Viessmann VITOGAS 100 Technical Data Manual

90 to 240 MBH/26 to 70 kW 5167 462 v1.5 02/2011 Vitogas 100 with boiler stand beside Vitocell-V 100 domestic hot water storage tank Vitogas 100 Technical Data Manual Model Nos. and pricing: see Price List Vitogas 100 GS1 Series – residential, fully assembled boiler Natural Gas-/Propane-Fired, Single-Stage Boiler cast iron sectional construction atmospheric, fully premix burner Heating input: 90 to 240 MBH 26 to 70 kW

to its compact dimensions, the Vitogas 100 is ideal for installation in closets and alcoves. Apart from saving space, the Vitogas 100 is economical in terms of energy consumption with reduced emissions. The benefits at a glance:
High operational reliability and a long service life due to special high-grade gray cast iron with lamellar graphite and a low thermal load on the heat exchanger surface.
Clean combustion due to atmospheric premix burner with super-stoichiometric premixing: NOx < 27.9 ppm (air-free), CO < 9.2 ppm (air-free). The Vitogas 100 therefore meets the toughest emission requirements in North America, such as California regulations (SMAQMD).
Economical and environmentally friendly operation via modulating boiler water temperatures. Annual fuel utilization efficiency (A.F.U.E.) of up to 85.6 %.
Intermittent pilot ignition system provides soft, quiet and extremely reliable ignition.
Compact dimensions – therefore suitable for installation in a boiler room, a utility room or even in an open living area.
Problem-free transport into difficult-to-access boiler rooms due to light weight and compact design. Heat exchanger surfaces of special high-grade gray cast iron for high operational reliability and a long service life 5167 462 v1.5
