INSTALLATION

INSTALLATION

2.4 

Place of installation

R

 

RTQ

 steel boilers must be installed in a dedicated boiler 

room, with adequately sized vents, in compliance with applica-

ble laws and standards.

If at all possible, the boiler should be installed on a raised base 

to prevent the burner fan sucking up dust.

 

9

When installing the boiler, allow sufficient space around it 

to access all safety and control devices and to permit easy 

maintenance.

 

9

If  the  specific  weight  of  the  gas  supply  to  the  burner  is 

greater than the specific weight of air, install all electrical 

parts at least 500 mm above floor level.

 

0

Do not install the boiler outdoors. It is not designed to work 

outdoors and is not fitted with the necessary automatic an-

ti-frost systems to do so.

2.5 

Installation in older systems and systems 
requiring modernisation

When installing these boilers in old systems or systems requiring 

modernisation, always perform the following checks:

 

− make sure that the stack is able to withstand the tempera-

ture of the combustion gases and that it has been designed 

and made in compliance with applicable standards. The 

stack must also be as straight as possible, sealed, insulated 

and not blocked or choked;

 

− make sure that the electrical system has been installed by a 

qualified electrician in compliance with applicable stand-

ards;

 

− make sure that the oil feed line and any oil storage tank are 

made and installed in compliance with applicable stand-

ards;

 

− make  sure  that  the  expansion  vessels  are  big  enough  to 

contain the volume generated by thermal expansion;

 

− make sure that flow rate, head and direction of flow of the 

pumps are suitable and correct;

 

− make sure that the circuit has been flushed out to remove 

all sludge and lime scale, and has been vented and seal 

tested.

 

− make sure that a suitable water treatment system is installed 

if the quality of the supply/recirculation water so demands.

2.6 

Water connections

R

 

RTQ

 boilers are designed and made for use in central heating installations, but can also be used for domestic hot water pro-

duction if connected to a suitable storage cylinder. Water fittings are as specified in the following table.

Allow for the dimensions of the control panel that needs to be installed on top of the boiler.
