In addition to the previously detailed installation requirements, mobile home installations must meet the following requirements: •...
  • Page 6 CHIMNEY CONNECTOR (STOVE PIPE) Your chimney connector and chimney must have the same diameter as the stove outlet (6”). If this is not the case, we recommend you contact your dealer in order to insure there will be no problem with the draft. The stove pipe must be made of aluminized or cold roll steel with a minimum thickness of 0.021”...
  • Page 7 CHIMNEY Your wood stove may be hooked up with a 6” factory built or masonry chimney. If you are using a factory built chimney, it must comply with UL 103 or CSA-B365 standard; therefore it must be a Type HT (2100°F). It is extremely important that it be installed according to the manufacturer’s specifications.
  • Page 8 MASONRY CHIMNEY Ensure that a masonry chimney meets the minimum standards of the National Fire Protection Association (NFPA) by having it inspected by a professional. Make sure there are no cracks, loose mortar or other signs of deterioration and blockage. Have the chimney cleaned before the stove is installed and operated. When connecting the stove through a combustible wall to a masonry chimney, special methods are needed.
  • Page 9 FACTORY BUILT CHIMNEY When a metal prefabricated chimney is used, the manufacturer’s installation instructions must be followed. You must also purchase (from the same manufacturer) and install the ceiling support package or wall pass-through and “T” section package, firestops (where needed), insulation shield, roof flashing, chimney cap, etc. Maintain proper clearance to the structure as recommended by the manufacturer.
  • Page 10 COMBUSTIBLE WALL CHIMNEY CONNECTOR PASS-THROUGHS Method A. 12” (304.8 mm) Clearance to Combustible Wall Member: Using a minimum thickness 3.5” (89 mm) brick and a 5/8” (15.9 mm) minimum wall thickness clay liner, construct a wall pass-through. The clay liner must conform to ASTM C315 (Standard Specification for Clay Fire Linings) or its equivalent.
  • Page 11 Wood Operating Instructions WOOD UTILIZATION Your heating unit was designed to burn wood only, no other materials should be burned. Waste and other flammable materials should not be burned in your stove. Any type of wood may be used in your stove, but specific varieties have better energy yields than others.
  • Page 12 It is EXTREMELY IMPORTANT that you use DRY WOOD only in your wood stove. The wood should have dried for 9 to 15 months, such that the humidity content (in weight) is reduced below 20% of the weight of the log. It is very important to keep in mind that even if the wood has been cut for one, two or even more years, it is not necessarily dry, if it has been stored in poor conditions.
  • Page 13 CAUTION: Never alter the damper slide or the adjustment range to increase firing for any reason. Doing so could result in heater damage and will void your warranty. HEATING Controlled combustion is the most efficient technique for wood heating because it enables you to select the type of combustion you want for each given situation.
  • Page 14 We strongly recommend that you install a magnetic thermometer on your smoke exhaust pipe, approximately 18” above the stove. This thermometer will indicate the temperature of your gas exhaust fumes within the smoke exhaust system. The ideal temperature for these gases is somewhere between 275°F and 500°F. Below these temperatures, the build-up of creosote is promoted.
  • Page 15 GLASS • Inspect and clean the glass regularly in order to detect any cracks. If you spot one, turn the stove off immediately. Do not abuse the glass door by striking or slamming shut. Do not use the stove if the glass is broken.
