PRELIMINARY INSTALL GUIDE
2. INSTALLING A FIREPLACE INSERT WITH A WATER JACKET AND COOLING COIL (CONTINUED)
The water system must be equipped with a water overflow tank in compliance with the Australian &
New Zealand Standards concerning open system installations. For closed system installations, safety
devices are required as per your local regulations concerning technical conditions of buildings and
location thereof as well as a diaphragm expansion vessel, safety valve (DN25 safety valve with 1.5 bar
opening pressure is recommended) and a temperature valve used to control water flow through the
cooling coil in order to collect excess heat.
3. WATER JACKET ASSEMBLY GUIDELINES
To ensure the satisfactory, safe and problem-free use of the fireplace insert with a water jacket, the
following guidelines are recommended. It is highly important that the water jacket be connected by
authorised and experienced professionals. The same principle applies to flue gas outlet pipes. Failure
to comply with these instructions may result in an unsafe installation. We recommend only licenced
personnel should install this system. To improve the functioning of Multivision Hydro in the open
system, we recommend the application of an open overflow/buffer tank with a float and automatic
water replenishing system to ensure smooth operation of the system and protect the water jacket
against damage due to inadequate water level.
IMPORTANT: You must not establish a fire in the fireplace insert before filling up the water jacket with
water. Otherwise any damage resulting from use against the recommendations of the manufacturer will
void the product guarantee.
The insert casing must provide access to the hydraulic fittings of the water jacket through maintenance
access panels. It is recommended that the circulation pump of the system switch on by means of a
thermostat mounted on the water jacket. Once the set temperature of the water in the jacket is reached,
e.g. 50˚C, the thermostat switches the pump; otherwise when the fireplace is not used, the pump
remains idle.
We also recommend the installation of a temperature and pressure gauge on the water system. All
components of the water system, i.e. the pump, valves, and filters should be mounted by means of
quick connect fittings to facilitate easy disassembly in the event of a defect and repair work. Two
cut-off valves shoud be installed so the filter can be cleaned before, during, and after the peak period.
This will effectively protect the circulation pump from defects. The filter should be cleaned when the
system is not in operation. An air separator should also be installed to remove air bubbles and prevent
the radiators from becoming air-locked. All types of radiators designated for open and closed central
heating systems can be used with the Seguin Multivision Hydro 80.
