I have an MPI 41 Kerosene (K-1) monitor heating my home. Every time the monitor starts it gives off an intense smell of Kerosene. It lasts about 4-5 minutes after starting and then the smell seems to disipate, or perhaps it hasn't and I don't notice b/c I've left the room. It's really potent!! Can anyone offer advice or help on this issue?? Thanks!! :-)

Here is some information and your Service Manual with a Troubleshooting section.

It sounds like there may be an issue with the circuit board on your MPI monitor 41 kerosene heater. Based on your description, it appears that you've recently replaced the circuit board, but you're not able to get power to the front panel, despite power showing in the wiring.
There could be multiple reasons for this, and it is essential to investigate further. Here are some things you can check next:

• Make sure that all connections are secure and properly connected
• Make sure that the circuit board is the correct one for your heater model
• Check the wiring, it could be loose or damaged
• Check the fuses, they might have blown
• Check the thermostat, it could be faulty or not connected properly.

If you have checked all these things and the issue persists, it's best to call for professional help as it may require specialized knowledge and skills to troubleshoot and fix the problem. It's important to note that working on heating appliances can be dangerous, and only qualified and licensed personnel should work on them.

possible bad ignitor

Do you see any flames before the heater cuts off? If not, check the igniter first. You can check it with an ohmmeter or with a clamp on ammeter. If using an ohmmeter, the igniter resistance should be between 10 - 20 ohms. If using a clamp-on ammeter, clip around just 1 igniter lead and you should get 2 -4 amps.
Does the fuel pump start making a thumping noise before the heater cuts off? It makes this sound when it isn't getting any fuel to it. Check your fuel filter and fuel strainer. Be sure to shut off the kerosene before checking either.
If you do see flames before it cuts off, you need to check the flame rod. Clean it with some steelwool or emory cloth. The flame rod is located next to the window on the combustion chamber and has 1 wire going to it. Unplug the heater before checking.
If this doesn't help, let me know what you have found and I can give you more info.

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.

Does it smell like raw kerosene or exhaust. If it smells like kerosene it sounds like you may have a fuel leak. If you can remove the grill, look inside and check for any kerosene in the bottom and in the tray under the heater. You should also check your fuel line for leaks. If it smells like exhaust look inside and on back of the heater for any black soot marks. There are a couple of o-rings, 1 in the exhaust connection in back of the heater and 1 in the flue pipe where the exhaust from the heater connects. There's also several gaskets in the combustion chamber that could be leaking. Hope this helps. If you need any more info, you can send me an email ([email protected]).

You need to use pure kerosene do not use died or color kerosene it depletes the wick faster and causes a distinct odor. Pure kerosene should be clear.
