3.4 ELECTRICAL CONNECTION
The boiler is supplied with a standard 10 amp 3 pin plug for connection to a 240V 10 amp earthed GPO. The
boiler incorporates a 240/24 VAC transformer which supplies power to the control circuit only and must not be
used for any additional equipment. All equipment connected to mains power should be protected by an RCD
circuit breaker. The boiler has a 240 volt power supply for the pump electrical connection which incorporates the
pump run on feature. A terminal strip is provided for a 24 volt room thermostat.
If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or a suitably qualified
person in order to avoid a hazard.
If the Hurlcon Genus IV central heating thermostat is used the 24volt room thermostat connection must be bridged.
Also unplug the spade connector from terminal IN-1 on the small heatsaver PC board in the electrical box and
make safe. This is the middle terminal on the top side. See page 16.
3.4.1 GAS CONNECTION
A ¾”BSP FI is provided for gas line connection. An approved manual shut off valve must be installed in the gas
fitting line before the boiler so that the gas can be turned off and the boiler removed for servicing if required. The
gas shut off valve should be sized the same as the gas fitting line to prevent excessive pressure drop in the gas
pipe.
The gas fitting line should be installed by an authorised person and comply with local regulations and A.G.A. code
AGS5601. The gas line from the meter will usually be of a larger size than the gas inlet connection. Therefore a
reduction to the boiler connection fitting will be necessary. The reduction should be as close to the boiler as
possible.
Before using the boiler, test all connections for gas leaks using soapy water.
The boiler gas valve has a built in pressure regulator with a ⅛” pressure test point provided. On starting the boiler,
a manometer must be used and burner pressure checked against the boiler data plate. The gas valve regulator
may need adjustment to correct manifold pressure. Incorrect burner pressure may void warranty.

3.5 BOILER DIMENSIONS
3.6 INDOOR INSTALLATION
This boiler is designed for outdoor use only. If the HW130 - 160 Boiler is to be installed indoors, a dedicated
indoor model with special flue kit is available.
3.7 HEATING PIPE SIZE & LAYOUT
The flow & return connection sizes of 1”BSP on the boiler are not necessarily the correct pipe sizes for the
heating system. It is important that the pipe sizes are correctly calculated before installation.
Hurlcon recommend a two pipe system with the pipes sized according to the flow requirements and length
of runs with a maximum water velocity of 1.5 M/s.

Notes
1. An automatic heating bypass valve should be fitted to maintain adequate flow rate through the boiler when
thermostatic valves are fitted and or when the majority of radiators are required to be turned off for long
periods of time.
2. Any pipe work that is in an unheated area such as under the floor or in the ceiling space should be suitably
insulated to prevent heat loss and possible freezing of the pipes.
3. The pipe work should be graded to facilitate the elimination of air at the highest point and the draining of
the system at the lowest point. Provide air bleeds and drains at these points.
3.8 SIZING OF PRESSURE VESSEL
If the total water capacity of the heating system is greater
than 60 litres then an additional pressure vessel should be
fitted. An approximate figure can be calculated from the
following table. An additional tank can be fitted at a
convenient location on the system if required.
4.0 COMMISSIONING
4.1 STARTING BOILER
Fill system with water and purge all air from system and pump.
Purge gas line of any air and wait five minutes for gas to clear.

TO TURN GAS OFF TO APPLIANCE
Turn off all electrical power to the appliance.
Turn off gas tap in gas line prior to boiler.
5.1 ENERGY SAVING TIPS
During extended periods of non use, turn the boiler off.
Set up a regular program of preventative maintenance for the boiler. Check heat exchanger, controls,
burner operation etc.
For areas where there is a danger of freezing, water should circulate through your boiler even if the
heating is off.
5.2 MAINTENANCE
It is recommended that the following items are professionally checked at least every six months and at the
beginning of every heating season.
Examine the flue outlet or termination cowl. Make sure there are no obstructions to the flow of air to, or
flue products from, the appliance.
Visually check the main burner and pilot flames. If the flame appears yellow, the burner should be cleaned
by a qualified service technician.
Keep the boiler area clear and free of combustibles and flammable liquids. Chlorine should not be stored
in the vicinity of the boiler. Chlorine vapours, when drawn through a boiler, can rapidly cause corrosion of
the heat exchanger.
Keep the boiler area free from garden refuse and debris. This will help prevent insects nesting in the unit
and ensure extended life and reliability of your boiler.
5.3 CONTROL SYSTEMS
5.3.1 DESCRIPTION – On / Off models

5.3.2 TEMPERATURE DISPLAY
The temperature display indicates water temperature in the outlet (flow) of the boiler. Therefore the pump
must be operating for an accurate water temperature to be displayed.
Water temperature can be set between 55˚C to 90˚C. (35˚C to 55˚C floor heat). To select your desired
water temperature press the up or down button repeatedly until the desired temperature is reached.
To prevent rapid cycling of the boiler, the thermostat has an inbuilt time delay which prevents the boiler
from turning on for two minutes after the set point has been reached. If the time delay is activated, the
symbol “L” will be displayed. This is part of normal operation.
The thermostat can be set to temperatures between 55˚C to 90˚C. (35˚C to 55˚C floor heat). It also
incorporates several safety features including a 100˚C high limit function to prevent overheating. On
simultaneous shut down of the circulating pump and boiler, the water within the boiler may exceed the set
temperature for a short period. If the pump and boiler are restarted during this period, the thermostat will
go into a standby mode and prevent the boiler from relighting until the temperature within the boiler has
dropped below the set temperature.
Should the thermostat fail to stop the boiler at the set point or at 100˚C, there is a manual reset
temperature limiting safety device designed to lock the boiler out and prevent further heating. A lock out
condition is indicated by the symbols F1 or F2 on the display. To reset a lock out condition, turn the
controller off for five seconds. An F2 condition will first require the mechanical safety device to be reset. To
do this, remove the top front access panel and locate the high limit thermostat at the outlet of the heat
exchanger, press the red button. If the boiler has cooled sufficiently, a positive “click” should be heard and
felt.
5.3.3 FAULT INDICATION
Under fault conditions the thermostat display will indicate a set of alpha numeric symbols to indicate the status of
the boiler. The meaning of each symbol and action to be taken are listed as follows:
