Here's the completed installation. There's no room on the floor for installing a heater on the CD-22 Cruiser. I found some space between the sink and the stove in which to mount the heater . Usually they'e mounted in the rear corner, but my three burner cooking stove would have lost the use of one burner. A gas leak in this location would result in most of the heavier than air proane going down the drain and out the side of the boat, provbiding the sink is empty and the stopper is not in place. Details to follow in subsequent photos.
