2.2.5. Natural Gas and LPG Connection
(Device Category I2H, II2H3P)
Our combi devices are manufactured to be operated with methane
gas (G20) and L.P.G. Gas supply pipes should be equal to or higher
than 3/4"G combi connections. Prior to making the gas connection, a
thorough internal cleaning should be made to all fuel supply installation
pipe furnishings as possible wastes may distort smooth operation and
reliability of the combi. Only a mains gas supply can be used with the
combi (see the label located on the combi device). In case of any
conversions to the supply, changes should only be made to the combi
by an authorised professional. Also, in case of reduced pressure, the
network dynamic pressure (methane or LPG) used for supplying the
combi should be carefully controlled and will impact the boilercombi
strength. Ensure that gas valve connection is correct. Flammable gas
supply pipe should be able to supply correct adequate gas amount to
the boiler when the combi is at full power and be projected and sized
according to force and local gas company specification and instructions
in order to guarantee the device efficiency. Connection system should
comply with gas company legal regulations.
2.2.6. Flammable Gas Quality
The combi is designed to be used with pure fuel not containing any
foreign substances; therefore, required filter systems must be available in
the gas supply line (for ensuring purification of the fuel).
2.2.7. In Case of Using LPG Tank
LPG use is recommended for heat requirements over 24 kW. New LPG
stock tanks may contain settled gas residues (nitrogen) however, that
fouls the mixture assigned to that device and may cause abnormal
operations.
- Various alloy layers may be formed during transit of LPG gas in
tanks depending on mixture compositions. That causes a change in
heating power of mixture assigned to the device and may compromise
efficiency of the device.
2.2.8. In Case of Using Bottled Gas
• 300 mmSS pressurized hood should be used for LPG.
• 500 mmSS hood should not be used.
• 370 mmSS pressurized hood should be used for Propane.
• Do not place tubes in cold places at risk of snow or.
• Do not place tubes in hot placescontaining ovens or
• Do not make connections with single tubes and use
LPG collector set for double, triple uses.
• The distance between the collector and tube should
be maximum 125 cm.
• Copper pipe installation should not used for distances
longer than 125 cm.
• Hose connection ends should be tightened with clamp
and no other tools should be used.
• Gas installation rules with use of LPG tank and industrial tubes should
comply with local standards and to be performed by expert installation
teams and certified by the company undertaking the construction. In
case of failing to fulfil these conditions, combi will not be covered
under warrantee by Warmhaus Authorized Services.
