Troverman, the needed warm up time you describe is a bit unusual. Sounds like something is not right. Before you start modifying the system, I would recommend going over the operators manual and double checking the directions for your cab system, then going to the wsm and its troubleshooting sections, and then call the dealer. At 14 hours it is still under warranty, and it may be something simple.
My open station L3560 reaches operating temp much faster than that, more like 10 min, and my cabbed B2650 also puts out heat much sooner. Granted I am generally bundled up just to get from house to barn, but I start to shed gloves and hat pretty fast in the 2650.
