Models 151 - 286

1.

Remove the top and front access covers from the unit (no

 

tools required for removal).

2.

Remove the three screws securing the gas valve to the

 

venturi (FIG. 2-2).

3.

Locate the propane orifice disk from the conversion kit bag.

 

Verify that the stamping on the orifice disk matches the

 

water heater size (151 – 286) (see Table 2A above).

 

Place the orifice into the black rubber grommet in the side

 

of the gas valve and secure in the valve (FIG. 2-2).

4.

Reposition the gas valve against the venturi and replace the

 

screws (FIG. 2-2) securing the valve to the venturi.

5.

After installation is complete, attach the propane conversion

 

label (in the conversion kit bag) next to the water heater

 

rating plate. Attach the LP caution label (in the conversion

 

kit bag) to the left side of the unit in the lower left corner.

6.

Replace the top and front access covers.

 

After converting to LP, check combustion

￿ WARNING

￿WARNING

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. Failure to comply could result in severe personal injury, death, or substantial property damage.

For Models 151 - 400 you must install a propane orifice to operate the Armor water heater on propane gas. Verify when installing that the orifice size marking matches water heater size (Models 151 – 400, Table 2A).

The 501 - 801 Models do not require an orifice installation for propane operation, but they will require a valve adjustment.

per the Start-up procedure in Section 10

of this manual. Failure to check and verify combustion could result in severe personal injury, death, or substantial property damage.
