Page 36 of 67 A range of Balanced Flue Kits are available as optional extras for Camray 5 & Utility. Balanced Flues permit considerable choice of siting of the Boiler. Boilers may be installed in situations where no chimney exists, where the chimney is unsatisfactory or in outhouses. It is important that care is exercised in choosing a suitable location for the Boiler and Flues.
Page 37 of 67 Vertical Balanced Flues enables boilers to be installed in single storey outhouses or utility rooms where it may not be convenient for it to be sited near an outer wall. It may also be employed to exhaust vertically to avoid nearby windows or doors. Vertical Balanced Flues may also be preferred in cases where close proximity to adjoining houses or property dictates minimum exhaust noises. 5:3.
