IMPORTANT: For information on connecting
the A-MAIZE-ING HEAT
®
boiler for a particular
application, contact and use the services of a
certified boiler installer.
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
®
boiler. All chimneys and
connections made to the chimney must comply
with NFPA Standard 211 and all applicable
building codes. Consult a qualified boiler
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 29 for additional
information.
Step 2: Make sure the boiler and storage bin
are correctly placed. Refer to “Boiler
Clearances and Accessibility” on page 5 for
proper clearance dimensions.
Step 3: Connect boiler 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 31. It will be
adjusted (refer to “Draft Adjustment” on
page 14) after the installation of the boiler 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
®
boiler
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.
