Installation Of The Aquastat (Temperature Control)

This heater operates automatically under the control of the aquastat, which responds to the demand of hot water. Depending on the model, the aquastat well and wiring is either installed on the heater, or included in the carton con- taining the burner. If the installation of the aquastat is required, proceed as follows:

1.Locate the aquastat well opening in the front of the heater.

2.Apply a good grade of pipe joint compound to the threads on the well.

3.Install the well in the tank opening, tighten firmly to ensure there are no leaks.

4.Insert the sensing bulb of the aquastat into the well and secure the aquastat to the well using the screw provid- ed.

5.Wire the control to the burner as shown in the wiring dia- grams (Figures 9, 10 & 11).

Electrical Supply

General wiring requirements:

Electric shock hazard. Can cause severe personal injury or death if power source, including service switch on heater, is not disconnected before installing or servicing. Installations must comply with the latest editions of these codes:

Canadian Electrical Code Part 1 (CSA C22.1)” (Canada).

“National Electrical Code, ANSI/NFPA 70”, (USA).

Any additional local, provincial, national or state codes. Wiring must be N.E.C. Class 1. If original wire supplied with the heater is to be replaced, TYPE 105°C wire or equivalent must be used. Supply wiring to heater and additional control wiring must be 14 GA. or heavier. Provide an electrical ground as required by codes.
