THE CONTROLLER TO MALFUNCTION. A HIGH QUALITY POWER
CONDITIONER MUST BE INSTALLED IF THE ABOVE CONDITIONS EXIST.
MALFUNCTIONS CAUSED BY A POOR ELECTRICAL SUPPLY ARE NOT
COVERED UNDER YOUR WARRANTY.
The controller is wired to the heater as shown in Figure 15. The model and
rating plate provides the electrical information needed to size the complete
heater branch supply.
All electrical work must be installed in accordance with the Canadian Electrical
Code, CSA C22.1 and local requirements.
When installed, the appliance must be electrically grounded in accordance
with local codes or, in the absence of local codes, with the Canadian Electrical
Code, CSA C22.1.
DO NOT ENERGIZE THE BRANCH CIRCUIT BEFORE THE HEATER TANK
IS FILLED WITH WATER.
NOTE: This controller is Polarity Sensitive. If the Hot and Neutral Supply
Voltage is reversed, the controller will not sense flame. Verify polarity before
connecting the unit.
3. This unit may never be connected to any existing heating system or
component(s) previously used with non-potable water heating
appliance.
4. When the system requires water for space heating at temperatures higher
than required for domestic water purposes, a tempering valve must be
installed. Please refer to installation diagrams on pages 23 through 28 in

EQUIVALENT, EXCEPT IN THE BURNER HOUSING. IN THIS CASE USE
200°C WIRE.
THE COMPUTER CONTROL REQUIRES A SOURCE OF STABLE CLEAN
ELECTRICITY FOR PROPER OPERATION. INSTALLING THE HEATER
ON A BRANCH CIRCUIT THAT HAS ELECTRONIC NOISE, IS SUBJECT
TO FLUCTUATIONS IN VOLTAGE LEVEL OR HAS AN APPLIANCE
WHICH GENERATES EMF OF RFI INTERFERENCE CAN CAUSE
