Genuine Toshiba owner's manual. Couldn't really ask for more. And written in understandable English in contrast to a few recent experiences I have had with manuals for other equipment other than Toshiba but made in China and written in "Chinglish"!
I purchased a vintage Sony mixer off eBay and within the hour was able to locate and purchase the manual for it.I mean really,where else can you find a manual for a product made in 1983!? It was easy to find and purchase/download the manual I needed.I will use this site again for other equipment I have! Great site!
It`s full copy of a service manual from url http://www.philips.owner-manuals.com/PM3216-service-manual-PHILIPS.html

Conversion from Natural Gas to LPG
It is important to note that this model is designed for use with natural gas but can be converted for use with butane or propane gas providing the correct injectors are fitted and the gas rate is adjusted to suit.
F 1) Ensure that the gas taps are in the 'OFF' position
2) Isolate the hob from the electricity supply 3) Remove all pan supports, burner caps, rings, crowns and control knobs. 4) With the aid of a 7mm box spanner the burner injectors can then be unscrewed and replaced by the appropriate LPG injectors.
To adjust the gas rate
With the aid of a thin bladed screwdriver completely tighten down the by pass adjustment screw. Upon completion stick the replacement rating plate on the under side of the hob. IMPORTANT The replacement/conversion of the gas hob should only be undertaken by a competent person.
