6.9. CONVERSION TO THE OTHER GAS
Adjustment and conversion to the other gas can be
performed only by the Authorized Service of the
manufacturer.
The rating plate with heater data for the currently used gas
should be always placed on the heater!
If other gas should be used to supply the heater, then it is required
to perform conversion. These operations can be performed only by the
authorized service of the manufacturer. The following conversions are
possible:
Heaters adapted for G20 gas can be converted to G27 and
G2.350 gas,
Heaters adapted for G31 can be converted to G30.
The conversion is based on the following operations:
Replacement of nozzle of primary burner with the one
suitable for the used gas,
Screw the bolt in to the burner injector,
Perform adjustment acc. to the instruction in 6.8 choosing
data from table for the required type of gas and model of
heater.
After conversion, it is required to stick one of the delivered rating
plates containing information on current type of gas.
6.10. INSTALLATION OF THE HEATER
Room heater should be installed in compliance with the
requirements of the currently applicable standards and
legal regulations and detailed regulations of the country
of destination. In Poland these conditions are regulated
by the Regulation of the Minister of Infrastructure of 12
April 2002 on technical conditions which should be
fulfilled by buildings and its location. (Journal of Laws
no. 75 of 2002 item 690 as amended).
If the DEFRO HOME VITAL heater is installed in rooms,
where particularly exposed people (such as children,
physically disabled or people requiring special
attention) may have contact with it, then it is required to
use additional protections. The protections are
intended to prevent contact of exposed people with
operating and hot equipment.
Fireplace system should be made of non-combustible materials
and its design should allow disassembly of the housing and heater
without any damages.
Installation of the room heater should obey the following safety
rules:
minimum distance 80 mm from side and rear of the non-
flammable materials,
minimum distance 400 mm from side and rear of the medium
inflammable materials,
minimum distance 800 mm from front wall, where the
medium inflammable materials cannot be located,
objects made of highly inflammable materials should be
located in distance minimum 2000 mm from furnace.
If it is not possible to maintain the above indicated distances, then
you should apply process and building measures to avoid fire hazards.
In case of contact with wooden wall or wall made of other inflammable
material, it is appropriate to insulate flue gas discharge pipe.
In case of floor made of inflammable materials, it is
appropriate to prepare a plane protecting the floor and
execute protection in accordance with the standards
applicable in the given country.
All surfaces of the equipment are working surfaces!
The room heater should be located on a substrate with suitable
load-bearing capacity. In accordance with the Polish Standards each
square meter of the floor slab in a single-family building should transfer
load of 150 kg. If this condition is fulfilled, the room heater
manufactured by DEFRO can be installed without needing to reinforce
the floor slab.
Nonetheless, if you are not sure about design of floor slab, where
the heater is to be installed, you should absolutely contact with building
designer to reinforce the floor slab or execute special structure
distributing the weight on larger area.
The system, where the gas-fired room heater is installed, should
be equipped with air supply and exhaust grilles of corresponding
surfaces. They are intended to ensure heat transfer between the
fireplace and the room. Supply grille should be located in bottom part
of the system to ensure supply of the cold air from the room. Exhaust
grille should be located in hood. For DEFRO HOME VITAL the size of
supply grille should be lower than 700 cm
2 and 900 m 2 for exhaust
grille.
The room, where the DEFRO HOME VITAL room heater has been
installed, should also be equipped with a supply/return grille to ensure
exhaust of gas in the case of leaks in the gas piping system. In the
system, the exhaust grille should be located in a place depending on
the fuel used in the fireplace.
For natural gas (NG) the grille should be located under the
ceiling.
For propane-butane (LPG) the grille should be located near
the floor, above the ground level.
Picture 22. Minimum distance that should be kept during installation of
the heater.
ATTENTION!!!
Lack of expansion joint may be a reason of equipment damage
what is connected with loss of the warranty rights.
6.11. FIRST START-UP
Perform leak-tightness test of gas connections to the gas
unit and from gas unit to gas nozzle during operation of the
equipment before first start-up.
First start-up should be performed by the fitter after checking
correctness of installation.
Odour of paint from the body will be released during the first
several hours of combustion. This is completely normal. You should
strongly vent the room at that time. Check tightness of joints once again
when equipment has been cooled down.
