COMMISSIONING 

50 

IN-SERIES BOOSTER 

Refer  to  the  Owner’s  Guide  and  Installation  Instructions  supplied  with  the  in-series  water  heater  for  the 
commissioning procedure of the in-series water heater. 
 
If a continuous flow gas water heater has been installed as an in-series gas booster to the solar water heater, 
then to complete the installation, it is necessary to check the gas supply pressure at the inlet to the in-series 
gas booster, and also the minimum test point pressure and the maximum test point pressure of the in-series 
gas booster. Refer to 

“Gas Inlet Pressure” and to “Burner Gas Pressure” in the Owner’s Guide and Installation 

Instructions supplied with the in-series gas booster. 
 

PRESET OUTLET TEMPERATURE 
Note:

 AS 3498 requires that a water heater provides the means to inhibit the growth of Legionella bacteria in 

potable  water.  If  this  water  heater  is  installed  with  an  in-series  continuous  flow  gas  booster,  then  this 
requirement of AS 3498 can be satisfied provided the booster is energised, its preset outlet temperature setting 
is 70°C or higher and a remote temperature controller or an EZiSET kit is not used. 
 
If  this  water  heater  is  installed  with  an  in-series  storage  booster,  then  this  requirement  of  AS  3498  can  be 
satisfied provided the storage booster is energised and its thermostat setting is 60°C or higher. 
 
It will be necessary to check and if required to adjust the preset outlet temperature setting of the continuous 
flow water heater or the thermostat setting of a storage water heater when it is installed as an in-series booster 
to a solar water heater or if it is an existing water heater and a solar water heater is then installed. 
 
Refer to the Owner’s Guide and Installation Instructions supplied with the in-series continuous flow gas booster 
for the procedure to check and adjust the preset outlet temperature if required. 
 
Refer to the Owner’s Guide and Installation Instructions supplied  with the in-series storage booster for the 
procedure to check and adjust the thermostat setting if required. 
 

Note:

  Consideration  must be  given  to the  delivery  temperature  to  any  ablution  and  public  areas  such  as  a 

bathroom, ensuite or public amenities. Refer to 

“Hot Water Delivery”

 on page 26 and to the schematics of 

“Two 

Temperature Zones Using A Temperature Li

miting Device”

 on page 27. 

 

BLEEDING THE SOLAR COLLECTOR(S) 

Upon  completion  of  the  installation,  if  the  service  3-
way  valve  was  not  opened  during  the  tank  filling 
procedure,  then  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  pair  of  pliers  or  other  appropriate  tool, 
open the service 3-way valve fitted at the solar hot 
water  inlet  (from  collector)  of  the  solar  storage 
tank (see diagram). 

 Warning:

 Stand well aside of the service valve 

drain  pipe  discharge  point  and  exercise  care  to 
avoid any splashing of water, as water or in some 
circumstances  steam  discharged  from  the  solar 
collector(s) may be of a very high temperature. 

 

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

Note:

 Allow  water to flow from the drain line for  a few minutes before closing the service valve. Water 

already in the solar hot pipe will drain out prior to air in the top of the collector circuit being purged by the 
mains pressure water rising in the solar cold pipe. 

 

Close the service valve when water runs freely under mains pressure from the drain line.
