The strange thing is that it reports no error codes. The two green LEDs always stay lit. From a control board point of view everything is operating as designed.

Thank you. This Rheem furnace has 3 wires for heating, cooling, and fan. The fan can be activated independent of the cooling or heating. I thought that was usually a standard feature for a FHA gas...

I did experiment with the thermostat months ago. I had the mechanical thermostat replaced with a programmable thermostat. The furnace behaved the same way with both thermostats.

I have the amendments for section 5 and there is nothing mentioned about water tank connections. It only amends tankless water heater temperatures.

IPC 2009 / water heater

What does the IPC 2009 call for water heater connections?

Water supply: rigid copper with dielectric unions or flex copper?
Gas supply: rigid pipe with a union or S/S flex line?

I think the 7.5v battery is the best option. If you can't find one then you could put six LM317T voltage regulators from RadioShack in parallel as a quick way to get the 7.5v and 8Amps you require....

I see how the temperature rating and ampacity works now. Since my breakers are UL rated for 60*C and 75*C wire then that is the max. temperature value I can use even with XHHW-2 90*C wire. That means...

After looking at the datasheets. It seems that the XHHW-2 would be better and is rated for up to 100 amps where as the XHHW is only 90 amps. Both are good in underground conduit.

What is the difference between XHHW and XHHW-2? It looks like they both can be in underground conduit. The -2 appears to have a higher current rating and different temperature. If they cost the same,...

Thank you. Yes, in this case it is all metal and continuous. I am surprised they allow this.
It seems like it could easily end up with a joint / connection with a large resistance and poor path. I...

The current outlet box is 21 cu in metal. So by changing from one receptacle to two receptacles should be fine with 12-2 w/g wire.

2*2.25+2*2.25+1*2.25 = 15.75 cu in.

That is what I suspected. The old conduit has the power feed and phone together and it never seemed right to me. Not to mention that the old wire is romex in the conduit. It kind of ticks me off how...
