Propex Heater probs

[Zcat7]

Since my bus came back from a refurb my Propex heater doesn't seem to deliver the same amount of heat. It blows at the same rate but the air is cooler, kind of luke-warm.

It didn't run for around a year while the bus was being refurbed but was always installed, positioned under the rear seat although exposed as the cushions etc were removed. Could it be that overspray got into it or something like that (the idiot that resprayed the bus managed to cover everything else inside so why not the Propex interior...).

Does anyone know of any maintenance routines I vould do before going to Propex themselves (there was nothing helpful in their FAQs)?

Have you checked that the inlet/exhaust pipework is clear and undamaged.

I know the flexi pipes are good because I had them off at one point and repaired them (one was split). I will definitely give them a once over, especially further up into the body of the unit..
