PART 1 – PRODUCT AND SAFETY INFORMATION
USER – Have this boiler serviced/inspected by a qualified service technician annually.
TO TURN OFF GAS TO THE BOILER
1. Set the thermostat to the lowest setting.
2. Turn off all electrical power to the boiler.
3. Turn manual gas shutoff valve to “OFF”.
Proper care of this boiler is the user’s / owner’s responsibility. The user / owner should carefully read and understand the Operating
Information in this manual before operating this boiler.
It is the user / owner’s responsibility to know the location of the gas shut-off valve and how to operate it. Immediately close the gas
shut-off valve if the boiler is subjected to fire, overheating, flood, physical damage, or any other damaging condition that might affect the
operation of the unit. Have the boiler checked by a qualified technician before resuming operation.
DO NOT use this boiler if ANY part has been under water. Immediately call a qualified technician to inspect the boiler and replace any
part of the control system or gas control which has been under water.
DO NOT power up the boiler unless the gas and water supply valves are fully opened. Make sure the fresh air intake pipe and exhaust
vents are open and functional.
DO NOT attempt to install, repair, or service this boiler. Contact a qualified technician if the boiler needs repair or maintenance. Ask
your gas supplier for a list of qualified service providers.
DO NOT use spray paint, hair spray, or any other flammable sprays near the boiler or near the exterior fresh air intake pipe termination.
DO NOT place any items in or around the exterior exhaust vent termination and/or fresh air intake pipe that could restrict or block the
flow in or out of the vent system.
All safety devices must be tested by the installer / service technician after the boiler is installed.
Always verify proper boiler operation with the service technician after servicing.
The gas ignition system components must be protected from water (dripping, spraying, rain, etc.) during boiler operation and service
(circulator replacement, condensate trap, control replacement, etc.)
The Er:80 code will display when there is no water in the boiler. Ensure the boiler is full of water and all air has been purged from the
system. Then manually reset the boiler to resume operation. If the Er:80 code displays again, call a qualified service technician to
inspect the boiler.
This boiler features a factory installed overheating prevention device. This limit provides boiler shutdown in the event that the boiler
water temperature exceeds the set point of the limit control. Certain local codes require additional water temperature limiting devices.
FAILURE TO ADHERE TO THE GUIDELINES IN THIS MANUAL CAN RESULT IN SUBSTANTIAL PROPERTY DAMAGE, SEVERE
PERSONAL INJURY, OR DEATH.
A. BEFORE OPERATION
1. Check the Gas Type (NG/LP)
When operating the boiler for the first time, ensure the connected gas type matches that of the gas type of the boiler. Check
whether the gas supplied is NG or LP. The boiler gas type is indicated on the rating plate on the side of the boiler.
Attempting to operate this boiler on a gas supply other than specified on the rating plate will result in improper boiler operation, and
could result in property damage or personal injury.
2. Check the Power (120V 60Hz)
Ensure the boiler is connected to a properly rated power supply.
3. Check the Automatic Feed Valve
Ensure the automatic feed valve to the boiler is providing the proper pressure to the central heating (CH) loop.
4. Check the Gas Shut-Off Valve
Ensure the manual gas shut-off valve is open. The boiler will not operate unless it is supplied with gas.
5. Check the Area around the Boiler
Remove any combustible or flammable materials from the area around the boiler and do not hang anything from the exhaust
vent pipe.
Do not operate the boiler if its combustion air intake is located in or near one of the areas or in the vicinity of products listed in Table 1.
These areas will always contain hazardous contaminates that can form strong acids while passing through the burner and vent system.
These acids will corrode the boiler’s heat exchanger, burner components and vent system, resulting in flue gas spillage and/or water
leakage, possible substantial property damage, severe personal injury, or death. If the boiler combustion air intake is located in any
area likely to cause or contain contamination, or if products which would contaminate the air cannot be removed, the intake must be re-
piped and terminated to another location.
DO NOT re-pipe the combustion ventilation system on your own. Call a qualified service provider for assistance.
