3 General venting (continued)

Vent, air piping and termination:

The Armor water heater vent and air piping can be installed through the roof or through a sidewall. Follow the procedures in this manual for the method chosen. Refer to the information in this manual to determine acceptable vent and air piping length.

Optional room air

Optional room air is intended for NOTICE commercial applications. Combustion air piping to the outside is recommended

for residential applications.

Commercial applications utilizing the Armor water heater may be installed with a single pipe carrying the flue products to the outside while using combustion air from the equipment room. In order to use the room air venting option the following conditions and considerations must be followed.

The unit MUST be installed with the appropriate

 

room air kit (Table 3F).

The equipment room MUST be provided with

 

properly sized openings to assure adequate

 

combustion air. Refer to the instructions provided

Air contamination

Pool and laundry products and common household and hobby products often contain fluorine or chlorine compounds. When these chemicals pass through the water heater, they can form strong acids. The acid can eat through the water heater wall, causing serious damage and presenting a possible threat of flue gas spillage or appliance water leakage into the building.

Please read the information given in Table 1A, page 11, listing contaminants and areas likely to contain them. If contaminating chemicals will be present near the location of the water heater combustion air inlet, have your installer pipe the water heater combustion air and vent to another location, per this manual.

 

with the room air kit.

There will be a noticeable increase in the noise level

 

during normal operation from the inlet air opening.

Using the room air kit makes the unit vulnerable to

 

combustion air contamination from within the

 

building.

Please review Section 1, Prevent

 

Combustion Air Contamination, to ensure proper

 

installation.

 

Vent system and terminations must comply with the

 

standard venting instructions set forth in this

 

manual.

 

￿WARNING

￿WARNING

If the water heater combustion air inlet is located in a laundry room or pool facility, for example, these areas will always contain hazardous contaminants.

To prevent the potential of severe personal injury or death, check for areas and products listed in Table 1A, page 11 before installing the water heater or air inlet piping.

If contaminants are found, you MUST:

￿WARNING

When utilizing the single pipe method, provisions for combustion and ventilation air must be in accordance with Air for Combustion and Ventilation, of the latest edition of the National Fuel Gas Code, ANSI Z223.1, in Canada, the latest edition of CGA Standard B149 Installation Code for Gas Burning Appliances and Equipment, or applicable provisions of the local building codes.

Remove contaminants permanently.

—OR—

Relocate air inlet and vent terminations to other areas.
