IMPORTANT
READ ALL OF THE FOLLOWING WARNINGS
AND STATEMENTS BEFORE READING THE
INSTALLATION INSTRUCTIONS
WARNING
SEE "WARNING" ON PAGE 4 FOR LIQUEFIED
PETROLEUM (L.P.) PROPANE GAS-FIRED BOILERS
The installation must conform to the requirements of the
authority having jurisdiction or, in the absence of such require-
ments, to the National Fuel Gas Code, ANSI Z223.1-lates
edition. The installation must also conform to the additional
requirements in this Slant/Fin Instruction Book.
In addition, where required by the authority having jurisdic-
tion, the installation must conform to American Society of
Mechanical Engineers Safety Code for Controls and Safety
Devices for Automatically Fired Boilers, No. CSD-1. If there
is any conflict in the above requirements, then the more
stringent requirement will apply.
This manual must be left with owner and should be hung
on or adjacent to the boiler for reference.
WARNING
This boiler, gas piping and accessories must be installed,
connected, serviced and repaired by a trained, experienced
service technician, familiar with all precautions required for
gas-fired equipment and licensed otherwise qualified, in
compliance with the authority having jurisdiction.

Page 17: Boiler Room Air Supply And Ventilation
Sentinel BOILER ROOM AIR SUPPLY AND VENTILATION An ample supply of air is required to obtain combustion and ventilation. ALL AIR COMES FROM OUTSIDE, directly through wall openings to the boiler or through unsealed open- ings around windows, doors, etc. in the whole building. When buildings are insulated, caulked and weather stripped, now or later on, direct openings to outside may be required and should be provided. - Page 18 Sentinel Figure 11.
