BORE WATER SUPPLY
NOT RECOMMENDED FOR CONNECTION.
For further information contact SAXON Service. If the heater is connected to bore
supply against SAXON recommendation, warranty does not apply.
VENT PIPE
This Pipe Must Not Become Blocked or Obstructed.
It should be checked periodically to ensure it remains clear. To prevent accidental
discharge of hot water through the vent pipe whilst checking the valve, the vent
pipe may be extended downwardly. (See Connections Plumbing ‘vent Pipe’, Page 13)
ADJUSTING FLOW RATE
Failure to operate the water heater at the correct recommended flow rate could
result in unsatisfactory hot water delivery.
The best flow rate to heat water to the required temperature is 9 litres/minute
for the 140 litre model. For the 70 litre, 90 litre and 140 litre model, a flow rate in
excess of 9 litres/minute is not recommended. A flow rate up to 12 litres/minute
can be set for the 180, 280 and 400 litre units if desired.
To adjust the flow rate:
•
The cold water supply should be turned off at the stopcock which is situated
on the cold water inlet side of the unit.
•
Position an average household bucket of 9 litres under the laundry hot tap.
•
Turn the tap fully on and note how long it takes to fill the bucket.
•
A 9 litre bucket should fill in 1 minute for 9 litre/minute or 45 seconds for
12 litres/minute. Should the bucket not be filled or overflow in this time, the
flow rate can be adjusted by adjusting the water heater isolating the stopcock.
•
Repeat this procedure until the desired rate is achieved.
HOT WATER DELIVERY
As this water heater delivers water hotter than 50ºC, a temperature control device
is recommended to be fitted, at the water heater (See illustration, tempering valve,
Page 9) between the water heater and outlets in bathrooms and en suites.
REDUCING HEAT LOSSES
To reduce heat loss, it is recommended weatherproof insulation be applied to the
first 1.5 to 2m of the hot water line out of the water heater.
HEAT TRAP
A heat trap should be inserted in the hot water supply line. See diagram on Page 8.
Refer to National Plumbing Code AS/NZS 3500.4.
