B. LEVELING
In order for the condensate to properly flow out of the collection system, the area where you locate the heater must be level. Location
must also fully support the weight of the filled water heater.
C. CLEARANCES FOR SERVICE ACCESS
Figure 1 – Minimum Service Clearances
NOTE: If you do not provide the minimum clearances shown in Figure 1, it might not be possible to service the heater without removing
it from the space.
The space must be provided with combustion/ventilation air openings correctly sized for all other appliances located in the same space
as the heater. The heater cover must be securely fastened to prevent the heater from drawing air form the heater room. This is
particularly important if the heater is in a room with other appliances. Failure to comply with the above warnings could result in
substantial property damage, severe personal injury, or death.
D. RESIDENTIAL GARAGE INSTALLATION
PRECAUTIONS
If the heater is located in a residential garage, per ANSI Z223.1:
Mount the bottom of the heater a minimum of 18” above the floor of the garage, to ensure the burner and ignition devices are
well off the floor.
When raising the heater, fully support the entire bottom of the water heater.
Locate or protect the heater so it cannot be damaged by a moving vehicle.
E. EXHAUST VENT AND INTAKE PIPE
The heater is rated ANSI Z21.10.3 Category IV (pressurized vent, likely to form condensate in the vent) and requires a special vent
system designed for pressurized venting.
NOTE: The venting options described here (and further detailed in Venting, Part 5 in this manual) are the lone venting options
approved for this water heater. Failure to vent the water heater in accordance with the provided venting instructions will void
the warranty.
Failure to vent the water heater properly will result in serious personal injury or death.
