3.4 Air supply 

Figure 2c: Combustion air and flue pipe sockets, Type B 

 

It is important to ensure that  
there is an adequate air supply  
at all times for both 
combustion and heating 
requirements. Modern 
constructions involve the 
greater use of insulation, 
improved vapor barriers, and 
weather proofing. This practice 
means that buildings are 
sealed much tighter than in the 
past.

The combustion air supply for a power vented 
gas fired air heater (Type B installation) can 
be affected by lack of air supply. Natural 
infiltration may not be adequate. Use of extract 
fans aggravates this situation. It is important 
to ensure that there is an adequate air supply 
at all times. Reliance on doors and windows is 
not allowed. Always ensure that an adequate 
inlet for fresh air for combustion is provided 
sized to suit the total installation of any 
combustion apparatus. 
Fit an access guard to the combustion air inlet 
on the back of the heater and take appropriate 
action to ensure that it remains unblocked. 
See figure 2c. 

 

WARNING: This model air heater is 
installed as a type B application and is 
designed to take air for combustion 
from the space in which it is installed. 
Do not restrict the combustion air 
intake. 

 

 
3.5 Air distribution 

 

Follow recommended practice for building air 
distribution.

 

The following notes are of particular 
importance: 

  "Where free blowing air heaters are installed it 

must be taken into account that heated air is 
buoyant when it leaves the appliance, therefore, air 
patterns within the space being heated will modify 
the air throw pattern achieved.

 In 

building 

having low heat loss where single heaters are required to 
cover a large floor area and in buildings with high ceiling 
heights, air re-circulation fans e.g. Maximizors may be 
fitted to ensure even heat distribution and minimize 
stratification. Care should be taken to avoid impeding air 
flow with storage racking, partitions, etc." 

 
 

 
3.6 Electrical supply 

 

Wiring external to the air heater must be 
carried out in accordance with the rules if 
force and by appropriately qualified persons. 
A constant 230 Volt 50 Hertz single phase 
fused electricity supply with neutral link is 
required. All heaters and controls must be 
earthed. A lockable isolator with contact 
separation of at least 3.0 mm on all poles 
should be installed adjacent to the appliance 
and within reach of any person working on the 
heater.  
When a number of heaters are to be 
connected as part of a single installation each 
heater must be provided with a separate 
isolator. 
The electrical connection to the air heater is at 
the back of the appliance. The final connection 
must be made in the terminals provided in the 
control compartment.  
Follow the wiring diagram provided with the air 
heater. 
Electrical supply cable conductor size should 
be 1.5 mm. Fit the cord grip supplied with the 
heater. The length of conductors between the 
cord grip and the terminals must be such that 
in the event that the cable becomes taut the 
line conductors do so before the earth 
conductor. 
 
 

3.7 Gas supply

 

 

LCSC-3E air heaters are designed to operate 
on either natural gas (G20) or propane gas 
(G31). Refer to the specifications in section 2 
of this document and to the data plate for 
details of supply pressures. 
The gas meter and gas service must be 
checked by the supply undertaking to ensure 
that they are adequate to deal with the total
