WARNING  
RELIEF VALVE  
Using other vent or air intake materials, failure  
to properly seal all seams and joints or failure to  
follow vent pipe manufacturer's instructions can  
result in personal injury, death or property  
damage. Mixing of venting materials will void  
the warranty and certification of the appliance.  
This appliance is supplied with a relief valve(s) sized in  
accordance with ASME Boiler and Pressure Vessel Code,  
Section IV ("Heating Boilers"). The relief valve(s) is  
installed in the vertical position and mounted in the hot  
water outlet. No valve is to be placed between the relief  
valve, and the appliance. To prevent water damage, the  
discharge from the relief valve shall be piped to a suitable  
floor drain for disposal when relief occurs. No reducing  
couplings or other restrictions shall be installed in the  
discharge line. The discharge line shall allow complete  
drainage of the valve and line. Relief valves should be  
manually operated at least once a year.  
IMPORTANT:

APPLIANCES  
VENT SYSTEM OPTIONS  
This appliance has five venting options. They are:  
Provisions for combustion and ventilation air must be in  
accordance with Section 5.3, Air for Combustion and  
Ventilation, of the latest edition of the National Fuel Gas  
Code, ANSI Z223.1, in Canada, the latest edition of CGA  
Standard B149 Installation Code for Gas Burning  
Appliances and Equipment, or applicable provisions of the  
local building codes.  
1. Conventional Negative Draft Venting  
Conventional negative draft venting with vertical  
termination.  
2. E+ with a Vertical Conventional Vent  
E+Vent with a vertical conventional vent for flue  
products and a combustion air pipe from either the  
sidewall or roof top.  
ƽ
CAUTION  
3. Direct Venting with Sidewall Terminations  
Direct vent with sidewall terminations for flue  
products and combustion air.  
Under no circumstances should the equipment room  
ever be under a negative pressure. Particular care  
should be taken where exhaust fans, attic fans, clothes  
dryers, compressors, air handling units, etc., may take  
away air from the unit.  
4. Direct Venting with Vertical Terminations  
Direct vent with vertical through-roof  
terminations for flue products and combustion air.  
E+ Vent and Direct Vent Units  
5. Outdoor Installation  
Outdoor installation consists of the installation of  
a special vent cap / top assembly, gas valve cover,  
deflectors, and a weatherproof junction box.  
These optional venting systems use two pipes, one pipe to  
exhaust flue products and one pipe to supply combustion  
air directly to the appliance. The optional vent systems  
have specific material and installation requirements. The  
combustion air pipe for the optional vent systems may  
terminate horizontally with a sidewall air inlet or vertically  
with a rooftop air inlet, based on the venting system  
installed. A detailed explanation of the installation  
requirements for each venting system, components used  
and part numbers of vent kits for each model is included in  
the Installation and Service Manual. No additional  
combustion air openings are required for the mechanical  
room when the optional two pipe venting systems are  
properly installed.  
All appliances are shipped from the factory  
equipped for conventional negative draft venting.  
All other optional vent systems require the  
installation of specific vent kits and venting  
materials. See the Installation and Service Manual  
for a detailed explanation of the installation  
requirements for each venting system, components  
used and part numbers of vent kits for each model.

The combustion air supply must be completely free of any  
chemical fumes which may be corrosive to the appliance.  
Common chemical fumes which must be avoided are  
fluorocarbons and other halogenated compounds, most  
commonly present as refrigerants or solvents, such as  
Freon, trichlorethylene, perchlorethylene, chlorine, etc.  
These chemicals, when burned form acids which quickly  
attack the heat exchanger finned tubes, tube headers, flue  
collectors, and the vent system. The result is improper  
combustion and a non-warrantable, premature appliance  
failure.

Cycle appliance and check for proper operation.  
An appliance installed in a dust or dirt contaminated  
atmosphere will require cleaning of the burners on a 3 to 6  
month schedule or more often, based on severity of  
contamination. Contaminants can be drawn in with the  
combustion air. Non-combustible particulate matter such  
as dust, dirt, concrete dust or dry wall dust can block burner  
ports and cause non-warrantable failure Use extreme care  
when operating an appliance for temporary heat during  
new construction. The burners and fan will probably  
require a thorough cleaning before the appliance is placed  
in service.  
The three setting knobs on the temperature control are for  
Set point, Differential, and High-Fire Offset (see Figure 5).  
6. Combustion Air Fan: The combustion air fan should be  
checked every 6 months. Clean as required when  
installed in a dust or dirt contaminated location.  
7. Water Circulating Pump: Inspect pump every 6 months  
and oil as necessary. Use SAE 30 non-detergent oil or  
lubricant specified by pump manufacturer.

Maximum Set Point Determination  
8. Keep appliance area clear and free from combustible  
materials, gasoline and other flammable vapors and  
liquids.  
The maximum set point for the control is factory set.  
Boilers can be set to 240°F max., water heaters are set to  
190°F max., and specialty state and local codes to 200°F.  
These maximum set points are established by cutting the  
OJ1 and OJ2 jumpers located on the right side of the  
temperature controller. The maximum set point is  
determined as shown below in TABLE-B.

Set Point  
Shutdown  
The Set Point knob specifies the target water temperature  
in degrees, Fahrenheit. After the water temperature reaches  
the set point, the temperature control shuts off the burners.  
The Shutdown knob specifies the outdoor air lockout  
temperature at which the control would prevent the  
appliance from operating.  
Differential  
Outdoor Air Max (O.A. Max)  
The Differential specifies the number of degrees below the  
set point that the control will allow the water temperature  
to drop before it brings the appliance back on again.  
The O.A. Max knob allows a reset up to the maximum  
outdoor air temperature specified by this knob setting. At  
any outdoor air temperature above the specified setting, the  
appliance will not reset but will continue to run at the set  
point temperature.  
High-Fire Offset  
The temperature control operates a two-stage firing system.  
The two stages are High-Fire and Low-Fire. High-Fire  
operates all burners while Low-Fire operates  
approximately one-half of the burners.  
Ratio  
The Ratio knob allows control over the reset ratio to be  
used during Outdoor Air Reset. The allowable ratios are as  
low as 0.5:1 or as high as 1.5:1.  
The High-Fire knob specifies the number of degrees below  
set point that the High-Fire stage shuts down. At that point,  
the appliance will continue to operate at the Low-Fire stage  
until the set point is reached.  
Selecting the 0.5:1 ratio will increase the set point 0.5°F for  
every 1.0°F drop in outdoor air temperature up to the  
maximum set point temperature.  
The High-Fire offset knob has settings between 0°F and  
20°F. If set at 0°F, the High-Fire offset is disabled and the  
appliance will operate at the High-Fire stage until the set  
point is reached and the temperature control shuts the  
appliance off.  
Selecting the 1.5:1 ratio will increase the set point 1.5°F for  
every 1.0°F drop in outdoor air temperature up to the  
maximum set point temperature.  
No matter what the High-Fire offset knob is set to, the  
appliance will light at Low Fire and operate for  
approximately 10 to 120 seconds before the High-Fire  
stage actuates.  
See Figure 7 for an outdoor air reset chart example.  
OUTDOOR AIR RESET OPTION  
Outdoor Air Reset Option  
For boilers ordered with the Outdoor Air Reset option,  
there is an additional control (FIG. 6). There are three
