I have a Intertherm Model,MMHB 090ABHR-01 furnace.The Ignition control is a UT 626421.I want to upgrade the silicone carbide ignitor to nitrate.I do understand that because nitrate is much denser then carbide.They will not sense for flame requiring the addition of a flame rod.Does the 626421 have provision for adding a flame rod?If not.Is there a compatiable replacement for the 626421 that does. Thanks.

Has anyone had an occurrence of a Laser 730 or 731 over firing?
The top of the heat chamber and the heat exchanger glow red on high when this occurs....
