One for the (really) Old Timers!

Visiting relatives near Toronto, I find they have an incredibly old warm-air furnace in their recently-purchased house.  It has obviously had additions over the years (a humidifier and an A/C coil in the Return air duct, at least, plus possibly a non-standard gas valve).



However, it seems to still be working - maybe as well as it ever did!  All it definitely needed was a new fan drive belt.  In general, it looks fine.  The Home Inspector reported it as 'about 25 years old' but OK.



Furnace is a Roberts Gordon GL100-A.  Gas valve is White Rogers 36C03.  As far as I can discover, Roberts Gordon stopped making this model in 1969!



Anyone remember anything about this furnace? 



I'm thinking maybe at least a smoke test of the heat-exchanger would be good idea.  But of course I'm from UK and like a fish out of water in Canada.  Where would I get a smoke cartridge in Hamilton, Ontario!!??

    Old

    From my memory Roberts Gordon made conversion burners not furnaces. The White Rogers valve is probably not original to that burner.

    I used to know the answer

    To that, but now, I'm such an old timer I can't remember;)

    REAL Roberts Gordon thru & thru

    The data plate is mounted on the casing of the furnace (inside) and is definitely showing the company name, the type (as above) and a serial number (starting 65, which might be a bit of a clue!).



    The burner system is an unusual design, consisting of an injector, a horizontal mixing tube / venturi, a right-angle bend upwards and a round burner, with the pilot assembly beside it.  Definitely could not be separated from the rest of the machine.
  • Too old?

    Luckily not too old to have a sense of humor!--nbc

    What you have is a

    Roberts Gordon up-shot atmospheric conversion burner. Many of these were powerpile self generating systems so if you had a power failure you could operate on gravity. I will have to look up that White Rodgers gas valve to see if it is a powerpile valve?

    If that valve is a

    36C03U-333 or -433 it is a powerpile gas valve.

    Re: Roberts Gordon

    Most of those were powerpipe 750 MV but there were some 24 volt units. We had the last of the old ceramic pie plate difusers for those burners up to about 5 yrs ago and finally used the last one. No longer to be had. When the crack and break apart the burner is done. They were pretty reliable albeit not too effiicient.
