## Questions & Answers

**Q: I have a Baxi Duotec 24 Combi ERP ..will this fit ?  Does the boiler require draining to fit it ? Can it be done DIY**
A: I have a friend (gas safe ) who  fit this thermistor for me . It was a 10 minute task and boiler did not need draining as the thermistor fits in a pocket . As for whether it could be done as a diy job I would say probably yes for someone with good E/I knowledge. May friend did advise the task to be under taken by gas safe engineer to comply with all regs etc.

**Q: Thread size?**
A: HI
The thread size is 1/8"

**Q: Thread size?**
A: Think it was 1/4 bsp

**Q: Does this product need a washer/gasket?  If so, which one?**
A: Hi, If you buy a Genuine one  you will need a washer as Baxi supply them as separate items.  The Baxi Part Number for the washer is 248069, It used to be a fibre washer but they now sell a copper washer.  If you buy a compatible one it will come with either a fibre washer or an O'Ring.  It does need a seal, but it can be a fibre / copper washer or an O'Ring, though engineers I know tend to use PTFE tape to make the seal
