HOT WATER SYSTEM
A.
If a boiler is fitted to this system it must be connected to a heating
system otherwise the warranty is void.
B.
There are two connections, both 1” BSP Female on the left hand side.
Follow general notes below.
C.
The D boiler is of mild steel construction for use on an open vented
indirect system.
D.
General Notes on Water System: -
1.
The cooker will produce hot water at differing rates depending
on how it is operated. Heating control is manual, no thermostat
is fitted.
2.
The system must be designed to cope with loads between the
maximum and minimum output. There must be sufficient gravity
load to absorb 2.6kW low pressure hot water output.
3.
A cylinder is essential for domestic hot water supply. Minimum
capacity is 135L.
4.
This unit is not approved for use with hydronic heating systems.
5.
Whichever system is chosen the layout must follow established
heating engineering practice. To avoid trapping air in the boiler
a 1” BSP connection must be used on the flow and return
tapping, and any reduction in pipe size thereafter being made on
a vertical rising pipe. The cooker must be level when fitted and
the flow pipe must rise from the boiler.
6.
The cylinder and pipe work should be lagged to avoid heat loss.
7.
The static head must not exceed 18 meters.
8.
A drain cock should be fitted to the lowest part of the circuit.
9.
The total water capacity of the boiler is 4 litres.
10.
A heat leak radiator should be fitted to absorb any excess heat
that may be produced.
11.
The system must be open vented.
