5.7 DETERMINING THE FLUE LENGTH

IMPORTANT. The boiler must be installed in a vertical position in accordance to the installation instructions.

STANDARD FLUE KITS

Horizontal Flue Terminal RSF303 (600mm long) -contains:Flueturret,nontelescopicsinglepieceueincorporatingaterminal

and inner rubber wall seal.

Extension Kit RSF341 -contains:1metrelengthofuepipe(Functionallength950mm),1supportbracket.

When extension kits are used the ue duct must incline 1.5 degrees away from the appliance, to allow the condensate to drain back to

the boiler and out of the condensate drain. It is recommended that a support bracket is tted on every 1 metre of pipe work used and the

bracket is located as close to the collar as possible. The bracketing must ensure a 1.5 degree fall back to the appliance.

Only use water as a lubricant during assembly.

Once the ue is installed it is IMPORTANT that the white air duct protrudes from the aluminum spinning by at least 17mm.

The gap between the spinning and the white air duct MUST be sealed with sealant to create an adequate seal.
