3.27.1 Installation procedure

1. The Horizontal or Vertical flue kit that has been
delivered includes the components as listed below and
on page 21. The concentric flue pipe system includes
both the flue exhaust (inside pipe) and combustion air
(outside pipe). The flue pipe may be cut on the unflared
end (end without gasket) as required for installation.
2. Determine if additional flue components are required for
installation. Refer to the flue component information on
pages 21 and 55 for available optional flue components.
3. Ensure that the flue terminal location complies with
requirements described within this manual and the
Local Codes of Practice.
4. Measure the vertical and horizontal distance from the
water heater flue connection to determine the number
of components required.
