Page 25

IMPORTANT: Insulate all external condensate pipe work or run in 32mm pipe work to prevent freezing.

PIPEWORK CONNECTIONS

H - Flue manifold condensate outlet

J- Condensate outlet (21.5mmØ) - supplied K - Condensate pipe - not supplied

L- Condensate trap with clamp - supplied M - Pressure relief (15mmØ)

CONDENSATE CONNECTION:

 

The condensate trap (L) must be installed

 

onto the bracket supplied.

 

Measure condensate pipe (J) mark and cut

 

square to length required.

 

Fit sealing washer inside condensate pipe

 

nut and connect to the flue manifold outlet (H).

 

Connect 21.5mm polypropylene pipe (K) (not

 

supplied) to the condensate pipe (J)

 

and condensate trap (L) before terminating

 

to waste.

 

Secure the condensate trap (L) with clamp

 

supplied.

 

Ensure that the condensate pipe runs away

 

from the boiler at a constant fall of 50mm

 

(min.) for every metre.

 

Carefully pour 500ml of water into the

 

condensate collection (R) to fill condensate trap.

 

Check the water is running away and the

 

condensate pipework joints are water tight.

 

Check the flue manifold seal is undamaged

INSTALLATION

correctly filled to prevent the possibility of

and seated correctly.

 

Refit flue manifold access cover (Q) and

 

secure with screws (P).

 

IMPORTANT: The condensate trap must be

 

potentially harmful flue products escaping

 

via the condensate pipework.

 

 

 

PRESSURE RELIEF CONNECTION:

 

Connect the pressure relief pipe (M) to a

 

copper discharge pipe (15mmØ min.) and

 

terminate externally to the appliance casing.

 

Blank all unused casing holes with the bungs

 

or cover plates and seals supplied. The

 

drain/fire valve capillary hole covers should

 

be rotated so that the unused capillary slot is

 

covered by the cover plate and seal.

 

Refit rear panel.

 

Seal all joints where pipes pass through the

 

casing, with suitable waterproof sealant.
