Orifice Size/Altitude Adjustment

For altitudes above 2,000 feet (In Canada 4,500 FT/1370 

M),the orifice should be de-rated by 4% for every 1,000 feet 

to maintain the proper ratio of gas to air. Improper orifice 

sizing may result in damage and unsafe conditions. Chang-

ing the orifice should only be done by a qualified service 

technician. Contact your Lennox Hearth Products dealer for 

proper orifice sizes.

Fireplace Requirements

These heaters are designed to be installed into an existing 

masonry fireplace (built to UBC 37 or ULC S628 standards) 

or factory built solid fuel, wood burning fireplace (listed to 

UL 127 or ULC S610) only. All exhaust gases must be vented 

outside the structure.  Combustion air is drawn from outside 

the structure. When installing in a factory built fireplace, the 

fireplace grate must be removed and the damper must be 

removed or secured open.

WARNING

THIS FIREPLACE HAS BEEN ALTERED TO 

ACCOMMODATE A FIREPLACE INSERT AND 

SHOULD BE INSPECTED BY A QUALIFIED 

PERSON PRIOR TO RE-USE AS A 

CONVENTIONAL FIREPLACE.

If  the  factory-built  fireplace  has  no  gas  access  hole(s) 

provided, an access hole of 1-1/2 inches (38 mm) or less 

may be drilled through the lower sides or bottom of the 

firebox in a proper workmanship like manner. This access 

hole must be plugged with a non-combustible insulation 

after the gas supply line has been installed.  The installer 

must mechanically attach the marking supplied with the gas 

fireplace insert to the inside of the firebox of the fireplace 

into which the gas fireplace insert is installed.

IMPORTANT: When installing these appliances into a fac-

tory built fireplace or heat-form, the air flow within and 

around the fireplace shall not be altered by the installation 

of the insert (i.e. DO NOT BLOCK louvers or cooling air 

inlet or outlet ports, circulating air chambers in a steel 

fireplace liner or metal heat circulator).
