I never used any sealers, but you must use high quality clamps, stainless "mikalor" are very good, they have a saddle that clamps evenly around the entire fitting making a gas tight seal.
the cheap screw clamps that are supplied with some heaters are not fit for purpose, except for the hot air side.
my appearance is down to me, my attitude is down to you.
Hi Adrian yes that would be ok , Why do you need a sealant not usually needed, there should be a tight fit between hose and hull fitting with a clamp there to stop it coming of, there isn't any pressure as exhaust gas is just blowing through to atmosphere the hose needs to point/slope downwards at the fitting to stop/allow water to run outside and not back to heater.
