Instructions For The Installer - Technika TGG85U Operating And Installation Instructions

OVEN BURNER
(fig. 23)
The burner is installed on the oven base and is covered
by the bottom plate which must always remain in that
position during oven operation,
To adjust the primary air, is performed when the
burner is ignited, by adjusting the sleeve (B) and
unscrewing screw (A). Lock screw (A) in place once
the adjustments have been made (see on TECHNICAL
FEATURES paragraph).
NOTE:
Oven Failure
• Check thermocouple terminal.
• Inspect rear of thermostat (under hob) to check that
thermocouple connections are "tight" and parallel to
each other.
• Check thermostat knob for sufficient clearance from the
control panel to allow electromagnet to fully seat.
• If above cannot solve the problem, replace
thermocouple.
Oven Ignition Failure
• Ensure that the electrode lead is not "earthing" against
cabinet.
• Check spark gap from electrode tip to burner. Should be
only 5-6 mm.
• Check ceramic body of electrode for obvious damage
or cracks.
• If no spark at all, check ignition box failure or power
source.
Hot Plate Ignition Failure
• Check alignment of burner holes to electrode.
• Check aeration sleeve for adjustment for gas type,
location and ambient conditions.
• No spark, check ignition box failure or power supply.
Before Leaving
• Check all connections for gas leaks with soap and water.
DO NOT use a naked flame for detecting leaks. Ignite
all burners to ensure correct operation of gas valves,
burners and ignition.
• Turn gas taps to low flame position and observe stability

of the flame. When satisfied with the cooker, please
instruct the user on the correct method of operation.
• In case the appliance fails to operate correctly after all
checks have been carried out, refer to the authorised
service provider in your area.
GAS CONVERSIONS
When converting from Natural Gas to LPG ensure that
the NG regulator is removed and replaced with the
Test Point Assembly. An AGA Approved gas regulator
suitable for a supply pressure of 2.75 kPa should be
part of the gas tank supply and the test point pressure
should be adjusted to 2.75 kPa.
Replace the old data plate with one, which is suitable
for the type of gas for which the appliance has been
regulated.
REPLACING THE INJECTORS
Our burners can be adapted to different types of gas
by simply installing the injectors suitable for the gas
you want to use. To help the installer, the table (see on
TECHNICAL FEATURES paragraph) gives the burner
nominal heat input, injector diameter and operating
pressure of the different gas types.
Comply with the following instructions:
Injector replacement - Hob burners.
To change the injectors on the hob, remove the burner
cup and head and with a 7 mm Ø socket spanner
replace them (fig. 24).
Injector replacement - Oven burner.
Remove oven base. Remove screw (D) (fig. 23) which
will release burner and give access to the injector (C).
Unscrew injector and replace it. Replace burner and
replace screw (D).
After having replaced the injectors, it will be
necessary to proceed with burner adjustment as
explained in the previous paragraphs.
