Inspect the incoming water line for check valves or water pressure reducing valves. Any type of check valve may cause pressure to build up in the heater and cause tank failure. If the heater is installed in a closed system or if backflow pre- venters and pressure regulators are installed, add an expansion tank. Do not try to heat hard water. Install a water softener if the heater is being used in a hard water area (water hardness more than 7 grains).
An approved temperature and pressure (T&P) relief valve is factory installed in the opening provided in the upper right hand side of the heater. Pipe the T&P to within 6" of the floor or to a floor drain with a free flowing drain pipe. Do not install a check valve in the cold water line.
Using “L” or “A” type venting, connect the heater to the chimney. Use the same size smoke pipe as the heater flue pipe (on models 20e, 20pp, 32E, 32PP and 33E, you may use 4" with a reducer if needed).
WARNING: On Models 40E, 5OES, 50ESC, 51E, 51EC, 51PP, 51PPC. 71E and 120E, do not reduce the smoke pipe diameter. Run a separate smoke pipe from the water heater to the chimney wherever possible.
If it is necessary to tee into an existing smoke pipe, be sure the connector being teed into is large enough to accommodate the products of combustion of all units attached to it. When teeing into another connector, run in at 45° angle (see Figure 1). Install a draft regulator control only if necessary. Overfire draft should not be positive. Stack draft should be
The oil burner is equipped with a primary relay. An aquastat with immersion well is packed with the burner. The thermostat is factory set at 120°F for residen- tial use (see caution on page 1 regarding temperature variations). Install the immersion well with the aquastat and check the bulb length (see “Burner & Controls” section, page 10).
Remove the cardboard core from the burner opening. Mount the burner on stud bolts and place the gasket (supplied) between the burner flange and the heater. Secure the burner to the heater with 1/4
All wiring must comply with applicable codes and ordinances. The primary relay is wired to the burner at the factory. Install the aquastat well in the 3/4" tapping at the front of the heater. Be sure the sensing bulb is inserted all the way into the well. For Honeywell aquastats, tighten the screw on top of the aquastat to secure the control to the well. For Carlin
