5 Boiler Installation
5.1 External Access Procedure
Fit the slotted straps “D” to the terminal “A” by placing over the
lugs and then bending the lugs to secure, see diagram 4.2.
From the inside fit the wall liner assembly “B” and “G” into the
hole.
Fit the top two fixing screws, allow them to stand proud to
accept the keyhole fixing slots on the boiler.
Mount the boiler and tighten the top screws and fit bottom
screw.
Locate and support the terminal, note, TOP is marked, see
diagram 4.2.
An alternative method of support is to attach a length of cord or
string, to the terminal through the small hole in the top centre of
the baffle, see diagram 4.2. Attach a suitable weight to the free
end of the cord etc. Pass the weight and cord through the hole
in the wall.
Working from the inside, attach the straps to the lugs on the
boiler, see diagram 4.4, bend the lugs and cut off excess strap
length.
Push the flue duct “F” into the terminal with the unflanged end
against the terminal. Ensure that the lower flange duct “F” fits
behind the combustion chamber rear panel. For walls less than
230mm thick cut to required length at the plain end of the duct.
Refit the two screws through the duct flange, but do not over
tighten.
Replace flue hood, securing angle, tie rods and wing nuts.
Refit the inner cover and secure with the screws previously
removed.
5.2 Internal Access Procedure
If required the terminal can be installed from inside the premises.
Fit the slotted straps “D” to the terminal “A” by placing over the
lugs and then bending the lugs to secure, see diagram 4.2.
Fit the top two fixing screws, allow them to stand proud to accept
the keyhole fixing slots on the boiler.
Attach a length of cord to the terminal through the small hole
provided in the top centre of the baffle.
Fit the liner assembly “B” and “G” into the hole through the wall.
Pass the terminal through the wall liner assembly, using the
cord with a suitable weight attached to hold the terminal in
position. NOTE, the terminal TOP is indicated and the flange on
the wall plate is located inside the wall liner assembly.
Hook the appliance onto the screws passing the string and
weight through the air duct in the back of the appliance.
Tighten the two upper screws and fit the bottom screw.
Attach the two slotted straps from the terminal to the two lugs on
the appliance, see diagram, bend lugs to secure. Cut off excess
strap length and remove cord.
Push the flue duct “F” into the terminal with the unflanged end
against the terminal. Ensure that the lower flange duct “F” fits
behind the combustion chamber rear panel. For walls less than
230mm thick cut to required length at the plain end of the duct.
Refit the two screws through the duct flange, but do not over
tighten.
Replace the flue hood, securing angle, tie rods and wing nuts.
Refit the inner cover and secure with the screws previously
removed.
