Connecting condensate drain

2.3.12
• Connect the condensate drain outlet  to a suitable waste
water drain point using acid resisting pipe work (i.e. - ¾"
overflow). To enable the siphon in the boiler to be removed
/ serviced, the connection should not be a permanent one
(i.e. "push fit" system or a "tundish" immediately below the
boiler).
• To prevent the risk of freezing connect the condensate into
an internal vertical soil pipe using a tundish (air break) c/w a
min 75 mm water seal trap.
• If the condensate pipe has to run externally make sure
this is done by realizing the shortest possible route, and
increase the diameter to at least 1¼" or insulate it with
weather resistant insulation.
• The drain should slope at least 3 cm per meter, with a maxi-
mum horizontal length of 5 m.

• If connecting into an internal discharge branch (i.e. sink
waste etc) the connection must be down stream of the
existing waste trap.
• Fill the boiler siphon with water before operation, to prevent
flue gasses discharging into the room.

• The condensate drain must be connected in accordance
with current regulations.


Before installation, check that the gas meter has sufficient
capacity for the demand. Remember to consider the
consumption of all household appliances.
2.4.2
The Avanta boiler is suitable for both natural gas and propane
firing. For propane a kit with restrictor is required.
The boiler is supplied as standard set for natural gas (G20),
therefore the following procedure must be carried out
BEFORE the boilers are fired and commissioned for the first
time on propane:
Fit restrictor (not included with boiler)
Adjust the fan speed (see par. 2.10.8) and
Adjust the gas/air ratio (see par. 2.10.3).
