Double-hinged door for reduced plantroom space and easy maintenance<br />
Instead of a normally hinged door, the <strong>Mini</strong>-3 has a proven double hinged door allowing<br />
problem-free extraction and swivelling out of long burner heads, typically associated<br />
with low NOx burners.<br />
Opening and swivelling out is also no longer hindered by adjacent walls or other burners<br />
in a multi-boiler system. (See space requirments below).<br />
The opening direction of the double hinged door can be easily reversed on the boilers.<br />
Regular boiler cleaning will contribute <strong>to</strong>wards the lowest possible energy consumption.<br />
The <strong>Mini</strong>-3 double-hinged door enables the boiler <strong>to</strong> be opened for cleaning without the<br />
need for the burner <strong>to</strong> be dismantled.<br />
A further advantage of the double-hinged door is that, in contrast <strong>to</strong> traditionally hinged<br />
doors, it makes uniformly even contact on all sides, thereby achieving absolute gas<br />
tightness. It is therefore not necessary <strong>to</strong> adjust the hinges <strong>to</strong> give a gas tight seal.<br />
Space requirements<br />
The boiler should be sited on a flat, level and fireproof floor / base. A plinth is not<br />
necessary as the boiler sits on a channel base.<br />
Wherever possible space should be left around the boiler <strong>to</strong> enable all parts <strong>to</strong> be examined<br />
and the cubicle casings <strong>to</strong> be fitted or removed easily.<br />
Back clearance is required for the system connections, flue connections and access <strong>to</strong><br />
the cleaning door.<br />
Front clearance is required <strong>to</strong> swivel the boiler door, including burner, by 90 o , (standard <strong>to</strong><br />
the right, optional <strong>to</strong> left).<br />
Space requirements <strong>to</strong> right when right hinged 80mm (plus burner length).<br />
Space requirement at front where possible should allow for extraction of retarders etc.<br />
(nominally 500mm from boiler door).<br />
Controls<br />
The standard control panel incorporates:<br />
n flow thermometer<br />
n temperature control thermostat<br />
n on/off switch<br />
n high temperature limit thermostat<br />
with manual reset<br />
n excess temperature indica<strong>to</strong>r<br />
(The panel can be <strong>to</strong>p or side mounted depending on the boiler model selected) For<br />
combination boilers additional temperature control and temperature indication is included.<br />
Each control panel is equipped for two stage burner operation for matching<br />
seasonal load requirements on low fire rating option. TopTronic controller(s), volt free<br />
contacts and an hours run meter can be supplied as optional items. If TopTronic controller(s)<br />
are required the control panel, as shown, is utilised.<br />
TopTronic control<br />
The TopTronic control system brings<br />
<strong>to</strong>gether Hoval’s considerable experience in the field of heating & hot water control,<br />
<strong>to</strong>gether with a high performance micro-processor controls package. The result is a<br />
simple user-friendly operating platform that controls individual heating and hot water<br />
systems and optimises energy conservation.<br />
Databus connections<br />
Optional TopTronic controllers can be fitted directly in<strong>to</strong> the boiler control panel (as shown)<br />
enabling control of up <strong>to</strong> two variable temperature, one constant temperature and one<br />
calorifier primary circuits. These are linked <strong>to</strong>gether by databus connections. Please<br />
refer <strong>to</strong> our separate TopTronic leaflet for further information.<br />
Electrical supply<br />
230V 50 Hz single phase mains supply should be connected <strong>to</strong> the boiler control panel via<br />
a fused isola<strong>to</strong>r.<br />
Delivery and assembly<br />
The <strong>Mini</strong>-3 & <strong>Mini</strong>-3H heating only boilers are supplied fully assembled and cased. Delivered<br />
shrink wrapped on a pallet for ease of handling on site. Control panels & burners are<br />
supplied separate for fitting by the installer.<br />
The <strong>Mini</strong>-3H combination units are supplied with boiler, burner, calorifier, pump & pipework<br />
and control panel separate for site assembly.
