THE INSTALLATION OF THE REMAINDER OF THE GAS CONTROLS IS DEPENDENT ON THE CONTROL
SYSTEM FURNISHED.
REFER TO THE TABLE BELOW FOR THE FIGURES IN THIS MANUAL APPLICABLE
TO THE VARIOUS CONTROL SYSTEMS OFFERED AS STANDARD OR AS OPTIONAL EQUIPMENT. IF THE
CONTROL SYSTEM ORDERED IS NOT LISTED, SPECIAL INSTRUCTIONS HAVE BEEN PREPARED BY THE
APPLICATION ENGINEERING DEPARTMENT AND CAN BE FOUND IN THE INSTRUCTION ENVELOPE
FURNISHED WITH THE BOILER.

Open Gas Controls Carton(s)
NOTE: On those boilers with two manifolds (15 sect. and larger), two identical sets of Gas Controls are furnished. Hence,
the procedure for installing one set is equally applicable to the second set.
ground joint union, as show in Fig. 1, should be
installed in the piping to each gas train for ease of
servicing.
CONNECT GAS SERVICE FROM METER TO GAS
TRAIN in accordance with the requirements of the
authority having jurisdiction or, in the absence of such
requirements to the –
USA – “National Fuel Gas Code, ANSI Z223.1”.
CANADA – “Installation Codes for Natural and LP Gas
Burning Appliances and Equipment, CAN/B149.1 &
.2”.
The size of the gas train(s) has no criteria as to the size
of the service from the meter to the gas train(s). Sizing
of the service is dependent on:
a. Required supply of gas in cu. ft./hr.
input of boiler in BTUH
= heat value of gas,
BTU/cu. ft.
b. Allowable loss of pressure in piping to obtain
minimum input pressure indicated on rating label of
boiler.
c. Length of piping in feet and number of elbows – for
practical purposes each 90º elbow can be considered
as the following equivalent in length of straight
pipe:
3/4”
-
2.1 ft.
2” - 5.2 ft.
1”
-
2.6 ft.
2-1/2” - 6.2 ft.
1-1/4”
-
3.5 ft.
3” - 7.7 ft.
1-1/2”
-
4.0 ft.
4” - 10.1 ft.
d. Specific gravity of gas
In the absence of requirements of the authority
having jurisdiction, the tables below may be used to
size natural gas supply piping.
A pipe thread compound resistant to the action
of liquefied petroleum gases must be used on all
threaded joints in the gas piping.
Pressure testing of the Gas Supply Piping Boiler and
its connections is required before placing the boiler
in operation.
The boiler and shutoff valve must be disconnected
from the gas supply piping system during any
pressure testing at pressures greater than ½” psig.
The boiler must be isolated from the gas supply
piping system during any pressure testing at
pressures equal to or less than ½ psig.
