1. Installation Requirements
Storage, Unpacking & Handling
This boiler is delivered in two sections for safety and
ease of handling. Store both the Top (heat engine)
and the Bottom (cylinder) under cover in dry conditions.
Remove the Promax HE Store unvented Accessory Kit
from above the heat engine to reduce lift weight. (The
front and top panels can also be removed if required -
see Fig. 1).
Handholds are provided at the top rear of the heat
engine and will assist with removing it from the
transport tray. Handholds are provided at both sides
and underneath the cylinder.
Use a handling device e.g. sack truck, to manually
move either section over long distances. Trucking must
be done from the rear. Take particular care to avoid
damaging outer panels or programmer.
These items should be lifted and handled by two
people. Stooping should be avoided and protective
clothing worn when necessary. Carrying and lifting
equipment should be used as required for moving Top
and Bottom to where they will be assembled and
installed..
Determine beforehand whether the Top and Bottom
should be assembled to enable the complete unit to be
moved into position, or whether to fit the cylinder and
then lift the heat engine into position.
The Top has 2 downward facing dowel pins which
provide accurate location on to the cylinder. Take care
to avoid trapping hands and fingers during assembly.
Take great care when manoeuvring the boiler into its
final location and avoid twisting movements of the
body.
Do not attempt to carry the complete boiler
as the Top is only dowelled to the Bottom.
Dispose of packaging in accordance with
environmental guidelines.
1.1 Gas Supply
Entry holes are provided in the base and via knockouts
in the side panels.
This boiler requires a natural gas supply of 2.6 cubic
metres per hour. A 22 mm gas inlet connection is
provided at the front and gas supply pipework of not
less than 22 mm diameter should be run to the boiler.
The meter and supply pipes must be capable of
delivering this quantity of gas in addition to the demand
from any other appliances in the house and must be
governed at the meter.
The gas installation should be in accordance with the
relevant standards. In GB this is BS 6891. In IE this is
the current edition of I.S. 813 "Domestic Gas
Installations".
The whole of the gas installation must be checked for
soundness and purged in accordance with, in GB, BS
6891 and in IE, I.S. 813 “Domestic Gas Installations”.
1.2 Electricity Supply
The boiler requires a 230V ~ 50Hz single-phase 3A
fused electrical supply. External wiring must be correctly
earthed, polarised and in accordance with relevant
regulations/rules. In GB this is the current I.E.E. Wiring
Regulations. In IE reference should be made to the
current edition of the ETCI rules.
Detailed wiring instructions are given in Section 10.
Power consumption is approximately 90 - 166 W.
WARNING: THIS BOILER MUST BE EARTHED
In the event of an electrical fault after installation of the
boiler, preliminary electrical systems checks must be
carried out i.e. Earth Continuity, Short Circuit, Polarity
and Resistance to Earth.
1.3 Location of Boiler
The boiler must not be sited outside or in any outhouse
where it could be exposed to the weather.
The boiler must be installed on a flat floor capable of
supporting the weight of the unit when full of water – up
to 250 kg for the 150 litre model.
It should be sited to minimise the length of flue and to
avoid long hot water pipe runs.
The extended flueing capability enables the boiler to be
sited well away from an outside wall, thus installation in
a first floor cupboard or compartment, basement, utility
room or kitchen are all feasible locations.
The location chosen must permit the provision of a
satisfactory external flue termination. The location must
also provide adequate space for servicing and air
circulation.
