VENTILATION REQUIREMENTS
If the appliance is to be fitted in a confined space or
compartment it is a requirement that adequate ventilation
is provided to prevent the overheating of the boiler
controls. Aeration of 110 cm² will be required to the
compartment, in both high and low positions (see Fig. 2).
WATER SYSTEM
IMPORTANT: USE ONLY COMPRESSION FITTINGS WHEN
CONNECTING THE BOILER TO THE CENTRAL HEATING
SYSTEM.
ISOLATION VALVES MUST BE FITTED
The installation must comply with the requirements of the
following codes of practice.
BS 5449 Part 1 Forced Circulation Hot Water Systems
BS 7074 Part 1 Code of Practice for Sealed Water
Systems.
BS 7593 Treatment of water in domestic hot water central
heating systems.
The water system must be thoroughly flushed out.
Fill the system. Vent all air from system. Clear any air locks
and examine the system for water leaks.

POSITION.
The boiler is supplied with Dia. 22mm tail pipes at the
base of the boiler for connection to the heating system
(see Fig: 1). The boiler is also supplied with 15mm tail
pipes for connection to the DHW circuit (see Fig: 1).
The boiler must be installed using 22mm compression
fittings.
Model Minimum Flow Rate / Min
6kW 8 litres
9kW 10 litres
12kW 12 litres
Aztec boilers are approved for use on fully pumped open
vented systems and sealed systems. Where thermostatic
radiator valves are fitted it will be necessary to fit a bypass
to obtain minimum flow rates
.
IMPORTANT: IF MINIMUM FLOW RATES ARE NOT
OBTAINED THE BOILER MAY GO TO LOCK OUT ON HIGH
LIMIT THERMOSTAT.
System must be flushed out before adding inhibitor to BS
7593: 1992 treatment of water in central heating boiler.
IMPORTANT: THIS BOILER IS TO BE FITTED ON FULLY
PUMPED SYSTEMS ONLY.
Pump
WARNING! Risk of injury and damage to property!
Incorrect commissioning can lead to injuries to persons
and damage to property.
Commissioning by qualified personnel only!
Depending on the operating status of the pump or system
(fluid temperature), the entire pump can become very
hot.
Touching the pump can cause burns!
Operation
The pump is operated using the operating dial. By turning
the dial, different control modes can be selected, and the
delivery head or constant speed can be set.
NOTE: All settings are retained if the mains supply is
interrupted.
Domestic Hot Water
It is recommended the Hot water is timed to be on 15
minutes before water will be required at the tap.
The domestic hot water blending valve is factory set to
Minimum to give 45°C outlet temperature. This can be
adjusted as required but note that any increase will reduce
the volume of water available.
