Installation

Gas pipework installation

The installation must conform to all standards and regulations.

The gas supply pipework and gas stop valve to be installed near the unit must be sized so as to assure the gas pressure is sufficient at the unit inlet when operating at full load.

CAUTION! Should the pressure at the unit valve gas inlet be higher than 0.035 bar, an expansion valve must be installed.

The pipework must be self- supporting and the final connection to the burner must be made by a flexible pipe. Provide a dust protection (filter) upstream the unit connection.

CAUTION! The gas pipework must not exert any stress on the burner gas connection.

Note: Expansion valve must be adapted to the type of gas used:

•G 20 : 20 mb

•G 25 : 25 mb

•G 31 : (Propane): 37 or 50 mb

Gas leak check procedure

 

1. Vent the gas line

 

2. Gas supply line pressure test:

close valve 4 and open valve 2

 

3. Leak-check the gas pipe

 

Look for gas pipe leaks using

 

"Typol", "1000 bulles" or a similar

 

product. Do not use soapy water.

 

WARNING! Never use an open

 

flame to check for gas leaks.
