    help identify old wall-mounted gas heater

    I have this old (likely circa 1950) natural gas wall heater, and would like some help identifying the make and model. It has a thermocouple pilot which is activated by a push button at the bottom left. Please take a look at the picture and see if you recognize it. Name:  heater.JPG

    looks like a holly ,also look on the bottom plate under the gas valve to see if there is a data plate .on some of the older heaters you have to retrofit a new hydrauilc gas valve assembly if the original goes bad .

    Thanks! Does this heater look like it's venting outside? I can't tell if there's a flue going up (this is an old apartment building)

    I hope it's venting outside. Just because there's a pipe hooked to it, doesn't mean that it vents outdoors. Do you have any low level CO monitors?

    Thank you. The biggest issue is the smell which gets strongest on high setting. It could just be some organic matter burning out, but I've scheduled a free inspection with the energy company to make sure there's no gas leak or CO emission.

    The burner flames are not uniformly blue -- there's a bit of yellow there.

    Also, the edge of the metal "hood" on the standing pilot light seems to be glowing non-uniform yellow. I am not sure if this is OK, or maybe it just needs cleaning. Will wait for the inspection results.

    The flame has no relationship to how a appliance is burning. I had one the other day. Pretty blue flame that was producing over 2000ppm CO. everything looked good but it was producing deadly amounts of CO. A pretty orange/yellow flame could be burning at 0PPM CO. The only way to figure out is to test...test....test.

    I had it checked out -- all is good. They said the smell is just the old deposits/dust/etc. that needs to burn off over a couple of days.
