hob, then 50 mm clearance is required from the range. Any combustible surface
higher than that would need to have at least 250 mm clearance, or be protected.
These clearances do not apply where an adjacent surface is of a non-combustible
material or is combustible but is protected with fire resistant material in accordance
with Appendix C. The fire resistant material may be covered by ceramic tiles or
stainless steel to meet local Health Authority requirements.
Care should be taken where a combustible surface is covered by a non-combustible
material. For example, covering a combustible surface with stainless steel will not
prevent heat transfer, and in some circumstances a hazardous situation could arise.
Refer to Clause 5.3.7 for requirements regarding appliances above a source of
cooking vapour, steam or grease.

5.12.4.6 Commercial catering equipment on a combustible surface
Where commercial catering equipment is installed on a combustible surface the
surface shall be protected by fire resistant material. The protection is to extend at
least 50 mm beyond the perimeter of the appliance and is to be made impervious to
cooking fats.

Licensed to LUU MINH LUAN on 26 Feb 2002. Single user licence only. Storage, distribution or use on network prohibited.

NOTE: This requirement does not apply where the lowest burner on the appliance is over
200 mm above the mounting surface, and a heat shield below the burner is incorporated
in the design of the appliance.

5.12.7.2 Type of supporting base
A pool heater, unless stated otherwise in the manufacturer’s installation
instructions, shall be installed on a stable non-combustible base.

5.12.7.3 Requirement for pool heater where flow and return water pipes
are of plastic
Where the water flow and return pipes are of plastic, these pipes shall be connected
to the heater with a minimum of 1 m of unlagged metallic pipe unless stated
otherwise in the pool heater manufacturer’s instructions.
NOTE: This requirement prevents the plastic pipe being affected by residual heat when
the pool heater is shut-down.

5.12.7.4 Non-return valve required
A non-return valve shall be fitted in the water return line between the filter and the
pool heater.

5.12.7.5 Restriction on fitting of a valve in water flow line
A valve shall not be fitted in the water flow line between the heater and the pool,
unless there is an arrangement to vent the system when the valve is closed. Where
such venting is provided by a pressure relief valve, that valve shall comply with
AS 1357.1 and be fitted with a drain which is installed in accordance with
AS 3500.4.1.

5.12.7.6 Requirements where a pool heater is used for a spa or
therapeutic pool
Where a pool heater is used for a spa or therapeutic pool application, the heater or
the installation shall have a manual reset temperature limit device which prevents
the water temperature in the pool exceeding 45°C. The manual reset temperature
limit device is to act independently of the heater control thermostat and shall either
shut off the gas supply to the burner by a separate gas valve, or switch off the
circulating pump.
NOTE: Consult with the appliance manufacturer to determine which method of connecting
the manual reset temperature limit device is most appropriate.
