Installation & Operation Manual
10 Start-up
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, page 55 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. 10-2 on
page 55.
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 tank
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.
 Check vent piping and air piping
1. Check for gastight seal at every connection, seam of air
piping, and vent piping.
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).
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.
DO NOT adjust 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
the gas valve outlet pressure could result
in damage to the valve, causing potential
severe personal injury, death, or substantial
property damage.
Check flame and combustion
1. Remove the flue temperature sensor from the flue pipe
connection. Note: Combustion measurements will be
made at this point.
⚠WARNING
⚠WARNING
⚠WARNING
⚠WARNING
Armor wall mount 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 (see pages 12 thru 13).
In order to operate on LP gas, an orifice
MUST BE installed. Failure to comply could
result in severe personal injury, death, or
substantial property damage.
