E. Draft Test Procedure
Because of the dangers associated with coal gases
and the potential for carbon monoxide release, It is
important to balance the airow into the stove with the
draft in the ue. The combustion blower has a restrictor
plate attached to it, which must be adjusted upon
completion of the installation. The barometric damper,
if installed, must also be set to prevent over-drafting in
the appliance. Follow these steps to ensure safe and
efcient operation of your Super Magnum coal stoker
stove.
You will need to start a re in the appliance to
establish a draft in the chimney ue. Refer back to
these instructions after reading the entire manual.
• Drill a hole into the ue connector pipe, for the
purpose of attaching a draft meter. This hole should
be between the barometric damper and the stove's
ue collar, and in an inconspicuous location, as it
will be closed off after the test with a bolt.
• Attach the draft meter to the hole in the connector.
A great chimney will have draft without a re or heat
source. Set the barometric damper to maintain -.06
to -.08 (inches of water column).
• Remove the draft meter from the connector pipe
and seal the hole by threading in a screw or
bolt. You may also want to apply a small dab of
high-temperature silicone to the threads prior to
installing.
• Next, remove the set-screw plug bolt from the front
of the Super Magnum body. This plug is located in
the center, just below the top load door. Attach the
draft meter hose to the stove.
• Turn the feed adjuster knob to "Test". This will
run the combustion blower at its highest possible
voltage or speed.
• Close the restrictor over the opening to the
combustion blower until the draft reading in the
rebox ts the -.03 to -.04 range. This will ensure
that the combustion blower will never push more air
into the rebox than the draft in the ue is capable
of removing.
• Disconnect the draft meter from the stove and re-
install the set screw plug bolt.
