Clearance of at least 800 mm is required at the front
(service side) of the boiler. However, we recommend a
clearance of 1 m. A clearance of at least 400 mm above
the boiler and at least 300 mm on both ends (800 mm
if the instrument panel is rotated to face the short end).
An isolating gas main cock must be installed near the
boiler, within hand's reach.

7.3 Flue gas discharge and air supply

7.3.1 General

The Remeha Gas 310 ECO is suitable for both conven-
tional room ventilated or eccentric room sealed opera-
tion.
Room sealed terminals should comply with the Gastec
QA-requirements for vertical outlet constructions.
Any horizontal pipework in the flue gas discharge sys-
tem should slope towards the boiler.
Horizontal pipework in the air supply system should
slope towards the supply opening and may require a
drain point at the low point.
Care should be taken when siting flue exit positions as
a vapour plume will be visible when the boiler is opera-
tional (flue gas temperature will be less than < 77°
resulting in the water vapour condensing out on contact
with the air).

7.3.2 Classification due to discharging flue gases

Classification according to CE:
Type B23: Conventional room ventilated appliance with-
out draft diverter. Air supply from boiler room; flue gas
discharge on roof.
