A2.1 Conversion to LPG Propane
Note: It is strongly recommended that, on LPG installations, gas detection equipment is fitted. This equipment
should be positioned near the boiler and at low level. It is important that the space housing the boiler is
adequately ventilated at high and low level - refer to Appendix D.
For single module installations, ie 1 x Milborne 381 / 501, the boiler must not be installed in a room or
compartment located below ground level. BS6798.
For multiple module installations, ie 1 x Milborne 382 / 502 or greater, the boiler must not be installed in a plant
room located below ground level. BS6644.
