Pilot light seems to high

The pilot light on my Ml300EHBC seems to run to high. It flickers and and has a very distinct pressure sound to it.  FLickers mostly blue to a little orange and seems to be too large a flame.  Is there an adjustment for this?  ALso the fire seems to high in the heater at times.  All new tank, lines installed and tested by gas professional.

    The pilot light flickers and and has a very distinct pressure sound to it. Eventually the pilot light will blow out. Tech support had me try blowing out tubes and vent all to no avail. This unit in brand new and has done it since it was installed. Yea while it is still under warranty it looks like it may cost me more money to have a "Professional Installer" look at it.

There may be an adjustment screw for pilot height. you'll have to look at the valve. a pilot should have an inner cone of greenish blue color and the surrounding flame should be a deep blue no yellow or orange tips. the pilot burns pure fuel no air. the main valve does mix air with the gas in order to burn.

I have a dyna glow 18000 btu btrand new the pilot just flickers on and off won't light is it because there is too much oxygen if need adjust where is the adjustment screw at

Flickers points to lack of air you may need to clean pilot so its strong and blue . Any adjustment would be near where the pilot supply goes in the the gas valve.

I have a Procom ML300EHBC. The pilot lights, then the burner comes on but both shut off within a few minutes. I'm wondering what things would cause this.

Because you are dealing with a gas appliance I suggest be very careful.
I recommend call the gas company and have them come out and check it.

Pilot flame flickers when burners on and drops out valve

You should either do a smoke test or use a candle to check for drafts to be sure that it is not a gas pressure issue.

For (fire) safety, there is usually a thermostat that will turn off the gas if pilot light goes out.

So when you try to light the pilot you will have keep press & hold the pilot gas supply for at least 10 sec until the thermostat is heated up. Then only when the pilot light stays on continually, can you turn on the burner.

Forget about changing to a High pressure regulator!
