Gas Installation; Testing Gas Pressure; Testing The Flue System - Jøtul GF 3 CF Instrucciones Para Instalación

ENGLISH
All brick flues or any flue previously used with solid fuel or
gas appliances must be left with the appropriate debris
collection volume below the flue spigot of the stove of 12
lites minimum, and depth of 250mm minimum below the
spigot. Block, clay, cement or steel lined (connected to the
top of the fireplace opening) flues either new or previously
used with GAS appliances may have the smaller debris
collection volume of 2 litres minimum and depth of 75mm
minimum below the flue spigot.
Make sure that there will be at least 50mm clearance
between the end of the spigot and knee of the fireback for
flue gasses. Also make sure that the spigot will pass through
the closure plate by a minimum of 15mm. It can be extended
by up to 150mm (6") to ensure this requirement is met
using a purpose made extension or suitable piece of flue
pipe.
Cut a closure plate from sheet aluminimum or steel to just
cover the fireplace opening to be used. It is also possible to
use other fireproof materials providing they are properly
supported and sealed and can be removed annually for
inspection and clearing of the flue. Cut a spigot hole as
shown in the diagram. Fix the closure plate to the wall or
fireplace and seal it correctly to the wall. The plate must be
sealed correctly to the wall using adhesive sealant, screws
and/or tape able to withstand at least 3 degrees C. The
appliance will not work correctly and may cut out
repeatedly if the sealing of the fireplace and flue is not
correct.
Remember if the closure plate will show around the sides
or top of the stove, a non combustible decorative panel
can be fitted to cover the area. The closure plate can then
be fitted to this. Marble infill panels are a common
example.
Install the appliance and connect to the gas supply and
carry out a smoke test on the flue as described in the
relevant section.

Gas installation

Gas installation must only be performed by qualified
personnel. It is important to adhere to national and local
regulations that apply.
The gas container must be stored/installed according to
regulations.
The gas container must have a pressure regulator that
reduces the pressure to the required level. (See technical
data for gas type and pressure before connecting to the
fireplace. The appliance must not be exposed to pressure
above 55 mbar (5,5 kPa) during pressure testing.
Gas tubes must be made of steel (DIN 2448/1629, DIN 2458/
1626, DIN 2440, DIN 2441) or copper (DIN 2110).
For practical reasons, the vent system should be installed
before the appliance is connected to the gas supply.

• All tube connections must be approved for LPG and
• The gas pipeline must have an approved shutoff valve.

Testing gas pressure (Fig. 3)
Correct gas pressure is important for the safe use of gas
in the appliance. The installer must set the correct gas
pressure during the installation of the appliance. The gas
valve is equipped with testpoints for the testing of gas
pressure. These are located underneath at the right side
of the product.
Right testpoint (A): For gas pressure to the valve (volume
of gas to the valve) See technical data.
Left testpoint (B): For gas pressure from the valve (volume
of gas coming out of the valve to the burner).
• Always test the gas pressure with the valve control knob
• Loosen the screw in the outlet and attach the tube from
Adjusting gas pressure (fig. 3)
• To adjust the gas pressure use a small screwdriver and
• Turn the gas rate to low and adjust the lower pressure

Testing the flue system

Once the appliance is fitted, gas leak and pressure tested,
and the flue system complete, the flue must be checked
for correct operation. This is best achieved after 10 minutes
of burning by holding a smoke match just inside the
downdraught diverter hood on the rear of the appliance
(accessible through a cutout in the rear heatshield). The
smoke should be drawn into the flue and no smoke should
spill into the room. If the smoke does issue into the room,
leave for another 5 minutes and retest.
The appliance is fitted with a TTB (flue sensing safety
switch) so if the fire does cut out automatically during this
testing, or smoke persists to come into the room when
tested, this indicates a problem with the flue system which
must be thoroughly measured, checked and rectified before
allowing use of the appliance.
