    Did you search the internet ?  In 0.19 seconds I got 520,000 results  .just saying.  I do not know if they have an OG or not but you might find something.

    of course I tried searching, but the Google search didn't provide anything further (which leads me to believe I might have the wrong name here - might not exist at all). I've found plenty on Cleaver obviously, but nothing specific to an "OG" series. Thanks anyway!

    Cleaver Brooks

    I have been servicing CB's for 20+ years and still do several times a week.  The only model that had a G in it was the WGX series.  There was a series of custom industrial process watertubes built in the early 70's that may have had a G in the model number, but I am at a loss on the OG model number.

    Do you have a picture?

    The only thing that I can think of would be "oil or gas", possibly a duel fuel?

    OGEE is a designed wood shape. You can buy molding with that shape.

    Also, in Massachusetts (I don't know about other states). Cleaver- Brooks are large commercial boilers. Not found in 1200 Sq. Ft. Cape's and Ranch's. So as of some recent date, any commercial boiler running on Nat. Gas has to be able to switch to oil if it is too cold out and the gas companies are having issues with excessive demands that they can't meet. They have to be able to seamlessly drop off the gas grid and switch to oil during the emergency. Or so I was told. And why burner manufacturers like Power Flame have a GO-* model dual fuel burner.

    I've not had the experience of a Cleaver-Brooks application, but maybe the "Cleaver-Brooks GO" is their boiler with their designed combination gas/oil burner.

    Dual Fuel Model:

    You are very correct Ice.

    The smallest water CB is the Clearfire in 4 million Btu/hr.  They do have a version of the classic CB in steam that is supposedly available in as small as 15 boiler HP, but the smallest that I have ever seen is 80 boiler HP.  That would be 2 million Btu converted from boiler horsepower.

    CB's are most often seen in schools, hospitals, nursing homes, and universities.  They do have an industrial process line that we see in smaller manufacturing facilities.

    I service one that is bigger than a 1,200 sq ft Cape.  It is making steam for a medical equipment manufacturing facility.

    I was just looking though the CB Internal Tech secure website.  There is an OSSG model.  It is 227 Tons of steam per hour.  that is 500,000 lbs per hour.  That is A LOT of steam.  It is an industrial application boiler.  Heavy Oil Sands specific.

     "" Heavy Oil Sands specific. ""

    They gonna run a spur from the Keystone Pipeline and drop off loads of that Canadian tar sand crude while it is on the way to a refinery? To be refined into product to be shipped overseas and sold on the open market? (shipped back to the USA to be sold to the highest bidder on the Spot Market.
