I NEED A DIRECTION FOR A HOT WATER HEATER FOR A NEW RV....THE INSTANT TANKLESS VARIETY IS NECESSARY THIS TIME.....I HATE THE IDEA OF PROPANE-BUT MIGHT HAVE TO GO THAT ROUTE-THOUGH IT WILL BE INSTALLED OUTSIDE OF THE RV....HOW ABOUT AN ELECTRIC UNITE ANY ONE KNOW ABOUT SUCH THINGS I CAN HAVE IT INSIDE THEN!....geofkaye-[no I'm not yelling-my typing just sucks and I have learned not to look at the screen-but when i check back I'm too far along and too lazy to retype the whole thing....Gods forgive me]
