Installation Guide

PG 5
Cold Climates: In cold climates, chimneys mounted on an outside wall should be
enclosed in a chase. Exterior chases reduce condensation and creosote formation, and
enhance draft. Include an access door by the Tee Cap for chimney cleaning (refer to
Fig 21, page 16).
STOVE RECOMMENDATIONS
Follow the stove manufacturer’s instructions. The requirements stated below pertain to
all stoves or other appliances installed with Model AF-HST systems.
Choice: Choose an appliance that is listed by a recognized testing laboratory, is
appropriate for your needs, and is not larger than required.
Installation: Once the chimney system is in place, install the stove pipe to connect the
appliance to the chimney as described in the appliance manufacturer’s instructions. Be
sure to maintain all required clearances.
Flues: Connect only one solid fuel appliance per chimney.
Operation: Follow the appliance manufacturer’s instructions for maximum efficiency
and safety. Over firing can damage the appliance, stovepipe and chimney.
Fuels: Do not burn driftwood, plastic, or chemically treated wood such as railroad ties.
They are corrosive to your appliance, stovepipe and chimney. Follow the appliance
manufacturer’s instructions and safety manual in regards to fuels. Not all appliances
are equipped to burn coal. Coal with a low sulfur content will reduce the possibility of
corrosion.
Mobile Homes: Please read the appliance manufacturer’s instructions and safety
manual carefully. Not all appliances are listed for use in mobile homes.
