INSTALLING YOUR GAS WATER HEATER

Important Information About This Water Heater 

      

This gas water heater was manufactured to voluntary 

safety standards to reduce the likelihood of a flammable 

vapor ignition incident. New technology used in meeting 

these standards makes this product more sensitive to 

installation errors or improper installation environments. 

Please review the Installation Checklist found at the end of 

the installation instructions section and make any required 

installation upgrades or changes.

Consumer Responsibilities

                                    

This manual has been prepared to acquaint you with the 

installation, operation, and maintenance of your gas water 

heater and provide important safety information in these 

areas. 
Read all of the instructions thoroughly before attempting 

the installation or operation of this water heater. 
Do not discard this manual. You or future users of this

Service to the FVIR System should only be performed by a 

qualified technician.
Examples of a qualified technician include: licensed 

plumbers, authorized gas company personnel, and 

authorized service personnel.
IMPORTANT: The manufacturer and seller of this water 

heater will not be liable for any damages, injuries, or 

deaths caused by failure to comply with the installation and 

operating instructions outlined in this manual. 
If you lack the necessary skills required to properly install 

this water heater, or you have difficulty following the 

instructions, you should not proceed but have a qualified 

technician perform the installation of this water heater. 

Massachusetts code requires this water heater to be 

installed in accordance with Massachusetts Plumbing and 

Fuel Gas Code 248 CMR Section 2.00 and 5.00.

Unpacking the Water Heater                                   

Excessive Weight Hazard

WARNING

Use two or more people to move and install the water heater.
Failure to do so can result in injury (including back injury).

IMPORTANT: Do not remove any permanent instructions, 

labels, or the data label from either the outside of the 

water heater or on the inside of water heater panels.
• 

Remove exterior packaging and place installation com-

ponents aside.

• 

Inspect all parts for damage prior to installation and 

start-up.

• 

Completely read all instructions before attempting to 

assemble and install this product.

• 

After installation, dispose of/recycle all packaging 

materials.

Location Requirements

                                              

Carbon Monoxide Poisoning Hazard

WARNING

Do not install in a mobile home.  

Doing so can result in carbon monoxide poisoning and death.  

The Flammable Vapor (FV) Sensor is designed to reduce 
the risk of flammable vapor-related fires. Flammable liquids 
(such as gasoline, solvents, propane, etc,) emit flammable 
vapors which can be ignited by a gas water heater’s spark 
igniter or main burner. The resulting flashback and fire can 
cause death or serious burns to anyone in the area.
This heater is equipped with an FV sensor for detecting the 
presence of flammable vapors. When the sensor detects 
those vapors, the unit will shut down and not operate. 
Should this happen, please refer to the troubleshooting 
guide. Even though this water heater is a flammable vapors 
ignition resistant water heater and is designed to reduce 
the chances of flammable vapors being ignited, gasoline 
and other flammable substances should never be stored 
or used in the same vicinity or area containing a gas water 
heater or other open flame or spark producing appliance. 
In the event the FV Sensor does not prevent the ignition of 
flammable vapors, the FVIR System is designed to reduce 
the risk of flammable vapor-related fires.
