Table 1B Corrosive Contaminants and Sources
Provide clearances:
Clearances from combustible materials
1. Hot water pipes—at least 1/4" (6mm) from combustible
materials.
2. Vent pipes—minimum of 14" (356mm) from the rear and
0" on the right side from combustible materials.
Clearances for service access
1. If you do not provide the minimum clearances, it may
not be possible to service the water heater without
removing it from the space.
Recommended service clearances:
Front
-
30" (762mm)
Top
-
24" (610mm)
Left side -
24" (610mm)
Rear
-
24" (610mm)
Under no circumstances is the manufacturer to be held
responsible for water damage in connection with this appliance,
or any of its components. If flooding is possible, elevate the
water heater sufficiently to prevent water from reaching the
water heater.
Prevent combustion air contamination
Do not install in locations that can allow contamination of
combustion air. Refer to Table 1B for products and areas
which may cause contaminated combustion air.
Outdoor vent / air intake location
The flue products discharged from the flue
outlet on the outdoor vent may be very
hot. Avoid touching or other direct contact
with the flue gases or the vent termination
assembly. These components are hot and
direct contact can result in burns.
WARNING
To prevent recirculation of the flue products into the combustion
air inlet, follow all instructions in this section.
Flue gas condensate can condense on exterior walls or on the
vent. Some discoloration to exterior building or unit surfaces
can be expected. Adjacent brick or masonry surfaces should be
protected with a rust resistant sheet metal plate.
Maintain a minimum of 24" (610mm) clearance to the side of
the air inlet.
Locate the outdoor vent termination at least 48" (1.22m) below
and 48" (1.22m) horizontally from any window, door, walkway
or gravity air intake.
Locate outdoor unit at least 10 feet (3.05m) away from any
forced air inlet.
Multiple outdoor unit installations require 24" (.61m) clearance
between each vent termination.
Clearances around outdoor installations can change with time.
Do not allow the growth of trees, shrubs or other plants to
obstruct the proper operation of the outdoor vent system.
Do not install the water heater on carpeting
even if foundation is used. Fire can result,
causing severe personal injury, death, or
substantial property damage.
Flooring and foundation
Flooring
The outdoor Armor water heater is approved for installation on
combustible flooring.

Installation & Operation Manual
3. Check area around the water heater. Remove any
combustible materials, gasoline and other flammable
liquids.
Failure to keep the water heater area clear
and free of combustible materials, gasoline
and other flammable liquids and vapors can
result in severe personal injury, death or
substantial property damage.
WARNING
4. If a new water heater will replace an existing water heater,
check for and correct system leaks causing oxygen corrosion
or heat exchanger cracks from hard water deposits.
