DO NOT
use this water heater as a replacement for an existing boiler installation.
DO NOT
use with piping that has been treated with chromates, boiler seal or other chemicals.
DO NOT
add boiler treatment or any chemicals to any heat piping, since the piping contains potable water.
DO NOT
use with ferrous piping. The system should be installed only with new piping that is suitable for potable water,
such as copper or polybutylene.
DO NOT
use with PVC piping.
DO NOT
use any pumps, valves, or fittings that are not completely compatible with potable water piping.
DO NOT
use valves that may cause excessive restriction to water flow.
USE FULL BLOW BALL OR GATES VALVES ONLY.
DO NOT
tamper with the thermostat, gas valve, igniter control or temperature and pressure relief valve. Tampering
with any of these componets is DANGEROUS and can result in property damage or severe injury. Tampering avoids all
warranties. Only qualified personnel should service these components.
DO NOT
use 50/50 solder in potable water lines.
IF THE SPACE HEATING system requires water temperature in excess of 120ºF, a mixing valve or other means should be
installed in the domestic
(potable)
hot water supply to limit the RISK OF SCALD DAMAGE
(See PAGE A).
Some jurisdictions may require a backflow preventer in the incoming cold water line. This may cause the temperature
and pressure relief valve on the water heater to discharge or weep due to expansion of the heated water. A diaphragm-
type expansion tank suitable for potable water will normally eliminate this weeping condition. Please read and follow the
manufacturer’s instructions for the installation of such tanks.
