4.3.1 Fitting the flue pipe
The flue pipe socket is located on the back of the air heater. Flue pipes must
be sealed. Use seamless, aluminium pipe or equivalent. Follow pipe
manufacturer's instructions (see figures 4 & 5).
Table 7 Flue pipe socket size (dia mm)
4.3.2 Installing a guard on the combustion air inlet pipe for power vent (Type B installations)
The combustion air inlet socket is located at the back of the heater. When installed as a type B appliance,
protect the inlet by fitting an access guard on the socket. Do not block this socket as it supplies combustion
air for the burner (see figure 4).
4.3.3 Fitting the combustion air inlet pipe for balanced flue (Type C
installations)
The combustion air pipe attaches directly to the inlet socket at the
back of the heater. Air inlet pipes must be sealed. Use seamless
aluminium or equivalent. Follow the pipe manufacturer's installation
instructions. See typical installations in figure 5.

4.4 Gas connection
Do not use the appliance gas supply to
balance or support any part of the
appliance .
Figure 6
Connection to a gas network may only be carried out by
appropriately qualified persons. The gas installation must
comply with the rules in force using materials appropriate for
gas installation.
To facilitate servicing, the air heater must be fitted with an
approved gas service tap and union fitting or union tap
adjacent to the appliance.
The inlet gas supply line must be installed so as to permit the
access door to be opened and to allow removal of the slide
out burner assembly.
Air heaters suspended by flexible suspension materials or drop
rods must be connected to the gas supply using an approved
flexible connector. Sufficient slack must be provided in the
connection to allow for movement of the appliance. Use a
flexible connector of suitable size to reduce the pressure drop
and the possibility of gas flow noise.
