Do NG barbecue units require a pressure regulator?
Thank you,
Seamus J. Wilson
Yes indeed.
Almost all natural gas and LP appliances utilize a seperate regulator at
(or built into) the unit, including stoves, cooktops and BBQ's. Typical
settings are from 3.5" to 5" water column on the outlet side. The
meter/regulator does not step down this far. If you don't use one, the
flame will be blowing and lifting off, making for a cold flame with a
high
level of flue by-products such as CO.
Check with the unit manufacturer for proper manifold settings for their
particular burner.

To clarify,
The regulator on the side of the house, at the meter or wellhead,
whichever
you have, needs to be set higher. The reason is because enough pressure
must be available to push the gas through the house piping without
friction
loss. The reason it is stepped down at the house is to bring it down to a
much safer level should a leak occur inside. Typical settings for this
regulator are around 14"-15" w.c. unless you have a CSST piping system
inside, in which case it is likely set around 2#. Much too high for
individual appliance use.

To further clarify, you don't know what you're talking about. I just
did a conversion from propane to natural gas on a Charmglow outdoor
grill using the Charmglow conversion kit.
The conversion consists of:
A - Removing the propane hose and regulator.
B - Replacing that with the natural gas hose, which has no regulator
C - Removing the tips of the burners, which makes the orrifice larger
D - Changing the bezels behind the burner knobs. The new bezel has a
different stop that limits how far it can be turned in the low
direction.
Don't I??

You read the post. I said check with your own individual manufacturer for
their recommendations, so whats the problem?
I would be willing to bet you did'nt actually check your house pressure.
You can see that Charmglow is depending on your house line pressure to be
only 7" water column. But you have no idea. You just know it seemed to
work and that's good enough for you. Unfortunately pros can't afford to
guess and let someone cash in that multimillion dollar liabilty insurance
policy that they keep on their companies, so they check things out little
more thouroghly. BTW, you also know that the Charmglow/Home Depot marriage
isn't exactly producing the most satisfied customers, don't you?
