6 START-UP PROCEDURE
1. When placing the unit into operation, open relief valve to purge air from top of tank and begin to fill the tank with
cold water. Check for plumbing leaks. Be sure the tank is completely filled before closing the relief valve.
CAUTION: Do not energize the heater or circulating pump until the tank is full of water. Serious damage may result.
2. Push control switch, located on the control box, to “ON” to activate the three-way valve and thermostats. Check
the valve for operation; the valve actuator motor should “run” to open the valve when operating switch is pushed
“ON”. Check operating thermostat settings.
Temperature Setting: The operating thermostat is set at the factory at approximately 120°F and the upper
operating thermostat (if supplied) is set at approximately 130°F. Adjustment may be made by turning the
thermostat’s dial to the desired temperature. The temperature limiting device is factory set at 200°F.
CAUTION: Gradually introduce fluids to the unit. Failure to do so can cause damage to the heat exchanger.
3. Push the operating switch to “OFF” before opening manual main boiler water supply valve. Do not admit boiler
water to the unit suddenly when empty or cold to prevent thermal shock. Gradually open boiler water supply valve
until all passages of the heat exchanger are filled. Slowly bring the unit up to temperature.
WARNING: Do not operate unit under conditions in excess of those specified on nameplate and ASME data
plate. Failure to operate the heat exchanger within the specified design pressure and temperature may
result in damage to the heat exchanger, property damage, personal injury or loss of life.
4. Open nearby hot water tap to maintain a flow of water through the tank when starting up units. Regulate flow of
water through the tank to allow the control valve to cycle off and on, and check operation of all safety and
operating controls.
5. In all installations, there should be no pulsation or water hammer since this causes vibration and strain with
resulting leaks.
6. Retighten bolting on all gasketed joints after the heat exchanger has reached temperature to prevent leaks and
gasket failures. Retightening should be done uniformly and in a diametrically staggered pattern (see
“Maintenance” for proper torque specs).
a. On high pressure and high temperature applications or any application where spiral wound gaskets are
required, it is recommended that the gasketed joints of the heat exchanger be retightened to the required
torque (see “Maintenance”) after 24 hours at operating pressures and temperatures to compensate for any
relaxation or creep that may have occurred.
b. In shutting down, remove all power from the system. Close all boiler water and cold water supply valves to the
unit.
c. If the unit is removed from service for an extended period of time, it must be drain completely to eliminate the
possibility of freezing and corrosion from stagnant water conditions.
