I have an LP gas fireplace that is putting soot everywhere. I have cleaned it before the summertime this year. How can I be sure the fireplace will not blacken the whole room and everything in it as

There are two things that control flame height gas volume and air volume. Some fireplaces have a flame control knob on the gas valvd to adjust flame height. Air volume is controlled by an air shutter usually located where the main gas orifice enters the burner. There is usually a small cover that will need to be removed to access the shutter. Closing the shutter will cause the flames to become taller and more yellow colored. Closing the shutter too far will cause sooting problems so great care should be taken in adjusting this shutter.As a rule, L.P. gas fireplaces do not have as high of a flame as natural gas unit do.
Hope this helps

Normally soot is from a range that hasn't been converted for the gas type, like natural or propane. It may be set up for natural when you're on propane or visa versa. Has this range ever worked properly without sooting?

Is a Vented or Vent-free gas fireplace? I really suspect it's Vent-free (ventless) as a vented unit, unless the direct vent is clogged exhaust everything, including 85% of the heat out side.

Here are the things that will cause a Vent-free Gas Fireplace to soot.

• Not having the fireplace cleaned and serviced, at least annually by a qualified technician.
• Misplaced logs that impinge the main burner flames.
• Running a ceiling fan at the wrong speed and in the wrong direction while fireplace is burning.
• Burning scented candles while burning the fireplace.
• Low Gas Pressure to the burner.
  

Here are the solutions to the above listed causes:

• Have the fireplace cleaned and serviced.
• Check your Owners Manual concerning the proper placement of each log,
• Run the ceiling fan Counter Clockwise and at the slowest speed. The fan on the side of the switch should be in the UP position for Winter and Down for Summer.
• Scented candles soot any way. Add the warm moist heat of the Gas Fireplace and they'll soot 50 times worse. The scent is not natural, it has an alcohol base like after shave & cologne. Stop burning scented candles. It has been proven that they greatly contribute to indoor air pollution.
• Low gas pressure causes incomplete combustion, which causes the burner to soot. Have it checked by your propane provider.

Based on my 15 years in the hearth and home business and having sold and installed hundreds of these appliances, I am will to bet, it's a cleaning and servicing issue or misplaced logs.

Hope this helps you solve your sooting problem. I woud really like to know how it works out for you.

Soot is a sign of too much gas and not enough air. Have your propane supplier make proper addjustments.

Check to make sure the orifices and regulator was changed properly and open the air shutters.

you have a problem with combustion.unit is not burning properly you should turn unit off and call a pro the life you save may be your own

Remove the burner and clean all holes ,typically at the end of the burner is a cheep sheet metal valve.This valve adjusts the air to gas mixture by rotating it to increase or decrease the combustible air intake.Air must be sucked into the burner as natural gas is injected into it, this makes for a clean flame,The flame should be blue with small yellow tips.If the flame is long and yellow and sooty increase the air intake on the burner valve.

Thanks for your question,
your problem is either impingement on your log set, or a product of incomplete combustion, if you notice soot on your logs, then you will need to take them out, clean them, and reinstall them as to not have the flame touching them, you will need to clean the burners as well, make sure nothing is laying across the burners, as this too will cause sooting, as far as incomplete combustion, was this model a natural gas converted to propane or the other way around ? if so who ever converted it, did they adjust the gas valve according to specs? improper adjustment will cause sooting or hooking up a natural gas unit to propane will do this too, I will recommend using (Rutland White Off) to remove any soot from your glass, it works fantastic for this ! any ace hardware will carry it, please do not use windex or any other cleaner on the glass as it will more than likely leave a rainbow affect on your glass once the glass heats up, hope this was helpful to ya, please rate this solution, thanks agai

burners burning yellow , in complete combustion , blocked air ways to burner , it needs a service soon as poss

well its my experience that ranges don't come lpg they are all made natural gas but you convert them to lpg after purchase now if the lpg conversion isn't done properly then they soot like crazy proper lpg converson is to change the spuds on the burners and to turn the orifice over in the pressure regulator do you still have your owners manuel if so consult it on converting gas range to lp then check to see if every thing was done right on the pressure regulater there is a square cap you take it off and there is a round part that on one side says lp on the other says ng this changes the pressure that the regulator as ng and lp operates at different pressures and the regulator has to be set for what you using like i said im not familiar with your brand or model but i do know the problem if the range did come ng then you need to make sure the conversion most ranges aren't lp because there is not that big a market for it read the plate on the back will tell you if it was made ng or lp serial plate on front may say also most of the time it is beside the bottom drawer on the range
