Blue Seal Evolution series G51 Gas Cooktops
Safety System
The purpose of the safety system is to shut off
the flow of gas if the pilot flame goes out. It is
comprised of the flame itself, the thermocouple,
and the flame failure gas valve.
The pilot flame is lit by holding in the gas
control knob, which in turn temporarily pushes
the plunger inside the safety valve open and
allows gas to flow through. Once the burner is
lit, the thermocouple will begin to generate
millivolts (after about 10 to 30 seconds of being
heated) and will energize the electromagnet
inside the gas valve. Once energized the
electromagnet holds the plunger inside the gas
valve in the open position. The plunger has to
have been pushed all the way in for the
electromagnet to be able to hold it in place. If
the burner flame goes out for some reason, the
thermocouple will cool after about 10 to 30
seconds and stop generating millivolts. The
electromagnet will then de-energize, and the
plunger will snap shut, cutting off the flow of gas.
Detail of each component in the safety system is
explained below.
Thermocouple
The thermocouple is a device that generates
electricity when heat is applied to the tip.
Millivolts are provided to the electromagnet by
the thermocouple (not shown) which generates
millivolts when heated. The thermocouple screws
into a fitting at the back of the gas valve to make
an electric connection. By pressing in the gas
control knob, the plunger can be temporarily held
open while lighting. There's two reasons for this;
gas has to flow through the safety valve to make
it possible to light the pilot burner, and secondly
the plunger has to be pushed all the way in for
the electromagnet to hold it in. I.e.; the
electromagnet is strong enough to hold the
plunger in once there, but is not strong enough
to pull it in by itself. Sometimes a problem with
the flame not staying lit after releasing the button
can be attributed to not pushing the plunger all
the way in.
The tip of the thermocouple is located in the pilot
burner flame, and the nut at the other end of the
thermocouple screws into the back of the gas
valve. Inside the copper tubing is a wire which is
joined at the tip but insulated from the rest of the
tubing. These two parts (the copper tubing and
wire) make up the "wiring" for an electrical
circuit. When these two dissimilar metals, wire
and tip, are heated an electrical voltage is
produced. This type of thermocouple generates
between 7 and 30 millivolts when heated in the
pilot flame.
Electromagnetic Flame Failure Gas Valve
The purpose of the safety valve is to shut off the
flow of gas if the pilot flame goes out.
Inside the body of the gas valve is an
electromagnet connected to a spring loaded
plunger. When the electromagnet is energized, it
holds the plunger in, allowing gas to flow through
the valve. When the electromagnet is
de-energized, the plunger snaps to the closed
position, stopping the flow of gas.

Revision 1/
Blue Seal Evolution series G51 Gas Cooktops
CAUTION:
Always turn off the gas supply before cleaning.
This unit is not water proof.
Do not use water jet spray to clean interior or exterior of this appliance.
Routine Maintenance
To achieve the best results cleaning must be
regular and thorough and all controls and
mechanical parts checked and adjusted
periodically by a competent serviceman. If any
small faults occur, have them attended to
promptly. Don't wait until they cause a complete
breakdown. It is recommended that the
appliance is serviced every 6 months.
Clean the cooktop regularly. A clean cooktop
looks better, will last longer and will perform
better. Carbonised grease on the surface or
between the trivets, griddle plates will hinder the
transfer of heat from the cooking surface to the
food. This will result in loss of cooking efficiency.
DO NOT use water on the trivets, burners and
griddle plates while these items are still hot as
warping and cracking may occur. Allow these
items to cool down and then remove for cleaning.
The entire trivets, griddle plates and burner caps
can be dismantled for cleaning.
NOTE:
DO NOT use abrasive detergents, sharp scrapers,
strong solvents or caustic detergents as they
could corrode or damage the cooktop.
In order to prevent the forming of rust on the
trivets, griddle plate (if fitted) and burners,
ensure that any detergent or cleaning material
has been completely removed after each
cleaning. The appliance should be switched on
briefly to ensure the griddle plates become dry.
Oil or grease should be spread over the griddle
surface in order to form a thin protective greasy
film.
To keep your cooktop clean and operating at
peak efficiency, follow the procedures shown
below:-
After Each Use
Clean the griddle and cooktop castings with a stiff
nylon brush or a flexible spatula to remove any
build up of carbon.
Daily Cleaning
The grease tray(s) should be checked and
emptied frequently to prevent overflow and
spillage.
Remove the grease tray(s) while still warm so
that the grease is in a liquid state. Empty any
grease from the trays and wash thoroughly in the
same manner as any cooking utensil.
Remove the griddle plate, burner caps and bases
and the trivets and thoroughly clean the splash
back and exterior surfaces of the cooktop with
hot water, a detergent solution and a soft
scrubbing brush.
Dry the cooktop thoroughly with a dry cloth and
polish with a soft dry cloth.
Brush the griddle and trivets with a wire brush
followed by wiping with a cloth to prevent
accumulation of carbon.
