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 ac-
cording 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 connec-
tion. 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.

Commissioning
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 min-
utes 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), located on the draft hood on the back of the
stove. 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 recti-
fied 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.15.
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 displayed
in the table below.
