15 

The water heater is to be installed at ground level on a concrete or brick plinth 
(fire proof base) and must stand vertically upright with the back of the water 
heater  against  an external wall or alternatively against a fireproof screen 
extending at least 500 mm above, below and either side the flue terminal. 
Failure to observe this precaution can cause problems in high wind areas. The 
water heater must be secured to the wall or screen using the brackets 
provided. A secondary flue is not required. 
 
Kits are available to enable the water heater to be installed partially recessed 
into an external wall. 
 
As a guide the following requirements extracted from the Australian Gas 
Installations Standard AS 5601, must be observed: 
 

• 

At least 300 mm between the top of 
the water heater and the eaves. 

• 

At least 500 mm between the water 
heater and the edge of any opening 
into the building, measured 
horizontally and vertically. 

• 

At least 500 mm between the water 
heater and a return wall or external 
corner, measured horizontally along 
the wall. 

• 

At least 500 

mm below any 

openable window. 

• 

At least 500 mm clear of any combustibles.
