Question about Rinnai Toyostove Direct Vent Heater: Toyostove Laser 73 Shipping

2 Answers

Toyostove L-73 I know that the new #2 Diesel is basically the same as K-1 Kerosene. Has anyone tried burning #2 Diesel instead of kerosene, seeing that it's cheaper? If so, any luck?

#1 and #2 are not the same at all. Toyo Laser 73 heaters should only use #1 home heating fuel or Water Clear Kerosene. If you burn #2 in your Laser 73 it will soot up in less than a week. It is a disaster, do not do it!!!
The difference between the fuels is the amount of carbon in them. # 2 has a lot of carbon and therefore more BTU's of heat per pound than # 1. All that carbon will end up on the burner, blower and in the heat exchanger. It will be the dirtiest job you have ever done.

I have used #2 in the summer. I have been told the difference between 1 and 2 is 1 has an additive so it won't free. I would use oil meant to be used as heating oil because it should be lower in sulfer.

Is it allright to burn part deisel with kerosine in a Toyo laser ignited heating stove?

Only if you want to stink up the house (more than just what the kerosene does) and don't mind dealing with a little soot on the walls and ceiling.

I wouldn't. But the choice is yours to make.

hope this helped you in some way. Please let me know. Thanks.

Laser 72

Your manufacturer, Toyotomiusa, recommends that you tighten all the joints on the fuel line. Your owner's manual CLICK HERE contains detailed drawings showing the location of all parts, including the fuel injector. Your unit will need to be serviced by a qualified technician if you have tightened the connectors and still smell kerosene or find wet spots under your heater. It should not leak or smell of kerosene. If you're smelling kerosene, you should not operate the unit, because the leak may cause a fire.

Hello and thanks in advance for any replies! :) We have not used our Laser 73 for close to 5 years. Tank was empty so we had it filled and new filter installed at the tank. I cleaned the screen at the sump...

That heat tube is the ignitor it gets real hot for a minuet then the kerosene starts pumping in and it flames up from the hot tube. I would expect that kerosene is not going in to the burn pot. the kerosene valve control will make a ticking pumping sound about 1 minuet after the vent fans start. within seconds a flame should appear. If you remove the screen and open your line or tank valve kerosene should flow out of it. hopefully you installed a line valve just before the going in to the heater. I loved my laser 73 about 10 years old. but kerosene at 3.50 a gallon for the clear stuff made me install a ground source system. I keep it as a back up running it once a month for 1/2 hour. dave

Yoyostove laser 73 ee-2 keeps coming up which i know is missed ignition,but after a few times of missing ignition the k-1 leaks from the bottom of the heater what needs to be done about this problem?

Sounds like your igniter may have burned out. You can test the igniter with an ohmmeter. You can also check for voltage on the circuit board where the igniter connects. Don't try to start it again until you check the igniter because unburnt kerosene will just keep building up in the burner. Let me know if you need more help.

Can you use diesel instead of kerosene in ready heaters?

No - diesel fuel is NOT the same as kerosene. Kerosene is #1, regular diesel is #2. They are not interchangeable.

Getting code EE 2 on a laser 73 toyostove that runs on kerosene

EE 2 usually has to do with the fuel. Does the heater make a loud ticking or thumping sound? That's the sound the fuel pump makes when its not getting any fuel. Check your filter, check the strainer in the fuel sump. Depending on how cold it is any water in the fuel line could be frozen blocking the fuel flow. You might also check the flame rod for soot. It can be cleaned with some steel wool.(

Do i need to replace filter if i have been using kerosene and want to switch to diesel

No, the kerosene is number 1 fuel oil and Diesel is number 2. No.2 is a heavier fuel with more BTU's than the kerosene. After you have burned the diesel for awhile, you may want to change the filter. If you have trouble getting the diesel to burn, mix it with 25% kerosene and it will flow and go through the nozzle easier

Ok we were given a laser 73 and we have checked and there is kerosene reaching the heater but it wont lite what could i do

Check to see if Igniter is working (Dont touch)
just feel close to it, should be warm and you should see a glow inside the peep window.
Ask about service history It may be time to get it fully serviced
Good luck
