FLUE REQUIREMENTS - INSTALLING
The flue must be installed by a competent, authorised person. It is the installer’s responsibility to ensure that the unit has been installed to all current local require- ments.
Ensure that the flue terminal and hot water outlet connection cannot be touched by children. The flue must be clear of obstructions and shrubbery.
Flue Length.
The flue Total Equivalent Length is limited to 6.5m. Each 900 bend should be consid- ered 0.5m of the Total Equivalent Length. The maximum number of bends is 3.
Separate instructions are provided with the flue detailing the installation of the flue parts.
Flue pipes must include a condensate drain if the total flue height exceeds 1.5m. There is a special condensate drain collector piece available through Rinnai or your supplier. For flue runs requiring a drain the horizontal sections on the appliance side of any verti- cal runs should slope towards the appliance, and the flue should be bracketed to prevent sagging. If the terminal is horizontal it should slope gently to the outside to prevent in- gress of rain.
The drain pipe should be run in 22mm PVC, uPVC, or ABS pipe, copper is not recom- mended. The drain pipe MUST be trapped. A trap with pipe is available from Rinnai or your supplier.
Although the flue and appliance have been specially designed to prevent condensation in the flue for short runs (under 1.5m) care should be given to the placement of the terminal to prevent risk in the unlikely event of condensation. Condensation water can cause burns, and during winter could cause a slip hazard. It is the responsibility of the installer to decide the best place.
