Size gas Piping.
Design system to provide
adequate gas supply to boiler. Consider these factors:
1. Allowable pressure drop from point of delivery to
boiler. Maximum allowable system pressure is ½
psig. Actual point of delivery pressure may be less;
contact gas supplier for additional information.
Minimum gas valve inlet pressure is indicated on
Rating Label, located on the vestibule panel.
2. Maximum gas demand. Table 2 lists boiler input
rate. Also consider existing and expected future gas
utilization equipment (i.e. water heater, cooking
equipment).
Table 2: Rated Input
jurisdiction specifies a gravity factor be applied. For
specific gravity greater than 0.70, apply gravity
factor from Table 5. If exact specific gravity is not
shown choose next higher value.
For materials or conditions other than those listed
above, refer to the
National Fuel Gas Code
, NFPA
54/ANSI Z223.1 and/or CAN/CGA B149
Installation Codes, or size system using standard
engineering methods acceptable to authority having
jurisdiction.

Connect boiler gas valve
to gas supply system.
1. Use methods and materials in accordance with local
plumbing codes and requirements of gas supplier. In
absence of such requirements, follow the
National
Fuel Gas Code
, NFPA 54/ANSI Z223.1 and/or
CAN/CGA B149 Installation Codes.
2. Use thread (joint) compounds (pipe dope) resistant
to action of liquefied petroleum gas.
3. Install sediment trap, ground-joint union and manual
shut-off valve upstream of boiler gas valve and
outside jacket. See Figure 29.
3. Length of piping and number of fittings. Refer to
Table 3 for maximum capacity of Schedule 40 pipe.
Table 4 lists equivalent length for standard fittings.
4. Specific gravity of gas. Gas piping systems for gas
with a specific gravity of 0.70 or less can be sized
directly from Table 3, unless authority having
Figure 29: Recommended Gas Piping
