7.3.3 Connection of flue gas discharge and choice
of material
Connecting the flue gas discharge:
Remove the cap from the flue gas discharge opening Ñ;
• Fit the flue gas discharge pipes seamlessly together .

• Seams and joints must be airtight and watertight or fit seamlessly .
• Horizontal parts must be oriented towards the boiler at a gra-
dient (min. 5 cm per metre).
• Connect the pipes stress-free.
• Flue gas discharge pipes longer than 2 m must be fixed separa-
tely and must not rest on the boiler .
Flue gas discharge:
Material:
Rigid single walled: stainless steel (316), aluminium or plastic (to
comply with building regulations).
Flexible: stainless steel (316).
Construction: all joints and seams should be gastight and water-
tight with the horizontal runs graded towards the boiler (min.
discharge 5 cm per meter) to allow condensate free drainage to
the boiler. Flue gas discharges longer than 2 meters must be sup-
ported independently and may not rest on the boiler .
The flue outlet should terminate with reduction cone and bird
guard only (chinamans hat or GLC type terminals etc. should not
be used).

7.3.4 Air supply connection and choice of material

Connecting air supply:
Remove air supply grille from the air supply opening Ð;
• Fit the air supply pipes seamlessly together .

• Seams and joints must be airtight and watertight or fit seamlessly .
• Horizontal parts must be oriented towards the discharge at a
gradient (min. 5 cm per metre).
• Connect the pipes stress-free.
Air supply:
Material:
Single walled, rigid or flexible: aluminium, stainless steel and plas-
tic (to comply with building regulations).
Air supply ducts longer than 2 meters must be supported inde-
pendently and may not rest on the boiler air inlet. Care must be
taken to ensure that if water is able to enter the duct it will run
away from the boiler air inlet connection or supply a suitable train
c/w water seal trap.
