Gas connection, Air supply and flue Introduction | A.O. Smith SGE

is

3.8 Gas connection

Warning

The installation should be carried out by an authorised installation engineer, in compliance with general and local regulations (1.3 "Regulations").

Caution

Make sure that the diameter and length of the gas supply pipe are large enough to supply sufficient capacity to the appliance.

See (D) in the installation diagram (3.5 "Installation diagram").

1.Fit a manual gas valve (10) in the gas supply pipe.

2.Blow the gas pipe clean before use.

3.Close the manual gas valve.

4.Fit the gas supply pipe to the gas control.

Warning

After fitting, check for leaks.

3.9Air supply and flue

3.9.1Introduction

This section covers the following subjects:

•Requirements for flue gas discharge materials

•Concentric connections

•Parallel connections

3.9.2Requirements for flue gas discharge materials

Warning

The installation should be carried out by an authorised installation engineer, in compliance with general and local regulations (1.3 "Regulations").

Depending on the approved installation types, there are several alternatives for connecting the air supply and flue gas discharge.

The appliances are approved for installation types B23, C13, C33, C43, C53 and C63.

The figure and table give information about these appliance types. For an explanation of the possibilities, please contact the manufacturer.
