Out of curiosity, I copied your thread title into a google search.
The first hit was the service manual, which deals with winterizing on pages 13-14:

Thanks , I do have the manual but as many it's somewhat vague. As it doesn't say anything about using the aqua hot for just heating with the RV anti freeze in the water lines. I'm afraid it might expand too much or cause problems.
I decided just to get a couple eletric heaters to use.
Thanks to all for the replies
You can use a Aqua Hot for FURNACE operation after it is winterized. There is no danger or damage than can happen when winterized. There is nothing to "expand". Doug
