GAS SAFETY (INSTALLATION AND USE)
REGULATIONS 1996 (AS AMENDED).
It is the law that all gas appliances are installed by a registered
person, in accordance with the above regulations.Failure to install
appliances correctly could lead to prosecution. It is in your own
interest,and that of safety,to ensure that the law is complied with.
WARNING:It is essential that the appliance is correctly earthed.
An electricity supply of 230Y-50Hz is required, fused at 3 Amp.
Read these instructions carefully before attempting to operate the
appliance.Comply with all applicable warnings.Do not interfere
with any sealed components,and use the appliance only in
accordance with these instructions.
The Halstead Ace and Ace High are fully automatic,wall
mounted, fan assisted balanced flue gas combination boiler for
use with natural gas only.The Ace High has a higher domestic hot
water heat output and provides a higherRow rate.
The appliance incorporates a microprocessor based, fully
modulating gas control system with direct burner ignition.
The Ace High provides both central heating and instantaneous domestic
hot water at outputs between 11 kW (37,500 BTU/h) and 30 kW
(102,000 BTU/h).The Ace provides both central heating and
instantaneous domestic hot water atoutputs between 8.8 kW
(30,000 Btu/h) and 24.0 kW (82,000 Btu/h).
Heat output is controlled according to demand (in both domestic
hot water and central heating mode) by the modulating gas
control.The appliance always gives priority to domestic hot water
supply.
The appliance incorporates frost protection.However this is not
operational when the main switch on the appliance is in the off
position or the electrical supply to the appliance is isolated.
An electro/mechanical 24hr time clock is fitted as standard.
Gas Consumer Council
The Gas Consumer Council (GCC) is an independent organisation
which protects the interests of gas users. If you need advice, you
will find the telephone number in your local directory under 'Gas .
In the event of a demand for hot water, the appliance will detect
water flow and initiate the ignition sequence.The fan (and pump)
will start, and the boiler will light.
If the hot water draw off rate is near to the design flow rate, the
appliance will run continuously at full output until the tap is either
turned off or the flow rate is reduced, in which case the heat
supplied will reduce accordingly to maintain a steady
temperature.
Hotwater is made available almost immediately at the appliance
outlet, but the final temperature and time taken for the hot water to
reach a tap depends upon the thermostat setting, the rate at which
water is drawn off,and the diameter and length of the pipe
between the boiler and tap.
When the tap isturned off, the appliance will revert to heating
mode if there is a demand for heating, otherwise the burner will
be extinguished until the next demand for hot water.
Please ensure that you have a Logbook supplied with your
appliance.This Logbook should be completed by your
installer(s)to verify that the correct installation and commissioning
procedure was followed.
Failure to complete the Logbook may result in difficulties should a
problem rise with your appliance during the guarantee period.
This Logbook forms part of the industry's Benchmark code of
practice for the installation, commissioning and servicing of central
heating systems.
All CORGI Registered Installers carry a CORGIID card and have
a registration number.Both should be recorded inyour Logbook.
You can check your installer is CORGI registered by calling
CORGI on 01256 372300
1) Check thatthe gas and electricity supplies are ON and that the
water isolation valves underneath the appliance arealso turned
ON.
2) If heating is required, first turn the main switch to the Heating &
Water position and the Heating temperature control to maximum
(fully clockwise). Ensure that the clock is set to an ON period
(see diagram) or set the clock over-ride switch to the ON
position. Turn up the room thermostat (if fitted).The boiler will run
through a series of tests then the burner will light and the three
green LEDs - Power On, Heating and Burner On - will be
illuminated.
3) Hot water will be supplied as soon as any Domestic Hot Water
tap is turned on and the green Hot Water LED will be
illuminated. If necessary, adjust the temperature of the hot water
using the Hot Water temperature control.
NOTE: Priority is always given to Domestic Hot Water supply.
If the burner fails to light, ignition lock-out occurs. In the event of
ignition lock-out the red safety Lockout LED will be illuminated.To re-
set the appliance and initiate a further ignition attempt it is necessary
to turn the main switch through to the Reset position (spring return to
setting).
If the red safety Lockout LED illuminates again after another ignition
attempt, another fault may exist. In this case, press the overheat re-set
button situated underneath the LHS of the appliance and reset the
appliance as detailed above.If the fault persists, consult your installer
or service engineer.
TO TURN THE APPLIANCE OFF: For short or long periods:
Switch the clock over·ride switch to the OFF position.
Note: Frost protection is fitted as standard, but this can only function
if the gas and electricity supplies are maintained and the main switch
on the appliance is left in the hot water or heating and water mode.
The clock can be switched to the off setting.. f either of these services
is to be isolated during a period when frost is likely,the water
circuits must be drained.
The following minimum clearances must be maintained for
installing and servicing the appliance, 200mm top and bottom,
5mm each side and 450mm in front.
If the appliance is installed in a compartment it must not be used
for storage purposes. Any ventilation provided for the appliance
during installation MUST NOT be blocked and a periodic check
must be made to ensure that vents are free from obstructions.

The following additional features are included in the
appliance specification:
Whenthe appliance cycles on it's central heating control setting,a
slow cycle device operates.This allows the water to heat up
slowlythus preventing rapid cycling of the burners.
Providing thata power supply is maintained,The pump will
operatefor at least 20 seconds every 23 hours (regardless of heat
demand)to prevent pump seizure during periods when the
appliance is not used.
Thisdevice prevents the burner from igniting if there isinadequate
water flowthrough the main heat exchanger.If the Power On LED
flashes, thisindicates failure of the flow switch and your installer
or service engineer should be contacted.
Use only a damp cloth and mild detergent to clean the appliance
outer casing. DO NOT useabrasive cleaners.
It is essential that these instructions are strictly followed for the safe
and economical operation of this appliance.
The appliance is a fan-assistedbalanced flue gas boiler and
