Gas Installation - Jøtul GF 3 CF 2 Installation And Operation Instructions Manual

Gas Installation

Gas installation must only be performed by qualified
personnel. It is important to adhere to national and local
regulations that apply. In the UK these include BS5440 Pt
1&2 and BS5871 in Ireland.
The LPG gas container must be stored/installed
according to national regulations. The gas container must
have a pressure regulator that reduces the pressure to
the required level. See technical data on page 4 for gas
type and pressures before connecting to the appliance.
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.
The stove is supplied with a 3/8" to 8mm compression
union. The gas valve has a 3/8" NPT threaded connection.
All tube connections must be approved and the gas
pipeline must have an approved shutoff valve. Only use
approved sealing agent (tape) at all the pipe connections.
When the pipe sections have been assembled and con-
nected to the appliance, open the gas supply and light the
appliance (see lighting instructions). Perform a tightness
test on all the pipe connections.

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 appli-
ance, 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). If the fire does cut out automatically during flue
testing, or if smoke persists to come into the room when
tested, a problem is indicated within the flue system which
must be thoroughly measured, checked and rectified
before allowing use of the appliance.
Testing Gas Pressure
Correct gas pressure is important for the safe use of gas
in the appliance. It is important that the correct gas
pressure is set during the installation of the appliance.
The gas valve is equipped with outlets for the testing of
gas pressure. The outlets are located at the front of the
valve below the ON/OFF/Pilot knob. The outlets are marked
as shown in fig.16.
Outlet D: For gas pressure to the valve (volume of gas to
the valve) See technical data.
Outlet E: For gas pressure from the valve (volume of gas
coming out of the valve to the burner).
C: Regulator - Always test the gas pressure with the valve
regulator knob on High (Hi).
Loosen the screw in the outlet and attach the tube
from the manometer to the outlet. Remember to
tighten the screw when the testing is completed and
test for leaks at the outlets with test fluid.
Required gas pressure from the vent (Outlet E) is dis-
played in the table below.
