INSTALL CONTROLS AND TRIM
3.Mount the High Limit Control bulb well in the left side 3/4" tapping of the coil cover plate if a tankless heater is not mounted in the upper right opening (Position 2). If a coil is installed there, mount the well in the 3/4" tapping to the left of the opening. See Figure 8.2.
CAUTION
Make sure that the gas ignition system components, electrical controls, junction boxes and electrical panels are protected from water (dripping, spraying, rain, etc.) during boiler operation and service (circulator or pump servicing, control replacements or other).
E.PIPE TANKLESS HEATERS IF USED
1.Connect piping to any installed tankless heaters. See Figure 8.3 for suggested piping for single coils and Figure 8.4 for suggested piping for dual coils.
F.CONNECT SUPPLY WIRING
1.Install all wiring in accordance with local codes, the National Electrical Code and other controlling agencies or governing bodies.
2.Use #14 gauge or heavier wire for supply wiring. Protect the circuit with a fused disconnect switch (by others).
CAUTION
The boiler/burner must be electrically grounded in accordance with the requirements of the authority having jurisdiction, or in the absence of such requirements, with the current edition of the National Electrical Code, ANSI/NFPA Number 70.
3.Follow the instructions in the Burner Manual and the Wiring Diagrams supplied with the burner and the boiler.
G.INSTALL CONTROL WIRING
1.Wire the boiler according to the wiring diagrams supplied with the burner and the boiler (in the Boiler Envelope).
2.Low Energy Safety Control wiring, if used, must follow the contour of the boiler. Some local codes may require that all wiring, even low voltage, be routed in conduit.
3.Install line voltage wiring in conduit.
4.Do not install single pole switches, including safety controls, in a grounded line.
