Before You Start - Dunkirk PWXL Installation, Operation & Maintenance Manual

Check to be sure you have the right size boiler before starting the
installation. See rating and capacity table on previous page. Also be
sure the new boiler is for the type of gas you are using. Check the
rating plate on the right side of the boiler.
You must see that the boiler is supplied with the correct type of gas,
fresh air for combustion, and a suitable electrical supply. The boiler
must be connected to a suitable venting system and an adequate pip-
ing system. A thermostat, properly located, is needed for control of
the heating system. If you have any doubts as to the various require-
ments, check with local authorities. Take the time to complete all of
the steps for SAFE and PROPER operation of the heating system.
If this boiler is installed in a building under construction, special
care must be taken to insure a clean combustion air supply during
the construction process. Airborne particulates such as from dry-
wall dust and from fiberglass insulation can clog the burner ports,
flueway passages and cause incomplete combustion and sooting.
Where required by the authority having jurisdiction, the installation
must conform to American Society of Mechanical Engineers Safety
Code for Controls and Safety Devices for Automatically Fired Boil-
ers, No. CSD-1.
