7.0 wall
mounting
The Strata 1 boiler mounts to the wall
via a wall mounting bracket which interlocks
to a rail mounted upon the rear of the boiler.
The wall mounting bracket should be firmly
fixed to the wall using suitable fixings. The
wall mounting bracket positioning detail is
shown in fig 1. The boiler must be carefully
offered up to the wall so that the rail on the
rear of the boiler is just above the wall
mounting bracket and then the boiler should
be lowered to engage the bracket and rail.
Lifting is advised with 2 persons. Do NOT
lift the boiler by the internal parts of
the appliance.
Important Note
When viewed from the side, the
north/south axis of the boiler must be
vertical. The appliance must not be inclined
out from the top, if necessary adjust the
positioning of the boiler using the adjustable
wall bearing assemblies located at the
bottom rear left and right hand of the
appliance back panel.
8.0 gas
connection
The gas connection is located at the base
of the appliance rear centre, see fig 2.
The pipe size used to supply the
appliance must not be smaller than the gas
connection size on the appliance.
The connection to the appliance
must include a suitable method of
disconnection and a gas control cock must
be installed adjacent to the appliance for
isolation purposes.
The gas pipe used to supply the
appliance must not allow a pressure drop
of greater than 1mbar from the meter to
the appliance.
The nominal inlet working gas pressure
measured at the appliance should be
20.0 mbar for Nat Gas (G20) or 37 mbar for
LPG (G31). The installer should install a
pressure test point adjacent to the gas
inlet connection.
