## Questions & Answers

**Q: Does this assembly unit fit heat and Glo model number SL 36?**
A: Assuming you are natural gas, and you have the Robertshaw valve, yes. If you have the SIT valve then the pilot assembly is 571-510a.

**Q: Flame intermittently goes out when activated from wall switch. Stays on from internal rocker switch. Will this part resolve?**
A: If wire run to wall switch is too long and/or has high resistance the thermopile may not be able to generate enough voltage to overcome the resistance.  Check voltage at gas valve (will be in millivolts) and compare to spec for the gas valve.

**Q: Is this appropriate for a 20 year old heat-n-glo model # sl-750-trs-c  serial # sl 75trscn ?**
A: Yes, that is what we have, my husband installed it and it works fine.

**Q: Will this work with heat & glo sl 950- tr-ipi ?**
A: It worked on a Heat N Glo AT Grand model, if it has a standing pilot you should be good.
