Hello all,

I own a ten-year old gas grill. I had the propane cylinder refueled and
when I returned home and connected it to the regulator, all sorts of
problems began: gas leakage at the cylinder head and regulator freeze-up.

I returned the cylinder to the fill station believing that it had perhaps
been overfilled. The attendant noted that the cylinder was ten years old
and suggested I buy a new one, which I did.

I went back to the same fill station with the new empty cylinder, had it
filled but the regulator freeze-up problem reoccurred albeit not as much.
No gas leakage but frost formation on the regulator and hose.

I replaced the regulator with a new one... same problem. I then concluded
that the problem must be with the burners themselves which I also
replaced. The problem persists with a bit of burner flutter.

I live in Montreal and hot weather is not the issue. The temperature
yesterday was ± 70 F (20 C).

So, new parts a gas cylinder (not equipped with the overfill
protection device), regulator assembly with single hose, and the burner
assembly including two venturis.

Conclusion: is the culprit the propane gas itself? Is it possible that
the fill station's propane gas is causing a problem or am I overlooking
something?

Having owned two diesel powered automobiles, I was often warned to
purchase fuel only from a busy station because there exists the risk of
water build-up in old diesel fuel. Is this an issue with propane?

Many thanks for your help!

whats the humidity at your location yesterday?

gas expands and cools lines when it goes thru regulators. this is
normal. on a high humidity day it will be noted as frost.

did you use the grill? it probably worked fine?

i doubt anything in the gas could cause outside frost beyond what
normall occurs.

Thanks for the info to everyone!

The only parts I hadn't messed with were the control valves. I read that
spiders, etc... could clog these.

I took them apart and cleaned them as best I could. This seems to have
solved the problem.

I think the humidity dropped so you dont see the frost.

A bug or clog will obstruct the flow, no or little heat, lower flow
less chance or frost on lines

on a brite note you have now serviced the entire grill, thats always a
good idea
