Test For Gas Pipe Leaks
Leaking gas could result in asphyxiation, explo-
sion, or fi re hazard.
•
The gas supply piping must be absolutely leak-free.
•
Pressure test the gas piping with air that is at least
three times greater than the gas pressure being
used.
•
Verify that there are no leaks before proceeding.
Clearances
With the burner installed in the appliance, there must be
adequate space in front of and on the sides of the burner
to allow access and operation. Verify that the clearance
dimensions comply with local codes and with the appli-
ance manufacturer's recommendations.
Fuel gas supply
Verify that the gas supply piping complies with all appli-
cable local codes and the latest edition of the National
Fuel Gas Code ANSI Z223.1 (NFPA 54).
Insure that the supply gas pipe size is capable of provid-
ing at least the minimum pressure required to the burner
gas train inlet at the burner's full capacity rating. Refer
to Table 1.
Flue vent system
The fl ue gas vent system must be in good condition and
must comply with National Fuel Gas Code ANSI Z223.1
(NFPA 54) and all other applicable codes having jurisdic-
tion for vent construction, capacity, and sizing.
Electrical supply
Check the nameplate on the burner to verify that the
power connections available are correct for the burner.
Refer to Figure 1. All power must be supplied through
fused disconnect switches and comply with the latest
edition of National Electric Code NFPA 70 (Canada CSA
C22.1) and all other local or applicable codes.
Verify burner components

Burner model can be checked from burner carton or
rating label on burner

•
Flange mounting arrangement (Includes high-tem-
perature gasket and /or fi ber rope for pressure fi r-
ing)
Verify fi ring input range
Refer to appliance manufacturer's instructions (if avail-
able) for the fi ring input range. Otherwise the maximum
recommended fi ring range for the burner depends on the
length and width of the fi ring chamber and the distance
from the burner center to the chamber fl oor. Verify that
the chamber dimensions are at least as large as the min-
imum values given in Figure 2. If the appliance dimen-
sions are smaller, reduce the fi ring rate accordingly.
NOTICE
Dimensions shown are for cast iron sectional boilers with
uptakes between sections. For minimum dimensions of
other furnace types consult R.W. Beckett Corporation.
