GAS INLET PRESSURE 
IMPORTANT – CHECK the gas supply pressure at the inlet to the water heater 
with the water heater and all other gas burning appliances in the premises 
operating (burners alight). The minimum gas supply pressure is: 
 
Natural Gas 

1.13 kPa 

Propane 

2.75 kPa 

Butane 

2.75 kPa 

 
If this minimum cannot be achieved, it may indicate the meter or the gas line to 
the water heater is undersized. It is important to ensure that an adequate gas 
supply pressure is available to the water heater when other gas burning 
appliances, on the same gas supply, are operating. 
 
BLEEDING THE SOLAR COLLECTORS 
Upon completion of the installation, it is necessary to purge the air from the 
collector circuit. 
 
To purge air from the collector circuit: 

• 

Ensure the water heater is full of water and all of the hot taps are turned off. 

• 

Using a flat blade screwdriver, 
open the bleed valve fitted 
adjacent to the solar hot water 
(from collector) inlet of the 
solar storage tank (see 
diagram). 

 

 

• 

The mains pressure will force 
water to flow from the tank 
and through the pipe work, 
forcing air from the collector 
circuit through the bleed 
valve. This is evidenced by 
spurting of water from the 
drain line connected to the 
bleed valve. 

 Warning: Exercise care to 

avoid any splashing of water, 
as water discharged from the 
solar collectors may be of a 
very high temperature. 

• 

Close the bleed valve when water runs freely from the drain line.
