and controls met safe lighting and other
performance under tests specified in ANSI
Z21.10.3 – latest edition.
Before locating the water heater, check:
1.
Check for nearby connection to:
• Water piping
• Venting connections
• Gas supply piping
• Electrical power
2. Locate the appliance so that if water connections should
leak, water damage will not occur. When such locations
cannot be avoided, it is recommended that a suitable
drain pan, adequately drained, be installed under the
appliance. The pan must not restrict combustion air
flow. Under no circumstances is the manufacturer to be
held responsible for water damage in connection with
this appliance, or any of its components.
3. Check area around the water heater. Remove any
combustible materials, gasoline and other flammable
liquids.
Failure to keep water heater area clear and
WARNING
free of combustible materials, gasoline, and
other flammable liquids and vapors can
result in severe personal injury, death, or
substantial property damage.
4. The Armor X2 water heater must be installed so that gas
control system components are protected from dripping or
spraying water or rain during operation or service.
5. If a new water heater will replace an existing water heater,
check for and correct system problems, such as:
• System leaks causing oxygen corrosion or heat exchanger
cracks from hard water deposits.
6.
Check around the water heater for any potential air
contaminants that could risk corrosion to the water heater
or the water heater combustion air supply (see Table 1A
on page 10). Prevent combustion air contamination.
Remove any of these contaminants from the water heater
area.

Closet and alcove installations
A closet is any room the water heater is installed in which
is less than 778 cubic feet for AW1000 models, 847 cubic
feet for AW1300 models, and 914 cubic feet for AW1500
models.
An alcove is any room which meets the criteria for a
closet with the exception that it does not have a door.
Example: Room dimensions = 9 feet long, 9 feet wide,
and 9 foot ceiling = 9 x 9 x 9 = 729 cubic feet. This would
be considered a closet for a Armor X2 water heater.
For closet and alcove installations as
WARNING
shown in FIG.'s 1-1 and 1-2, CPVC,
polypropylene, and stainless steel
vent material must be used inside the
structure. The ventilating air openings
shown in FIG.'s 1-1 and 1-2 are
required for this arrangement. Failure
to follow this warning could result in
fire, personal injury, or death.
Provide clearances:
Clearances from combustible materials
1. Hot water pipes—at least 1/4" from combustible
materials.
2. Vent pipe – at least 1" from combustible materials.
3. See FIG.'s 1-1 and 1-2 on page 8 for other clearance
minimums.
Clearances for service access
1.
See FIG.'s 1-1 and 1-2 on page 8 for recommended
