Applies to: Models LDAP, UDAP, APD, UDAS,

UDBP, UDBS, UEAS, F, B, VR

Description/

Application

These options are designed to permit the control of up to six heaters (one "Primary" heater

and one to ve "Secondary" units; see note for LDAP limitations) with one single-stage ther-

mostat or with a time clock and single or multiple single-stage thermostats. For maximum

safety, the multiple control is done in the low voltage circuit. (Interruption of the supply volt-

age is not recommended.) Wiring lengths may not exceed those shown in the table on page

8. DO NOT use these multiple heater control options with a two-stage gas valve or a

two-stage thermostat.

FIGURE 1A - Control Compartment showing Transformer Location, Models UDAP, APD, UDAS, and

UEAS "Primary" Heater

The transformer is mounted on the control board on the bottom of the control compartment.

These instructions are designed to assist a qualied electrician in installing this multiple

heater control kit. All electrical wiring and connections, including electrical grounding,

MUST be in accordance with the National Electric Code ANSI/NFPA No. 70 (latest edi-

tion) or, in Canada, with the Canadian Electrical Code, Part 1-C.S.A. Standard C22.1 In

addition, the installation must comply with local ordinances and applicable gas company

requirements.

Follow the instructions that apply to the option and model of heater.

1. Turn off the gas and electric power.

2. Change the Transformer (does not apply to Model LDAP, UDBP, or UDBS) –

applies to OPTION CL31 installation on the "Primary" unit only

Refer to the illustration (FIGURE 1A, 1B, or 1C) for the unit being serviced.

Remove or open panels as required and locate the factory-installed transformer.

Mark and disconnect the wires. Remove the transformer.

Using the same screws (except Models F and B; see FIGURE 1C), install the 35 or

40 VA transformer from the kit. Connect the wires. Close the panel.

On the end of the burner/control box, remove and

discard the screws holding the thermostat terminal strip.

Use the screws and spacers in the option package to

attach the relay bracket and to re-attach the terminal

strip. Follow the sequence below, starting at the burner/

control box

- rst the terminal strip,

- second the spacers,

- third the relay bracket,

- and fourth (on the left side only) – put the blue and

brown wires through the plastic cable clamp and

position the cable clamp on top of the relay bracket.

FIGURE 2D - Model F or B

On the rear of the heater, remove the screws

that hold the thermostat terminal strip. Slide

the relay bracket underneath the terminal strip.

Re-insert the screw on the right side. Put the

blue and brown wires into the plastic cable

clamp, and on the left end of the terminal strip,

position the cable clamp on top. Fasten with the

other screw.
