Multi Pass Oil Boilers
1
Fit the thermostat pocket (supplied with the burner)
into one of the tappings on the top of the boiler - If
both heating flow and return connections are on
one side, position the pocket on that side. Use a
small amount of jointing compound on the threads.
Note: Boiler House models - Use the thermostat
pocket supplied with the boiler/overheat thermostat
assembly.
Plug the other connection using the ½" BSP plug
supplied with the boiler.
2
Fit any elbows, bushes etc. to the water
connections before placing the boiler in position if
access will be restricted.
Note: If the boiler is to be positioned against a side wall,
the water connections may be taken from one side only,
(see paragraph 1 for thermostat pocket position).
3
Ensure that all the plastic caps have been removed
from the boiler connections.
4
Fit the drain cock (supplied), in the bottom right hand
connection on the front of the boiler (½" BSP).
5
Plug all connections not to be used and carefully
manoeuvre the boiler into position.
6
Balanced flue models - Do not make any water
connections at this stage.
7
Conventional flue models only - Complete the
water connections and fill the water system. Check
for leaks, rectifying where necessary.
