Hi Gary,

Thanks for the question, the unit can give off a smell of gas while being used, but if it is extreme during use it could be incomplete combustion caused by low gas pressure.
If however the smell is there permanently a service call will be recommended to find root cause.

Please contact 1st care service on 1300 555 545 for further assistance if required.

Thanks,
