Vertical Flue Installation; To Install A Vertical Flue And Termination - Rheem 27 Owner's Manual And Installation Instructions

VERTICAL FLUE INSTALLATION

Suitable flashing (not supplied) is required to waterproof the roof penetration.
Notes:
•
Ensure each flue component is fully engaged and the rubber seal on the inner duct is well seated at
each joint.
•
Each flue component is supplied with screws to connect to the adjacent flue component. The screws are
located in a bag taped to the outside of the flue component.
•
Refer to diagrams:
"Typical Installation – Vertical Flue"
"Typical Installation – Vertical Terminal with Vertical and Horizontal Sections"

To install a vertical flue and termination:

Determine the location where the flue will penetrate through the roof.
1.
Note: Ensure there are no rafters, purlins, pipes or electrical cables located in the roof where the flue is
to penetrate.
Drill or cut the flue termination holes through the roof and ceiling of a suitable size to allow the
2.
installation of the flue, using a cutting tool suitable for the roof construction.
Connect the Water Heater Flue Adapter (PN 295121) to the
3.
water heater flue outlet.
Fit the end of the adapter down over the water heater
flue outlet as far as it will go.
Ensure there is a minimum 35 mm and maximum 42 mm
overlap, the rubber seal on the inner flue is well seated
and the adapter is fully engaged on the water heater flue
outlet.
Tighten the ring clamp provided with a screw driver.
Connect the Condensate Drain Section (PN 295120) to the
4.
Water Heater Flue Adapter.
Note: If the flue is required to be offset and there is
insufficient height above the water heater for both the
Condensate Drain Section and a bend, then the bend is to
be connected to the Water Heater Flue Adapter. The
Condensate Drain Section is to be installed immediately after
the bend or alternatively immediately after a second bend in
a vertical orientation if two bends are connected together.
The Condensate Drain Section must be installed as close as practicable to the water heater and can be
installed in either a vertical or horizontal orientation. If horizontal ensure the drain is pointing downwards.
Refer to "Draining the Condensate"
Fit a condensate drain line and Condensate Trap.
Refer to "Condensate Drain Line and Condensate Trap"
5. Continuing from the Water Heater Flue Adapter 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.
