Could of burned my house done.

Good afternoon<br> <br> I bought a logic LM1105 Roll about 3 Piece heater from Game. <br> So i am currently away, so my girlfriends step father installed a Gas bottle into the heater, He then functioned check it for leaks etc and everything went well. <br> <br> My Partner then tuned on the heater some time later. the heater was running fine and then suddenly the regulator burst into flames. Causing Burn to her left arm.<br> <br> she is lucky that is the only damage she obtained it could of been alot worse and my house could of burned down.<br> <br> I will not settle for this was a mistake, This heater should of been checked before selling.<br> <br> regards<br> tyon
