IMPORTANT PRE-INSTALLATION NOTES

By Fitting this Aztec Classic boiler, you agree:

• The Boiler has been received in good condition.
• You have carried out a heat loss calculation and are sure that this boiler is suitable.
• You have carried out a load and voltage test to determine the correct size of breaker to be used.
• You meet the requirements of the appropriate Building Regulations

Before installation, it is imperative that the following guidelines are heeded to ensure the trouble-free and efficient operation of the boiler:

Ventilation and Siting

When siting the boiler in a confined space it is essential that adequate ventilation be provided. This will ensure that air can circulate freely around the appliance keeping down the ambient temperatures. Refer to Ventilation requirements (Page 12) for further details.

Ensure that the area surrounding the boiler is kept free of items which would impede the good ventilation of the appliance (e.g., towels, linen, etc).

When siting the boiler, consider the potential requirement for future servicing. Enough space should be provided at the front of the boiler to enable an engineer to adequately service and/or replace items such as the PCB or heat exchanger. Space should also be available for the removal of the front casing panel. Please refer to siting information (Page 11) for clearance dimensions. The boiler must be sited vertically and away from strong magnetic fields.

Power Supply and Wiring

The power supply to the premises must meet the minimum requirements of the unit being installed, with special attention paid to the supply current, cable size, and RCD recommendation. The supply voltage to the appliance must never drop below 207 Volts.

System

Isolation valves must be fitted on both the flow and return pipe work. These are useful as from time to time the boiler may require draining of water, and the lengthy drawing-off process can be avoided by the astute placement of these valves. Ensure that any isolation valves are open before first use, and that the system is full of water

IMPORTANT

General Information:
To keep your boiler running efficiently DO NOT OBSTRUCT OR COVER any ventilation air inlet on the appliance or the compartment where it is installed.

To keep the casing clean, switch ‘OFF’ the boiler at the electrical supply, and simply wipe with a damp cloth. DO NOT use abrasive cleaning fluids as this may damage the stove enamel paintwork.

The water system must be thoroughly flushed out with cold water without the pump in position. Refit the pump and fill the system. Vent all air from the system. Clear any air locks and examine the system for water leaks.

IMPORTANT: ENSURE ALL SERVICE VALVES ARE IN OPEN POSITION.

Ensure boiler is fitted with flow pipe at the top and return pipe at the bottom.
The boiler is supplied with 22mm tail pipes top and bottom for connection to the system.
The boiler must be installed using 22mm compression fittings both top and bottom

The AZTEC ranges of boilers are low water content boilers so always require a good flow rate (see below chart).

Aztec boilers are approved for use on fully pumped open vented systems and sealed systems. When fitting on a sealed system a 3 bar safety valve must be fitted to the system, where thermostatic radiator valves are fitted it will be necessary to fit a bypass to obtain minimum flow rates.

IMPORTANT: IF MIN 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 7593:2019, Treatment of Water in Central Heating Boiler.

IMPORTANT: THIS BOILER IS TO BE FITTED ON FULLY PUMPED SYSTEMS ONLY

Sealed Water System Requirements

The installation must comply with the appropriate requirements of the current issue of BS 4814, BS 5449, BS 6798 and BS 7074 Part 1 and 2.

THE INSTALLATION ENGINEER MUST BE REGISTERED AS A COMPETENT INSTALLER.

Safety Valve

A safety valve set at 3 bar must be fitted with the drain routed to the outside of the building. The drain must not discharge above an entrance or a window or any public access area, be clear of any electrical fittings and positioned so that any discharge can be seen.

Expansions Vessel Capacity

A diaphragm type expansion vessel, conforming to the current issue of BS 4814. The expansion vessel must be connected to the systems at a point close to the inlet side of the circulating pump. The expansion vessel volume depends on the total water system volume and the initial system design pressure. For any system an accurate calculation of vessel size is given in the current issue of BS 5449 and BS 7074 Part 1.
The water content of the boiler is given in the Technical Specification. Note: A higher initial design pressure requires a larger Volume expansion vessel.

The charge pressure must not be less than the static head of the system that is the highest point of the system above the expansion vessel.

Capacity of Expansion Vessel

Where design information is not complete the following chart can be used for selecting the size of the vessel.

System Temperature

The normal running temperature of the system is 75°C, if a fault was to occur then the safety device would allow the system temperature to rise to 95°C. It is recommended that this figure be used in the calculations of vessel size.

Connection of the Expansion Vessel

The expansion vessel should be connected in the neutral part of the system this being the return pipe work close to the boiler, refer to sealed system pipe work layout drawing.

Pressure Gauge

A pressure gauge must be permanently fitted in the system covering a range from 0 to 4 bar. Position where it can be seen when filling the system.

System Makeup

Provision can be made by pre-pressurisation of the system via a temporary hose connection and through a double check valve (non-return) and stop valve. There must be no permanent connection to the mains water valve supply even through a non-return valve.

Inhibitor

If using an existing system take care to drain down the entire system including the radiators, then thoroughly clean out before fitting the boiler. Attention is drawn to the current issue of BS5449 and BS7593 on the use of inhibitors in central heating systems.

Drain Tapping

A drain tapping must be provided at the lowest point of the system, which will allow the entire system to be drained.

Magnetic Boiler Filter

To be fitted in the return pipe work close to the boiler. Failure to do so will invalidate the warranty.

Multiple Boiler Installations

Important

Where a greater output is required, more than one boiler can be used in the same system. However, if installing a Circulating pump with a higher power demand, the PCB circuit protection fuse may not be adequate. The pump could be wired using a relay. See wiring instructions (Page 17) for further details.

The boilers must be fitted side by side using common flow and returns. For each additional boiler fitted, it is recommended that the pipe work is increased in size and the pump set to deliver the combined flow rates. The circulating pump will be connected to one of the boilers or via the relay.

We strongly recommend the positioning of isolation valves on the flow and return pipe work of each boiler, as there may be a need to isolate one or more during servicing.

Sealed System

Open Vent
