10 FLUE GAS AND AIR SUPPLY SYSTEM
General
The water heater has a positive pressure flue system. For a single boiler, the available combined pressure drop
for the inlet and outlet system
is 200 Pa for the complete water heater range.
The CB water heater is for either using outdoor combustion air or for installation using indoor combustion air. All
combustion air is drawn from outdoors or indoor. All products of combustion are vented directly outdoors. The
Vent, and if applicable Air-Intake piping, must be piped to the outdoors. Under no conditions may this appliance
vent gases into a masonry chimney. The internal safety system shuts down the water heater incase the temper-
ature of the flue gasses becomes too high, after which the appliance will not run until re-started. Installations must
comply with local requirements.
The front cover closes the housing air-tight making sure air is only supplied by the vent air intake. Therefore, make
sure the front cover always has been placed in its position during operation of the appliance.
Till a pressure of 200 Pa, power will remain the same. Bigger resistance causes power decrease.
Notice:
•
Install all horizontal flue components with an angle of 3° downwards in the direction of the water
heater(roughly equal to five centimeters for every linear meter). When not installed accordingly, it may result
in condensate building-up in the flue gas tube, eventually causing component failure.
•
Wall flue terminals are generally used up to 80 kW. Using these terminals with larger capacities will give
unpleasant large condensate clouds.
•
When using a wall terminal, there is the possible risk of ice building-up on surrounding parts/structures, be-
cause the condensate will freeze. This risk must be taken into account during the design phase of the heating
installation.
•
Because the flue gases can have a low temperature, the water heater needs to have a high efficiency ap-
proved stainless steel or plastic flue system. These materials, including the gaskets, must be usable for pos-
itive pressure flue gas systems and have a temperature class of
T120. Meaning: the parts must be certified
for use at temperatures of minimal 120 °C
(See also warnings below).
Note:
In general, water heaters are certified with their own flue gas material. The water heater must be provided with
high efficiency stainless steel or PP flue gas components available at the M&G group or Burgerhout B.V. The
parts have to be qualified for a overpressure class P1 or H1 and a temperature class of T120 minimum.
For flue gas type B23, C13, C33, C43, C53 and C83 systems, use only flue gas and air supply parts of the
approved supplier M&G group (Muelink & Grol) or Burgerhout B.V and only the parts mentioned in the DoP (dec-
laration of performance): “No 001-MG-PP DoP” and No 001-MG-RVS DoP”. (With exception of O4 and O5) The
concerning DoP’s can be found at the website of Muelink & Grol https://www.mg-flues.com/certifications/
WARNING:
Before installing, read the installation manual(s) of the supplier of the flue gas and air supply parts
included with the parts. Manuals for parts supplied can be found at:
www.mg-flues.com/instructions/ and http://burgerhout.nl/documenten/handleidingen/
Undermentioned manuals for parts supplied by ECO HS are applicable:
- Regulations regarding flue gas systems PP(s)
- Installation instructions clamps: Checklist
- Installation instructions Skyline 3000
- Installation instruction Multiline PP (Cascade)
WARNING:
Never use aluminum containing flue gas pipes in these boilers.
