Installation manual for Parkinson Cowan Widsor Radiant Gas Fire, circa 1972

Dear Ju, I have not used HOH again, so still don't understand how it works, but I hope that I have attached here what 'Julian57' sent to me. Sadly, our fine gas fire was "terminated" (It didn't fail) by our landlord, and the I couldn't persuade the gas fitters that they sent even to put it onto the secondary market. Please don't trouble to respond, I just hope that the help that I received helps you now.
