Re: heater

[STEP 1] Check air pressure with proper gage
[A] Adjust air pressure to correct specs as shown in the manual
[B] If that doesn't show anything follow STEP 2
[STEP 2] Take the rear plate off by the air adjustment that has 4-5/16" bolts. Start the heater and see if you have air coming out the vent hole on the left side under the top bolt.
[A] If you do the air pressure gage needs to be cleaned. keep plate off and blow air through with an air line.
[B] If that doesn't blow air through the vent hole follow STEP 3
[STEP 3] Take the next plate off that has a bunch of 5/16" bolts.
Carefully pull that off and inspect that plate.
[A] If that plate has gouge marks look at the manual for sanding proceedures and follow those carefully.
[B] If it still doesn't work call mfg.

Re: heater

Check the fuel line that goes into the tank.If it look the least bit cracked, replace it. It will suck air instead of fuel

Re: heater

First check filters. Then check pump pressure. Then nozzle for debri.
Starting points anyway.

I have 2 heaters that will run out of fuel when tank is still half full

What size LP tank are you using? If you are running (2) 175,000 btu heaters on a tank that is too small, especially in this cold weather, it will not have enough vaporization to keep up with demand. This will cause the outside of the tank to frost up and the pressure inside will be too low to run the heaters. You need more wet surface area, i.e. a bigger tank or just manifold 2 tanks together.

Are you using old fuel from last year? If so, drain/clean tank. Check/replace fuel filter. Refuel with fresh fuel & test again.

I have a Toyo Lazer 30. Often times it doesn't run for a few days (I also use wood heat). So then when I go to start it up (after a few days) or if the thermostat tells it to start, it might run for a few...

Ticking is a sign the heater is not getting anough fuel to keep running. Check your manual and see if there is a valve inside your heater that controls fuel flow. Make sure it is open all the way. Also check to see if you have the valve on your fuel tank open wide enough to allow fuel to flow like it should. Another tip. Instead of turning your heater off all the way when you are using wood heat, why not just turn the temp on the heater lower then you know your home would get to with wood heat running. Adjust the temp to where you need it when you want the heater to run. (That way your heater stays primed.) The heater doesn't draw that much electricity. ;)

Hope I have helped.

Pro 110, runs 10 min., blows white smoke ,shuts off

the first thing you need to do is go back to useing K1 kerosene, diesel fuel not only burns dirty but also has a tendency to gel up in cold weather which could be makeing it hard for the heater to draw the proper amount of fuel. To reset the pressure you will need a gage, it should run at about 6-7 psi. you can order a pressure gage from mr. heater online, they are by far the cheapest I have found as they are the actual manufacturer or call 1-800-251-0001
