salam,
yesterday i switched on my japanese heater and it was emitting very strong smell.
it was working perfect for 5 days since i bought it but yesterday the smell was so strong after 30 min of use my eyes started to rash and whenever someone entered my room asked me to switch it off otherwise it will suffocate me.
i took of the heater and realized from the gas pipe there was also very smelly oil coming from the sui gas pipe.
what could be the reason? is it the heater or the sui gas pipe is suppplying different sort of gas which is giving hard time to the heater?
the heater is still in replacement warranty.
