CONVERTING A HEATER FROM NATURAL GAS (I2H) TO LPG(I3P)
1)
If the heater is already installed, switch off the gas and electricity and remove the heater to ground level.
2)
Remove the injectors.
3)
Replace the injectors with the correctly sized injectors for propane (see table).
4)
Re-install heater and connect electrical and gas supply.
5)
Connect gas pressure gauge to operating pressure test point on the outlet of the gas valve (see section on
commissioning).
6)
Switch on the heater.
7)
Read the operating pressure from the pressure gauge. This must be adjusted to 25 mbar.
8)
Remove the sealing ring on the governor adjusting screw. Turn the screw clockwise to increase the gas
pressure to 25mbar. (see section on pressure adjustment on page 13)
9)
When the operating pressure has stabilised at 25 mbar, switch off the heater.
10)
Remove pressure gauge and replace pressure test point screw.
11)
Re-seal the governor adjusting screw using the sealing ring.
12)
Replace or amend the heater data badge to show that it has been adjusted for LPG.

CONVERTING A HEATER FOR OPERATION ON NATURAL GAS
(I2E+) IN FRANCE OR BELGIUM
Follow the procedure outlined above for conversion of a heater for operation on Natural gas.
The gas valve on the heater (SIT valve model 0.830.040) must be replaced with a different valve (SIT valve model
0.830.010). This valve incorporates a gas flow adjuster instead of a governor. Follow the procedure outlined in
section "Replacement of gas valve".
The operating pressure must be adjusted to 15mbar as described above.
Seal the flow rate adjuster screw using the sealing ring.
Replace or amend the heater data badge to show that it has been adjusted.
WARNING: The inlet gas pressure must not exceed 20mbar for G20 or 25mbar for G25 on heaters equipped
with flow adjuster.
