ured to operate in an on-off firing mode. This means that you will connect a single-pole control to stage one of the CPW board. Then jumper the remaining firing stages. For example, if your heater is a Model 1532B, you will jumper stages two, three and four. Then your heater will either be on at full fire, or it will be off.

2.For 2-stage controller connections, connect each stage of the control to the corresponding stage of the CPW board in the heater, i.e., stage 1 of the heater to stage 1 of the control; stage 2 of the heater to stage 2 of the control, as shown in Fig. 22 and Fig. 25. Set the operating control to the set-point at which you want the heater to maintain. Ensure that the sensing bulb of the control is at the point in the system that will best maintain the tem- perature you want. For example, when you are heating a tank of water, you want the operating control sensor bulb in the tank.

3.For single-stage controller connections, attach the stage 1 connections on heater 1 to the tankstat per Fig. 26.

Heater must be electrically grounded in accordance with the NEC, and CSA C22.1 C.E.C. Part 1 in Canada.

Consult the wiring diagram shipped with the heater in the instruction packet or at the end of this section. The stage-selector terminals are for the remote tank con- trol through the heater’s 24 VAC transformer. DO NOT attach any voltage to the stage-selector terminals. Before starting the heater, check to ensure proper volt- age to the heater and pump.

NOTE: If any of the original wire supplied with the heater must be replaced, it must be replaced with similar sized 105°C wire or its equivalent.

NOTE: For 87%-efficiency boilers, see special instructions on page 43.

CAUTION: Proper installation of flue venting is criti- cal for the safe and efficient operation of the heater.

General

Flue Exhaust Tee

An optional Flue Exhaust Tee is available to facilitate horizontal venting. Any reference to horizontal venting that exits the back of the heater requires this tee. Refer to Table J for the appropriate kit for your model.

Appliance Categories

Heaters are divided into four categories based on the pressure produced in the exhaust and the likelihood of condensate production in the vent.

Category I – A heater which operates with a non-pos- itive vent static pressure and with a vent gas temperature that avoids excessive condensate pro- duction in the vent.
