BEFORE INSTALLATION
Raypak strongly recommends that this manual be re-
viewed thoroughly before installing your Hi Delta
heater. Please review the General Safety information
before installing the heater. Factory warranty does not
apply to heaters that have been improperly installed or
operated (refer to the warranty at the back of this man-
ual). Installation and service must be performed by a
qualified installer, service agency or the gas supplier.
If, after reviewing this manual, you still have questions
which this manual does not answer, please contact
your local Raypak representative or visit our website at
www.raypak.com.
Thank you for purchasing a Raypak product. We hope
you will be satisfied with the high quality and durability
of our equipment.
Product Receipt
On receipt of your heater it is suggested that you visu-
ally check for external damage to the shipping crate. If
the crate is damaged, make a note to that effect on the
Bill of Lading when signing for the shipment. Next,
remove the heater from the shipping packaging.
Report any damage to the carrier immediately.
On occasion, items are shipped loose. Be sure that
you receive the correct number of packages as indi-
cated on the Bill of Lading.
Claims for shortages and damages must be filed with
the carrier by consignee. Permission to return goods
must be received from the factory prior to shipping.
Goods returned to the factory without an authorized
Returned Goods Receipt number will not be accepted.
All returned goods are subject to a restocking charge.
When ordering parts, you must specify the model and
serial number of the heater. When ordering under war-
ranty conditions, you must also specify the date of
installation.
Purchased parts are subject to replacement only
under the manufacturer’s warranty. Debits for defec-
tive replacement parts will not be accepted. Parts will
be replaced in kind only per Raypak’s standard war-
ranties.
Model Identification
The model identification number and heater serial
number are found on the heater data plate located on
the left inside jacket of the heater. The model number
will have the form H3 0162 or similar depending on the
heater size and configuration. The first character of the
model number identifies application (H = Hydronic
Heating System, WH = Hot Water Supply System, P =
Pool Application). The second character identifies the
firing mode (3 - two stage firing, 4 - On/Off firing ). The
next four places identify the size of the heater.
