In some cases, it may be necessary to drill the fixing holes in the top cover to fit the
draught diverter to the water heater. By using the draught diverter as a template,
position carefully over the flueway and mark the hole positions to be drilled 4mm.
Fit the adaptor socket (2) and caulk into the draught diverter as shown in Fig. 1.
The location selected for installation of the heater must allow the provision of a
satisfactory flue, adequate air supply, drain facilities and must be well illuminated.
A purpose built boiler room or compartment is strongly recommended.
A manual valve for isolation of the boiler room should be installed in the gas supply;
it should be clearly identified and readily accessible for use at all times.
If a purpose built boiler room is not available, measures should be taken to protect the
heater from damage and prevent any extraneous matter from being stored on or around
the heater.
