Low Fire Adjuster (Governor Type)
Each module must be analysed and adjusted separately.
This is undertaken by inserting the analysers probe in to the silicone sampling tube
secured to the top of each module and sealed with a black plug. If fluctuating
figures are obtained the flue gas analyser should be inserted directly into the module
flue spigot once the silicone tube has been temporally removed.
(Taking care not to dislodge the
grommet)
Each module must be set to the following combustion figures.
