Installation
15
Have your system cleaned by a certied
chimney sweep if you have doubts about
your ability to clean it. Use a plastic or exible
steel brush. Do not use a stiff brush
that will scratch the stainless steel liner of your
system.
PelletVent systems must be installed so that
access is provided for inspection and cleaning.
The pellet vent should be inspected at least
once every month during the heating season.
Do not use chemical cleaners. They can
damage the vent pipe.
To increase pellet vent life, coat all exterior
metal parts with high temperature, rustproof
paint. This is highly recommended, particularly
in areas near the ocean.
In case of a chimney re, close all appliance
draft openings, shut off pellet appliance and
call your Fire Department. Do not use the
appliance or vent until it has been inspected
for possible damage.
DuraVent is not responsible for ue by-
products that might discolor
roofs or walls.
A major reason for accelerated vent corrosion
from burning corn is due to acidic condensate
forming in the system. When operating your
corn-burning appliance, always follow the
appliance manufacturer’s installation and
operating instructions. In addition, DuraVent
offers these recommendations to help
minimize condensate formation in the vent:
Be sure to follow the recommendations
of the appliance manufacturer for the type
of corn fuel to use. However, the moisture
content of corn contributes signicantly to
condensate in the vent. The lower the moisture
content of the corn, the less condensate you
are likely to have in the vent. While corn with
a moisture content of 15% may be allowed
in the appliance, using a fuel with lower
moisture content will help reduce condensate
formation. Condensate is more
likely to form in longer vents because the
exhaust temperature cools further away from
the appliance. If the exhaust cools to a certain
point, moisture in the exhaust condenses in
the vent, which can lead to accelerated vent
corrosion. Keep the vent for corn-burning
appliances short wherever possible to
maintain hot ue gas temperatures and keep
moisture suspended in the exhaust. If a longer
horizontal vent or taller vertical vent is needed,
it is recommended that the vent run inside the
building envelope or inside a chase enclosure
to minimize the vent’s exposure to cold
temperatures. Be sure to follow all-applicable
building codes and the requirements of the
vent and appliance manufacturers.
Always operate your appliance in
accordance with the appliance manufacturer’s
recommendations. However, operating the
appliance at its lowest setting has a greater
chance for condensate to form in the vent due
to the low exhaust temperature. In order to
help reduce condensate from forming inside
the vent system, operate the appliance at
higher temperatures when colder weather is
encountered. Higher operation settings provide
for warmer ue temperatures, which help to
keep moisture suspended in the ue gases.
When burning
corn, be sure to inspect the appliance and
vent often to determine if there has been any
corrosion or damage to the system. Be sure
to keep the venting system clean, including
the tee cap (if applicable). The ash that results
from burning corn can trap condensate in
the tee cap and inside the vent, hastening
corrosion to the system if left unchecked.
