The manufacturer's notes must NOT be taken,
in any way, as overriding statutory obligations.
IMPORTANT. These appliances are CE
certificated for safety and performance.
It is, therefore, important that no external
control devices, e.g. flue dampers, economisers
etc., are directly connected to these appliances
unless covered by these Installation and
Servicing Instructions or as otherwise
recommended by Unical in writing.
If in doubt please inquire.
Any direct connection of a control device not
approved by Unical could invalidate the
certification and the normal appliance warranty.
Notes.
To obtain the gas consumption:
a. For l/s divide the gross heat input (kW) by
C.V. of the gas (MJ/m³).
b. For ft³/h divide the gross heat input (Btu/h)
by C.V. of the gas (Btu/ft³).
