We  recommend  annual  inspection/service  of  your  gas  heating
system by a qualifi ed service agency. 

Failure to follow these instructions, misuse, or incorrect adjust-
ment of the burner could lead to equipment malfunction and re-
sult in asphyxiation, explosion or fire.

WARNING

Failure to observe the information given in this man-
ual, operating negligence, incorrect installation and
the carrying out of non authorised modifications will
result in the annulment by the manufacturer of the
guarantee that it supplies with the burner. 

WARNING

If you smell gas:

Do not touch any electrical items.

Open all windows.

Close all gas supply valves.

Contact your local gas authority immediately.

Do not store flammable or hazardous materials
in the vicinity of fuel burning appliances.

Improper  installation,  adjustment,  alteration,
service  or  maintenance  can  cause  property
damage, personal injury or death. 

Refer to this manual for instructional or addition-
al information. 

Consult a certified installer, service representa-
