature of the room it is located in, during periods of use.

• This appliance can be located in a kitchen, a kitchen diner or a bed sitting room. IMPORTANT: The appliance must not be installed in a bathroom or shower room.
  This appliance is classified as Class 3 and therefore is to be built into a kitchen unit (depending on size) or 600mm worktop, providing the following minimum distances are allowed:

• The edges of the hob must be a minimum distance of 55 mm from a side or rear wall.

• 700 mm between the highest point of the hob surface (including the burners) and the underside of any horizontal surface directly above it.

• 400 mm between the hob surface, providing that the underside of the horizontal surface is in line with the outer edge of the hob.
  If the underside of the horizontal surface is lower than 400 mm, then it must be at least 50 mm away from the outer edges of the hob.

• 50 mm clearance around the appliance and between the hob surface and any combustible materials.

All models

• IMPORTANT: You must have a gap of at least 25 mm between the underneath of the appliance and any surface that is below it.

• Carefully turn the hob upside down and place it on a cushioned mat.

• Apply the sealing strip (A) provided around the edge of the appliance.

• The protective covering must be removed from both sides.

• Do not leave a gap in the sealing agent or overlap the thickness.

• IMPORTANT: Do not use a silicon sealant to seal the appliance against the aperture. This will make it difficult to remove the hob from the aperture in future if it needs to be serviced.

• Place the clamp (B) over the holes that match the size of the screws. There are one set of screw holes in each corner of the hob. Slightly tighten a screw (C) through the clamp (B) so that the clamp is attached to the hob, but so that you can still adjust the position of it.

• Carefully turn the hob back over and then gently lower it into the aperture hole that you have cut out.

• On the underneath of the hob, adjust the clamps into a position that is suitable for your worktop. Then fully tighten the screws (C) to secure the hob into position.

• If it is installed in a room with a volume that exceeds 11m³, then no air vent is required.
• If there are any other fuel burning appliances in the same room the current edition of BS 5440: Part 2: should be consulted to determine air vent requirements.
• Ensure that the room containing the hob is well ventilated, keep natural ventilation holes or install a mechanical ventilation device (mechanical cooker hood).
• Prolonged intensive use of the appliance may call for additional ventilation, either by the opening of a window, or by increasing the level of the mechanical ventilation device (where present).
• This hob is not fitted with a device for discharging the products of combustion. Ensure that the ventilation rules and regulations are followed.
• The walls behind and near the hob should be resistant to heat, steam and condensation.
• Remember that the quantity of air necessary for combustion must never be less than 2m³/h for each kW of power (see total power in kW on the appliance rating plate).

Gas Safety (Installation and Use) Regulations

Minimum flow adjustment for hob gas taps
All work must be carried out by a GASSAFE registered engineer.
IMPORTANT: Always isolate the hob from the electricity supply before changing the injectors and/or adjusting the minimum flow of the burners.

• Remove all the pan supports caps 、 flame spreaders and knobs.
• Unscrew the screws of the panel, then remove the panel.
• Install cap 、 flame spreader 、 knob of the burner. Switch the burner on and set the knob at the minimum position.
• Place a small bladed screwdriver on the screw to adjust the minimum flow (as shown in the image on the left).
• Unscrew the adjusting screw, in order to increase the gas flow or tighten the adjusting screw to decrease the gas flow.
• The correct adjustment is obtained when the flame has a length of about 3 – 4 mm.
• For butane/propane gas, the adjusting screw must be tightly screwed in.
• Make sure that the flame does not go out by quickly turning from maximum flow to minimum flow. If it does then remove the control knob and make further adjustments to the gas flow, testing it again once the adjustment has been made.
