Provide air openings to room:
The Armor X2 alone in boiler room
1. No air ventilation openings into the boiler room are
needed when clearances around the Armor X2 are at least
equal to the SERVICE clearances shown in FIG.’s 1-1
and 1-2. For spaces that do NOT supply this clearance,
provide two openings as shown in FIG. 1-1. Each
opening must provide one square inch free area per 1,000
Btu/hr of water heater input.
2. Combustion air openings are required when using the
Room Air Option on page 19 of this manual.
The Armor X2 in same space with other gas or oil-
fired appliances
1. Follow the National Fuel Gas Code (U.S.) or CSA B149.1
(Canada) to size/verify size of the combustion/ventilation
air openings into 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 Armor X2.
Do not install the water heater in an attic.
Failure to comply with the above warnings
could result in severe personal injury,
death, or substantial property damage.
2. Size openings only on the basis of the other appliances in
the space. No additional air opening free area is needed
for the Armor X2 because it takes its combustion air from
outside (direct vent installation).
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.
If flooding is possible, elevate the water heater sufficiently to
prevent water from reaching the water heater.
Flooring and foundation
Flooring
The Armor X2 is approved for installation on combustible
flooring, but must never be installed on carpeting.
Vent and air piping
The Armor X2 requires a special vent system, designed for
pressurized venting.
The water heater is to be used for either direct vent installation
or for installation using indoor combustion air. When room
air is considered, see Section 5, Vertical Direct Venting. Note
prevention of combustion air contamination below when
considering vent/air termination.
Vent and air must terminate near one another and may be
vented vertically through the roof or out a side wall, unless
otherwise specified. You may use any of the vent/air piping
methods covered in this manual. Do not attempt to install
the Armor X2 using any other means.
Be sure to locate the water heater such that the vent
and air piping can be routed through the building and
properly terminated. The vent/air piping lengths, routing
and termination method must all comply with the methods
and limits given in this manual.
Prevent combustion air contamination
Install air inlet piping for the Armor X2 as described in this
manual. Do not terminate vent/air in locations that can allow
contamination of combustion air. Refer to Table 1A, page
10 for products and areas which may cause contaminated
combustion air.
Ensure that the combustion air will not
contain any of the contaminants in Table
1A, page 10. Contaminated combustion
air will damage the water heater, resulting
in possible severe personal injury, death
or substantial property damage. Do not
pipe combustion air near a swimming
pool, for example. Also, avoid areas
subject to exhaust fumes from laundry
facilities. These areas will always contain
contaminants.
