The temperature of the water in the hot water boiler
can be regulated by setting the temperature dial on
front of the thermostat. To comply with safety regula-
tions the thermostat was set at its lowest setting before
the hot water boiler was shipped from the factory. The
illustration below shows the thermostat and how to
adjust the water temperature.
To adjust the water temperature, insert a small straight
screwdriver into slotted screw in hole in front of ther-
mostat and turn wheel to desired setting.

Equipment Base
The boiler should be mounted on a level, structurally
sound surface. The boiler is approved for and can be
installed on a combustible surface but must NEVER
be installed on carpeting. Gas fueled equipment
installed in enclosed parking garages must be located
at least 18 inches above the floor.
CAUTION: The boiler should be located in an area
where water leakage will not result in damage to the
area adjacent to the appliance or to the structure.
When such locations cannot be avoided, it is
recommended that a suitable catch pan, adequately
drained, be installed under the appliance. The pan
must not restrict air flow.
In addition, the boiler shall be installed such that the
gas ignition system components are protected from
water (dripping, spraying, rain, etc.) during appliance
operation and service (circulator replacement, control
replacement, etc.).
