KEYSTOKER Forced Warm Air Heating Units
can give you automatic heating
at the lowest possible cost. You can definitely benefit by the
use of anthracite coal and at the same time eliminate the time and work
demanded by hand-feeding. A large silent air circulating blower
will assure complete circulation of warm, filter-cleaned air throughout
every room in the house.
The KEYSTOKER Warm Air Furnace is built
to deliver maximum heat at the
lowest initial investment and lowest operational cost. The
down-draft heat exchanger increases heating surface, permitting direct
circulation of every thermal unit of heat into the warm air leader
pipes for rapid distribution. The heating surface is properly
proportioned to the grate area, resulting in appropriate balance and
greater heat delivery per pound of fuel burned. Fibre Glass
air filters can be easily cleaned or replaced at a low cost.
The Keystoker blower has been
expertly
engineered and designed to give
many trouble-free years of silent operation. An optional
stainless steel hot water coil is available. Includes a sealed pit ash
removal, assuring clean, dust-free operation.
