RELIEF VALVE

 

￿ WARNING

 

 

 

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.

￿CAUTION

Avoid contact with hot discharge water.

VENT SYSTEM OPTIONS

This appliance has five venting options. They are:

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.

3.Direct Venting with Sidewall Terminations Direct vent with sidewall terminations for flue products and combustion air.

4.Direct Venting with Vertical Terminations Direct vent with vertical through-roof terminations for flue products and combustion air.

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.

IMPORTANT:

Examine the venting system at least once a year. Check all joints and vent pipe connections for tightness. Also check for corrosion or deterioration. Immediately correct any problems observed in the venting system.

COMBUSTION AND VENTILATION AIR

REQUIREMENTS FOR

CONVENTIONALLY VENTED

APPLIANCES

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.

￿CAUTION

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.

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.

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.

E+ Vent and Direct Vent Units

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.
