Installation & Operation Manual

1 Determine water heater location

Provide air openings to room:

Armor water heater alone in equipment room

1.No air ventilation openings into the equipment room are needed when clearances around the Armor water heater 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.

Armor water heater 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.

Residential garage installation

Precautions

Take the following precautions when installing the appliance in a residential garage. If the appliance is located in a residential garage, it should be installed in compliance with the latest edition of the National Fuel Gas Code, ANSI Z223.1 and/or CAN/CGA-B149 Installation Code.

•Appliances located in residential garages and in adjacent spaces that open to the garage and are not part of the living space of a dwelling shall be installed so that all burners and burner ignition devices are located not less than 18 inches (46 cm) above the floor.

•The appliance shall be located or protected so that it is not subject to physical damage by a moving vehicle.

Vent and air piping

￿WARNING

The space must be provided with combustion/ ventilation air openings correctly sized for all other appliances located in the same space as the Armor water heater.

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.

The Armor water heater 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 the General Venting Section. Note prevention of combustion air contamination below when considering vent/ air termination.

Vent and air must terminate near one another and may be

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 water heater because it takes its combustion air from outside (direct vent installation).

Flooring and foundation

Flooring

The Armor water heater is approved for installation on combustible flooring, but must never be installed on carpeting.

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 water heater 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.

￿WARNING 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.

Prevent combustion air contamination

Install air inlet piping for the Armor water heater as described in this manual. Do not terminate vent/air in locations that can allow contamination of combustion air. Refer to Table 1A, page 11 for products and areas which may cause contaminated combustion air.

￿WARNING

You must pipe combustion air to the water heater air intake. Ensure that the combustion air will not contain any of the contaminants in Table 1A, page 11. 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.
