BEFORE INSTALLATION
Raypak strongly recommends that this manual be re-
viewed thoroughly before installing your XFyre 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
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
n
umber are found on the heater rating plate located on
the upper rear jacket panel of the heater. The model
n
umber will have the form H7-850 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, W = Hot Water). The number
which follows identifies the firing mode (7 = electronic
modulation). The second group of characters identifies
the size of the heater (three numbers representing the
approximate MBTUH input), and, where applicable, a
letter, indicating the manufacturing series.

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 “H” stamp. This heater also complies with the
latest edition of the ASHRAE 90.1 Standard.
Installations at Elevation
Rated inputs are suitable for up to 2000 ft elevation
without de-rating. Consult your local representative or
the factory for installations at altitudes over 2000 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 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.
WARNING: Pump motors should NOT be
supported by any type of stand or support from
above due to possible misalignment of pump and
motor which may occur.
