before starting installation.

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 “
