Material And Installation - REMEHA Quinta 30 Technical Information

Room sealed installations:
It is unnecessary to provide separate combustion air to the room/compartment as this
is supplied direct to the boiler via the concentric or eccentric system and the room sea-
led horizontal or vertical terminal unit.
Additional ventilation will be required to the room/compartment in accordance with the
British Standards (compartment ventilation).
For maximum flue/air inlet length, see table in Par. 7.3.5.
For installations where supply and discharge points are in two different pressure zones
(eccentric only), please contact Broag Technical Dept. for further details and advice.
See also Par. 7.3.6.
NOTE: the boilers can be installed on a flue dilution system, but must have a total flue
break to avoid boiler controls being affected by the flue dilution fan pressures. For full
details please contact Broag.

7.3.3 Material and installation

Flue gas discharge:
Rigid single walled: stainless steel (316), aluminium or plastic (to comply with building
regulations).
Flexible: stainless steel (316).
Construction: all joints and seams should be gastight and watertight with the horizontal
runs graded towards the boiler to allow condensate free drainage to the boiler
The flue outlet should terminate with reduction cone and bird guard only (chinamans
hat or GLC type terminals etc. should not be used).
Use vertical flue terminal MG 87973 for classification C33 and use horizontal flue ter-
minal MG 87996 for classification C13. Flue material for classification C6 must comply
EN 483 annex N and must always be in draft condition.
Air supply:
Single walled, rigid or flexible: aluminium, stainless steel and plastic (to comply with
building regulations).
