Specification

Heat exchanger manufactured as standard from aluminised steel tube with swaged and expanded connections into a combustion gas collection box; no welding is used, minimising stress on components.
Four pass tubular heat exchanger, available upgraded to 409 or 316 stainless steel.
Individual in-shot burners per heat exchanger tube, fitted with Resistohm Helical Low NOx inserts capable of maximum continual 1300°C operation.
Suitable for use with G20 Natural Gas or G31 LPG with injector change.
Supplied with a modulating gas valve assembly as standard.
Supply fan airflow remains constant through the modulating operation, to achieve designed coverage and throw.
Casing designed for rigidity and low noise, with anti-vibration mounts securing the main fan assemblies.
Six top suspension points for ease of installation and additional security.
Easy access swing-out burner wiring panels.
NOx levels less than 70 mg/kWhr.
Casing protected by epoxy powder coat stove baked paint, RAL 7015.
Controlled by Powrmatic MC200 Optimised Start Control.
