9.4 Fill Condensate Trap with Water
WARNING
Asphyxiation hazard! Fill condensate trap
before starting boiler to avoid combustion
products escaping boiler. Failure to follow these
instructions could result in death or serious
injury.
!
•
To fill the condensate trap pour water into exhaust
vent until water begins to flow through the siphon.
• Visually inspect the siphon to ensure it is full with
clean water.
• During operation check condensate trap to ensure it
drains properly.
Note
Condensate trap must be manually filled with
water at initial start up.
•
Boiler is fitted with automatic air vent positioned on
pump Vent and is fitted with adjustable sealing cap.
See Figure 9-1.
•
Open central heating flow and return valves. Spindle
is flat in-line with valve.
•
Open fill point valve on filling system until water
begins to flow. To aid venting boiler drain may be
open until water flows out. Close drain as soon as
water appears.
• During initial system air purge open valve connected
to top left of heat exchanger. Open four (4) full
turns counterclockwise until steady stream of water
is witnessed. Close fully turning clockwise with no
tools needed. See Figure 9-1.
• Systems using radiators to remove air - Vent each
radiator in turn, starting with lowest in the system.
• It is
IMPORTANT
the pump is properly vented
to avoid running it dry and damaging its bearings.
Unscrew and remove cap from center of pump. Use
screwdriver. Rotate exposed spindle about half turn,
replace cap.
• Check operation of heating pressure relief valve. Pull
lever on top of valve upwards lifting the seat. This
will allow water to escape from system. Check water
is escaping from the system.
• Open combi models only domestic cold water inlet
valve. Turn on all hot water taps. Allow water to flow
until no air is present. Turn off taps. See page 4 -
Physical Data and section 2.7 Operational Features.
9.3 System Start Up
Follow all codes and regulations when filling the boiler.
Use drain taps to allow system to completely drain.
Thoroughly flush the heating system before boiler is
connected and again after first heating season.
