CAUTIONS
1. All installations must comply with local building safety codes.
2. Installation shall be by a licensed, qualified installer experienced in heating equipment installations.
3. THE WOOD SECTION MUST BE VENTED INTO A CHIMNEY APPROVED FOR SOLID FUEL USE
IN GOOD CONDITION. MOST GAS FURNACES ARE VENTED INTO "B" VENTS, THIS IS UNAC-
CEPTABLE FOR SOLID FUEL APPLIANCES. THE APEX CBT MUST NOT BE VENTED INTO ANY
TYPE OF CHIMNEY THAT ALSO SERVES ANOTHER APPLIANCE.
4. DO NOT CONNECT THE DUCT WORK SO REVERSE OR PARALLEL FLOW IS POSSIBLE.
5. DO NOT RELOCATE ANY OF THE CONTROLS ON THE ORIGINAL OR ALTERNATE FURNACE.
6. Ensure that all existing or alternate furnace systems are in good operating condition before installing
the add-on. Always maintain required clearances from the existing or alternate furnace.
7. The warm air supply duct system need to be constructed of metal in accordance with NFPA 90B,2-1.1
8. The plenums installed to the furnaces need to be constructed of metal in accordance with NFPA 90B,2-

Blaze King supports the WETT ( Wood Energy Technology Transfer Inc, Canada) & NFI
(National Fireplace Institute, USA). These organizations provide training and certification
for personnel involved in installation and maintenance of wood heating systems.
If the furnace sits on a combustible floor, a non-combustible shield must be used underneath the
furnace and extending 18 in. out from the charging end and 8 in. on either side of the fuel-loading
door. A non-combustible shield is also required underneath the chimney connector and extending
at least 2 in. on either side of the chimney connector. (minimum size floor protector= 65” x 31.5”)
This floor protection is required to prevent sparks from falling onto the combustible floor. See CSA
B365-M87). It is not required to be a heat protective covering.
This furnace must be installed in compliance with all local codes and regulations.
