2 ATAG XL Commercial Boiler The most efficient boiler, with the lowest lifetime costs Key features The ATAG XL commercial boiler range is available with outputs from 70kW to 960kW. There are three boilers in the range, incluing the XL70, XL110 an the XL140 - all of which can be installe in-line or back to back as wall mounte or free staning cascae arrangements. Available in 70kW, 110kW & 140kW inputs XL boilers can be installe in a cascae arrangement of up to eight boilers, proviing maximum output with exceptionally low emissions an all in a compact footprint.

3 Quality Assure The finest components Heat Exchanger Efficiency is at the heart of the XL ATAG Commercial boilers utilise the highest quality components to ensure maximum urability an prouct life. The XL boiler utilises trie an teste technology, with the patente OSS heat exchanger elivering class leaing efficiencies of up to 110% - making the ATAG XL the most efficient boiler on the market. Fully moulating brushless fan for quiet operation Automatic air vent fitte to highest point of the heat exchanger The stainless steel heat exchanger comprises multiple specially engineere pipes to ensure irect heat transfer an high levels of conensation. The incline mounting position of the heat exchanger ensures quick isposal of the conensate, with the smooth pipes an specialise assembly preventing contamination. An aitional benefit of the XL esign is the own-firing arrangement of the burner, which further prevents contamination, while acting as an insulator above the heat exchanger. The esign of the XL's heat exchanger also allows for an increibly low maintenance frequency of every 4 years or 16,000hrs. Durable materials Moulating gas valve The use of urable materials an the stainless steel OSS Electrical connection rail with push fit/release connections heat exchanger results in minimal maintenance intervals an a maximum operating life of the XL boiler. 316L Stainless Steel OSS Heat exchanger with 5 year warranty Fully moulating, A rate energy efficient pump Electronic MMI cascae controller BUS communication cable pre wire for ease of installation 04 05

4 The Ecological Choice The most efficient boiler, with the lowest lifetime costs Efficiency * 99.3% Gross110.3% Net The XL boiler range utilises the patente OSS Stainless Steel, long life heat exchanger to provie maximum efficiency for the lifetime of the boiler. By combining the fully moulating premix burner technology with the inbuilt electronic moulating pump an energy management system, the ATAG XL boiler is one of the most efficient boilers on the market toay. With class leaing efficiencies valiate by Gastec at 110.3%, XL boilers can theoretically recover 99.3 pence for 1 of gas use. The high efficiency of the boiler also greatly reuces the amount of flue gas emissions ie, CO 2 an NOx. The XL boiler also achieves the maximum BREEAM points for low NOx with emissions of less the 30mg/kWh across the range.

5 Boiler Configurations Flue Configurations XL boilers are quick an simple to install with multiple boiler sizes an configurations possible. This ensures they are perfect for a wie range of plant rooms, especially where space is at a premium. The XL boilers are equippe with connections for both flue gas an air inlet (parallel tubes) which allows both open an room seale arrangements. Moular system 5 With options for wall mounte in-line, free staning in-line an back-to-back arrangements, the ATAG XL boiler offers a wie range of moular installations. The orering an purchasing of materials are simplifie with all the necessary flow, return an gas connection pipework inclue, along with the isolation valves. Moular installations from 2 to 8 boilers are possible, by combining together the appropriately size components neee to connect either 2 or 3 units. Examples of some of the moular boiler installation possibilities: ATAG XL 3 Boilers free staning back-to-back ATAG XL 2 Boilers free staning in-line Open system The boilers' combustion air can be taken from the ventilate plant room via the air filter (require separately), with the flue ischarge connecte together into a cascae heaer. Room seale system The combustion air can be ucte into the boilers by a cascae heaer system, with the flue ischarge connecte together into its own cascae heaer.

6 Matche low loss heaers Easy Assembly Designe for simplicity The DN65 an DN100 prefabricate low loss heaers are esigne for a neat, quick an time saving installation. ATAG Commercial also supplies air an irt separators an osing pots to protect the boilers an increase the longevity of the boiler plant. As the Original Equipment Manufacturer (OEM), ATAG Commercial recognises that to prouce the very best proucts requires a eep unerstaning of the entire process; from esign an evelopment through to final installation an customer support. ATAG has specifically esigne the XL commercial boiler for easy installation, by combining pre-fabricate hyraulic heaers an boiler support frames that seamlessly fit together an save-valuable installation time on site. A low loss heaer moel is selecte epening on the capacity of the assembly. The DN65 version is suitable for outputs up to 452kW, while the DN100 size heaer can be utilise up to 960kW. These compact heaers may be positione on either the left or right han sie of the cascae assembly. Each heaer is supplie with ajustable feet, air vent, connection gasket an bolt set, an incorporates a connection for a water pressure gauge or temperature sensor. The low loss heaers can either be positione in line with the main pipe work heaers, or with the use of optional ben sets at a 90 angle.
