Explosive Post… Propane Grill

[timvasqz]

Bill that's the grill I use or a close China reproduction of it I got at Lowes.
I had an industrial hose shop (the Hoseman Riverside,CA) build the hose long
enough to move the grill to a bench 8 feet away from the bus. I got the fitting
to match the bus outlet from http://www.mbsturgis.com/ I am not sure your
configuration is the same. I use the regulator that came with the appliance
which I can continue to run off of a bottle if I want to place the grill more
remote to the bus.
I can shut off the gas at the fitting outlet prior to the appliance regulator
and the grill will burn for another 10 min at full tilt. if I dont burn it off
gas pressure, there is a big freeze as I let the pressure out during disconnect.
My problem with leaving the hooked up grill in the bay is there is no vent in
the floor for falling gas.

fit in front basement of our FC, gets real hot fast and cools off fast too and
temp is easy to control and cleans up nicely. Although its not heavy duty, its
beefy enough (pun intended).

many off the shelf grills, this unit comes equipped with a high-pressure
regulator and in this case the control is on the regulator itself. I wanted to
get a hose and fittings to use with the coach's dedicated Bar-B-Q valve. I just
thought it would be a simple thing to do.

propane system to accommodate the grill because they were not getting sufficient

making a big deal out of something that is no big deal, but I ain't taking
chances with propane gas NO SIR!

from the coach and learned that the coach is set up with a low-pressure
regulator (6 ounces -10.5 inches water column). Apparently this is an industry
standard for large RV systems and the safest way to run a grill off a large
tank. This is similar to residential installations.

not seem to supply enough gas for my appliance." Unfortunately, many of the
preset low pressure regulators available in the marketplace use 1/4"ID hose and
some are attached to a propane regulator with a 1/4" NPT (normal pipe thread)
outlet on the propane regulator. There is a limit to the volume of gas that can
be delivered through this small ID hose at a fixed low propane pressure of 6
ounces . What can you do? Use a low pressure regulator with a 3/8"ID gas
outlet and a gas hose of 3/8"ID. The amount of propane that can be delivered to
the appliance is increased by a factor of 2.26 so the chances of starving your
appliance for propane are greatly diminished. GasHosesandRegulators.com sells
only 3/8" NPT outlet low pressure gas regulators and 3/8"ID low pressure hoses
for this very reason. Our grey hose carries UL , CSA, and American Gas
Association approvals and is designed to supply up to about 100,000 btu/hr of
propane gas."
