Condensate, gas and water connections
4.5.1
Condensate connection
The condensate pump fills up and periodically discharges through the
flexible condensate pipe [8] between 200mm to 4500mm from floor
level. After this point the condensate flows, due to gravity, down the
21.5mm plastic pipe to the outlet.
▶ Fit the bayonet connector on the end of the condensate waste pipe to
the condensate pump. Push down and rotate clockwise until the
connector is locked.
▶ Route and secure the flexible condensate waste pipe [8] ensuring
that the condensate waste pipe is clipped securely either side of any
change of direction to prevent kinking or restriction.
▶ Cut off any excess pipe [8].
▶ Fit the condensate waste pipe [8] to adaptor [11] and secure with
clip [10].
▶ Connect adaptor [11] to 21.5mm plastic pipe and terminate
appropriately as described in section 3.4.
Fig. 23 Condensate connection
(See Pre-Installation section for condensate pipe work running from the
adaptor [11] to the discharge outlet).
Never terminate or discharge into any open source, including; sink,
basin, bath, shower, bidet, toilet etc.
4.5.2
Gas and water connections
▶ Ensure that the transit bung [12] has been removed from the gas and
water connections [A, B, C, D & E] on the boiler.
▶ Ensure the area is clear of debris and manoeuvre the boiler rear
wheels onto the outer rails of the mounting frame [6].
▶ Take care when moving the boiler to position the front wheels onto
the rails and align the gas/water connections and the flue.
▶ Secure boiler to mounting frame [6] with screw [13]
▶ Place the 4 larger valve sealing washers (shown shaded) onto valves
[A, B, D & E].
▶ Place the bonded washer [C] on to the gas valve.
▶ Ensure all pipe work is clean.
▶ Tighten up the flat sealing connections to secure:
[A] - CH flow (22mm).
[B] - DHW flow (22mm).
[C] - Gas inlet (22mm) (bonded washer).
[D] - Mains water inlet (22mm).
[E] - CH return (22mm).

Pressure relief valve outlet
Fitting the pressure relief valve drain pipe (
figure 24):
▶ Connect a length of 15mm copper pipe [14] to the PRV drain pipe
[15].
The PRV drain pipe [15] should be at least 15mm diameter and run
down away from any electrical or other hazard.
Auto air vent:
▶ Release the auto air vent cap [16].
▶ Any external condensate pipe work should be
protected with weather resistant insulation to help
prevent freezing.
▶ The flexible pipe supplied can only be used inside the
property.
CAUTION:
ISOLATE THE MAINS GAS AND WATER
SUPPLY BEFORE STARTING ANY WORK AND OBSERVE
ALL RELEVANT SAFETY PRECAUTIONS.
Surplus water may be present due to factory testing.

NOTICE:
The pressure relief valve is a safety device for
the boiler and if activated may discharge boiling water or
steam through the PRV drain pipe.
