OPERATING INSTRUCTIONS
TO OPERATE MAIN BURNER
Be sure water is flowing through water heater coil before turning on burner switch. Start the
pumping unit involved until a steady stream of water is flowing from the spray gun.
Turn burner switch to “On” position. Burner will ignite and remain in operation as long as there
is sufficient water flow to satisfy the pressure switch and temperature limit control. To shut off
main burner, turn burner switch to “Off”. For complete shutdown of the water heater, turn knob
on combination gas valve to “Off” position. Should the pilot outage occur, turn automatic gas
valve to “Off”. Wait 5 minutes to clear combustion chamber of accumulated gas and retry.
CONDENSATION FROM COIL
When cold water is being pumped through the heater coil and the burner is firing, condensation
may form at times on the coil and drip down the burner compartment. This can be particularly
noticeable on cold, humid days giving the false appearance of a leaking coil. A leaking coil is
identified by a continuously cycling pump. With the wand trigger off, the pressure gauge should
read 0 with no flow.
TO CHECK HEATER COILS FOR LEAKS
Start the pumping unit and allow it to run for a few minutes with the burner “Off”. Check the
burner compartment with a trouble light or flash light. If no leaks are visible, this will confirm
that occasional water dripping from the coil is due to condensation of the flue gases, when the
burner is firing.
GENERAL MAINTENANCE AND CARE
WINTERIZATION
If the water heater is likely to be exposed to freezing weather, then it should be winterized with
anti-freeze. Circulation of the anti-freeze solution through the coil by means of the pump is the
most fail-safe method.
WATER CONDITION
Use a softener on your water system if local water is known to be high is mineral content. The
advantages of soft water are very beneficial. Prevents scale buildup in heater coil, cleans better
with considerably less detergent, prevents streaking on painted surfaces and glass when rinsing.
