8.8.5 TYPE C
53
When installing the heater as a Type C
53
appliance, it should be noted that the terminals must not be
installed on opposite sides of the building or closer than 500mm apart (centre to centre).
To install a Type C
53
terminal or air inlet, the procedure for either a Type C
13
(horizontal) or a Type C
33
(vertical)
terminal should be followed noting that the annular space of the terminal should be sealed off
8.9 FLUE TERMINAL GUARDING
If a horizontal flue terminal is to be fitted less than 2 metres from ground level or in a location where it can be
touched from a window, door or balcony, a terminal guard must be fitted. An approved terminal guard, Lochinvar
Part No. FTG0001 is available; please contact Lochinvar Limited for further information.
The terminal guard is constructed from plastic-coated mild steel and is suitable for use on condensing appliances
only. The guard should be installed centrally around the terminal ensuring a gap of at least 50mm between the
guard and terminal is maintained.
9.0 AIR SUPPLY
The following information is based on single water heater installations only. If more than one water heater is being
used,
BS6644 should be consulted to calculate the necessary requirements.
9.1 COMBUSTION VENTILATION
When used as a Type C appliance, provided sufficient clearance is provided, ventilation for combustion is not
necessary as the combustion air is ducted directly from outside.
