VENTING FIREPLACE INSERTS:

The ENVIRO Sonnet may be installed and vented into any solid fuel fireplace that has been installed in accordance with the National, Provincial/State and local building codes and has been constructed of non-combustible materials. Before starting, refer to INITIAL INSTALLATION - PREPARING YOUR SONNET FOR

INSTALLATION and INITIAL INSTALLATION - CONVERTING A DIRECT VENT FIREPLACE TO A B-VENT FIREPLACE. Please

reference the information in Table 5 and Figures 39, 40, and 43.

An approved chimney liner and rain cap must be used. A throat connector or flashing must be installed to ensure a tight seal, top performance, safety and efficiency. Carefully follow the manufacturer’s instructions that accompany the chimney liner kit. Use listed B-Vent or Flexmaster double walled aluminum flex vent.

If necessary, remove the vent collar plate from the top of the insert and connect it securely to the liner with sheet metal screws and/or hose clamps. Check for any tears in the liner at this point. IMPORTANT: The screws that hold the vent collar plate in its approved position must be installed.

Provide for proper and adequate venting and air supply for this appliance in accordance with the tables in the current National Fuel Gas Code, Z223.1/NFPA 54 or the CSA B149.1.

NOTE: If the Sonnet unit is pulled out of its installation, and the vent air intake system is disconnected for any reason, ensure that the vent-air intake pipes are re-sealed with high-temperature sealant or silicone and reconnected with three
