T&P Relief Valve and Pipe Insulation.
(Only Models with insulation material included in the package)
1. Locate the T&P Relief Valve on the Water Heater.
2. Locate the slit running the lenght of the insulation.
3. Spread this slit open and slip it over the T&P Relief Valve (See Figure 10). Apply gentle pressure to the insulation to
ensure it is fully seated on the T&P Relief Valve. Once sealed secure the insulation with a section of tape. IMPORTANT: The
insulation or tape should not block or cover the T&P Relief Valve drain opening. Also the insulation or tape should not block
or cover the T&P Relief Valve opening. Also the insulation or tape should not block or hinder access to the T&P Relief Valve
relief lever.
4. Next locate the hot water (outlet) & cold water (inlet) pipes to the water heater.
5. Spread the slit open at the base of the insulation and slip it over the cold water (inlet) pipe. Apply gentle pressure along
the length of the insulation to ensure it is fully seated around the cold water pipe. Also ensure that the base of insulation is
flush with the water heater. Once seated, secure the insulation with a section of tape.
SPACE HEATING/POTABLE WATER SYSTEM
Sine water heater models are equipped with inlet/outlet tapping for use with space heating applications. If this water heater
is to be used to supply both space heating and domestic potable
(drinking)
water, the instructions listed below must be
followed.
• Be sure to follow the manual(s) shipped with the air handler system.
• A properly installed flow control valve is required to prevent thermo-siphoning. Thermo-siphoning is the result of a
continuous flow of water through the air handler circuit during the off cycle.
• Weeping (blow off) of the temperature and pressure relief valve (T & P) or higher than normal water temperatures
are the first signs of thermo-siphoning.
• The domestic hot water line from the water heater should be vertical past any tempering valve or supply line to
the air handle to remove air bubbles from the system. Otherwise, these bubbles will be trapped in the air handler
heat exchanger coil, reducing efficiency.
