SAFE INSTALLATION, USE AND SERVICE
The proper installation, use and servicing of this boiler is extremely important to your safety and the safety of others.
This is the safety alert symbol. It is used to alert you to potential personal injury hazards. Obey all safety messages that follow this symbol to avoid possible injury or death.
DANGER indicates an imminently
DANGER hazardous situation which, if not avoided, will result in injury or death.
WARNING indicates a potentially hazardous
WARNING situation which, if not avoided, could result in injury or death.
CAUTION indicates a potentially hazardous
CAUTION situation which, if not avoided, could result in minor or moderate injury.
CAUTION used without the safety alert CAUTION symbol indicates a potentially hazardous
situation which, if not avoided, could result in property damage.
All safety messages will generally tell you about the type of hazard, what can happen if you do not follow the safety message, and how to avoid the risk of injury.
The California Safe Drinking Water and Toxic Enforcement Act requires the Governor of California to publish a list of substances known to the State of California to cause cancer, birth defects, or other reproductive harm, and requires businesses to warn of potential exposure to such substances.
This product contains a chemical known to the State of California to cause cancer, birth defects, or other reproductive harm. This boiler can cause low level exposure to some of the substances listed in the Act.
Natural Gas or Propane Utility or service who supplies gas for utilization by the gas burning
application. The gas
supplier typically has responsibility for the inspection and
code approval of
and including the Natural
Gas meter or Propane storage tank of a building. Many
gas suppliers also
offer service and inspection of appliances within the building.
HIGH ALTITUDE INSTALLATIONS
This boiler must be grounded in accordance with the National Electrical Code, Canadian Electrical Code and/or local codes. Boiler is polarity sensitive; correct wiring is imperative for proper operation.
This boiler must be connected to a grounded metal, permanent wiring system, or an equipment grounding conductor must be run with the circuit conductors and connected to the equipment grounding terminal or lead on the boiler.
INLET WATER CONSIDERATIONS
Circulating water through the boiler and to the remote storage tank (if applicable) is accomplished by a pump on XW models only. For hot water heating systems using the XB model, the circulating pump is NOT provided on standard models (optional) and must be field installed.
Make sure the gas on which the boiler will operate is the same as that specified on the boiler rating plate. Do not install the boiler if equipped for a different type of gas; consult your supplier.
If the unit is exposed to the following, do not operate until all corrective steps have been made by a qualified service agent:
1.Exposure to fire.
3.Firing without water.
If the boiler has been exposed to flooding, it must be replaced.
LIQUEFIED PETROLEUM GAS MODELS
Boilers for propane or liquefied petroleum gas (LPG) are different fromnaturalgasmodels.Anaturalgasboilerwillnotfunctionsafely on LPgas and no attempt should be made to convert a boiler from natural gas to LP gas.
LP gas must be used with great caution. It is highly explosive and heavier than air. It collects first in the low areas making its odor difficult to detect at nose level. If LP gas is present or even suspected, do not attempt to find the cause yourself. Leave the building, leaving doors open to ventilate, then call your gas supplier or service agent. Keep area clear until a service call has been made.
At times you may not be able to smell an LP gas leak. One cause is odor fade, which is a loss of the chemical odorant that gives LP gas its distinctive smell. Another cause can be your physical condition, such as having a cold or diminishing sense of smell with age. For these reasons, the use of a propane gas detector is recommended.
If you experience an out of gas situation, do not try to relight appliances yourself. Call your local service agent. Only trained LP professionals should conduct the required safety checks in accordance with industry standards.
Rated inputs are suitable up to 2000 feet (610 m) elevation. Consult the factory for installation at altitudes over 2000 feet (610 m).
FIELD INSTALLED COMPONENTS
When installing the boiler, the following components must be installed:
•Circulating Pump (Hydronic)
•Remote Temperature Sensor/Header Sensor
•Storage Tank (Temperature & Pressure Relief Valve)
