the easiest way is to remove the pipes to it from engine bay and use a copper pipe to bridge the pipes, so you will need to cut the ends off and use some jubiees on the pipes to secure it to the copper pipe standard house hold size copper pipe, if you do need to cut ends off make sure you leave and inch and a half on them so you can fix them back on when the heater core is replaced or fixed. just to recommend i would fix the core as soon as possible
The codes are "E" Codes. an E13 is no fuel. E-14 means flame rod malfunction. Unplug the heater then reconnect, this will reset the heater. Try your red prime button. Could also be the fuel pump or your fuel source feed line isn't flowing fuel.
Could be a leaking fuel injector or faulty pressure regulator. I would unplug the injectors first and see if the flooding stops. You may have to test each injector to find the defective one.
Sure is. You simply need to purchase a to 3/4" to 1/2" Male to female reducer. You didn't mention if your current gas piping is flexible copper, rigid black iron pipe or flexible stainless steel. In any event, get the one that matches your current gas piping. If all of your other gas appliances require an individual regulator, then you'll need one for the tankless water heater. If in doubt, contact your propane provider.
Hope this helped answer your question and provide a solution.
I would check all fuel lines, connections, and watch how long it takes to ignite. Kerosene heaters should atomize fuel meaning it should look like a fog not droplets, so that would point to fuel nozzle problems. That being said it should exhaust out side not in to the house, inspect the burning chamber real good for cracks or leakage? If this unit has a flue or damper make sure it has a good draft to exhaust the burnt fuel. This is purely speculation not a solution, these are things I would be looking for if it were in my home. Good luck
I just recently used a 1.5 inch thick aluminum pipe to extend the exhaust and a 2inch pvc pipe to extend the intake. I wrapped the area where the parts meet with aluminum duct tape (the good stuff) to seal any exhaust leaking out. I found a website that sold me the aluminum pipe but I was at my local home center the other day and saw that 1.5 inch think metal electrical conduit pipe would have probably worked.
I have been using this for a month now with no problem.

If you have a Monitor heater you need to figure out right
away what is making the odor. Any odor from a Monitor heater could be CO and
that is not good. Look at the back of the heater where it connects to the
exhaust. The little Z pipe should be all the way in at both the stove and the
flue pipe. Take the front cover off the heater and look at the heat exchanger.
This is the part on the right side that has either two or three chambers. Make
sure there are no cracks anywhere. Also look at the back of the unit where the
fuel connects. There should be no raw fuel any where. Beyond this you will need
to get a service guy over and have a good look.
Sal,
the gas pressure test should be done. Propane should have an outlet(heater side of the regulator)of 7 inches of water column. the inlet side has to be higher than that to supply it the proper pressure. Also the heater should have been converted to LP with proper orfices and springs
Do you hear a thumping noise on the lower right side of the unit just before it starts flashing the light bars? If so you have a fuel supply problem. If there is no thumping noise I would check the flue pipe on the outside to be sure it is clear. Lastly I would remove the copper fuel pipe from the burner and try to start the stove. If fuel comes out the pipe the pump is good. If fuel comes out I would stick a paper clip down the fuel nozzle about 3 inches, it could be blocked with carbon. If no fuel comes out the pipe, you will need to get a manual or a tech to help you out. The choices would now be fuel pump or main board, both of which are pricey so you don't want to make a mistake.
That being said, when was the last time you had the burner serviced? Mat, ring and all the gaskets involved? A Monitor 441 needs to be looked at about every 3 years to be sure you get through the heating season.
