Address reported problems
1. Inspect any problems reported by the owner and
correct before proceeding.
Inspect water heater area
1. Verify that water heater area is free of any combustible
materials, gasoline and other flammable vapors and
liquids.
2. Verify that air intake area is free of any of the
contaminants listed in Section 1 - Determine Water
Heater Location. If any of these are present in the water
heater intake air vicinity, they must be removed. If
they cannot be removed, reinstall the air and vent lines
per this manual and the Armor Water Heater Service

components. Remove any obstructions.
Clean condensate trap
1. Inspect the condensate drain line, condensate PVC
fittings, and condensate trap.
Monthly inspection:
1. The condensate trap should be inspected monthly to
ensure the trap is properly installed and connected to
the condensate pipe under the appliance, see FIG. 13-1.
2. The condensate line should be inspected monthly
for obstructions, making sure it allows free flow for
condensate to drain.
3. Inspect the neutralizing kit (if installed) monthly to
ensure the condensate is draining properly, and there is
still an adequate amount of neutralizing agent available.

case there is no condensate in the trap. If this ball is not
present, flue gases may be able to pass through the trap
when there is no condensate present, resulting in an unsafe
environment. It is important to check and make sure the
ball is still located in the trap, acting as a seal against flue
gases at least once annually and after every cleaning.
