HELLO ALEX
OH! my god you have got me worried now . should have spoken to you first i had not thought about condensation at all
the gas fumes pass through the copper tubes and out to the open air at the top they cant get back into the chamber as it is sealed the only thing that should be able to pass around the chimmny is the warm air from the rear body at the top the copper tubes pass straight through the plate but at the bottom they are counter bored sso the tubes dont come into contact with the flame from the burner . but im going to take seriously what you say dont worry id rather be cold than dead ill test it out using a box as the vehicle body underneath the burner is a three inch hole for air so the gas fumes rise. but tonight i will look carefully at what you say many thanks vic .
