Final checks before starting the water heater

Read the Armor Water Heater Service Manual to familiarize yourself with SMART SYSTEM control module operation. Read this manual, pages 55 and 56 for proper steps to start the water heater.

Verify the water heater and system are full of water and all system components are correctly set for operation.

Verify the preparation procedures of Section 10, pages 53 and 54 have been completed.

Fill the vent condensate trap with water (removing the retaining screw in order to remove the 2 inch PVC cap with the switch located at the top of the trap). Replace the cap. Press the cap onto the trap until the cap makes contact with the drain. Replace the retaining screw.

Verify electrical connections are correct and securely attached.

Inspect vent piping and air piping for signs of deterioration from corrosion, physical damage or sagging. Verify air piping and vent piping are intact and correctly installed per this manual.

Start the water heater

1.Read and follow the Operating instructions in FIG.’s 10-2 and 10-3, pages 55 and 56.

If water heater does not start correctly

1.Check for loose connections, blown fuse or service switch off?

2.Is water heater water temperature above 200°F?

3.Is tank thermostat or tank set point set below room temperature?

4.Is gas turned on at meter or water heater?

5.Is incoming gas pressure less than 4 inches w.c.?

If none of the above corrects the problem, refer to the Troubleshooting Section of the Armor Water Heater Service Manual.

Check system and water heater

Check water piping

1.Check system piping for leaks. If found, shut down the water heater and repair immediately. (See WARNINGS on pages 53 and 54 (startup) regarding failure to repair leaks.)

2.Check Delta T. Reference Section 6 - System Piping on page 38 for more information regarding Delta T.

3.Vent any remaining air from the system using manual vents. Air in the system will interfere with circulation and cause heat distribution problems and noise.

Installation & Operation Manual

Check vent piping and air piping

1.Check for gastight seal at every connection, seam of air piping, and vent piping.

￿WARNING Venting system must be sealed gastight to prevent flue gas spillage and carbon

monoxide emissions, which will result in severe personal injury or death.

Check gas piping

1.Check around the water heater for gas odor following the procedure on page 44 of this manual (Connecting Gas Supply Piping).

￿WARNING If you discover evidence of any gas leak, shut down the water heater at once. Find

the leak source with a bubble test and repair immediately. Do not start the water heater again until corrected. Failure to comply could result in severe personal injury, death, or substantial property damage.

Propane water heaters – verify conversion

1.Verify propane conversion has been completed per the Propane Conversion instructions.

￿WARNING DO NOT adjust or attempt to measure gas valve outlet pressure. The gas valve is

factory-set for the correct outlet pressure. This setting is suitable for natural gas and propane, requiring no field adjustment. Attempting to alter or measure the gas valve outlet pressure could result in damage to the valve, causing potential severe personal injury, death, or substantial property damage.

￿WARNING Armor water heaters are typically shipped ready to fire on natural gas. Check water

heater rating plate to determine which fuel the water heater is set for. If set to natural gas, it may be converted to LP by installing an orifice or by making a gas valve adjustment (see pages 13 thru 15). In order to operate on LP gas, an orifice MUST BE installed or a gas valve adjustment MUST BE made. Failure to comply could result in severe personal injury, death, or substantial property damage.

Check flame and combustion

1.Turn the main power off to the water heater by placing the “On/Off” switch in the OFF position.

2.Remove the flue temperature sensor from the flue pipe connection. Note: Combustion measurements will be made at this point.

3.Turn the main power on to the water heater by placing the “On/Off” switch in the ON position.
