3 - BEFORE INSTALLATION
Raypak strongly recommends that this manual be reviewed
thoroughly before installing your XPak boiler. Please review the
General Safety information before installing the boiler. Factory
warranty does not apply to boilers 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 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 boiler it is suggested that you visually check
for external damage to the shipping package. If the package is
damaged, make a note to that effect on the Bill of Lading when
signing for the shipment. Remove the boiler 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 indicated 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
Raypak 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 boiler. 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 defective replacement parts will not be
accepted and will be replaced in kind only per Raypak’s standard
warranty.
Model Identification
The model identification number and boiler serial number are
found on the boiler rating plate located on the casing right side.
Also the boiler serial number can be found on the back page of this
manual and inside the front control panel flap.
TIME/TEMPERATURE
RELATIONSHIPS IN SCALDS
The following chart details the relationship of water temperature
and time with regard to scald injury and may be used as a guide
in determining the safest water temperature for your applications.
Water Time to Produce Serious
Temperature Burn
120°F More than 5 minutes
125°F 1-1/2 to 2 minutes
130°F About 30 seconds
135°F About 10 seconds
140°F Less than 5 seconds
145°F Less than 3 seconds
150°F About 1-1/2 seconds
155°F About 1 second

The temperature of the water in the boiler can be regulated by
using the Raypak Remote Control REC08. To comply with safety
regulations, the control is set when shipped from the factory.
CAUTION
: Hotter water increases the risk of scalding! There
is a hot water scald potential if the thermostat is set too high.
2 - GENERAL SAFETY
To meet domestic hot water use needs, the high limit safety control
on this boiler is adjustable up to 140°F (60°C).Water temperatures
over 125°F (50°C) can cause instant severe burns or death from
scalds.
When supplying general purpose hot water, the recommended
initial setting for the temperature control is 125°F (50°C).
Safety and energy conservation are factors to be considered
when setting the water temperature on the thermostat. The most
energy-efficient operation will result when the temperature setting
is the lowest that satisfies the needs of the application.
Water temperature over 125°F (50°C) can cause instant severe
burns or death from scalds. Children, disabled and elderly are at
highest risk of being scalded.
• Feel water before bathing or showering.
• Temperature limiting valves are available.
NOTE
: When this boiler is supplying general purpose hot
water 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.
Maximum water temperatures occur just after the boiler’s burner
has shut off. To determine the water temperature being delivered,
turn on a hot water faucet and place a thermometer in the hot
water stream and read the thermometer.
WARNING
: This boiler cannot supply hot water for use by
individuals directly. A heat exchanger must be used in
conjunction with this boiler to meet DHW needs.
