1. General information
The Instruction manual is destined to acquaint the user with operation of the solid fuel fired boiler. Prior to commencing installation and operation of the
boiler each user should acquaint oneself precisely with the operation instruction manual of the boiler, feeder and controller. The instruction comprises
recommendations concerning boiler installation and its operation. Incompliance of the user with regulations and recommendations included in this
instruction manual released the boiler manufacturer from all his obligations and guarantees. The boiler should be operated by an adult person only.
Full satisfaction from the boiler performance can be accomplished only using the proper fuel.
1.1. Application
Galaxia KWE type steel heating boilers with a screw conveyer feeder are designed for water central heating systems of detached family houses. The top
temperature of water in the boilers does not exceed 85°C. The boilers belong to the low temperature water boilers operating in open type installations and
do not require registration at the regional Office of Technical Inspection. The boilers are designed for operation in gravitational central heating installations or
with open system enforced circulation, having protections compliant with the requirements of PN-91/B-02413 standard. The boilers may operate in closed
installations provided devices used for relief of excessive heat are installed (relief-cooling valve of DBV type or a cooling coil).

Table 1 - Estimated selection of the boiler heat output for the building
Presented values of room heated area for the boiler output are approximated ones. The boiler should be selected individually for the building by a designer
or installer on the basis of the energy certificate.
1.2. Fuel
Boiler operation depends, to a large extent on fuel quality. In order this operation was trouble-free the fuel should comply with the below requirements:

It is allowed to apply substitutive fuels in the Galaxia KWE boilers (e.g. brown coal). While burning substitutive fuels one should consider changing of the
boiler heat output approximately proportional to the calorific value. Combustion of substitutive fuels may result in shortening of the boiler life span.
CAUTION! Coal must be dry! Maximum fuel moisture 4.4%.
