2 Prepare water heater
Remove water heater from wood pallet
1. After removing the outer shipping carton from the water
heater, remove the parts box.
2. To remove the water heater from the pallet:
a. Remove the two (2) lag bolts securing the bottom
of the unit to the pallet.
b. Lift the water heater off the wall bracket mounted to
the pallet.
3. Remove the two (2) lag bolts securing the wall bracket to
the wood pallet. Be certain not to lose the wall bracket as
it will be needed for securing the water heater to the wall
(FIG. 2-1).
Do not drop the water heater or bump the
jacket on the floor or pallet. Damage to
the water heater can result.
The gas conversion procedure should be
accomplished BEFORE the water heater
is installed. For a water heater already
installed, you must turn off gas supply,
turn off power, and allow the water heater
to cool before proceeding. You must
also completely test the water heater
after conversion to verify performance as
described under Start-up, Section 10 of
this manual.
You must install the propane orifice to fire
the Armor wall mount water heater on
propane. Verify when installing that the
orifice size marking matches water heater
size (Table 2A). Failure to comply could
result in severe personal injury, death, or
substantial property damage.
1. Remove the front access cover from the unit (no tools
required for removal).
2. Disconnect the ribbon cable from the control board.
Remove the four (4) screws securing the bezel to the front
of the unit and remove the bezel.
3. Disconnect the Molex plug from the wiring connector
located on the gas valve.
4. Using a 5/16" nut driver, loosen the band clamp securing the
air intake coupler to the gas valve venturi. Remove the air
intake pipe and coupler from the gas valve venturi.
5. Using a 4mm Allen wrench, remove the two (2) screws
securing the gas valve venturi to the inlet of the combustion
blower (FIG. 2-2). Remove the gas valve venturi assembly
from the unit.
