prEcautIons

Note: These fireplace systems are not difficult

to install. However, in the interest of safety, it

is recommended that the installer be a qualified

or certified “tradesman” familiar with com-

monly accepted fireplace installation and safety

techniques as well as prevailing local codes.

The most important areas of concern dealing

with the installation of factory-built fireplaces

are clearances to combustible materials, proper

assembly of component parts, height of the

chimney system, the proper use of accessories

supplied by the manufacturer and the techniques

employed in using finishing materials applied

to the wall surrounding the fireplace, hearth

extensions and wall shields. Each of these topics

will be covered in thorough detail throughout

this manual. Please give each your special at-

tention as you progress with your installation.

tive glass doors.
Note: Illustrations reflect “typical” installations

with nominal dimensions and are for design

and framing reference only. Actual installations

may vary due to individual design preferences.

However, always maintain minimum clearances

to combustible materials and do not violate any

specific installation requirements.
models Est-36 and Est-42 have been tested

and listed to U.L. 127 standard for U.S. instal-

lations and U.L.C. S610 standard for Canadian

residential homes and buildings of conventional

construction, not in mobile homes.
These fireplace systems are designed for in-

stallation in accordance with the National Fire

Protection Standard for chimneys, fireplaces

and solid fuel burning appliances; NFPA 211

and in accordance with codes such as the BOCA

Basic/National Codes, the Standard Mechani-

clEarancEs and hEIght

rEquIrEmEnts

The fireplace may be placed on or near normal

construction materials.* The combustion air kit,

firestop spacer and roof flashings (not chase

flashings) may be placed directly on or against

normal construction materials.* The chimney

requires a minimum 2" (51 mm) air space to

combustibles. A combustible mantel may be

installed a minimum of 12" (305 mm) above

the opening of the fireplace as per NFPA 211,

“Mantel/Trim Clearances” Section. In Canada the

minimum is 24" (610 mm) above the opening.

The fireplace and chimney system must be

enclosed when installed in or passing through

a living area where combustibles or people may

come in contact with it. This is important to

prevent possible personal injury or fire hazard.

For questions, please call your distributor or

the manufacturer. Special restrictions apply to

the front and facing of the fireplace and nearby

walls (see pages 20 and 21).
