How do I adjust the size of the pilot light fame on my gas logs?

There is a adjustment for the pilot flame on the gas valve itself.

Gas Log Pilot Light

It may be a possibility, that the Regulator (at the source) Is set at too

great a pressure.

The spec' of the of the logburner's rating of Max Pressure and Recommended

Pressure's, should be visible on a rating plate,usually at the front- but may be

covered by a cover, possibly where the Heating setting is, (thermostat).

On this plate, It specifies, the limits of pressure,(parameters) that can be used.

The problem you have, is most Regulators, are pre-set to a factory setting,

very few have dial's or gauges, as the pressure for these appliances are set

to mB. (milli-Bars) their pressure is purposely set very Low, to maintain an

economical best setting. ( for best-efficiency).

You may have a Regulator, which has an adjustable pressure, In this case it may require 2 persons, one to view the pilot, And another to very slowly adjust the Regulator till you reach the required height of Flame that you want. (Hth).

Edit: I can't help but mention why on Earth "rejetting" would be the solution, if such a

act was done, Surely the gas would increase Its' rate of flow (see Boyle's Gas Laws),

leading to a increased in flame-length...

The fact remains, all that is required is to Decrease the gas flow, going to the Pilot,

to a level, whereupon the thermo-couple 'heats up' sufficiently, that is, to allow the main burner(s) to alight.

*Remember, too small a pilot, And the main burner will not function as intended, due to the safety features, that are built in. ie; To Prevent the flow of gas to the main burner, Just

in Case, the Burner is not Lit. ( A bad prospect, of which may lead to a gas explosion).

You don't.

The flame's length is a product of the supply pressure from the tank (which should be set by your gas provider), and the shape of the pilot tip...it is designed to create a flame the right length & shape to heat the flame sensor to a high enough temperature to keep the pilot valve open (thus enabling you to light your logs "at will") but low enough to avoid triggering the emergency shut-off solenoid...

You will likely not find any "on-line videos" explaining how to do what you want to do not just because of that, but also because if anybody DID post such a video, you could sue them for damages if you burned down your home/trailer trying to follow those instructions!

Why would you want to adjust the size of the pilot flame, it should have been set correctly on insta llation and maybe needs a service as it may actually be blocked.

needs to be rejetted. let me explain further since some of the others are giving all kinds of weird answers. Rejetting refers to the little piece right where the flame burns. I think you need one with a smaller hole in it. Smaller hole, uses less gas coming out. There is a chance you do need a lower pressure setting, but I doubt it.

There is an adjustment screw on the Gas valve, but you need to have a manometer to set it correctly

pilot is approx. 3" to31/2 long need to tighten screw to cut gas flow to what length not sure
