Only  properly  qualified  personnel  should  install  this  equipment.  Improper 
installation or installation by a non-qualified installer may void warranty. Failure to 
comply with state and local codes pertaining to water heater installations may void 
also warranty.
GA16ETL water heaters are suitable for installation as a single standalone unit or in 
installations involving combinations of multiple units (i.e. parallel or series). These 
guidelines are for the installation of a single unit. Please contact authorized service 
center for multiple device connection assistance.
This appliance shall NOT be installed outdoors. 
A qualified installer or service technician should inspect and leak test system before 
use.
The installation must comply with local codes. In the absence of local codes the 
National Fuel Gas Code, ANSI Z223.1/NFPA 54, or the Natural Gas and Propane 
Installation Code, CSA B149.1 shall prevail.
The appliance must be electrically grounded in accordance with local codes. In the 
event there are no local codes, the National Electrical Code, ANSI/NFPA 70, or the 
Canadian Electrical Code, CSA C22.1 shall prevail.
Maximum  inlet  gas  pressure  must  not  exceed  the  value  specified  by  the 
manufacturer and that the minimum value listed is for purposes of input adjustment.
Disconnect the heater and the heater main gas valve from the gas supply piping 
system during any pressure testing. Isolate the heater from the gas supply piping 
system by closing the inlet manual shutoff valve. The gas pressure will be between 
these values 3.5 in W.C. (870 Pa) 10.5 in W.C. (2610 Pa) for Natural Gas and 8.0 in 
W.C. (1990 Pa) 13.0 in W.C. (3230 Pa) for Liquid Propane.
The appliance should be located in an area where water leakage  of  the  unit  or 
connections will not result in damage. Take precaution by properly installing a drain 
pan under the heater if required to protect area where leakage would travel.
Do not obstruct the combustion air intake or heater exhaust and ensure air intake is 
not near an area that will allow chemical fumes to enter the combustion air system.
Do not use to heat pools or spas (hot tubs) that uses chemically treated water. 
If a water heater is installed in a closed water supply system, special precautions are 
required such as  installation  of  a backflow preventer  and  allowance  for thermal 
expansion. Consult an authorized professional for proper installation requirements.
