Master Troubleshooting & Diagnostics Matrix
| Error Code / Indicator | Symptom / Meaning | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|
1 Flash | 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: Gas lockouts must be cleared by turning the selector knob from gas on (flame) position to off position then back to the on position. The complete sequence of switch movements must be completed within 2.5 seconds for a lockout to be successfully cleared. Lockouts can also be cleared by switching to the 'fan only' position and then back to 'on' within this 2.5 second period. | DIY Safe |
2 Flashes | 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: Gas lockouts must be cleared by turning the selector knob from gas on (flame) position to off position then back to the on position. The complete sequence of switch movements must be completed within 2.5 seconds for a lockout to be successfully cleared. Lockouts can also be cleared by switching to the 'fan only' position and then back to 'on' within this 2.5 second period. | DIY Safe |
3 Flashes | 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: Gas lockouts must be cleared by turning the selector knob from gas on (flame) position to off position then back to the on position. The complete sequence of switch movements must be completed within 2.5 seconds for a lockout to be successfully cleared. Lockouts can also be cleared by switching to the 'fan only' position and then back to 'on' within this 2.5 second period. | DIY Safe |
4 Flashes | Combustion air fault | Check combustion air inlet flue and exhaust flue for blockages. | DIY Safe |
5 Flashes | Other/internal fault | Attempt to clear lockout as shown below: Gas lockouts must be cleared by turning the selector knob from gas on (flame) position to off position then back to the on position. The complete sequence of switch movements must be completed within 2.5 seconds for a lockout to be successfully cleared. Lockouts can also be cleared by switching to the 'fan only' position and then back to 'on' within this 2.5 second period. If this fails, contact a Propex Approved Service Centre / Technician. | DIY Check / Tech Fallback |
Frequently Asked Questions
Q: Can the heater be mounted vertically?
The heater must not be mounted vertically on its nose or end or upside down but on one of its sides is not a problem. Remember when mounting the unit you should ensure you can still maintain access to the electronics cover and gas connections
Q: Where can the heater be fitted?
Most installations are mounted in a bedbox or locker. External installation is not recommended unless using the appropriate mounting box. However the HS2211 is designed to be fitted externally.
Q: How noisy is the heater?
There is very little burner noise from the heater itself. However, there will be some noise from the blown hot air similar to that of a small domestic fan heater.
Q: Can the heaters be used while vehicles are moving?
Yes, a vehicle in motion flue terminal is available and the heater should be installed and operated in compliance with the relevant regulatory requirements. Use of the the correct VIM bracket ensure compliance with the vehicle in motion test regime.
Q: What length of exhaust flue pipe can be fitted?
Total combined length must not exceed 4 meters and the inlet pipe should be slightly longer than the exhaust to balance the burner.
Q: How many outlets can you put on the Heatsource HS2000, HS2000E and HS2211?
The maximum recommended is 3, providing the total combined length of ducting is no longer than 5 metres and the maximum length to the first outlet should not exceed 1.5m.
Q: What is the electrical consumption?
1.6amps on 12v
Q: How much do they cost?
From as little as £496 for a Heatsource 2000 complete with a single outlet vehicle fitting kit and thermostat.
