Rheem 27 Owner's Manual And Installation Instructions page 67

Carefully remove the template inserted as the middle pages of this installation instructions booklet.
5.
Cut along the middle of the bold circle marked "Cut Line".
6. Align the top of the circular template with the mark on the wall.
It may be convenient to tape the template to the wall.
Mark the pilot hole through the centre of the template and scribe around the template onto the wall.
7.
The scribed circle should be 150 mm in diameter.
Remove but DO NOT DISCARD the template.
Drill a pilot hole using a 6.5 mm diameter or smaller drill bit.
8.
The drill bit must be long enough to penetrate completely through the outer skin of the external wall.
Note: Ensure the drill remains level and straight during this step.
Align the centre of the template with the pilot hole on the outside wall surface and scribe around the
9.
template onto the wall.
The scribed circle should be 150 mm in diameter.
Remove the template.
Drill or cut the flue termination hole through the wall using a cutting tool suitable for the wall construction.
10.
Note: The Trim Ring (PN 295125) will cover a 150mm diameter hole.
Connect a Condensate Drain Section (PN 295120) to the water heater flue adaptor prior to the 90° Bend
11.
if there is a long vertical rise directly from the water heater or if the flue is to have a change of direction
from horizontal to vertical.
Note: If there is insufficient height above the water
heater for the Condensate Drain Section and a
90° Bend, then the 90° Bend is to be connected to the
Water Heater Flue Adapter and the Condensate Drain
Section installed in the horizontal position immediately
after the 90° Bend.
Refer to "Draining the Condensate"
Install a condensate drain line and Condensate Trap.
Refer to "Condensate Drain Line and Condensate Trap"
12. Starting from the 90° Bend or Condensate Drain Section and working towards the terminal location
connect all of the other flue system components.
Ensure each flue component is fully engaged and
the rubber seal on the inner duct is well seated at
each joint.
Secure each flue component using the sheet metal
13.
screws provided.
Support horizontal sections at a distance no greater than
14.
2 m using a Wall Bracket (PN 295129).
15. A horizontal run of flue connecting directly to a Horizontal Flue Terminal must have a downward gradient
to the flue terminal.
Use Male to Male and Female to Female Adapters to reverse the direction of flue insertion where
two or more sections of flue are used in a horizontal flue run and the flue drains toward the flue
terminal. Refer to the
This provides for proper draining of condensate without pooling at the flue component joins.
