ALWAYS CONNECT A MINIMUM FLUE EVACUATION AND INTAKE SECTION FOR BOTH
SYSTEMS OF AT LEAST 0.5 METRES (COAXIAL PIPE = 0.5m + 90° ELBOW; SPLIT 0.25 m
FLUE EVAC 0.25 m RESPECTIVE 90° ELBOWS)
FOLLOW APPLICABLE LEGISLATION AND REGULATIONS TO THE LETTER
INSTALL AIR INTAKE AND FLUE EVACUATION SYSTEMS CONFORMING TO THE
SPECIFICATIONS GIVEN ON THE TECHNICAL DATA PLATE AND OBSERVE ANY
LIMITATIONS ARISING FROM APPLICABLE LEGISLATION AND REGULATIONS TO THE
LETTER.
ONLY USE APPROVED COMPONENTS FOR AIR INTAKE AND COMBUSTION GAS
EVACUATION SYSTEMS WHICH ARE OF THE CORRECT DIMENSIONS AND PURPOSELY
DESIGNED AND MANUFACTURED FOR THE PURPOSE.
FOLLOW INSTALLATION INSTRUCTIONS TO THE LETTER.
INSULATE ANY FLUE SECTIONS WHICH WILL BE EXPOSED TO LOW TEMPERATURES.
TAKE MEASURES TO AVOID THE FORMATION OF EXCESSIVE CONDENSATION. ENSURE
THAT ANY CONDENSATION DOES NOT EVEN MINIMALLY AFFECT ANY INTERNAL
PART OF THE BOILER.
WHENEVER NECESSARY, PLACE APPROPRIATE CONDENSATE TRAPS ON THE FLUE
EVACUATION LINE:
Ensure the following before commissioning the boiler:
• THAT THE FLUE EVACUATION AND AIR INTAKE LINES ARE PERFECTLY SEALED
• THAT THEY ARE CORRECTLY POSITIONED AND FASTENED
• THAT THERE ARE NO MECHANICAL, THERMAL OR CHEMICAL STRESSES ON THE
LINES WHICH COULD EVEN MOMENTARILY COMPROMISE THEIR INTEGRITY.
INSTALL SYSTEMS TO ABSORB ANY THERMAL EXPANSION WHEN THE SECTIONS OF
FLUE DUCTING ARE LONGER THAN THE MINIMUM SPECIFIED LENGTHS.
