Caution:
This boiler requires forced water circulation when burner is operating. See minimum and maximum flow rates.
Severe damage will occur if the boiler is operated without proper water flow circulation. A flow switch is used to ensure
that water flows through the boiler, but does not check for the minimum flow rate into the boiler. Numbers are
approximate and may vary depending on installation. See Chart below.

1-1 Pre-Installation
Ajax strongly recommends that this manual be reviewed thoroughly before installing your Atlas High Efficiency
Condensing 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 in chapter 8). Installation and
service must be performed by a qualified installer, service agency or gas supplier. If, after reviewing this manual, you still
have questions not covered in this manual, please contact the manufacturer or your local Ajax representative.
Product Receipt
On receipt of the unit, visually inspect for external damage to the shipping crate or unit. If the crate or unit 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 and inspect the unit internally. Report all damages and missing or incorrect parts to the carrier and supplier
immediately. Claims for damages must be filed with the carrier by the consignee. Permission to return goods must be
received from the factory prior to shipping. Goods returned to the factory without an authorized Return Goods
Authorization number will not be accepted. Ajax Boiler Inc. is not responsible for any damage that the unit receives while
in shipping. As each shipping company has its own procedure for filing a claim, please contact the shipper for claim
instructions.
Model Identification
Your Atlas Series Condensing Boiler carries two identification plates: The coil identification plate, which carries the ASME
Code Stamping and Registration Number (when applicable) is attached to the water inlet, with a duplicate on the heat
exchanger top plate. The unit’s nameplate is located on the right side of the rear panel of the unit, and lists information
concerning the input and output of the unit, electrical and gas ratings, working pressure and clearance to adjacent
construction figures. In addition the model and serial numbers are on the plate. You will need these to order replacement
parts from the manufacturing representative in your area or from the factory.
The information on the National Board plate is the same as on the nameplate with the exception of the
National Board registration number, which is required in most states for installation of the unit.
Do not remove any of these plates from the unit for any reason. Removal of these plates will void the warranty.
