5.5 Installation of the supply pipes
▶ Determine the internal pipe diameter for the gas supply in accordance
with AS/NZS 5601.
▶ All pipe connections in the heating system must be suitable for a
pressure of 3 bar.
▶ Install regulator
1)
(only for NG appliance) and convert connection
1)
.
▶ For filling and draining the system, fit drain & fill valves at the lowest
point of the system.
▶ Use corrosion-resistant materials to produce the drain for the safety
valve.
Such materials include: vitrified clay pipes, hard PVC pipes, PVC
pipes, PE-HD pipes, PP pipes, ABS/ASA pipes, cast-iron pipes with
enamel lining or coating, steel pipes with plastic coating, stainless
steel pipes, borosilicate glass pipes.
▶ The PRV is a safety device for the boiler and if activated may discharge
boiling water steam through the relief valve drain line.
5.6 Checking the connections
Water connections
▶ Open the heating flow and return valves and fill the heating system.
▶ Check sealing points for tightness (testing pressure: max. 2.5 bar at
the pressure gauge).
Gas Connection:
• Fit a union to the water heater gas inlet for easy connection and
removal. The thread diameter is 20 mm.THIS DOES NOT INDICATE
THE SIZE OF THE GAS SUPPLY.
• Fit an AGA / NZGA approved isolating gas valve in the supply line
adjacent to the water heater gas connection..
• Ensure that the supply pipe and the gas pressure regulator (LPG or
Natural Gas) has sufficient flow capacity for this and other appliances
connected to the fitting line.
• For LPG appliances ensure that gas cylinders are of sufficient size.
• Before connecting the appliance to the gas service, purge any debris
or air from the gas service.
• Check all joints for leaks with an approved leak tester after
connection.
Refer to AS/NZS 5601 Installation Code for pipe sizing and
details.Ensure that the gas pipe size is correct. If undersized the
appliance will not operate correctly .For Natural Gas installations where
the inlet pressure exceeds 1.5kPa an appliance regulator is
supplied.SERVICE CALLS ARE CHARGEABLE FOR UNITS WITH
INCORRECT PIPE SIZES OR BLOCKED GAS OR WATER FILTERS.
Testing Gas Supply Pipe
▶ Close the gas valve to protect the gas train from pressure damage.
▶ Check sealing points for leaks (testing pressure: max. 15Kpa).
▶ Release the pressure on the gas supply pipe.
5.7 Connecting the flue accessories
▶ Ensure that the gasket is fitted inside the flue outlet.
▶ Push on the flue gas elbow and secure with the screws supplied.
