Combustion Air and Venting
SECTION II - Providing Air for Combustion and Ventilation
WARNING
The installer must provide adequate combustion and ventilation to the area in which the ELITE is installed. Providing adequate air ensures proper combustion and reduces the potential risk of severe personal injury or death from carbon monoxide emissions if a flue gas leakage occurred.
WARNING
The installer should not install an exhaust fan in the room with the ELITE. The exhaust fan could affect the combus- tion of the burner or cause potential flue gas leakage resulting in severe personal injury or death.
NOTICE
The installer should take the condition and age of the building when determin- ing air for ventilation. Older building (buildings with single pane windows and minimal
The installer must follow the requirements of state, provincial or local codes when sizing and locating adequate air openings for combustion and ventilation.
In absence of the codes the installer may opt to use the following guidelines when the ELITE is installed in a confined room as defined by NFPA 31 as a room with less than 7200 cubic feet per 1 GPH of input of all appliances locat- ed in the area (7200 cubic feet is define as a room with 8 foot ceiling and 33.5 ft x 33.5 ft in dimension):
Two Permanent Openings - One opening must commence within 12 inches of the ceiling and the other opening within 12 inches of the floor. The opening must have a minimum height or length dimension of 3 inches, the actual dimensions are based on:
Using Inside Air - Each opening must be con- nected freely to the areas having adequate infil- tration from the outside. Each opening should be at least 140 sq. inches per 1 GPH of input (1 sq. inch per 1000 BTU input). This input should include all appliances (gas and/or oil) plus any appliances that may draw air from the room such as clothes dryers.
Using Outside Air - Each opening should be connected directly or by ducts to the outdoors or to a crawl space or attic area that is freely connected with the outdoors. The openings should be sized as follows:
Through outside wall or vertical ducts -
The openings should be a minimum 35 sq inches per 1 GPH input (1 sq. inch per 4000 BTU input) of all appliances (gas and/or oil) plus any appliances that may draw air from the room such as clothes dryers.
Through horizontal ducts - The openings should be a minimum 70 sq. inches per 1 GPH input (1 sq. inch per 2000 BTU input) of all appliances (gas and/or oil) plus any appliances that may draw air from the room such as clothes dryers.
Where ducts are used, the size of the duct should equal the free area of the opening in which the duct is connected to.
7
Combustion Air and Venting
The installer should compensate for any lou- vers, grilles or screens when determining the free air of the opening. The installer should refer the louver or grille manufacturer???s instruction for determining free area. In absence of the manufacturer???s instructions the installer should use the following as a guide- line:
-Wood louvers will provide 20 to 25% free area
-Metal louvers or grilles will provide 60 to 75% free air
Installers should lock louvers in the open posi- tion or provide an interlock system to prove the louvers are in the open position prior to opera- tion of the ELITE.
Removal of an Existing Boiler from a Common Vent System
BEST PRACTICES
For installations in which the ELITE is replacing an existing boiler / hot water heater system, which was connected to a common vent system with other appli- ances, the following steps shall be con- ducted with each remaining appliance connected to the common venting system:
1.Any unused openings in the common venting system must be sealed.
2.A visual inspection of the venting sys- tem must be conducted for proper siz- ing and horizontal pitch. The inspec- tion should ensure no blockage or restriction is within the vent system, and there is no leakage, corrosion or other items, which could cause an unsafe condition.
3.To adequately test the venting system, close all exterior doors and windows and all doors between the area contain- ing the remaining appliances connected to the common vent system and other areas of the building. Turn on any clothes dryers and any other gas appli-
ance not connected to the common vent system. Turn on all exhaust fans, i.e. range hoods and bathroom exhaust fans, preferably at maximum speed. Close any fireplace dampers.
4.Place in operation the first appliance being inspected that is connected to the common vent system. The remaining appliances should not be in operation. Follow the appliance???s lighting instruc- tions and adjust the thermostat to allow the appliance to operate continuously.
5.Test for spillage at the draft hood relief opening after 5 minutes of main burner operation. Spillage can be detected using the flame of a match or candle or with smoke from a cigarette.
6.Once it has been determined that each remaining appliance connected to the common vent system is properly vent- ed, return doors, windows, exhaust fans, fireplace dampers and any oper- ating gas appliance to their previous condition.
Should any improper operation of the common venting system be detected in the outlined test, the condition should be corrected so the vent system conforms with the National Fuel Gas Code, NFPA 54/ ANSI Z223.1 - latest edition. Canadian installations must conform with B149.1 or 149.2 Installation Code.

Domestic Piping
SECTION IV - Domestic Piping
General Piping Requirements
???All plumbing must meet or exceed all local, state and national plumbing codes.
???Use pipe dope or tape suitable for potable water.
???Use isolation valves to isolate system components.
???Install unions for easy removal of the ELITE from the system piping.
Domestic Supply Pressure
For applications in which the domestic sup- ply pressure exceeds 70 psig it is recom- mended to install a pressure reducing valve on the cold water supply.
Maintaining the cold water supply at or below 70 psig will prevent normal thermal expansion from repeatedly forcing the T&P relief valve open.
Thermal Expansion
If the cold water supply contains a backflow preventer, check valve and / or a pressure reducing valve, the installer must install a domestic thermal expansion tank on the cold water supply. (See Fig. 2 page 14)
Installing a thermal expansion tank will prevent normal thermal expansion from repeatedly forcing the T&P relief valve open.
When installing a thermal expansion tank ensure the charge pressure of the tank is equal to the cold water supply pressure at the point of installation. Consult the ther- mal expansion tank manufacturer???s instruc- tions for further information on installation and sizing.
CAUTION
The Temperature / Pressure relief valve is not intended for constant duty, such as relief of pressure due to normal thermal expansion.
Water Hammer
Water hammer is the effect of sudden pres- sure changes occurring in the domestic pip- ing. These pressure changes are typically the result of ???fast acting??? positive
The effects of water hammering can cause damage to system components and tank welds on the unit.
Installation of hammer arresters is recom- mended at these types of appliances, which incorporate
Temperature / Pressure Relief Valve
The ELITE has a factory installed Temperature / Pressure Relief valve. Ensure the rating of the T&P relief valve is correctly sized as follows per AGA:
11
Domestic Piping
The installer must install discharge piping onto the T&P relief valve. The discharge piping must be:
???Made of material serviceable for tem- peratures of 250??F or greater.
???Directed so that any hot water dis- charge flows away from all persons.
???Directed to a suitable place of drainage.
???Installed as to allow complete draining of the T&P relief valve and the dis- charge piping.
???Terminated with a plain end, not with threads.
WARNING
DO NOT install any valves between the T&P relief valve and the discharge pip- ing. DO NOT plug the T&P relief valve or the discharge piping. Improper place- ment and piping of the T&P relief valve can cause severe personal injury, death or substantial property damage.
Thermostatic Mixing Valve
The ELITE contains a factory installed thermo- static mixing valve with
The operating range of the thermostatic mixing is 90??F to 120??F.
CAUTION
Failure to properly direct the discharge piping of the T&P relief valve may result in flooding of the area adjacent to the unit and or lower floors in the structure causing substantial property damage.
The installer must not install the T&P relief valve discharge piping in a manner that is:
???Excessively long: Using more than 2 elbows and/or 15 feet of discharge pip- ing can reduce the discharge capacity.
???Terminated directly into a drain: The discharge piping must terminate within 6 inches of the drain. Check with local plumbing codes for termination guide- lines.
???The discharge piping is plugged, reduced in size or restricted in any manner.
???The discharge piping is subject to freez- ing.
For applications with a domestic recirculation loop, the recirculation pump should be con- trolled by an aquastat. The maximum recom- mended setting of the aquastat is 10??F lower than the thermostatic mixing valve setting.
DANGER
For proper operation of the thermostatic mixing valve and to prevent potential scalding hazards, the recirculation loop should be controlled by an aquastat. DO NOT use continuous recirculation.

Primary System Piping Applications
BEST PRACTICE
All piping applications shown in this instal- lation manual utilize a primary/ secondary piping arrangement. This method is rec- ommended as a means to provide priority to the production of domestic hot water. For other piping arrangements, consult the Engineering Department at Triangle Tube or consult other approved/recognized design arrangements.
BEST PRACTICE
On piping applications utilizing a single zone or other recognized piping design arrangements it is recommended the installer uses flow/check valves with weighted seats at or near the appliance to prevent gravity circulation.
Expansion Tank and Makeup Water
Ensure the expansion tank is properly sized for the outer tank volume (22 gallons) and the system volume and temperature.
CAUTION
Undersized expansion tanks will cause sys- tem water to be lost through the pressure relief valve and cause additional makeup water to be added to the system. Eventual primary tank failure can result due to this excessive makeup water addition.
The expansion tank must be located as shown in Fig. 7, 7A or 7B page 20 or as per recognized design methods. Refer to the expansion tank manufacturer instructions for additional installation details.
Connect the expansion tank to an air sepa- rator only if the air separator is located on the suction side (inlet) of the system circu- lator. Always locate and install the system fill connection at the same location as the expansion tank connection to the system.
Diaphragm (Bladder) Expansion Tank
Always install an automatic air vent on the top of the air separator to remove residual air from the system.
It is recommended to pitch any horizontal piping toward the expansion tank 1 inch per 5 feet of piping. Use 3/4??? piping for the expansion tank to allow air within the sys- tem to rise.
For proper operation of the expansion tank and system, remove the factory installed automatic air vent from the ELITE and plug the connection. (See Item 10, Fig. 28 page 50)
