PLANNING YOUR INSTALLATION

COMBUSTIBLE WALL CLEARANCE

WARNING: IT IS VERY IMPORTANT THAT YOU OBSERVE THE MINIMUM CLEARANCES.

There are listed clearances for your stove which were determined in a Laboratory test using various "classes" of stove pipe or chimney. Minimums are first established for the stove itself and increased based on how much heat is transferred by each class of pipe.

Do not install the T300HT in an alcove or a confined space, which would be a room or space with under a 7' (foot) ceiling, and less than 77" (inches) wide.

PROTECTED WALL CLEARANCE

Some local codes will allow reduced clearances when the stove is installed adjacent to a protected wall system. The variance must be approved by your local building official. Normally, the protected wall system is defined as a non- combustible material with a minimum of 1" air space behind. Check your local building codes or with a qualified installer (Ref. NFPA 211).

VENTILATION REQUIREMENTS

THE FRESH AIR REQUIREMENTS OF THIS APPLI- ANCE MUST BE MET WITHIN THE SPACE WHERE IT WILL BE INSTALLED.

Ventilation is essential when using a solid fuel burning heater. The combustion process of this heater uses oxygen from inside the dwelling and it may be neces- sary to open a window or install a vent to provide make- up air into a dwelling that is well insulated (modern con- struction standards have resulted in homes that are highly energy-efficient and that allow little heat loss and air transfer). Other appliances in the dwelling also con- tribute to removing air from the dwelling (i.e. clothes dryers, exhaust fans, fireplaces, and other fuel burning appliances). If the available fresh air delivery in the dwelling is insufficient to support the demands of these appliances, problems can result (i.e. excessive negative pressure can develop in the dwelling which will affect the rate at which this appliance can draft [See Draft Re- quirements, page 8], and icing can develop in some en- vironments).
