One electrical panel per heater is required, unless
heaters are specified for multiple heater control
applications. On no account should more than one
heater be connected to a single time switch or
thermostat. The only exception to this is when a control
panel suitable for multiple heater applications is
supplied by the manufacturer, in which case the wiring
diagram supplied with the control panel should be read
in conjunction with the existing wiring diagram.
28
Any ancillary electrical items e.g. room
thermostats, time switches, remote panels etc,
must be wired into the heater electrical circuit in
accordance with the diagrams provided
When external controls operate to switch the
heater OFF, power to the heater should
remain to allow the fan to continue to operate
to sufficiently cool the heater thereby
preventing damage to the heat exchanger.
WARNING!
THESE HEATERS ARE NEUTRALLY

PRE COMMISSIONING CHECKS
The following pre-commissioning checks should be undertaken, having first ensured that the gas and electrical supplies
are turned off.
Check that all panels and fasteners are secure and in place.
Check that the heater is mounted safely.
Check that the flue is sealed, secured, and adequately supported.
Check that the fan is free to rotate, that the fan is secured to its shaft, and that the guards and fan assembly are all in
place and properly secured
Check that the heater is installed so that it is not tilted and remains square.
Check that the outlet louvres are set to offer minimum resistance to air flow.
