INTRODUCTION
Minimiser FF 30-80
are fully automatically controlled, wall
mounted, low water content, balanced flue, fanned super
efficient condensing gas boilers. They are spot-rated to
provide central heating outputs of 8.8 kW (30,000 Btu/h) to
23.4 kW (80,000 Btu/h).
Due to the high efficiency of the boiler a plume of water vapour
will form at the flue terminal during operation.
The boiler casing is of white painted mild steel with a drop-
down control pod door. The controls pod, also of white painted
mild steel, has fixed sides and a removable bottom panel.
The boiler thermostat is located behind the controls pod door.
The heat exchanger is of aluminium.
Note.
These boilers cannot be used on systems which include
gravity circulation.
The boilers are suitable for connection to fully pumped, open
vented or sealed water systems. Adequate arrangements for
completely draining the system by provision of drain cocks
MUST be provided in the installation pipework.
OPTIONAL EXTRA KITS
Programmer Kit
