All advantages of this up-to-date
Furnace duly considered, it is easily
worth the price of the boiler many
times over.

Better firing door facilities, strong
clean fires with maximum draught
and evaporation maintained with
very inferior fuels, low cost of
Furnace upkeep, saving of labour,
etc.

It has more practical common sense
points of merit than any other design
of Furnace in use.

Reject substitutes “just as good" with-
out a guarantee just as good in writing.
