OWNER'S OPERATING
INSTRUCTIONS
Start-Up Procedures
Before Start-Up
Burners
Clean main burners and air louvers of dust, lint and
debris. Keep heater area clear and free from com-
bustibles, flammable liquids and chemicals. Do not
obstruct the flow of combustion and ventilation air.
Water
First thing, ensure that system is filled with water and
have pump operating. Water must be flowing through
the heater during operation.
After Start-Up
Feel the inlet and outlet pipes. Outlet pipe should be
only slightly warmer than the inlet. It should not be hot.
Visual Inspection
With the heater on, remove the door and make a visu-
al check of the pilot and burner. The flame should be
blue with a well-defined pattern.
A yellow or "floating" flame indicates restricted air
openings or incorrect orifice size. Should this occur,
shut the heater off and contact your installer or gas
supplier.
Water Pressure Switch
A water pressure switch is provided in the heater to
shut-off the burners in the event that water supply to
the heater is interrupted. It is very important to verify
that the switch electrically opens and shuts off the gas
WARNING:
If you do not follow these instructions
exactly, a fire or explosion may result, causing
property damage, personal injury or loss of life.
WARNING:
Should overheating occur or the gas
supply fail to shut off, turn off the manual gas control
to the appliance.
