Appliance regulators must not be used as line gas pressure
regulators to step down the gas pressure. For additional
information regarding gas regulator selection and installation
consult your regulator manufacturer, any applicable local
codes or ordinances, the standard for line pressure regulators
ANSI Z21.80/CSA 6.22, and The National Fuel Gas Code NFPA
54/ANSI Z223.1.
Gas Piping Installation
Adhere to the following for gas piping installation:
1. See Table 3 for required natural gas pipe size, based on
overall length of pipe from the meter plus equivalent
length of all fittings. Approximate sizing may be based
on 1,020 BTU for 1 cubic foot of natural gas. See Figures
6 and 7 for piping arrangements.
2. Install a manual gas shutoff valve and union (not
supplied) prior to the boiler.
3. Piping must be installed such that no piping stresses
are transmitted to the boiler. The boiler cannot be used
as a pipe anchor.

Notes:
1. Required for installation with greater than
28"W.C. (14"W.C. Canada) inlet pressure, field
supplied.
GAS SUPPLY
2. Required 10 pipe diameters equivalent to the
regulator connection size. This pipe must be
straight, uninterrupted pipe between regulator
outlet and and any fittings, valves, or elbows.
3. The line regulator should be installed with a
minimum of 10 linear feet of pipe between the
regulator outlet and boiler fuel train inlet.

ENDURA SINGLE BOILER GAS SUPPLY
PIPING
4. All gas piping connections must be pressure-tested and
SHEET 1 OF 1
checked for leaks before being placed into service. Test
with compressed air or inert gas if possible.
5. The boiler gas train must be disconnected at the boiler
manual shutoff valve from the gas supply piping system
during any pressure testing of the system at pressures
in excess of 1.0 psig (28 inch W.C.).
6. Gas Piping must be installed in accordance with
National Fuel Gas Code, ANSI Z223.1 1991 or latest
addenda and any other local codes, which may apply.
7. The pipe and the fittings used must be new and free of
dirt or other deposits.
8. Piping must be of the proper size to ensure adequate
gas supply. It is typical for gas delivery piping to be up-
sized one or several diameters larger than boiler gas
inlet size.
9. Connect gas supply line to the open end of the tee on
which the drip leg is installed.
