Room heater on Duetto

Hi there.  I've just bought a 1998 Duetto on a Ford Transit base and knew the Propex space heater didn't work but would like to get it fixed if possible.  When I start the heater I get a red light on the panel and of course nothing happens.  Does anyone have any idea of what might be wrong?  I'm not at all 'handy' so would need to get someone to do the work if it's complex, so does anyone know if there's any place to fix it in Cornwall?
Thanks.

Firstly welcome. 
You need to tell us if it's a Carver P4 heater or a Propex. Unfortunately on a 1998 it could be either. There will probably be a name on the heater control panel.

It's a Propex.  I've edited my post to show that.

This is the instructions for troubleshooting the Propex

TROUBLESHOOTING 
The heater is equipped with an electronic diagnostic system which will detect fault conditions ranging from poor 
gas or d.c. supply to internal heater malfunctions. In the unlikely event of a failure, the red light on the control 
panel will flash a number of times, pause, and repeat until switched off. Count the number of flashes and refer to 
the table below. 
Number 
of flashes Fault Remedy 
1 No flame detected 
Check gas supply making sure there is gas in the bottle and no blockage in the 
gas line. Ensure propane is used at temperatures below +5°C. Clear lockout as 
described below. 
2 Overheat 
Check the air ducts and vents are not blocked or restricted. We recommend 
that you wait at least 5 to 10 minutes to allow the heater to cool before 
clearing lockout as described below. 
3 Low/high supply 
voltage 
Minimum operating voltage is 10V, maximum is 15V, when measured at the 
heater. Check battery voltage. If between 10V and 15V, check connections 
between heater and battery. Check alternator or external battery charging. 
Clear lockout as described below. 
4 Combustion air 
fault 
Check combustion air inlet flue and exhaust flue for blockages. 
5 Other/internal fault 
Attempt to clear lockout as shown below. If this fails, contact a Propex 
Approved Service Centre / Technician.

That's great, many thanks.
