Modulating Premix burner:The UltraGas® adapts its output on a smooth curve to precisely match the required heat demand with up to 6:1 turndown. (12:1 on Twin units). This improves fuel consumption and reduces the carbon dioxide emission.
Enhanced effi ciency with single pass condensing heat exchanger:The single pass stainless steel UltraGas® has a premix burner downfi ring into a vertical water surrounded tube nest made up of high effi ciency aluFer® tubes. The extended heating surface and corrosion resistant properties of the aluFer® tube ensure enhanced heat transfer and peak condensing performance. Two return connections for high and low temperature circuits ensure optimum condensation. Low hydraulic resistance and no minimum fl ow rates due to the large water volume further enhance the design.
Choice of systems:The UltraGas® boiler can be used on open vented or sealed systems. All models can operate with either natural gas or propane.
Low acoustic power and pressure levels:The UltraGas® is surprisingly quiet. A variable speed fan and a sophisticated noise containment system ensure up to 50% lower noise emissions.
Fresh air inlet connection:UltraGas® 125-1440D boilers have a connection at the rear to accept a ductedfresh air supply for room-sealed applications. An optional room-sealedkit should be specifi ed for each boiler where required (kit excludes freshair ducting to boiler). Twin boilers do not require the optional kit.
Easy maintenance guaranteed: Numerous, well thought out details ensure low operating costs and high convenience of maintenance in the UltraGas®. All the components are easily accessible, simple to clean and can be rapidly and cheaply replaced in the event of a fault.
Controls / TopTronic controllers:The control panel is ergonomically designed for ease of operation andis housed within the front of the boiler casing. A TopTronic controller is supplied as standard to control a boiler circuit, mixed circuit and calorifi er primary pump. Integrated frost protection, outdoor sensor for direct/mixed circuit compensation of operating temperature, pump control with overrun facility, temperature and fault diagnostic indication all come as standard. Upto fi ve boilers can be linked together to provide sequence control. Additional features such as extra mixed circuit, solar and solid fuel can be added with software keys. UltraGas® 70-1300D have room for an additional TopTronic. An electronic control module controls all the safety aspects of the burner together with modulation control.
BMS control:The operation of each boiler can be controlled via a 0-10V input signal (by the addition of an optional interface module). This allows control of either the burner fi ring rate or the boiler operating temperature set point.
The UltraGas® is kind to the environment: Through the revolutionary UltraClean® combustion system, emissions from the UltraGas® meet the strictest target and limit values anywhere in the world.
Assembly and delivery:UltraGas® (15-90) boilers are supplied fully assembled and cased.They are delivered shrink wrapped on a pallet for ease of handling on site. Models (125-720 and 250D-1440D) are delivered with the casings and control panel packed separately for fi tting by the installer.

Record level of effi ciency of more than 109%: Low temperature boilers convert about 93% of the calorifi c value of gas into usable heat. With the UltraGas®, this limit is raised considerably by using condensing technology. One of the main products of combustion gases is water (as steam) and in the conventional boiler the heat within this is lost through the fl ue. This is not the case with the UltraGas®; in condensing operation the hot steam is cooled back down to 40-50°C thus releasing the latent heat of vapourisation for use in the heating system. The result is as much as a 15% increase in the amount of usable heat which dramatically increases the boiler effi ciency.
Hoval aluFer® - the formula for maximum condensation:The internationally patented aluFer® tube is a Hoval innovation in advanced heat transfer technology. It is constructed from an inner aluminium fi nned surface, heat shrunk within an outer stainless steel tube and has exceptional heat exchange characteristics. The effi ciency of the heat transfer is attributable to the following factors: ● High heat conductivity of the aluminium which is ten times greater than that of steel. ● Internal fi nned surface of the aluminium tube enlarges the heat
exchange surface fi vefold. ● Inner surface of the tube is divided into eight fl ow channels to create
maximum turbulence and heat exchange.The construction of the condensing exchanger is such that the aluFer® tubes are arranged vertically, therefore the condensate formed does not remain on the heat exchange surface but runs downwards to the collection reservoir and drain.
Advanced control system Hoval TopTronic®T:All Hoval UltraGas® boilers are equipped as standard with the user friendly digital Hoval TopTronic®T control system. With a central turn / push button and 7 keys the required heating programs can be activated and the temperatures regulated. A clear LCD display shows important operating information in fi gures and text. With a 0-10 volt interface module providing the option of setpoint or fi ring rate the control panel can be integrated with modern building management systems.

Average Hoval UltraGas® NOx emissions of less than 40 mg/kWh:Following additional recent extensive independent emissions testing to DIN EN 676 it is stated by GWI (GasWarme Institut e.V.) that all UltraGas® boilers have average NOx emissions of less than 40 mg/kWh. Accordingly the UltraGas® pre-mix gas fi red condensing boiler can be considered to achieve, across the range of outputs from 15kW to 1440 kW, the maximum BREEAM credit rating relating to NOx emissions. All fi gures are dry and at 0% excess oxygen.
Greater effi ciency through modulation:The controls of the UltraGas® adapt the output of the burner on a smooth curve to match the required heat demand. Through this modulating mode of operation, the downtimes of the burner are signifi cantly reduced. The advantages of this are that loss of cooling is reduced, which leads to energy saving, while the working life is increased because the burner is not constantly fi ring at full rate. It also benefi ts the environment because the peak emissions which occur in the starting and shutdown phase of the burner are substantially reduced due to the less frequent starting of the burner.
The UltraClean® combustion system: The UltraGas® is impressive for its uniquely low nitrogen oxide and carbon monoxide emission values. The secret of low emission combustion lies in the specially designed and patented UltraClean® radiation burner and in the perfect gas/air mixture. On the surface of the UltraClean® combustion cylinder, there is an almost fl ame-free combustion of the gas-air mixture. The low, fl at fl ame pattern remains “cooler” than the gas fl ames in conventional combustion technology. In this way, substantially lower nitrogen oxide and carbon monoxide emission values can be achieved and as a result the environment is spared a signifi cant amount of harmful waste gases. Natural gas or propane can be used on all models of UltraGas®.
Optimised stratifi cation with separate high and low temperature returns:A key feature of the boiler is that it has two return connections, one directly into the boiler and one into the aluFer® condensing heat exchanger. Heating systems with higher return temperatures enter the boiler connection whilst the return from low temperature systems are connected to the condensing unit. The low temperature return need only be as small as 5% of the total, thus the designer can optimise the potential for condensing. No minimum fl ow rate is required other than at startup and pump overrun.
Twin UltraGas® units are also available:Single UltraGas® condensing boilers are available in a range of nineteen sizes with outputs ranging between 15 and 720 kW. For larger outputs or if multiple boilers are required, the UltraGas® can be provided as a twin boiler system. This gives a further twelve sizes with outputs ranging between 250 and 1440 kW.
The twin units are supplied as standard with a fl ue header (1).
To enhance the standard twin unit, optional items are available 1 :
● Flow header with motorised shut off valves (2). A return header can be used if the motorised valves are not required.● High temperature return header (3).● Low temperature return header (4).

Flue design UltraGas® 15-90
• An adapter with sample points must be used (fi tted to the boiler fl ue outlet connection).• The fl ue gas is very cool and saturated with moisture so there will be very little or no buoyancy to pull the gases up the chimney.• The burner fan assists with the evacuation of the fl ue gases so there may be slight pressurisation of the fl ue.• It is permissible for the condensate from the fl ue system to drain back through the boiler.• Horizontal fl ue sections must be inclined back to the boiler (3° minimum) to prevent condensate remaining in the fl ue.• Flues must be designed to meet all current regulations / standards.• See Technical data section for fl ue gas mass fl ow rates, temperatures and usable fan overpressure.• Please refer to ventilation requirements below.• The tables below are for guidance only.
Maximum fl ue lengths
The above fi gures include for one 93 degree bend. Additional 93 degree bends will have the effect of reducing the length by 2.5 metres and 45 degree bends will reduce the length by 1.5 metres. The fl ue lengths stated will have no effect on the boiler output.

• A minimum temperature class T120 fl ue can be used if fi tted with an over temperature device.• Single wall fl ues may be used as it is not necessary to keep the fl ue gas temperature high.• The fl ue gas is very cool and saturated with moisture so there will be very little or no buoyancy to pull the gases up the chimney.• The burner fan assists with the evacuation of the fl ue gases so there may be slight pressurisation of the fl ue.• Flues must be leak proof against condensate and suitable for pressurised fl ue gases.• It is permissible for the condensate from the fl ue system to drain back through the boiler.• Horizontal fl ue sections must be inclined back to the boiler (3° minimum) to prevent condensate remaining in the fl ue.• If combustion air ducting is used this should be the same size as the fl ue.• Flues must be designed to meet all current regulations / standards.• On installations with multiple boilers into a single fl ue the fl ue system must be designed to prevent any back circulation of fl ue gases into the plant room (fi tting air shut off dampers enable this criteria to be easily met - see accessories).• See Technical data section for fl ue gas mass fl ow rates, temperatures and usable fan overpressure.• Please refer to ventilation requirements on separate page.

Figures are based on the fl ue entering the vertical at 90°, for 45° entry or if 45° bends are used longer fl ue lengths may be possible.* With 5 bends or more the usable overpressure of the fan must be reduced by 30% and a flue calculation done.
