BEFORE INSTALLATION
Raypak strongly recommends that this manual be
re-viewed thoroughly before installing your XTherm
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
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
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
warranty 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
warranties.
Model Identification
The model identification number and heater serial
number are found on the heater rating plate located on
the upper rear jacket panel of the heater. The model
number will have the form H7-2505 or similar depend-
ing on the heater size and configuration. The letter(s)
in the first group of characters identifies the application
(H = Hydronic Heating, WH = Domestic Hot Water
(DHW), P = Pool). The number which follows identi-
fies the firing mode (7 = electronic modulation). The
second group of characters identifies the size of the
heater (the four numbers representing the approxi-
mate MBTUH input), and, where applicable, a letter,
indicating the manufacturing series.

Installations at Elevation
Rated inputs are suitable for up to 2,000 ft elevation
without de-rating. Consult your local representative or
the factory for installations at altitudes over 2,000 ft
above sea level. No hardware changes are required
to the heaters for installations up to 10,000 ft (adjust-
ments may be required).
WARNING:
Altering any Raypak pressure vessel by
installing replacement heat exchangers, tube bundle
headers, or any ASME parts not manufactured and/
or approved by Raypak will instantly void the ASME
and CSA ratings of the vessel and any Raypak
warranty on the vessel. Altering the ASME or CSA
ratings of the vessel also violates national, state, and
local approval codes.
