FIGURE 9-1 Condensate Drain Assembly
Model 205 shown (location similar in all sizes)
Pour
approximately
1 cup of water
into flue way of
boiler.
9 - START UP PROCEDURE
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
draining properly.
Note
Condensate trap must be manually filled with water
at initial start up.
Condensate Drain
•
Boiler is fitted with automatic air vent positioned on pump
and is fitted with adjustable sealing cap. See Figure 9-1.
•
Open central heating flow and return valves.
•
Open system fill valve 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 if it is not
circulating. Unscrew and remove cap from center of pump.
Use a screwdrive, 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 Physical Data page 4 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.
