FOREWORD
These designs comply with the latest edition of the American National Standards for
Detailed installation diagrams are found in this manual. These diagrams will serve to provide the installer a reference for the materials and methods of piping necessary. It is essential that all water, gas piping and wiring be installed as shown on the diagrams. You should thoroughly read and understand this manual before installation and/or operation of this boiler.
The factory warranty will be void if the boiler(s) have been improperly installed or operated.
In addition to these instructions, the boiler(s) shall be installed in accordance with those installation regulations in force in the local area where the installation is to be made. These shall be carefully followed in all cases. Authorities having jurisdiction should be consulted before installations are made.
In the absence of local codes, the installation must comply with the latest editions.
In the United States:
The National Fuel Gas Code, ANSI Z223.1/NFPA 54 and the National Electric Code, NFPA 70.
In Canada:
The installation Code CAN/CSA B149.1 and .2 (latest edition) and the Canadian Electric Code, CSA C22.2.

GROUNDING INSTRUCTIONS
This boiler must be grounded in accordance with the National 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.
WARNING
YOUR BOILER IS NOT DESIGNED TO OPERATE WITH A BOILER INLET WATER TEMPERATURE OF LESS THAN 120°F (38°C).
COLDER INLET WATER TEMPERATURE WILL RESULT IN SIGNIFICANT CONDENSATION DEVELOPING ON THE HEAT EXCHANGER. THIS SITUATION CAN CAUSE A CORROSIVE ENVIRONMENT FOR THE HEAT EXCHANGER, BURNERS AND VENTING RESULTING IN PREMATURE DAMAGE, WHICH COULD RESULT IN SERIOUS PERSONAL INJURY OR DEATH.
FOR SYSTEMS THAT USE LARGE VOLUMES OF COLD WATER OR SYSTEMS UTILIZING HEAVY WATER DRAWS, CONDENSATION CAN BE PREVENTED BY USING A BYPASS LOOP.
CORRECT GAS
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 gas supplier.
PRECAUTIONS
IF THE UNIT IS EXPOSED TO THE FOLLOWING, DO NOT OPERATE UNTIL ALL CORRECTIVE STEPS HAVE BEEN MADE BY A QUALIFIED SERVICEMAN:
1.EXPOSURE TO FIRE.
2.IF DAMAGED.
3.FIRING WITHOUT WATER.
4.SOOTING.
IF THE BOILER HAS BEEN EXPOSED TO FLOODING, IT MUST BE REPLACED.
LIQUID PETROLEUM MODELS
Boilers for propane or liquefied petroleum gas (LPG) are different from natural gas models. A natural gas boiler will not function safely on LP gas 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.
HIGH ALTITUDE INSTALLATION
WARNING
INSTALLATIONS ABOVE 4,500 FEET REQUIRE REPLACEMENT OF THE BURNER ORIFICES IN ACCORDANCE WITH THE NATIONAL FUEL GAS CODE (ANSI/NFPA 54). FAILURE TO REPLACE THE ORIFICES WILL RESULT IN IMPROPER AND INEFFICIENT OPERATION OF THE APPLIANCE, PRODUCING CARBON MONOXIDE GAS IN EXCESS OF SAFE LIMITS, WHICH COULD RESULT IN SERIOUS PERSONAL INJURY OR DEATH.
GENESIS BOILERS ARE EQUIPPED WITH
Some utility companies derate their gas for altitude. You should contact your gas supplier for any specific changes which may be required in your area. Call the local gas utility to verify BTU content of the gas supplied.
Ratings specified by manufacturers for most boilers apply for elevations up to 4,500 feet (1350 m). For elevations above 4,500 feet (1350 m) ratings must be reduced by a rate of 4% for each 1,000 feet (300 m) above sea level.
