RECEIVING EQUIPMENT
On receipt of your equipment it is suggested that you
visually check for external damage to the carton. If the
carton is damaged, it is suggested that a note be made
on the Bill of Lading when signing for equipment.
Remove the heater from the carton and if it is dam-
aged report the damage to the carrier immediately. Be
sure that you receive the number of packages indicat-
ed on the Bill of Lading. Claims for shortages and
damages must be filed with carrier by consignee.
Purchased parts are subject to replacement only
under the manufacturer's warranty. Debits for defec-
tive replacement parts will not be accepted and
defective parts will be replaced in kind only per our
standard warranties.
When ordering parts, you must specify Model and
Serial Number of the heater. When ordering under
warranty conditions, you must also specify date of
installation.
Raypak recommends that this manual be reviewed
thoroughly before installing your Raypak heater. If
there are any questions which this manual does not
answer, please contact your local Raypak representa-
tive.
GENERAL
SPECIFICATIONS
The Raypak water heaters are design certified by the
and tested under the requirements of the American
National Standard, ANSI Z21.10.3. Each heater has
been constructed and pressure tested in accordance
with the requirements of Section IV of the American
Society of Mechanical Engineers Code, and factory
fire tested.
These heaters are designed for indoor and outdoor
installations, and can be installed on combustible floor-
ing when the appropriate listed floor shield base is
used.
Models are available with standing pilot or with inter-
mittent ignition device (IID), and are equipped with the
following components as standard: water circulation
pump, pressure relief valve, manual reset high limit
switch, flow switch, vent thermal and flame roll-out
switches (except for models 330 and 400), a solid
state Economaster pump control relay, 40VA trans-
former, and redundant combination gas valve for use
with either Natural or Propane gases. A tankstat is
supplied loose for installation in the field.
DANGER: There is a Hot Water SCALD Potential if
the tankstat is set too high.
CAUTION: Hotter water increases the risk of
SCALDING!
NOTE: When this heater is supplying general
purpose hot water requirements for use by
individuals, a thermostatically controlled mixing
valve for reducing point of use water temperature is
recommended to reduce the risk of scald injury.
Contact a licensed plumber or the local plumbing
authority for further information.
