Can anyone tell me how to work a Propex heater?
When I put it on cold it blows cold air, but when I switch to hot it doesn't do anything.

I haven't a clue. I looked on the Propex site, you can download manuals, but I can't see a number on the control and the heater itself is hidden below the wardrobe where I can't get to it.
The control is a black box with "Propex Heating" written on it, about 3 ins x 2.5 ins x 1 in thick; it has a rocker switch - left for a flame (presumably hot) and right for a squiggly symbol (blows cold air so presumably for hot weather) and it has a dial with a flame on, marked 1 - 5.
I've only ever had Carvers before.

I read through that and it looked like it might be the one, so I tried it. Everything went fine, but the fan cut out after a minute or so and no hot air, even though the lights were steady so no fault indicated.
I'm having problems with the fridge as well, won't work on gas but great on EHU.

I'm having problems with the fridge as well, won't work on gas but great on EHU. Hi Caz, can't help you with the heating, but have you tried turning the fridge upside down for half an hour, then righting it, leave for another half hour for the gas to settle then it will probably light. The gas pipes can get 'dry' and if you tip it upside down the liquid gas re-wets the pipes. Did this with mine when I first got it and it's worked ever since. Or it could be that it hasn't been used in a long time, it usually takes me about 5-10 minutes of cursing before mine lights if I haven't used it for a while! It takes long than you think for the gas to come through to the ignition point, which is right at the back on mine. Good luck! |

This might sound a bit obvious, but could there be a gas tap somewhere that's cutting off the supply to your fridge and Propex, and just needs to be turned on?!?

In the HS2000 instructions no flashing can indicate a thermostat fault. Not sure that makes sense as the unit seems to be purging and then giving up. Could be lack of gas or faulty igniter |

Thanks, but it can't be a problem with the liquid inside because it works fine on EHU. And anyway I can't think of a way to turn the van upside down. ;D |

Keith Thanks, but both the taps are turned on, and gas is getting to the fridge because it's burning with a nice steady blue flame and heat is coming out of the vent, it just isn't cooling the fridge. I left it on for about 5 hours but nothing happened. On EHU it was freezing the ice box within half an hour. |

Could be lack of gas or faulty igniter Thanks, I think I need an engineer then. Spent up on getting the van sorted so the internals will have to wait, I'll just have to make sure I always have EHU for the time being. |

Hi Caz have you ever had it going ? because it really sounds like there is no gas present or the main burner is off, best wishes Brian

Check the gas supply is turned on and that the battery voltage is correct (see
specifications).
Rotate the thermostat dial fully anti-clockwise and push the 3 position switch to the
left. The red power light should illuminate.
Rotate the thermostat dial until the green light illuminates. After 3 seconds the
heater motor will start and ignition should occur after a 30 second pre-cycle.
Select the desired temperature setting by adjusting the dial on the thermostat. The
heater will then cycle on and off to maintain that temperature.
When the set temperature is reached the green light will go out and the heater will
start its post purge cycle. When the motor switches off, the red heater light will dim
indicating that the heater is on standby.
The 3 position switch is depressed on the right, the green LED will illuminate and
the fan will blow cold air continuously.
sequence of operation:
Switch on
Heater motor starts
30 second pre-purge to clear gases from heat exchanger
Gas valve opens
Spark generator operates
Heater lights and runs
Temperature reaches thermostat setting
Heater switches off
First Purge - approx. 2mins depending on heat exchanger temperature
Temperature drops
Cycle repeated
MAINTE if you can follow this it should help Brian

No, I've only had him a couple of weeks (and he's spent most of that time in the garage, where he is again today  ) The previous owner said it worked, but then she would! Those instructions are the same as the ones someone gave me a link to above. Hoping to get him back today and go away this weekend so will have another try at getting the heating working. No big deal if not, I'll just use a fan heater if it gets cold, but it would be nice to know it works in case of EHU tripping. Ditto the fridge on gas. I usually have EHU over winter months, but you know how unreliable some sites EHUs can be esp in winter when everyone wants their heating on.  |

Could be lack of gas or faulty igniter Hi Caz, hope your van is sorted now, it has just dawned on me what the Propex instructions are on about. It has a micro-processor and it's little logical brain is thinking that things are hot enough and it is not switching on the gas. At the moment the ambient temp is still quite high, the thermostat may not kick in until things get colder. Given luck, when you need the heater it may fire up Derek |

Caz,
I had your issue a while back. There were 2 causes...
I found that sometimes it was because gas wasn't getting to the heater, if you don't use it for a while you may need to flick the rocker switch a couple of times before the gas travels through the pipes after being switched on.
The second cause was low voltage coming off the battery, I think my battery may be near the end of its life, it's good for lights still but i'm wondering if it has fallen below the threshold for being able to work the heater.
I'd try turning any gas taps you have on, running the engine and flicking the rocker switch a few times. If it all suddenly starts working with hot air you should be able to turn the engine of to see if it's an electrical issue.
Thermostat should go up pretty high where you should be able to get hot air out still on a fairly warm day, mine does (not that I use it)

Hi Sloeman, thanks for that.
Low voltage could well be the problem. Had a chap here today to do a habitation service, lights are very dim as well and he tested battery - it needs a new leisure battery. I hadn't realised the battery was a problem because the lady I bought it from said she had put a new battery in - she must have meant the cab battery, not the leisure one. On the Frisky I had before, the cab battery was on the right but on this one they are the other way around, so what I thought was a newish looking leisure battery was the cab one. DOH!
So I'm getting a new leisure battery and we'll see what happens then!

Any luck?
I've just started using my heater this year, took me 8 attempts flicking the rocker switch before it lit. Coupled with my troubles starting I think I may need to replace both my batteries.
