Inlet Grilles
The hot layer of air is dispersed across the whole ceiling so it is not necessary to install the inlet grille directly
near the fire flue. Inlet grille should be at least 2m from the flue in order to avoid excessively high temperatures.
- Choose the inlet grille location within the heat source room.
- Use the cardboard template supplied to cut the hole for the inlet grille.
- Before fitting the inlet grille, make sure the spring loaded arms are pushed upwards, as this will enable the
arms to spring outwards when the inlet grille is inserted in the hole.
- Regulate the amount of warmed air transferred out from the heat source room by adjusting the inlet grille’s
damper. Open the damper fully when installing the grille and adjust as required once the system is operating.
Installation
Fans
- Suspend fans more than 4m away, from bedrooms, where possible. This will ensure the quietest operation
possible and eliminate any resonance.
- Find the best mounting place in the roof cavity near to the Manrose touch screen controller location.
- Ensure the correct airflow direction is maintained when mounting the fan.
- Once suitable hanging points for the fan have been found, place the fan below its intended position and secure
the
duct.
- Connect the wiring and allow enough cable for when the fan is in its final suspended position.
- Suspend the fan approximately 400mm above the ceiling joists. A suitable junction box will be required to
connect the fan and mains supply.
