Some addition adjustment maybe required later to maintain 

a steady gas supply pressure.

5.  When  installing  multiple  water  heaters  in  the  same  gas 

supply  system  it  is  recommended  that  individual  positive 

lock-up gas pressure regulators be installed at each unit.

POWER SUPPLY

The water heaters covered in this manual require a 120 VAC, 

1Ø (single phase), 60Hz, 15 amp power supply and must also 

be electrically grounded in accordance with local codes or, in the 

absence of local codes, with the National Electrical Code, ANSI/

NFPA 70 or the Canadian Electrical Code, CSA C22.1.

WATER TEMPERATURE CONTROL AND MIXING VALVES

Water temperature over 125°F (52°C)

can cause severe burns instantly

resulting in severe injury or death.
Children, the elderly and the

physically or mentally disabled are at

highest risk for scald injury.
Feel water before bathing or

showering.
Temperature limiting devices such as

mixing valves must be installed

when required by codes and to

ensure safe temperatures at fixtures.

Water heated to a temperature which will satisfy clothes washing, 

dish washing, and other sanitizing needs can scald and cause 

permanent  injury  upon  contact.  Short  repeated  heating  cycles 

caused by small hot water uses can cause temperatures at the 

point of use to exceed the water heater’s temperature setting by 

up to 20°F (11°C).
Some  people  are  more  likely  to  be  permanently  injured  by 

hot  water  than  others. These  include  the  elderly,  children,  the 

infirm  and  the  physically/mentally  disabled. Table  5  shows  the 

approximate  time-to-burn  relationship  for  normal  adult  skin. 

If  anyone  using  hot  water  provided  by  the  water  heater  being 

installed fits into one of these groups or if there is a local code 

or state law requiring a certain water temperature at the point of 

use, then special precautions must be taken.
In addition to using the lowest possible temperature setting that 

satisfies the demand of the application a Mixing Valve should be 

installed at the water heater (see Figure 10) or at the hot water 

taps to further reduce system water temperature.
Mixing valves are available at plumbing supply stores. Consult 

a  Qualified  Installer  or  Service  Agency.  Follow  mixing  valve 

manufacturer’s instructions for installation of the valves.

GAS SUPPLY SYSTEMS

Low pressure building gas supply systems are defined as those 

systems that cannot under any circumstances exceed 14” W.C. 

(3.49  kPa)  (1/2  PSI  Gauge).  These  systems  do  not  require 

pressure regulation. Measurements should be taken to insure 

that gas pressures are stable and fall within the requirements 

stated  on  the  water  heater  rating  plate.  Readings  should  be 

taken with all gas burning equipment off (static pressure) and 

with all gas burning equipment running at maximum rate (dynamic 

pressure). The gas supply pressure must be stable within 1.5” 

W.C. (0.37 kPa) from static to dynamic pressure to provide good 

performance. Pressure drops that exceed 1.5” W.C. (0.37 kPa) 

may cause rough starting, noisy combustion or nuisance outages. 

Increases  or  spikes  in  static  pressure  during  off  cycles  may 

cause failure to ignite or in severe cases damage to appliance 

gas valves. If your low pressure system does NOT meet these 

requirements, the installer is responsible for the corrections.
High Pressure building supply systems use pressures that exceed 

14” W.C. (3.49 kPa) (1/2 PSI Gauge). These systems must use 

field supplied regulators to lower the gas pressure to less than 

14” W.C. (3.49 kPa) (1/2 PSI Gauge). Appliances require gas 

regulators that are properly sized for the water heater input and 

deliver the rating plate specified pressures. Gas supply systems 

where pressure exceeds 5 PSI (34.5 kPa) often require multiple 

regulators  to  achieve  desired  pressures.  Systems  in  excess 

of 5 PSI building pressure should be designed by gas delivery 

professionals for best performance. Water heaters connected to 

gas supply systems that exceed 14” W.C. (3.49 kPa) (1/2 PSI 

Gauge) at any time must be equipped with a gas supply regulator.

GAS PRESSURE REQUIREMENTS

All models require a minimum gas supply pressure as shown in 

Table 3 on page 8. The minimum supply pressure is measured 

while  gas  is  flowing  (dynamic  pressure).  The  supply  pressure 

(dynamic) should never fall below that indicated in Table 3 page 

8. The  supply  pressure  should  be  measured  with  all  gas  fired 

appliances connected to the common main firing at full capacity. 

If  the  supply  pressure  drops  more  than  1.5”  W.C.  (0.37  kPa) 

as gas begins to flow to the water heater then the supply gas 

system including the gas line and/or the gas regulator may be 

restricted or undersized. See Supply Gas Regulator section and 

Gas Piping section of this manual. 
The gas control valve on all models has a maximum gas supply 

pressure  limit  of  14"  W.C.  (3.48  kPa).  The  maximum  supply 

pressure is measured while gas is not flowing (static pressure).

SUPPLY GAS REGULATOR

The  maximum  allowable  gas  supply  pressure  for  this  water 

heater is 14 inches W.C. (3.48 kPa). Install a positive lock-up gas 

pressure regulator in the gas supply line if inlet gas pressure can 

exceed 14 inches W.C. (3.48 kPa) at any time. Regulators must 

be sized/used according to manufacturer's specifications.
If a positive lock-up regulator is required follow these instructions:

1.  Positive lock-up gas pressure regulators must be rated at or 

above the input Btu/hr rating of the water heater they supply.

2.  Supply gas regulators shall have inlet and outlet connections 

not less than the minimum supply gas line size for the water 

heater they supply. See Table 7 on page 24.

3.  Positive  lock-up  gas  pressure  regulator(s)  should  be 

installed no closer than 3 feet (1 meter) and no farther than 8 

feet (2.4 meters) of equivalent length from the water heater’s 

inlet gas connection.

4.  After installing the positive lock-up gas pressure regulator(s) 

an initial nominal supply pressure setting of 7.0” W.C. (1.74 

kPa)  while  the  water  heater  is  operating  is  recommended 

and  will  generally  provide  good  water  heater  operation.
