Not much heat

My lpg gas heater doesn't seem to be warming us this year. Somene told me I could blow any internal dust out with a compressor but i don't have one. Is this true and can I use something else like the vacuum cleaner to **** it out? I have cleaned the rear filters

Hi Rhonda, you posted this heater as a Rinnai 1004. If this is correct the burner etc. is actually sealed from the inside of the house so no amount of blowing air would clean the actual burner. You are right to clean the filters, this should be done almost weekly during the winter if the heater is in daily use. Lack of heat could be caused by many things, sometimes I have traced it to external reasons, dodgy loft insulation for one that was actually causing the heat in the house to be lost quicker. Sometimes the weather is just colder ! At the end of the day a bit of a vacuum might make it look cleaner but you can never get in to the parts that matter like the fan/heat exchnager or burner. I started as a gas fitter in England many years ago where gas heaters are serviced at least once a year so i am a bit biased but a truly belive that if you think the unit might be under performing, get someone in to give it a not only a proper clean but also check safety and correct operating specification.

Pilot light goes out after thermostat kicks off

If it's a direct spark ignition type heater maybe that's how it's designed .When called for heat pilot open allowing gas then ignitor spark and ignite the pilot then gas valve open and allow gas through burner then unit fires off .
Once temp is met pilot valve closes and pilot out .

1999 VW Passat AC/heat doesn't work? The belt broke this summer? I was told should still blow heat even if no belt?

If you are talking about the belt for the ac compressor, yes the heater should still work.
If the blower is not working, you will need to have the blower motor checked for voltage and ground.

Have a NG unit need to convert to LP gas. wath can i do.????

Unfortunately, there is absolutely nothing you can safely do to convert it from Natural Gas to LPG.
Each unit is manufacutered and tested for the specific gas type. Attempting to change it, puts all the liability on you, if something should go wrong. There are some on this site that will tell you all you have to do, is change the pilot orifice. That's fine for a Vented heating appliance, but not a Vent-free Heater like yours. In your case, you'd need a new control valve assembly, pilot assembly, burner, etc. That alone is about the cost of a new LPG Vent-free Heater. Besides, DESA Interantional has been out of business for 3 or 4 years now. So, parts would be an issue.

Sell the heater to someone who has Natural Gas and use the proceeds toward a new LPG Vent-free Heater. Always remember and don't every forget, it's always safety first when it comes to gas appliances.

Hope this helped you and thanks for choosing FixYa.
