WARNING
FOR YOUR OWN SAFETY READ BEFORE OPERATING
1. This appliance does not have pilot. It is equipped with an ignition device which automatically lights the burner. Do not try to light the
burner by hand.
2. BEFORE OPERATING: smell all around the appliance area for gas. Be sure to smell next to the oor because some gas is heavier than air and will settle on
the oor.
WHAT TO DO IF YOU SMELL GAS
ㆍ
Do not try to light any appliance.
ㆍ
Do not touch any electric switch; do not use any phone in your building.
ㆍ
Immediately call your gas supplier from a neighbor's phone. Follow the gas suppliers' instructions.
ㆍ
If you cannot reach your gas supplier, call the re department.
ㆍ
Turn off gas shutoff valve (located outside of the appliance) so that the handle is crosswise to the gas pipe. If the handle will
not turn by hand, don't try to force or repair it, call a qualied service technician. Force or attempted repair may result in a re or
explosion.
4. Do not use this appliance if any part has been under water. Immediately call a qualied service technician to inspect the appliance and to replace any part of
the control system and any gas control that has been damaged.
5. The applianceshall be installed so the gas ignition system components are protected from water (dripping, spraying, rain, etc.) during appliance operation and
service (circulator replacement, condensate trap, control replacement, etc.)
Failure to follow these instructions could result in property damage, serious personal injury, or death.
If you discover any evidence of a gas leak, shut down the appliance at once. Find the leak source with a bubble test and repair immediately. Do not start the
appliance again until the leak is repaired. Failure to comply could result in substantial property damage, severe personal injury, or death.
Ensure the appliance is full of water before ring the burner. Failure to do so will damage the appliance. Such damage IS NOT covered by warranty, and could
result in property damage, severe personal injury, or death.
Eliminate all system leaks. Continual fresh make-up water will reduce appliance life. Minerals can build up in the heat exchanger, reducing heat transfer,
overheating the heat exchanger, causing heat exchanger failure and possibly resulting in property damage, severe personal injury, or death.
▪ D. FILL AND TEST WATER SYSTEM
▪ E. PURGE AIR FROM CH
1. Fill the system only after ensuring water chemistry meets the requirements listed in this manual.
2. Close the manual and automatic air vents and appliance drain valve.
3. Fill to the correct system pressure. Correct pressure will vary with each application.
a. Typical cold water ll pressure for a CH residential system is 12 psi.
b. Pressure will rise when appliance is turned on and system water temperature increases. Operating pressure of the CH system should never
exceed 25 psi, and must never exceed the relief valve pressure setting.
4. At initial ll and during appliance startup and testing, check system thoroughly for leaks. Repair all leaks before proceeding further.
5. The system may have residual substances that could affect water chemistry. After the system has been lled and leak tested, verify that water pH
and chlorine concentrations are acceptable by sample testing.
It is important to purge the system of air to avoid damage to the appliance
CAUTION
CAUTION
IMPORTANT! While commissioning the system, the air vent on top of the appliance must remain fully open to allow the appliance to properly ll.
Failure to keep the air vent open could lead to improper appliance and system operation.
