A noncombustible hearth pad
must cover combustible flooring
underneath, as well as 6” (150 mm)
in front of the heater and 6” (150
mm) to the side of the heater
1. Install the hearth pad.
2. Lock the fireplace damper in the
open position.
3. Install a positive flue connector at
the fireplace damper.
4. Connect a tee or 90° degree elbow
to the exhaust pipe.
5. This fireplace insert must be
installed with a continuous
chimney liner of 3 or 4” diameter
extending from the fireplace insert
to the top of the chimney. The
liner must conform to type 3
requirements of CAN/ULC S635.
6. (Recommended) Install fresh air
intake either through the back
of the fireplace or through the
positive flue connector.
When installing the insert into a masonry fireplace DO NOT remove any bricks or masonry, with the
following exception; masonry or steel, including the damper plate, may be removed from the smoke shelf
and adjacent damper frame if necessary to accommodate a chimney liner. Provided that their removal
will not weaken the structure of the fireplace and chimney, and will not reduce protection for combustible
materials to less than that required by the national building code.
When installing the fireplace insert into a zero clearance fireplace, DO NOT cut or modify any factory
firebox parts. If the fireplace insert does not fit into a zero clearance fireplace we recommend you use
an ENVIRO freestanding model and install as a hearth mounted unit. Install a 3” (76 mm) flex pipe from
the stove to the top of the chimney (see “INSTALLATION - HEARTH MOUNT INSTALLATION - FREESTANDING”).
