    Not to Sound Rude

    But isn't that what the installation manual is for?
    "The bitter taste of a poor installation remains much longer than the sweet taste of the lowest price."
  • yeah

    now that you mention it, i didnt a purchase boiler yet, so i dont have a manual. i was thinking about a WM ultra and i havent installed any yet. a friend told me that it requires primary secondary piping. i just like to have a good diagram to go by . something general. i do like your quote cris, im a big believer in that. if only the homeowers around the world would realize that!!

    Things you WON'T see in an I&O manual....

    Critical things if you want to avoid ANY potential issues in the future...

    It's not so much a case of "You got what you paid for", as it is a matter of "You DIDN'T get what you DIDN'T pay for, and you're NOT going to get what you thought you were in the way of comfort". Borrowed from Heatboy.

    Thanks Mark

    I see these errors in a lot of boilers I service by other companies. The manuals really should point out those critical pipe distances between tee's, 90's etc.

    another reason why

    we like hydraulic separators and low-loss headers.
