stand, verify the following:
Are all bolted connections and setscrews tightened sufciently?
Is the tank/stand assembly level and stable?
Will there be adequate clearances to combustibles? (Refer to the heater
rating plate or installation manual.)
Will there be any structural interferences with the heater in place?
7. After the heater is set on the stand and before proceeding with the
installation, attach angle stops to the heater cabinet.
If installing a Model RV, attach the angle stops to the bottom of the heater.
(See the illustration in Step 4, page 3, that appllies to Model RV.)
If installing a Model RA 150 or 250, center the heater front to back on the
stand and attach the angle stops to the sides of the heater. (See the illustration
in Step 4, page 3, that applies to Model RA 150 and 250.)
If installing a Model OH 95, 140, 190 or RA 110, 140, 235, the unit ts between
the rails and does not require that the stops be attached to the heater. However, the screws are included and may be used to attach the angle stops to the
sides of the heater
