4.0 Installation

 

 
4.1 

Location

 

 
4.1.1 

Ensure the structural elements of the building are 

adequate to carry the weight of the appliance and 
its ancillary components, i.e. the flue system, and 
that the surface on which the heater is located is 
level in all plains and non-combustible. 

  

4.1.2 

Sufficient space must be maintained around the 
heater for servicing and the appliance should not 
be sited where it may suffer damage, e.g. forklift 
trucks or traffic. 

 
4.1.3 

The location must also allow for fitting an 
effective flue system and for adequate clearance 
for the air supply, return air, circulation, gas and 
electrical supplies whilst providing good and safe 
working access. 

 
4.1.4 

When moving the heater it is strongly advised 
that the lifting eyes are used.  Adequate 
clearance from combustible materials must be 
maintained between the appliance and its flue 
system. 
 

 

4.1.5 

The horizontal cabinet heater (HCHE) must be 

suspended as illustrated in figure 5.  When 
suspending the horizontal units, ensure the 
structural elements of the building are adequate 
to carry the weight of the appliance and its 
ancillary components (e.g. : flue system, duct 
system, ...).  Unit may only be suspended by 
means of a frame on which the unit must be 
installed. It is strictly forbidden to make use of the 
fixation eyes to suspend the unit! 

 

When unit is installed as a ducted heater, the 
duct connections must be installed as described 
in § 4.5.3. Ensure the dimensions of inlet & outlet 
duct are the same.  
When the air intake is installed without a grille at 
the backside of the unit, ensure that a protection 
grille IP20 is installed to avoid the penetration of 
objects into the blower compartment.
