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.

 

Hanging Strap

Fan Casing

Fan spigot with Insulated Duct fi tted

Fix end of strap to roof joists using a nail or screw 
as shown below. Ensure strap is folded down as 
shown for strength.

-  This double strapping method will prevent the strap from slipping during handling and operation.

H

old buckle in one hand and thread approximately 100mm of blue strapping through 

the underside of buckle.

Feed strapping through to fold back and down to loop over plastic prong then feed 
back through buckle. 

Place strapping around load to form a loop. Using the free end of strapping, repeat 
first step to form two looped straps over prongs of buckle.

With load situated in desired position tighten strapping by adjusting and tightening 
threaded ends through buckle.
