Installation & Operation Manual

Vertical direct venting
Multiple vent/air terminations
1. When terminating multiple Armor X2 water heaters,
terminate each vent/air connection as described in this
manual (FIG. 5-3).
Terminate all vent pipes at the same height
and all air pipes at the same height to
avoid recirculation of flue products and
the possibility of severe personal injury,
death, or substantial property damage.
2. Place roof penetrations to obtain minimum clearance
of 12 inches (305 mm) between edge of air intake elbow
and adjacent vent pipe of another water heater for U.S.
installations (see FIG. 5-3). For Canadian installations,
provide clearances required by CSA B149.1 Installation
Code.
3. The air inlet of an Armor X2 water heater is part of a
direct vent connection. It is not classified as a forced air
intake with regard to spacing from adjacent water heater
vents.
