Phase III ®
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.
WARNING
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.
Installation
Commonwealth of Massachusetts Installation
• Insert an open-end dip tube into the Auxiliary connection on top of water heater.
• Install a 3/4” NPT elbow to the Auxiliary connection (Figure 3).
• Pipe the drain piping with drain valve from the elbow connection to:
a suitable place for disposal or
terminate within 12” of the floor

2. Install 1/2” x 1/8” reducer bushing provided with water heater, using suitable pipe dope or tape.
3. Install automatic air vent provided with water heater, using suitable pipe dope or tape.
4. Unscrew vent cap on air vent one full turn. Leave cap unscrewed one turn for normal venting.
Thermal Expansion
If a backflow preventer, check valve or pressure reducing valve is piped on cold water supply piping of water heater, install an expansion tank on cold water supply line to prevent normal thermal expansion from repeatedly forcing open T&P relief valve.
CAUTION
Drain Valve
Drain valve and fittings are supplied by others.
Standard Installation
• Install a tee connection at the domestic cold water inlet (Figures 1 and 2 pages 8 and 9).
• Pipe the drain piping with drain valve from the tee connection to:
a suitable place for disposal or
terminate within 12” of the floor
T&P relief valve is not intended for constant duty, such as relief of pressure due to repeated normal system expansion. Correct this condition by installing a properly sized expansion tank in domestic water system.
Refer to expansion tank manufacturer’s installation instructions for proper sizing.

DANGER
®
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.
Water Heater Start-Up
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.
WARNING
At no time should boiler limit control be set above 210ºF. This can cause severe personal injury, death or substantial property damage if ignored.

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.
WARNING
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
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.
See “Filling the Inner (Domestic Water) Tank and
“Filling the Outer (Boiler Water) Tank” on page 20.
Draining Water Heater
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.
DANGER
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.
23
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.
WARNING
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.
Phase III
WARNING
®
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.
WARNING
Water from opened drain valves, unions and other connections may be extremely hot. To avoid severe personal injury, death or substantial property damage:
- Tighten all drain hose connections.
- Direct hot water away from all persons.
Draining Inner (Domestic Water) Tank
(See Domestic Piping Fig. 1 page 8)
1. Disconnect power supply to water heater.
If outer (boiler water) tank pressure is greater than 15 psig, relieve boiler pressure and close isolation valves before proceeding.
Water Heater Maintenance
2. Close system supply isolation valve.
3. Connect a hose to domestic water drain valve at cold water inlet. Hose should extend to drain at floor level to allow siphoning of domestic water tank.
4. Open hot water faucet at highest point above heater.
5. Open domestic water drain valve to start siphoning.
6. When draining is complete, close hot water faucet and domestic water drain valve.
Draining Outer (Boiler Water) Tank
1. Disconnect power supply to water heater.
2. Close boiler water isolation valves between boiler and water heater.
3. Connect hose to boiler water drain valve at water heater. Open and drain water to a safe place.
4. To speed draining procedure, loosen air vent on top of tank.
