BEFORE INSTALLATION
Raypak strongly recommends that this manual be re-
viewed thoroughly before installing your ADB heater.
Please review the General Safety information before
installing the heater. Factory warranty does not apply
to heaters that have been improperly installed or oper-
ated. (Refer to the warranty at the back of this
manual.) Installation and service must be performed
by a qualified installer, service agency or gas supplier.
If, after reviewing this manual, you still have questions
which this manual does not answer, please contact the
manufacturer or your local Raypak representative.
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. 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 and 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 rating plate located on
the left inside jacket of the heater. The model number
will have the form H4-0751A ADB or similar depending
on the heater size and configuration. The first charac-
ter of the model number identifies application (H =
Hydronic Heating System, W = Hot Water Supply
System, P = Pool Application). The second character
identifies the firing mode (4 = On-Off firing). The next
four places identify the input of the heater in 1,000s of
BTUH 0751 = 750,000 BTUH). The remaining suffix
identifies the control, ignition, and construction config-
uration. The last three characters of the model number
identifies the model type (ADB = Advanced Design
Boiler).

All Raypak heaters are National Board Approved, and
design-certified and tested by the Canadian Standards
Association (CSA) for the U.S. and Canada. Each
heater is constructed in accordance with Section IV of
the American Society of Mechanical Engineers
(ASME) Heater Pressure Vessel Code and bears the
ASME stamp. The heater also complies with the latest
edition of ASHRAE 90.1 Standard.
WARNING: Altering any RAYPAK pressure vessel
by installing replacement heat-exchangers, tube
bundle headers, or any other ASME part not
manufactured and/or approved by RAYPAK will
instantly void the ASME, and agency listings and any
RAYPAK warranty on the vessel. Altering the ASME,
agency ratings of the vessel also violates national,
state, and local approval codes. The terms "boiler"
and "heater" are used interchangeably in this
manual.
Installations at Elevation
No de-rating is required for altitudes up to 7000 feet.
Rated inputs, at sea level settings, are suitable for up
to 5000 feet elevation. At altitudes between 5000 and
7000 feet, rated inputs are achieved with pressure set-
tings adjustment. Consult the factory for installations at
altitudes in excess of 7000 feet.
