EFM 520 regular maintenance

Hi, what kind of maintenance is needed or suggested to get the longest life and maximum efficiency out of my boiler? Is there anything that should be done weekly, monthly, yearly? Also; where can I get a shear pin for the auger? I used a cotter pin that fit in the hole, is that acceptable?

A cotter pin is too strong, the idea is that it breaks instead of the auger. Suggest you go to a welding store and pick up a brass brazing rod. Those fit our Van Wert perfectly.

The hardware store should have an assortment of shear pins made of aluminum, most likely in the fastener area.

Shear pins are available here or at your local dealer. They only cost pennies and are designed to break instead of your expensive worms. Call efm at 610 965 9041 and ask for some pins.

I will write a separate response to the pin shearing problem so all can read it.

Good deal, Rich is sending me some. +1 for EFM customer service.

Thanks, we go the extra mile to keep people happy.

The best thing that you can do for your stoker is to fill it once and never add water again. In the real world, that means fix any tiny leak immediately. Check especially around the coil gasket. You can develop a leak there and never even know, as the water will evaporate quickly. Coil patch plates are available for stokers which have had leaks and won't seal anymore.

Introducing fresh water into a boiler because of a leak is a quick way to rust it out.
