6Connecting the boiler

The boiler has the following connection pipes;

-The central heating circuit pipes.

These must connected to the plumbing kit by means of adapter fittings.

See further chapter 6.1;

-The gas supply pipe.

It is provided with a 3/4" male thread into which the tail piece of the gas valve can be screwed. See further chapter 6.4;

-Cold and hot water pipes for domestic hot water (DHW).

These consist of 3/4" (15 mm) copper pipe and can be connected to the installation by means of 1/2" M-NPT adapter fittings. See further chapter 6.5;

-The condensation drain pipe.

It consists of an oval 1" (22 mm) plastic pipe. The drain pipe can be connected to this by means of an open connection. If the open connection is fitted in a different location, then the pipe can be lengthened by means of a 1 1/4" (32 mm) PVC sleeve. See further chapter 6.6;

-The vent system and air supply system.

It consists of a concentric connection 3"/5" (80/125 mm). The boiler can be converted to a twin pipe connection that will accept 80mm flue and intake air or with the use of the included adapters 3” PVC/CPVC flue and intake. See further chapter 6.7.

i NOTICE

The pipe to be connected to the boiler must be cleaned before connecting in

order to prevent dirt from entering and damaging the boiler.

Connect the central heating system according to its instructions.

 

The boiler pipes can be connected to the installation by means of compression fittings.

 

Reducers should be used for connecting to thick-walled pipe (welded or threaded).

NOTICE

When removing the plastic sealing caps from the pipes, dirty testing water

may drain from the boiler.

NOTICE

A Plumbing Kit must be fitted to the boiler.

 

 

The boiler, when used in connection with a refrigeration system, must

NOTICE

be installed so the chilled medium is piped in parallel with the boiler with

appropriate valves to prevent the chilled medium from entering the boiler.

 

The boiler piping system of a hot water boiler connected to heating coils

NOTICE

located in air handling units where they may be exposed to refrigerated air

circulation must be equipped with flow control valves or other automatic

 

means to prevent gravity circulation of the boiler water during the cooling

 

cycle.
