In lighting it, i meant, do i turn the gas on and put my hand inside the furnace and put a lighted match or lighter to the end of the burner or do i light it outside the furnace at the air intake. I have not used it yet as i am still waiting for a POL cylinder fitting to come from China before i can connect to Australian gas cylinders. I have read up a lot on the internet hence all my previous questions, but none said where to light it.
