DRAFT
Draft is created by the heated air rising in the chimney system. This draft will pull fresh combustion air
into the firebox. Recommended draft is .05 in. w.c at high fire. Too little draft results in a sluggish fire
and smoking when the furnace door is opened. Too much draft (over 0.06 in. w.c.) makes it unsafe to
operate the furnace. Use a barometric control if necessary to avoid excessive draft.
DO NOT OPERATE THE APEX WITH A DRAFT OF OVER .06 INCHES WATER COLUMN. HIGHER
DRAFT LEVELS MAY CAUSE THE FIRE TO BURN OUT OF CONTROL AND CREATE A FIRE
HAZARD.
VENTING SYSTEMS
The venting system consists of a flue pipe and a chimney. These get extremely hot during use.
Temperatures inside the chimney may exceed 2000 degrees in the event of a creosote fire. To protect
against the possibility of a house fire, the flue pipe and chimney must be properly installed and
maintained. A listed thimble must be used when a connection is made through a combustible wall to a
chimney. A chimney support package must be used when a connection is made through the ceiling to
a listed prefabricated chimney. These accessories are absolutely necessary to provide safe
clearances to combustible wall and ceiling material.
This furnace may be connected to a lined masonry chimney or a listed factory built chimney suitable
for use with solid fuels and conforming to, ULC629 in Canada or UL-103HT in the USA. Do not
connect it to a chimney serving another appliance. To do so will affect the safe operation of both
appliances, and will void the furnace warranty.
You must comply with the local authority having
jurisdiction and/or in Canada, CSA installation standard B365-M87.
The flue pipe must be 7” diameter, 24/26 MSG Back/Blue steel. Do not use aluminum or galvanized
steel. They cannot properly withstand the extreme temperatures of a wood fire. The flue pipe between
the furnace and the chimney should be as short and direct as possible. Blaze King recommends the
use of double wall pipe and two 45° elbows instead of a single 90° elbow. A minimum 36” rise is
recommended prior to any elbows being used.
The flue pipe must be attached to either an approved masonry chimney or one of the listed factory
built chimneys suitable for use with solid wood fuel. All joints must be tight and fastened with sheet
metal screws.
WARNING: The flue pipe is to be used only within the room, between the furnace and ceiling/
wall. Never use a flue pipe to pass through a combustible ceiling or wall. Always maintain the
minimum clearances to combustibles as required by the applicable building codes.

DIGITAL MONITOR
Mount the digital monitor on either the left or right side
of the cabinet and connect thermocouple wire to the
monitor. This monitor shows the temperature of the
catalyst. Press the red button and the temperature will
be displayed for 30 minutes. When temperature is
below 500 F, “COOL” will be displayed.
