WM GV6 - rusty burner cone

Max_4

Hi, we have a Weil-Mclain GV6 that has been acting funny, so I thought I'd give it a good cleaning.



The burner cone looks very rusty. Can I clean it or should I replace it?



Hopefully there's a photo attached of it -- the bottom half looks darker because it's damp.



Thanks!

Yes it can be cleaned

using a soft bristle brush will do fine.

only issue I have had with GV

boilers has been poor installations.

GV's:

I consider them almost bomb proof.

Like the Everready Bunny, it takes a lickin' and just keeps tickin'.

Where I work, there are hundreds of them installed. The same as Charlie, bad installs mean bad outcomes.

Really

Condensing CAST IRON boiler. Thats and oxymoron if there ever was. What are they on the third or forth revision of that clunker.

Charlie from wmass

If it is condensing in the boiler

it is installed wrong. The condensing should occur in the exhaust pipe. Thats why the tee is there to stop it from flowing back into the boiler. KN and Ray are condensing cast iron boilers.

Condensing GV's:

Especially the new GV 90+ with the stainless steel heat exchanger that the return water goes through.

All boilers suffer from bad installs. I once saw a GV in the back of a truck that someone stopped to show me and wondered why it had failed. (not installed by the person in the truck) It was direct connected to a pool heat exchanger and never saw any return water higher than 80 degrees and the outlet at less than 100 degrees. It looked like it had just pulled out of the harbor after doing time as a boat mooring.

As far as "revisions" were concerned, so many of them were installed without reading the install manuals that W/M had to Primary Secondary them inside to save them. Poor or incorrect installs don't make a bad boiler, it's the install.

So every time

Your gv fires up the return is above 135*f.
