 Propane Question...Sendiment Trap really needed?

I just bought a propane heater.....it says that a sendiment trap needs to be installed between the
heater and the tank.....is this really needed, if I run it off a 20 lb BBQ tank?
How do the BBQ grills run without them?

Also got a propane generater.....will it need one too?

Thanks,

Dunno about the generator since I believe they use liquid fuel.
But the heater should have a sediment trap because the jet can
get clogged by particles of rust or dirt. You can get by without
one, but for an installed unit it isn't difficult to plumb and may save
headache in the future, so why not?

The biggest concern would be if you had the line run down to a below ground level, and then straight into the appliance. In this case, the sediment would fall down the line and be pushed into the jet by the gas.

Of lesser concern is gas pulling sediment uphill and then into the appliance.

What you do is of course up to you.

I believe that it's more of a condensate trap. the most problem you might encounter is an air blip or moisture droplet
that would make your gen set cough or your pilot on your heater go out.

Only really large motors on generators use liquid propane as fuel. Normal size and smaller ones use propane vapor.

Often confusion is a result of referring to propane as LP or liquid propane. It actually is liquid in the tank, but most often the boiled off vapor is what is used to run appliances like generators and BBQ's, etc.

The short answer is yes, if you have the appliance hard-piped in place. Crud does get in there somehow, and it can clog the orifice and stop you cold.

Portable applianes would be difficult to install a trap in place. It's still a good idea.

If you use the cheap rubber hose on buddy heaters to hook up a 20lb tank you will usually find after a season of regular use that the pilot light is clogged up and needs cleaning. I bought one of the $10 or so screw in filters and ran 3 or 4 20lb tanks through my little buddy heater so far this winter and have had no problems.

There is a more expensive extension hose that will not leach oil out and you can skip the filter with these. Never seen one in person but it would be my recomendation.

You can clean the buddy heaters out, I have a big one torn apart and have been slow to finish cleaning the lines out and put it back together.

But I plan to just use the filters from now on since all I use right now are buddy heaters as far as portable propane stuff is concerned.

As far as a normal outdoor propane grill goes, part of what you might get into is different orifice size and what not. I also need to replace my burner finally but I have cleaned it once before when I first got it.

This has happened at least twice with my unvented gas logs in my home. The pilot light won't stay lit is the usual sign. I have dismantle the logs setup (no gbiggie) then take apart the orifice and blow it out. The orifice is a really small hole and it's easy for it to get plugged up.

Cabela's sells a filter for Mr. Buddy Heater applications as seen here: Cabela's Mr. Buddy filter
