T&P Relief Valve Discharge Piping
T&P relief valve discharge piping must be:
- made of material serviceable for tempera­tures of 250ºF or greater.
- directed so that hot water flows away from all persons.
- directed to a suitable place for disposal.
- installed so as to allow complete draining of the T&P relief valve and discharge line.
T&P relief valve discharge piping must not
be:
- excessively long. Using more than 2 elbows or 15 feet of piping can reduce dis­charge capacity.
- directly connected to a drain. Terminate discharge piping within 6” from drain. Refer to local codes.
- plugged, reduced or restricted.
- subject to freezing.
Do not install any valve between T&P relief valve and tank connection or on T&P relief valve discharge piping. Do not plug T&P relief valve or discharge piping. Improper placement and piping of T&P relief valve can cause severe personal injury, death or substantial property damage.
Drain Valve

Water Heater Start-Up
Filling the Inner (Domestic Water) Tank
Never use water heater unless inner and outer tanks are completely filled with water.
Inner tank must be completely filled and pressurized before pressurizing outer tank.
1. Close domestic water drain valve.
2. Open domestic water isolation valves for water heater.
3. Vent air from inner (domestic water) tank by opening nearest hot water faucet. Fill domestic water tank completely by allowing water to run until there is a constant flow of water.
4. Close hot water faucet.
Filling the Outer (Boiler Water) Tank
Never use water heater unless inner and outer tanks are completely filled with water.
Inner tank must be completely filled and pressurized before pressurizing outer tank.
1. Close boiler water drain valve at boiler water outlet of water heater.
2. Open water heater’s boiler water isolation valves.
3. Allow air to escape from outer (boiler water) tank by opening vent cap A on automatic air vent, located on top of water heater. See Fig.
19.
4. Follow instructions furnished with boiler to fill with water.
5. When tank is full, air will stop escaping, and the automatic air vent will close. If air vent does not seat properly (water leaks out), remove cap A. Briefly push in valve B and release it to clean valve seat. Screw cap A on completely, then unscrew one turn. See Fig. 19.
For proper operation of the water heater, always leave vent cap unscrewed one full turn.
6. If antifreeze is used in boiler water, check concentration. Boiler water (including addi­tives) must be practically non-toxic, having toxicity rating or class of 1, as listed in Clinical
Toxicology of Commercial Products.
Do not use automotive, ethylene glycol or petroleum-based antifreeze. Do not use any undiluted antifreeze. This can cause severe personal injury, death or substantial property damage.

HOT WATER CAN SCALD!
•Water temperatures over 125ºF can cause severe burns instantly, or death from scalds.
Feel water before bathing or showering.
Consumer Product Safety Commission and some states recommend temperatures settings of 130ºF or less. Setting thermostat higher than 130ºF will increase risk of scald injury and cause severe personal injury or death.
•Water heated to a temperature suitable for clothes washing, dish washing and other sanitiz­ing needs will scald and cause permanent injury.
•Children and elderly, infirm, or physically handicapped persons are more likely to be injured by hot water. Never leave them unat­tended in or near a bathtub. If anyone using hot water in the building fits this description, or if state laws or local codes require certain water temperatures at hot water faucets, take special precautions.
- Install an automatic mixing valve at water heater or at each hot water faucet, bath and shower outlet. Selection and installation must comply with valve manufacturer’s recommendation and instructions.
- Use the lowest practical temperature setting.
- Check water temperature after any adjust­ment. You must follow “Adjusting the Water Heater Thermostat” procedures.
General Notes
Household water usage patterns will affect water temperature at any faucet or shower. Occasionally check temperature at each point of use, then adjust thermostat accordingly. Always recheck temperature after adjusting thermostat.
When hot water is used in repeated small quan­tities, a “stacking” effect can develop in the water heater. The upper layer of water in tank can be hotter than lower layer.
Lowering the thermostat setting or installing automatic mixing valves as indicated in these instructions will reduce water temperature levels. Consult your installer or service technician.
At no time should boiler limit control be set above 210ºF. This can cause severe person­al injury, death or substantial property damage if ignored.

Adjusting the Water Heater Thermostat
Water heater thermostat is factory set to its lowest temperature. This may or may not be suitable for your needs.
Turn thermostat knob clockwise to increase water temperature. Turn thermostat knob counter-clockwise to decrease water temperature.
Studies have indicated that dangerous bac­teria, including legionella, pneumophila, can form in the potable water distribution sys­tem if certain minimum water temperatures are not maintained. Contact your local health department for more information.
Check water temperature at a hot water faucet immediately after first heating cycle. Further temperature adjustment may be necessary as water heating system is used. Recheck water temperature at faucet after adjustment.
When adjusting thermostat, be sure boiler limit control is set a minimum of 20ºF higher.

Water Heater Maintenance
Maintenance Schedule
Annual service by qualified service technician should include the following:
Any procedure required by local codes.
Check air vent operation.
Verify system pressure. Air venting proce­dure may require adding water to bring sys­tem up to pressure, typically 12 psig.
Manually operate T&P relief valve at least once a year. This will release some hot water.
Before operating T&P relief valve, make sure no one is in front of or around T&P relief valve discharge piping. Hot discharge water can cause severe personal injury or substantial property damage.
Move operating lever to open position for a few seconds and then move it back, allowing it to snap closed. After T&P relief valve is oper­ated, if it continues to release water, close cold water inlet to water heater immediately. Follow draining instructions, and replace T&P relief valve. If T&P relief valve weeps period­ically, it may be due to thermal expansion see Thermal Expansion, page 5. Do not plug T&P relief valve or discharge piping.
Plugging T&P relief valve or discharge pip­ing can cause excessive pressure in water heater, resulting in severe personal injury, death, or substantial property damage.
Follow instructions on circulator to oil it, if required.
Check mixing valve, valves, pipes and fit­tings for leaks.
Check function of field-installed controls and valves. See component manufacturer’s instructions.
Review homeowner’s maintenance responsi­bilities and their frequencies, including any not listed in the following section.
Homeowner monthly maintenance to include:
Check air vent operation.
Automatic air vent - remove cap. Briefly
push in valve and release it to clean valve seat. Screw cap on completely, then unscrew one full turn. If air vent does not operate, call qualified service technician.
Visually check valves, pipes and fittings for leaks. Call qualified service technician to repair leaks.
Filling Water Heater
See “Filling the Inner (Domestic Water) Tank and “Filling the Outer (Boiler Water) Tank” on page 20.
Draining Water Heater
Drain water heater if it will be shut off and exposed to freezing temperatures. Freezing water will expand and damage water heater.
If boiler water contains sufficient
antifreeze, then only the domestic water needs to be drained.
Close boiler water isolation valves and relieve system pressure to below 15 psig in outer tank before draining inner tank to prevent damage to inner tank.
If boiler water does not contain sufficient
antifreeze, then the boiler water and domestic water must be drained.
If antifreeze is used in boiler water, check concen­tration. Boiler water (including additives) must be practically non-toxic, having toxicity rating or class of 1, as listed in Clinical
Toxicology of Commercial Products. A maximum 50/50 mixture of inhibited propylene glycol is recommended. Follow antifreeze manufacturer’s instruction.
