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.

BOILER ROOM
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.

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.
