CHEMICAL VAPOR CORROSION
Corrosion of the flueways and vent system may occur if air for
combustion contains certain chemical vapors. Such corrosion may
result in failure and risk of asphyxiation.
Spray can propellants, cleaning solvents, refrigerator and air
conditioning refrigerants, swimming pool chemicals, calcium
and sodium chloride (water softener salt), waxes, and process
chemicals are typical compounds which are potentially corrosive.
Do not store products of this sort near the heater. Also, air which is
brought in contact with the heater should not contain any of these
chemicals. If necessary, uncontaminated air should be obtained
from remote or outside sources. The limited warranty is voided
when failure of water heater is due to a corrosive atmosphere. (See
limited warranty for complete terms and conditions).
WATER PIPING
HOTTER WATER CAN SCALD:
Water heaters are intended to produce hot water. Water heated to
a temperature which will satisfy space heating, clothes washing,
dish washing, cleaning and other sanitizing needs can scald and
permanently injure you upon contact. Some people are more likely
to be permanently injured by hot water than others. These include
the elderly, children, the physically or developmentally disabled. If
anyone using hot water fits into one of these groups or if there is a
local code or state law requiring a certain temperature water at the
hot water tap, then you must take special precautions. In addition
to using the lowest possible temperature setting that satisfies your
hot water needs, a means such as a mixing valve should be used
at the hot water taps used by these people or at the water heater,
INSTALLATION REQUIREMENTS
18
see Figure 9. Valves for reducing point of use temperature by
mixing cold and hot water are also available:
Consult a Qualified Installer or Service Agency. Follow
manufacturer's
instructions
Before changing the factory setting on the thermostat, read the
Temperature Regulation section in this manual.
This water heater shall not be connected to any heating
systems or component(s) used with a non-potable water heating
appliance.
All piping components connected to this unit for space heating
applications shall be suitable for use with potable water.
Toxic chemicals, such as those used for boiler treatment shall
not be introduced into this system.
When the system requires water for space heating at
temperatures higher than required for domestic water purposes,
a mixing valve must be installed. Please refer to Figure 9 for
suggested piping arrangement.
These water heaters cannot be used in space heating
applications only.
POWER SUPPLY
The water heaters covered in this manual require a 120
VAC, 1Ø (single phase), 60Hz, 5 amp power supply and
must also 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.
If any of the original wire as supplied with the water heater must
be replaced, it must be replaced with 105°C rated wiring or its
equivalent, except in the burner housing. In this case 200°C rated
wire must be used.
