to avoid the possibility of injury during the installation, servicing or cleaning of this

appliance, care should be taken when handling edges of sheet steel components.

key to symbols

= Ireland, GB = United Kingdom (Countries of destination)

PMS =

Maximum operating pressure of water

C13 C33 =

A room sealed appliance designed for

connection via ducts to a horizontal or vertical

terminal, which admits fresh air to the burner

and discharges the products of combustion

to the outside through orifices which, in this

case, are concentric. The fan is up stream of

the combustion chamber.

C63 =

A room sealed appliance intended to be

connected to a separately approved and

marketed system for the supply of combustion

air and discharge of combustion products.

The fan is up stream of the combustion

chamber.

B23 =

An appliance intended to be connected

to a flue which evacuates the products

of combustion to the outside of the room

containing the boiler. The combustion air is

drawn directly from the room. The fan is up

stream of the combustion chamber.

II2H3P =

An appliance designed for use on 2nd and 3rd

Family gases.
