INTRODUCTION USER GUIDE

USING THE BOILER

It is compulsory to have your system serviced every
year by a competent engineer. In the event of heavy
use of the boiler, it may require servicing on a more
regular basis than once a year. In this case, contact
your installer for advice.

Starting the burner

In conditions of normal operation, the burner starts automatically if
the temperature of the boiler is below the set point and goes off
when this value is reached.

Control panel

The user must not attempt to gain access to the
components inside the control panel.

1. On/Off switch

This turns the HeatMaster on or off.

2. Control thermostat - 60 to 90°C
When using the HeatMaster

®

as a hot water generator only, the

temperature can be set between 60°C and 90°C.
If the HeatMaster

®

is used for both hot water and central heating, the
control thermostat would normally be set at 80°C to achieve optimum
operating conditions.

3. Summer/Winter switch

This turns the heating pump

(if fitted)

on or off.

4. Manual reset high limit thermostat

If the boiler temperature exceeds 103°C this safety device will
activate and the high temperature indicator will light up. To reset ­first allow the boiler to cool to below 60°C, unscrew the cap and
press the reset button using a pencil or similar pointed device,
replace the cap. If the fault persists, turn the boiler off and call an
engineer.

USER GUIDE DESCRIPTION

OPERATING PRINCIPLE

The HeatMaster®is a high performance, direct fired hot water
storage heater, which has indirect heat transfer due to its Tank-in­Tank construction.

At the heart of the HeatMaster

®

is a stainless steel cylinder through
which the flue tubes pass. This is surrounded by a mild steel shell
containing the primary water (neutral fluid). The outer shell extends
down to the combustion chamber and even around the flue tubes.
The area of the heat transfer surface is therefore much greater than
that of standard direct fired water heaters.

A circulating pump fitted to the primary circuit moves the water
around the tank, heating it faster and maintaining an even
temperature across the primary jacket.

The burner, either gas or oil, fires onto the primary water which
indirectly heats the stainless steel cylinder containing the DHW. As
with all Tank-in-Tanks, this is corrugated over its full height and
suspended in the HeatMaster

®

by its hot and cold water

connections.

The cylinder expands and contracts during use and this, together
with the fact that cold water does not come into contact with the
intense heat of the burner flame, means that limescale buildup is
prevented.

This scale resistant feature, along with the corrosion resistance of
stainless steel, eliminates the need for sacrifical anodes.

The HeatMaster

®

has one very major advantage over other direct
fired water heaters - because it heats the DHW with a primary
circuit, this primary water can be used to provide central heating as
well.

By connecting two, three, four or more HeatMaster

®

together in a

module, most hot water and heating demands can be met.

Indeed, when used in conjunction with HR and Jumbo hot water
storage tanks the HeatMaster can supply even the largest hot water
requirement.

CONSTRUCTION FEATURES

Outer body

The outer body, containing the primary water, is made from STW 22
carbon steel.

TANK-IN-TANK heat exchanger

The ring-shaped inner tank with its large heating surface for
producing domestic hot water is built of Chrome/Nickel 18/10
stainless steel. It is corrugated over its full height by an exclusive
production process and entirely argon arc welded by the TIG
(Tungsten Inert Gas) method.

Combustion gas circuit

The combustion gas circuit is paint-protected and comprises:

• Flue pipes

Depending on output, HeatMaster®200 models contain
several steel flue pipes with an internal diameter of 64 mm.
Each pipe is fitted with a baffle of special steel designed to
improve heat exchange and reduce flue gas temperature.

• Combustion chamber

The combustion chamber on HeatMaster®models is entirely
water cooled.

Insulation

The boiler body is fully insulated by rigid polyurethane foam with a
high thermal insulation coefficient, sprayed on without the use of
CFCs.

Casing

The boiler is covered by a steel jacket which has been scoured and
phosphated before being stove enamelled at 220°C.

Important

• Keep vents free at all times.

• Do not store inflammable products in the boiler room.

• Do not store corrosive products near the boiler, such as paints,

solvents, chlorine, salt, soap and other cleaning products.

• If you smell gas, do not switch on the light or light a flame.Turn off

the mains gas tap at the meter and inform the appropriate
services immediately.

Access

The boiler room must be large enough to allow good access to the
boiler. The following minimum distances are required around the
boiler:

- front 500 mm

- side 100 mm

- behind 150 mm

- above 350 mm

Ventilation

The boiler room must have both low- and high-level ventilation,
in accordance with the local standards and provisions force.

The table below gives an example conforming to the Belgian standards.

Other countries should refer to their own standards.

Base

The base on which the boiler rests must be made of non-combustible
materials.

CHIMNEY CONNECTIONS

IMPORTANT
Boilers must be installed by an approved heating
engineer, in accordance with the prevailing local
standards and regulations.

The duct size may not be smaller than the boiler outlet
duct.

Typical boiler connection: B23

The boiler is connected to the chimney by a metal pipe rising at an
angle from the boiler to the chimney.

A flue disconnection piece is required.

This must be easy to remove to give access to the flue pipes when
servicing the boiler.

Note:
Regulations vary from country to country therefore
the table above is intended only as a guide.

Due to the high efficiency of our boilers, the flue gasses
exit at low temperature. Accordingly, there is risk that
the flue gasses could condense, which could damage
the chimney. In order to avoid this risk, it is strongly
recommended that the chimney be lined.

A condensation drain outlet must be fitted close to the
boiler to prevent condensation products from the
chimney running into the boiler.

To avoid condensation water running out of the
terminal, all horizontal flue runs must fall back towards
the boiler.

DRAINING THE BOILER

Water flowing out of the drain cock may be
extremely hot and could cause severe scalding.
Keep people away from discharges of hot
water.

Draining the heating circuit

1. Put the main switch on the control panel to OFF, cut the outside
power supply and close the gas or fuel supply valve to the boiler.

2. Close the isolating valves (4) or manually set the 4-way valve (1)
to “0”.

3. Connect a flexible tube to the drain cock (7).
Make sure it is properly connected.

4. Open the drain cock and allow the hot water to flow into the
drain.

Drain the hot water circuit

1. Turn OFF the on/off switch on the boiler control panel, isolate
external electrical supply, and turn off the gas or oil supply to the
boiler.

2. Release the pressure in the heating circuit until the pressure
gauge indicates zero bar.

3. Close stop cock (1) and turn off tap (8).

4. Open valve (9) then valve (10).

5. Let the water empty into the drain.

For the tank to be emptied, valve (9) must be situated

PLACING THE BURNER IN SAFETY MODE

When the burner is in safety mode, the safety indicator located on
the burner and the control panel lights up.

The red warning light indicates an operating fault. Wait one minute
before rearming the burner by pressing the button on the burner.

If the burner does not relight, call the service engineer after ensuring
that the fault is not due to a power cut or low oil in the tank.

PLACING THE BOILER IN SAFETY MODE

When the high-limit thermostat indicator light on the control panel
comes on: rearm the manual reset high-limit thermostat.

If the anomaly persists, contact your engineer.
