What it is
The Vaillant 049749 is a throttle jet, listed by the manufacturer as a pre-nozzle restrictor sized 2 x 3.25 mm for LPG applications. It meters gas flow into the burner circuit on Vaillant Thermocompact and Turbomax appliances. The part supersedes the earlier code 049637.
Signs this part needs replacing
- Gas rate at the meter falls outside the figure stated for the appliance on LPG
- Combustion readings drift or cannot be set within the required range
- Sooting, discolouration or flame lift at the burner
- Rough or repeated ignition faults traced to the gas inlet side
- The restrictor is blocked, damaged or has been removed and not refitted
Before you order
- Confirm the appliance is running on LPG, as this restrictor is sized for LPG only
- Check the model and variant against the fit list above, including the R revision
- Inspect the existing restrictor and compare its marked size with 2 x 3.25 mm
- Note that 049749 replaces the earlier code 049637
