MASONRY FIREPLACE INSERT INSTALLATION, MODEL FPI 
The Fireplace insert model includes a surround faceplate and a pedestal. When installing this unit, 
ensure that the pedestal is removed from the inside of the hopper and installed on the bottom of the 
unit. (Surround assembly instructions are in this manual) 
CLEARANCES TO COMBUSTIBLES 
Side wall  8” (200 mm) from the body of the heater 
Facing on masonry fireplace  8” (200 mm) from the body of the heater 
Mantle  8” (200 mm) from the body of the heater 
FIREPLACE INSERT SIZE: 
Width 22”(550 mm) 
Height 22 3/4(570 mm)

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 ENVIROFIRE model 
FS and install as a hearth mounted unit.  Install a 3” (76 mm) flex pipe from the stove to the top of the chimney.
