Pumped Heating & Gravity Hot
Water
(Fig. 17)
1. A 1in x 22mm threaded adaptor, two
compression nuts and olives and a brass injector
tee piece are provided in the kit for the return
connection.
NOTE:
The injector tee must be fitted to the
return of all systems with gravity domestic hot
water.
2. The 1in x 22mm threaded adaptor provided
must be fitted to the lower tapping marked
RETURN.
3. Fit the injector tee into the adaptor. The
injector tee may be oriented as shown to facilitate
connection to the gravity return pipework.
NOTE:
When connections are on the left,
ensure that the injector tee does not encroach
on the shaded area (Fig. 18). This area is
required for the firefront transformer assembly.
4. Connect the pumped return to the 22mm
compression fitting of the injector tee.
5. Take the gravity hot water return pipe to a level
beneath that of the injector tee and connect
upwards to the 28mm branch of the injector tee,
oriented as shown.
6. Connect the pumped flow to one of the
connections marked FLOW. Connect the gravity
flow to the remaining connection.
7. The gravity flow pipes must rise vertically as
close as possible to the appliance. Ensure the
pipework is routed such that it does not introduce
an airlock in the boiler.
8. Follow the instructions under system details as
regards the vent pipe and cold feed.
