4.9 Water & Gas connections
Replace fan access door, heat shield and control box.
Note: When replacing the fan access door make sure the lip at
the top of door fits into and behind the slotted bracket located at
the top of the boiler.
As there are two casing height options, the control box height
and the heat shield may have to be adjusted to suit your
requirements.
Complete the water connections to the boiler.
Fill, vent and flush the system.
Check for any water leaks and put right.
Make the gas connection to the service cock, at the lower left
hand side of the boiler, see diagram 1.1.
The whole of the gas installation, including the meter, should be
inspected, tested for soundness and purged in accordance with
the current issue of BS6891.
4.10 Condensate Drain Connection
(If Applicable)
With reference to Section 3, should your flue be greater than the
"Dry" flue length stated, then a condensation drain should be
fitted.
The condensate drain connection is on the chimney flue adapter,
see diagram 4.15. A 22mm plastic overflow pipe should be used
to fit on to the drain connection and discharge to a drain. The
drain pipe should have a fall of at least 2.5
°
away from the boiler
and should incorporate a 'U' trap.
Condensate should, if possible be discharged into the household
internal drainage system. If this is not practicable, discharge
can be allowed into the external household drains or by a
purpose designed soak away.
It is recommended that any external condensate drain is insulated
and also preferably of 32mm diameter, to prevent freezing in
adverse weather conditions.
4.11 Top Casing
Refer to diagram 4.16.
Fit two plastic pegs, one on each side, in the holes on the top
casing. The plastic pegs are a tight fit and are best pushed home
with a flat faced tool.
Secure front of top casing with the two screws provided.
