LL website question

on the LL site for the heat jacket,,does anyone know what they mean by ---"Wire the fan limit switch into the AC side of your furnace fan control".
what do they mean by AC? air conditioning or AC as in electrical?

The term AC in this instance is referring to Alternating Current, or the 115 VAC fan relay/power leads that run the fan. This makes sure that the fan runs when the stove is above the set point to pull hot air through the duct work and prevent overheating of the Hyfire.

As the directions state it is recommended that you consult an HVAC (Heating Ventilation and Air Conditioning) professional before installing your hot air jacket.

i have tried to explain this to my hvac/electricians --they dont seem to get it. Either i'm missing something in the explanation or i need new workers. . anybody out there able to supply me with a dummy version to explain the these guys what i need done?-- yea yea i know,,i'm part of the problem too but i'm not a professional.
thanks

Send me a PM with their phone number, I'll give them a call and explain it in more detail. Or PM me and I can give you my number. Either way I'm sure we can get this figured out.
