gas heaters???


I have an old Dearborn natural gas heater. How do you know when a heater like this is running efficiently? What I mean is, how do you make sure it's burning all the gas cleanly and not allowing any excess gas fumes to escape into the room. I don't smell anything but I just want to make sure it's OK. There's a little flap right at the valve where you can adjust the amount of air mixed with the gas. How do you know how to adjust this ? Thanks.

blue flames no yellow (shouldnt look like a candle yellow and lazy) orange may happen when you stir up dust while looking at it (normal)purchase a carbon monoxide detector there a good idea with any appliance that burns fossil fuel if flames are blue no adj is needed

Color of the flame doesn't tell you anything avout how well safely its burning.

A yellow flame can have less CO then a blue flame.

Without an annalyzer, there is no way you well be able to tell how well its burning.

No, Ken, Been is right. the flame color is a guide line but is not the total answer. A complete combustion analysis with accurate instruments and a good education in combustion science has made it possible to fine tune gas appliances the same way oil systems are adjusted.

He wasn't taking a swipe at you just putting it out there.

Really, have you seen the upswing in the sales of combustion analysers for resi use?

You could set gas up with the old Bacharach Fyrite kits also.
Just it took as long as doing a oil burner. So most companies wouldn't bother to do it.
And setting up gas by just eye balling it became the norm.

Lots of techs were taught a blue flame is a safe and efficient flame. And as long as its blue, don't worry about it.
They were taught wrong.

Now with digital CA's. Its much easier to set up a burner, weather gas or oil. Still involves some time though.

Lots of units out there with blue flames, and CO exceeding 400 PPM air free. Which is above allowable safe limits.

Fieldpiece makes heads for setting up gas(but it takes more then one head).
They also have a new meter/analzyer out, that gives a better read out then their older ones did.

If you have a Sid Harvey's near you. They probably carry all the heads for doing it. The one here does.

Thanks guys. I plan on replacing all the old gas heaters in the house so I think I'll invest in an analizer. My wife said she smelled raw gas so I did some checking. There was a small leak at the valve coming out of the wall. The little brass reducer fitting had a crack in it. I made a quick trip to Home Depot and now it's fixed.
