ELECTRICAL WIRING

NOTE: If it is necessary to replace any of the original wiring, it must be replaced with 105° C wire or its equivalent, and/or 150° C wire or its equivalent as originally built.

MILLIVOLT SYSTEM

The Millivolt System residential heater is equipped with a self-generating electrical system in which the electric current is provided by means of a pilot generator. No external electrical connections are required.

When installing a remote switch, do not exceed 10 feet of wiring from the heater. Use 18 gage stranded wire.

ELECTRONIC

INTERMITTENT IGNITION DEVICE SYSTEM (IID)

NOTE:

Heaters are factory wired for 240V power supply.

The standard field wiring connection is on the right side of the heater.

To wire the heater from the left side, follow the steps below:

1.Remove the two (2) screws that hold down the junction box to the sway brace. Untie excess yellow wires located behind the junction box.

2.Move the junction box to the left side of unit and attach the box to the sway brace.

3.Secure 24V yellow wires to sway brace panel with existing wire retainers.

4.Connect the wires inside the junction box, either 120V or 240V depending on the field wiring.

NOTE: 7/8" Dia. holes not utilized on jacket and control box can be used for fireman switch or auxiliary control interface wiring.

NOTE: Heater must be electrically grounded and bonded. Bonding lug is provided loose with the unit. Install bonding lug on lower right or left side of jacket as necessary for bonding the unit. Mounting hole is provided on the jacket.

The Electronic Intermittent Ignition Device automatically lights the pilot and main burners upon a call for the heat. The heater is supplied with a dual voltage transformer for 120V or 240V input power hookup.

P-R185B To P-R405B, C-R185B To P-R405B, P-R185BL To P-R405BL, C-R185BL To C-R405BL, RP2100 specifications

Raypak offers a comprehensive line of boilers and water heaters, notably the P-R185B to P-R405B and C-R185B to P-R405B series, along with the RP2100 model. These products are engineered for efficiency, reliability, and performance in both residential and commercial applications.

The P-R185B to P-R405B series features a range of input capacities from 185,000 to 405,000 BTU/h, making them suitable for various heating requirements. The P-R series is equipped with Raypak's patented Cupro-Nickel heat exchanger, which offers superior corrosion resistance and extended life in challenging water conditions. These units also utilize a sealed combustion system, allowing for efficient operation and reduced energy consumption by drawing air from outside the building.

The C-R185B to P-R405B boilers are specifically designed for commercial applications where reliability is critical. They incorporate similar features to the standard P-R series and are built to handle higher heating demands, making them ideal for larger facilities. The C-R series models are recognized for their durable construction and advanced control systems, offering precise temperature management and enhanced performance.

In addition to these series, the P-R185BL to P-R405BL and C-R185BL to C-R405BL models feature a low-NOx design to comply with stringent environmental regulations. This means they produce lower nitrogen oxides, making them an environmentally friendly option without sacrificing performance.

The RP2100 is another standout model, known for its robust design and cutting-edge technology. It boasts a high efficiency rating and is equipped with an intuitive digital control system, allowing users to monitor and adjust settings with ease. The RP2100 also features a modulating burner system, which adjusts the flame based on the heating demand, optimizing fuel usage and minimizing operational costs.

All Raypak models are designed with safety in mind, incorporating multiple safety features like thermal shutdowns and pressure relief valves. Their compact dimensions make installation straightforward, and the low maintenance requirements ensure longevity and consistent performance.

In summary, Raypak's P-R185B to P-R405B, C-R185B to P-R405B, P-R185BL to P-R405BL, and RP2100 series represent a commitment to quality and innovation in heating solutions, providing efficient and reliable options for both residential and commercial applications.
