Wave Heater installation

Has anyone installed a Wave Heater in their coach?

I am looking to install one, as I do most of my camping without any hook-ups.
The furnace uses too much power to run all night, and the Wave Heater uses none.

I am looking for the location to get the gas to the heater?
From the water heater? the over/range?, is there a "block" or "manifold" under the cabinets somewhere? or is there a better spot?

I've done a couple of these installs on other RV's.

Thanks for all of everyone's assistance.

Later, Jeff.

No, there is no manifold or spare port. Assuming you wish to make the gas connection downstream of the LP regulator, there is black pipe in the basement going to the fridge and propane furnace. (painted white of course) This is where I made the connection for our outside BBQ QD.
There is a 1/2" tee at the end of that pipe about under the furnace in the basement. (just behind the vacuum)
I removed the tee and installed a four way connection. You could do the same and leave everything else intact, or remove the furnace connection from the original tee and run that to the Wave. I guess it depends where you intend to install the Wave....
Good luck.

I would think the juntion block for propane lines would be outside the living quarters.

By code, the only connection inside would be for the stove.
Water heater and fridge are out in vented to outside spaces.

My furnace uses 7 amps when running. It runs about 1/2 the time in cold weather.
That's 3 1/2 AHs. A single 100 AH battery will run that for 20 hours, if nothing else is on.

So what I have found under the sink is, two flexible lines that come in for the range/oven and the water heater.

It looks like a very simple connection change. There is a male/male coupler that connects the flexible line to the hard line for each of these. I am going to replace the straight coupler with a tee coupler and plumb the heater to the new added port. This way, then flexed portion of the line (that is needed for the pop out) will not be disturbed. Only about three feet of new line will be needed to connect the heater to the new port.

Thanks for all of the help, again.

I t'ed off from the furnace, and put a threaded valve there to connect a hose to the heater. That way I can put the heater out of the way under the dinette table when not in use without the hose going across the floor.

I had a Wave heater before. I would not recommend one. Not so much heat, and the pads give out in a couple of years and are not replaceable. I like my HearthRite ceramic brick heater. Some people like Blue Flame heaters better.
