REAR OUTLET FLUE INSTALLATION

Extended flue Saunier Duval partnumber 85091. These are connected together by push fit type joints, clamps and seals. The horizontal flue is extended by using one or more of the 1000 mm extension pipes, Calculation of flue cutting lengths for extended flue •Using the correct number of extension kits as ta-ble 2 , measure dimensions a and e , see diagram13 or 14. Cut both the inner and outer pipe to thedimensions given in table 3.Important:

Cutting lengthOuter pipeInner pipe

All cutting lengths should be measuredfrom the push fit end of the extension pipe. Do not leave any burrs or sharp edges on the cut ends of the pipes. Installation of flue assembly-direct rear flue •Fit rubber sealing collar ( C ) into groove at theouter end of pipe ( Installation of flue assembly-side flue A H ), ) onto outer pipe.•Take hold of inner flue,twist clockwise and push gently onto fan outlet. •Pull rubber sleeve onto boiler spigot ensuring a good seal. see diagram 16. see diagram16. •Fit rubber sealing collar ( •Fit outer pipe ( •Fit internal plastic flange ( A ) into wall with groove to theoutside. •Pull pipe inwards to bring rubber sealing collar hard up against external wall, F C ) onto outer pipe. Pushalong the pipe until engaged against internal wall. •From inside, insert inner pipe ( ) into groove at theouter end of pipe ( B ) into outer pipeturning anti-clockwise to allow inner to fully enter outer pipe. •Fit rubber sleeve ( A H ), ) onto outer pipe.•Fit both 'O' rings see diagram 16. see diagram16. •Fit outer pipe ( •Fit internal plastic flange ( A ) into wall with groove to theoutside. •Pull pipe inwards to bring rubber sealing collar hard up against external wall, (F) into flue elbow F ) onto outer pipe. Pushalong the pipe until engaged against internal wall. •From inside, push inner pipe ( B ) into outer pipeturning anti-clockwise to allow inner to fully enter outer pipe. •Fit rubber sleeve ( (D) , one atthe inlet, one at the outlet. By necessity, they are a loose fit, apply a small amount of silicone grease to each 'O' ring when fitting.

Cutting length

Important : If the flue has been cut, ensure that thereare no burrs that could damage the 'O' ring.•Remove the backing from the self adhesive gas-ket
