Cleaning a Prestige

[Deleted User]

that I see "Cleaning a Prestige" to answer my question about the Prestige's heat exchanger being self-cleaning. He also thought this should be a new thread, so here it is.

The Prestige manual requres that, as part of annual maintenance, the boiler be placed on high fire, then flue temperature is compared with supply water temperature. If the flue is more than 54 degrees F higher than the water, exchanger cleaning is mandated; the manual provides a complete cleaning procedure.

I'm curious how often those who have performed these annual checks find the temperature difference great enough to require cleaning. Or has the "self-cleaning" design kept you from ever needing to?

I can't find any document called "Cleaning a Prestige" here, on triangletube.com or via a general Internet search.

Thanks in advance.
