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 National
Electrical Code, NFPA 70 or 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 National Electrical Code, ANSI/NFPA 70 or 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 back of manual for suggested piping arrangements.
HEATER WIRING
IF ANY OF THE ORIGINAL WIRE AS SUPPLIED WITH THE APPLIANCE
MUST BE REPLACED, IT MUST BE REPLACED WITH 105°C OR ITS
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 THE
CONTROLLER TO MALFUNCTION. A HIGH QUALITY POWER
