1.2.4. Dimensions and Connections

1.2.5. Natural Gas and LPG Connection (Device Category I

2H

, II

2H3P

)

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 studious internal 
cleaning should be made to all fuel supply installation pipe furnhishings as 
possible wastes may distort smooth operation and reliability of the combi. 
It should be controlled whether the gas distributed from the main line is as 
envisaged (see the table on the combi device). 

In case of having differences, an intervention should be made on the combi 
and converted to other gas type (consult our authorized services in case 
of gas change). Also, in case of being inadequate, the network dynamic 

pressure (methane or LPG) to be used for supplying the combi should be 
controlled regarding the impact on combi strength and difficulties possible 
for the user. Ensure the correctness of gas valve connection. 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 local gas company specification and instructions in order to guarantee the 
device efficiency. Connection system should comply with legal regulations.

1.2.6. 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).

1.2.7. 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 pauperises 
the mixture assigned to that device and cause abnormal operations.
- Various alloy layers may be formed during stocking LPG gas in tanks
depending on mixture compositions. That causes a change in heating power 
of mixture assigned to the device and changes efficiency of the device. 

1.2.8. 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 at cold places having risk of snow for preventing frost 

during winter months.

• Do not place tubes in hot places containing ovens, fireplaces for preventing 

dangers!

• Do not make connection with single tube 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 shall not be commissioned by
Warmhaus Authorized Services.
