Direct Flueing - Mushroom Flue Kits - Rinnai Arriva Flue Installation Manual

Direct flueing - mushroom flue kits

For installations where the unit is mounted directly on the inside of an external wall.
This installation requires a 2° fall from the heater connection to the wall terminal to
drain condensate and wind blown rain—the Arriva Direct A and B flue kits have an
inbuilt 2° fall.

Before starting, create the wall penetration. The minimum diameter required is 80 mm to non-
combustible surfaces such as brick, and 100 mm to combustible surfaces such as plaster.
1. Disassemble manifold
The flue consists of three parts;
sleeve, inside connections and
tube, and outside terminal.
Disassemble by pulling hard on
