4. Setting the gas/air ratio at full load
The Avanta boilers are suitable for both natural gas and propane firing (restrictor
required for propane not supplied). The boilers are supplied as standard set for
natural gas (G20), therefore the following procedure must be carried out BEFORE
the boilers are fired and commissioned for the first time on propane:
- fit restrictor (instructions supplied);
- adjust the fan speed (for procedure see
par. 2.10.8 , for values
see table 06 and table 08 );
- adjust the gas/air ratio (for values see table 06 and table 08 ).
