CONNECTION TO A MASONRY CHIMNEY THROUGH A COMBUSTIBLE WALL
The heater may be connected to a masonry chimney, which conforms to the installation code requirements. Various
methods of connection are shown in these installation codes. Check with your local regulatory authority as to which
methods they will accept. Care must be taken when the chimney connector passes through a combustible wall to
ensure that there is sufficient clearance from the chimney connector to the combustible wall material.

1. There is a connector that extends from the heater to the flue liner of the fireplace.
2. The cross-sectional area of the flue is no more than three times the cross-sectional area of the flue collar of the
room heater.
3. There is a non-combustible seal below the point of entry of the connector.
4. The installation conforms to the requirements of your local codes (NFPA211 - USA), (B365 – Canada) Check with
