Instructions for Use
4. Open a hot water tap, check that water flows, then close it.
5. If you are in any doubt about the boiler being filled with water
contact your installation/servicing company or the local gas
company.
6. Check that the electrical supply to the boiler is ON at the
external isolator.
7. Check lockout light, refer to boiler safety cutoff reset button.
8. Set the switch “B” to 1 situated on the control fascia.
9. Set the summer / winter button “J”, light “L” or “K” will
illuminate.
10. Set “C”, clock/timer (if fitted) and any remote controls as
required.
11. Check the lights “D” and “E” are illuminated on the control
fascia.
Close the controls cover door.
In certain circumstances, a surge in water pressure may cause
the appliance to operate momentarily, this will be indicated by
the pump starting and the fan speed increasing. This is quite
normal.
Domestic Hot Water Temperature
The sanitary water temperature control knob “M”, see diagram
4, will control the desired temperature of the water until the flow
exceeds the capability of the boiler to give the required
temperature rise.
Then the temperature is determined by controlling the hot water
flow from the tap ie:
reduce flow - increase temperature
increase flow - reduce temperature
NOTE : The mains incoming water temperature in the winter is
lower than in the summer.

Maintenance and Servicing
To ensure the continued efficient and safe operation of the
appliance it is recommended that it is checked and serviced as
necessary at regular intervals. The frequency of servicing will
depend upon the particular installation conditions and usage,
but in general once a year should be enough.
If this appliance is installed in a rented property there is a duty
of care imposed on the owner of the property by the current
issue of the Gas Safety (Installation and Use) Regulations,
Section 35.
Servicing/maintenance should be carried out by a competent
person in accordance with the rules in force in the countries of
destination.
To obtain service, please call your installer or Heatcall (Glow-
worm’s own service organisation) using the telephone number
behind the controls cover door.
Please be advised that the ‘Benchmark’ logbook should be
completed by the installation engineer on completion of
commissioning and servicing.
All CORGI Registered Installers carry a CORGI ID card, and
have a registration number. Both should be recorded in your
boiler Logbook. You can check your installer is CORGI registered
by calling CORGI direct on :- 01256 372300.
Clearances
The boiler requires a clearance in front, below and at the sides
of the casing for safety, servicing and maintenance access, see
diagram 2.1.
Protection Against Freezing
The boiler has a 2 stage built in frost protection. Provided power
and gas are available and there is adequate pressure in the
system, if the water temperature within the appliance falls below
10
o
C approx. the pump only will come on. If the water temp
continues to fall to 6
o
C approx. the main burner will fire at min
rate until the water in the appliance is greater than 15
o
C approx.
This is a separate function to any remote frost protection fitted.
