I have a gas outdoor grill hooked to my home gas line here in Southern
California.

This winter my grill is not heating near enough. I can cook on it but
takes some time.

I took out the lava bricks and cleaned everything up. Burner is fine
and all holes open. Flame comes out even but low.

Years back I did put in new valves as its a Sears and easy to get
parts and install, but have been holding off.

Seems that this has occurred since the gas company came along and
installed a new meter to replace the original one some 45 years old.
So I am wondering if this new meter has a lower flow rate.

I have two gas furnaces, upstairs and downstairs and gas water
heater and they function fine.

Also, I cook in evening at sundown just went gas use would be high
with everyone's cooking and furnaces kicking in.

So I was holding off doing an overhaul to see if this gets better in
summer.

Any one have an opinion about the new meter having a lower flow
rate???????

Or if I overhaul should I put in different gas jets to get better flow?

I am going to assume that it once worked OK and nothing was done that
would change that. Remember that propane and NG require different parts and
if you have the wrong parts (I can't remember which way) it could cause this
problem.

You may want to take a careful look at all the tubes where air or gas or
both pass. Some spiders just love to make their homes in there and can
block things up. It is not good for the spiders either. I have head of
some sort of prevention, (stainless steel wool?)

Probably not.

No. Or maybe. Call your gas supplier. The technician can likely give
you a helpful opinion on modifying the grill.The big clue is the low
flame, indicating that the normal flow is compromised by either low
pressure (adjustable at the meter) or an undersized or otherwise
faulty gas line. A malfunctioning shutoff valve could cripple flow,
for example. One common diagnostic technique is the familiar
'substitute known good part' that you see in every auto repair manual.
Borrow a good grill from a friend and try it out - the results will be
very informative. HTH

In my area, spiders somehow manage to plug the gas orifices in my outdoor
grill with their web material. The low flame creates the impression of low
gas pressure, but the real issue is actually an obstruction. In my grill,
the solution is to take apart the jets and clean the orifices with a
toothpick.
