Introduction
Kratki.pl Marek Bal is a well-known manufacturer of heating equipment in both Poland and Europe.
Our products are based on strict standards. Each insert manufactured by the factory is subjected to
quality control during which it undergoes rigorous safety tests. The use of the highest quality materials
in the manufacture ensures smooth and reliable operation of the device by end users. This manual
contains all of the information necessary for proper installations, operation and maintenance of the
LEO 100 gas inserts.
NOTE!!!
Installation, inspection and maintenance of the tightness of the device can be carried out only by

INTRODUCTION
The LEO 100 gas inserts are closed heating equipment powered with flammable gas. This device is ETL
marked and uses high-end automation to control gas. The inserts meet the stringent North American
directives with regard to safety, the environment and energy consumption. The air supplied to the
combustion chamber is drawn from outside of the housing via a coaxial chimney system. This solution
provides the user with security because it prevents passage of exhaust gases directly into the room
where the fireplace operates. Before fitting the appliance, please read these instructions. The
information contained herein will allow you to obtain trouble-free operation of the device. This manual
should be retained for the lifetime of the fireplace.
PRODUCT DESCRIPTION
The LEO 100 gas inserts are designed to be supplied with natural gas (NG) or liquefied propane gas
(LPG). The units may be available in four versions, depending on the type of glazing. The LEO 100
fireplaces are equipped with automation and security of the same type. Regardless of the model, how
it is connected to the gas system and the flue system is identical.
