INSTALLATION INSTRUCTIONS
APPLIANCES INCORPORATING INTEGRAL LPG SUPPLY SYSTEMS
Cylinder retention
Lateral movement shall not exceed 25mm at the retention means. Any movement shall not
transmit strain to rigid tubing or pipe connections.
ENCLOSURES FOR INTEGRAL LPG SUPPLY SYSTEMS
Ventilation of cylinder enclosure
Ventilation openings shall:
(a) be provided at high and low levels; and
(b) have a total free area at high level of not less than 10,000mm
(c) have a total free area at low level of not less than 6,000mm
(d) consist of perforations with a total free area of not less than 25% of the sidewall area.
The bottom of the low level (set of) opening(s) shall be at the enclosure base with the upper edge
no more than 125mm above the base.
Accessibility of cylinder valve
The cylinder valve shall be readily accessible for manual operation. A door in the enclosure to
gain access to the cylinder valve is acceptable provided it is non-locking and can be opened
without the use of tools. An easily removable cover is also acceptable.
Installing cylinders
(a) Cylinders should be installed on a firm, level, non-combustible base, and not resting on soil.
The floor or base should be constructed so that water cannot accumulate within any
enclosure or recess.
(b) Cylinders should not be stacked on top of each other.
(c) Any cylinder that is liable to accidental dislodgment should be prevented from falling.
(d) Cylinders should not be installed below ground level unless there is sufficient ventilation to
prevent the accumulation of any leaking gas.
(e) A cylinder should be installed so that the pressure-relief valve is in contact with the vapour
space and, where practicable, any discharge from this valve is directed away from any
adjacent cylinders or combustible structures.
