SECTION 4: CRITCAL CONSIDERATIONS
4.1 Ventilation
It is important to ensure that there is adequate air
circulation around the heater to supply air for
combustion, ventilation and distribution in
accordance with local and national codes.
4.2 Gas Supply
It is important that the gas supply pipe is sized
correctly to provide the inlet pressure as stated on
the heater data plate. The gas supply pipe and
electrical connections must not support any of the
heater's weight.
4.3 Electrical Supply
A permanent 230 V 50 Hz 1Ø electrical supply is
required at the main electrical terminals. The heater
also requires suitable energy controls in accordance
with
Section 10.
4.4 Flue
Choose heater siting to allow for the proper location
of the flue. Each heater must be fitted with an
individual and correctly sized sealed flue system
(
See Page 13, Section 7).
No other appliance may be connected to the flue.
For room sealed installation, the air intake must be
the same size sealed system and the flue/air intake
must terminate at an approved concentric wall or
roof terminal.
