## Questions & Answers

**Q: Does this fit the heat n glo fireplace model sl-750tv-d?**
A: if your fireplace serial# is before 0021076242 ... then this will definitely fit. if your serial# is after ... then this will probably work just fine

**Q: Will this fit a vanguard model gvc50na?**
A: I have no idea, but my guess is - probably not.  Your best bet is to dig out your owner's manual or go to the Vanguard website - and look-up the part/part # thermocouple for your fireplace, and then cross-reference that to the Amazon website.  Good luck.

**Q: Will this fit empire dvvk-3-fv innsbrook direct vent lp gas fireplace insert?**
A: Without doing any research . . . I'm almost certain the answer is no.  I've found that the interchangeability of these thermocouples is almost non-existent.  Your best bet is to check your owner's manual for the part number (in the very back) and then cross-reference that part to Amazon or a similar after market supply source.

**Q: Is this a 87D thermocouple for a Cozi furnace?**
A: The answer to this question is best received from the manufacturer.
