Prevent combustion air contamination

WARNING

If the appliance combustion air inlet is located in any area likely to cause contamination, or if products which would contaminate the air cannot be removed, you must have the combustion air and vent re-piped and terminated to another location. Contaminated combustion air will damage the appliance, resulting in possible severe personal injury, death, or substantial property damage

WARNING

If the appliance combustion air inlet is located in a laundry room or pool facility, for example, these areas will always contain hazardous contaminants. Pool and laundry products and common household and hobby products often contain fluorine or chlorine compounds. When these chemicals pass through the appliance, they can form strong acids. The acid can eat through the appliance wall, causing serious damage and presenting a possible threat of flue gas spillage or water leakage into the building.
Please read the information listed in Table 1B. If contaminating chemicals will be present near the location of the appliance combustion air inlet, have your installer pipe the appliance combustion air and vent to another location, per the Armor Installation and Operation Manual.

WARNING

To prevent the potential of severe personal injury or death, check for areas and products listed in Table 1B before installing the appliance or air inlet piping. If contaminants are found, you MUST:

• Remove products permanently. —OR—
• Relocate air inlet and vent terminations to other areas

Table 1B Corrosive Contaminants and Sources

Products to avoid:

Spray cans containing chloro/fluorocarbons
Permanent wave solutions
Chlorinated waxes/cleaners
Chlorine-based swimming pool chemicals
Calcium chloride used for thawing
Sodium chloride is used for water-softening
Refrigerant leaks
Paint or varnish removers
Hydrochloric acid/muriatic acid
Cement and glues
Antistatic fabric softeners used in clothes dryers
Chlorine-type bleaches, detergents, and cleaning solvents found in household laundry rooms
Adhesives used to fasten building products and other similar products
Areas likely to have contaminants
Dry cleaning/laundry areas and establishments
Swimming pools
Metal fabrication plants
Beauty shops
Refrigeration repair shops
Photo processing plants
Auto body shops
Plastic manufacturing plants
Furniture refinishing areas and establishments
New building construction
Remodeling areas
Garages with workshops

WARNING

Follow the maintenance procedures given throughout this manual. Failure to perform the service and maintenance or follow the directions in this manual could result in damage to the appliance or system, resulting in severe personal injury, death, or substantial property damage

Maintenance procedures

The appliance must be serviced and maintained

WARNING The appliance must be inspected and started annually at the beginning of the heating season by a qualified service technician. In addition, the maintenance and care of the appliance designated on page 6 of this manual and explained on pages 7 through 8 must be performed to assure maximum appliance efficiency and reliability. Failure to service and maintain the appliance and system could result in equipment failure, causing possible severe personal injury, death, or substantial property damage.

NOTICE The following information provides detailed instructions for completing the maintenance items listed in the maintenance schedule on page 6. In addition to this maintenance, the appliance must be serviced and started up at the beginning of each heating season by a qualified service technician.

Check appliance area

WARNING To prevent the potential of severe personalinjury, death, or substantial property damage, eliminate all materials discussed below from the appliance vicinity and the vicinity of the appliance combustion air inlet. If contaminants are found:
Remove products immediately from the area. If they have been there for an extended period, call a qualified service technician to inspect the appliance for possible damage from acid corrosion. If products cannot be removed, immediately call a qualified service technician to re-pipe the vent and air piping and locate vent termination/air intake away from contaminated areas.

1. Combustible/flammable materials — Do not store combustible materials, gasoline, or any other flammable vapors or liquids near the appliance. Remove immediately if found.
2. Air contaminants — Products containing chlorine or fluorine, if allowed to contaminate the appliance intake air, will cause acidic condensate in the appliance. This will cause significant damage to the appliance if allowed to continue.Read the list of potential materials listed in Table 1B on page 5 of this manual. If any of these products are in the room from which the appliance takes its combustion air, they must be removed immediately or the appliance combustion air (and vent termination) must be relocated to another area.

Check vent piping

1. Visually inspect the flue gas vent piping for any signs of blockage, leakage, or deterioration of the piping. Notify your qualified service technician at once if you find any problems.

WARNING Failure to inspect the vent system as noted above and have it repaired by a qualified service technician can result in vent system failure, causing severe personal injury or death.

Check air piping

1. Inspect the appliance relief valve and the relief valve discharge pipe for signs of weeping or leakage.
2. If the relief valve often weeps, the expansion tank may not be working properly. Immediately contact your qualified service technician to inspect the appliance and system.

Check the condensate drain system

1. Inspect the condensate drain line, vent line, condensate PVC fittings, and condensate trap.

Flush condensate trap with water

1. Remove the four (4) screws securing the top cover to the condensate trap and remove the cover (FIG. 2-1).
2. Locate the plastic ball inside the float tube. Verify there is nothing under the ball causing it to not sit properly.
3. Fill with fresh water until the water begins to pour out of the drain.
4. Replace the top cover and the screws removed in Step 1.

Figure 2-1 Condensate Trap

Test low water cutoff (if installed)

1. If the system is equipped with a low water cutoff, test the low water cutoff periodically during the heating season, following the low water cutoff manufacturer’s instructions

Reset button (low water cutoff)

1. Testing the low water cutoff shuts the unit off. Press the RESET button on the low water cutoff to turn the unit back on

Check appliance piping (gas and water)

1. Remove the appliance’s front access door and perform a gas leak inspection per steps 1 through 7 of the Operating Instructions on page 9. If a gas odour or leak is detected, immediately shut down the appliance following the procedure on page 9. Call a qualified service technician.

2. Visually inspect for leaks around water piping. Also inspect the circulators, relief valve, and fittings. Immediately call a qualified service technician to repair any leaks.
   WARNING Have leaks fixed at once by a qualified service technician. Failure to comply could result in severe personal injury, death, or substantial property damage.

3. Replace the front access door.

Operate relief valve

1. Before proceeding, verify that the relief valve outlet has been piped to a safe place of discharge, avoiding any possibility of scalding from hot water
   WARNING To avoid water damage or scalding due to valve operation, a metal discharge line must be connected to the relief valve outlet and run to a safe place of disposal. This discharge line must be installed by a qualified heating installer or service technician in accordance with the instructions in the Armor Installation and Operation Manual. The discharge line must be terminated so as to eliminate the possibility of severe burns or property damage should the valve discharge.

2. Lift the relief valve top lever slightly, allowing water to be relieved through the valve and discharge piping.

3. If water flows freely, release the lever and allow the valve to seat. Watch the end of the relief valve discharge pipe to ensure that the valve does not weep after the line has had time to drain. If the valve weeps, lift the seat again to attempt to clean the valve seat. If the valve continues to weep afterwards, contact your qualified service technician to inspect the valve and system.

4. If water does not flow from the valve when you lift the lever completely, the valve or discharge line may be blocked. Immediately shut down the appliance, following the operating instructions on page 9 of this manual. Call your qualified service technician to inspect the appliance and system
