PICTURE FRAME FRONT
The front and back of the furnace is
built of 10 gauge steel and painted
with high temperature black paint. The
22 gauge painted side panels are de-
signed to slide onto the flanged steel
for easy installation.
LARGE LOADING FIRE DOOR
WITH POSITIVE DOOR LOCK
This 13” x 13” opening allows for easy
loading and larger diameter split logs.
The positive door lock ensures that
smoke and heat will not escape from
the furnace.
The round cast iron disc allows sec-
ondary air over the flame. It helps burn
smoke and unburned gases that leave
the flame, thereby increasing efficien-
cy.
FORCED DRAFT COMBUSTION
BLOWER
This furnace operates on a forced draft
principle. When the thermostat is call-
ing for heat, the Draft Blower will turn
on to get the fire burning. Draft blower
disc must be open.
HONEYWELL TRANSFORMER /
RELAY
These Honeywell Transformers are the
industry standard and made for heating
systems. This 24V control circuit step-
down transformer is designed to power
any 24V control system, including ther-
mostats and relays.
EASY ACCESS ASH PAN
Designed to allow for easy removal of
ashes. Pulls out of furnace, equipped
with additional cross bar handle for
easy ash disposal.
HIGH TEMPERATURE FIREBRICK
1-1/4 thick Hi-Temperature firebrick
surrounds the wood/coal fire. The
Big Jack features 90 pounds of fire-
brick. This firebrick not only protects
the steel from the extreme combustion
temperature in the firebox, but it also
retains a substantial amount of heat
after the wood/coal fire burns down.
HEAVY CAST IRON GRATE
It is imperative that 80 percent of the
air for combustion enter the firebox
from below a wood/coal grate to in-
sure an efficient and clean burning fire.
This grate is made of heavy cast iron
that can endure the temperatures of
wood and coal fires.
