General Information.
This appliance must be installed in accordance with the rules in force. Consult instructions
before installations and use of this appliance. The unit 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 requirements.
The Continuum 11i (11i-fp) and Continuum 14i (14i-fp) are room sealed appliances.
Ventilation requirements of BS 5440 allow room sealed appliances to be installed in spaces
and rooms, including bedrooms, without ventilation.
If the Continuum 11i (11i-fp) or Continuum 14i (14i-fp) are installed in a compartment, it
must have the following amount of permanent ventilation:
- ventilation from compartment to room:
220 cm
2
at high level AND 220 cm
2
at low level; based on 10cm
2
/kW gross heat input;
- ventilation from compartment directly to outside:
110 cm
2
at high level AND 110 cm
2
at low level; based on 5 cm
2
/kW gross heat input.
The area given is the free area of the vent or equivalent free area for ventilators of more
complex design. Any space taken up by grille louvers should be subtracted from the total
area to find the free area of the vent. Windows and doors can not be considered ventilation
unless they are permanently fixed in the open position.
Please refer to IGE/UP/10 Part 1. Edition 2 page 17; for further information or contact Rinnai
UK.
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
requirements.
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 2.2m (horizontal or vertical) with coaxial flues.
Each 90° bend should be considered 0.2m of the total equivalent length.
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 is equal or exceeds 1.0m.
For flue runs requiring a drain the horizontal sections on the appliance side of any vertical
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 ingress of rain.
The drain pipe should be run in 22mm PVC, uPVC, or ABS pipe. The drain pipe MUST be
trapped. 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 can cause a slip hazard. It is the responsibility of the installer to
decide the best place.
