Chimney Vent
Failure to provide correct chimney venting can lead to increased
carbon monoxide production and increased emissions of combustion
gases into the building, which may cause death or serious injury.
Do not connect this heating appliance to a
chimney flue serving any other heating
device.
Step 1: Make sure an approved lined masonry
or listed chimney is installed for the A-MAIZE-
ING HEAT
®
furnace. All chimneys and
connections made to the chimney must comply
with NFPA Standard 211 and all applicable
building codes. Consult a qualified furnace
installer and/or local building inspector to make
sure the chimney and connections comply.
Refer to “Venting” on page 6 and “Venting
Information” on page 34 for additional
information.
Step 2: Make sure the furnace and storage bin
are correctly placed. Refer to “Furnace
Clearances and Accessibility” on page 5 for
proper clearance dimensions.
Step 3: Connect furnace to chimney with 6"
metal flue pipe using sheet metal screws to
secure (refer to “Venting” on page 6).
Barometric Draft Control
Install the baromatric draft control according to
the directions beginning on page 36. It will be
adjusted (refer to “Draft Adjustment” on
page 15) after the installation of the furnace is
complete and a fire has been built
Draft Guage
The draft guage is installed to monitor the
chimney draft measured in inches of water
column. The A-MAIZE-ING HEAT
®
furnace
requires 0.04 to 0.06 water column inches of
draft.
Install the draft guage as follows:
NOTE: There are parts in the kit that will not be
used in this installation.
Step 1: Remove gauge and installation
accessories from box.
Step 2: Select an installation location close to
the flue pipe where the gauge can remain
level.
Step 3: Hold gauge in position and install one
1-3/4" screw through top hole (1); do not fully
tighten.
Step 4: Level unit with bubble level (2) located in
face of unit and install a second 1-3/4" screw
through bottom hole (3); do not fully tighten.
Step 5: Check level of unit and tighten screws.
Step 6: Drill a 1/4" hole into the flue connection
pipe at a location between the furnace flue
connection and the barometic draft control.
