
The boiler comes from the factory
ready to be piped to the gas supply.
The National Fuel Gas Code, ANSI
Z223.1/NFPA 54 and local codes
for gas piping requirements and
sizing must be followed.

Install a manual gas shutoff valve
and drip leg as shown in Figure 12.
Figure 12 - Gas supply
piping
The gas supply piping to the boiler
must be properly sized to guarantee
that the gas supply meets the
maximum requirements. If more
than one appliance is supplied by
the same gas supply pipe, the gas
supply piping must be sized based
on the maximum possible demand.
Do not neglect the pressure drop due
to pipe fi ttings. Table 1 below, should
be used in conjunction with Table 2
below, to ensure that the gas supply
piping is sized properly. See section
14 for values of “maximum gas supply
pressure” and “minimum gas supply
pressure” and also section 11.7.

Before installation a thorough
internal cleaning of the gas supply
line should be performed. Figure
9 shows the positioning of the gas
connection on the heater.

The boiler and its gas connection
must be leak tested before placing
the boiler in operation.

To avoid damaging the gas control,
perform a leak test at a pressure
of no greater than 20 in W.C.
(50
mbar) .
WARNING!!! Never use an open
fl ame to test for gas leaks. Always
use an approved leak detection
method. Failure to comply with
this WARNING could result in an
explosion!

The boiler and its individual shutoff
valve must be disconnected from
the gas supply piping during any
pressure testing at test pressures in
excess of 1/2 psi (
3.5 kPa) .

The boiler must be isolated from
the gas supply piping by closing
its individual manual shutoff valve
during any pressure testing at test
pressures equal to or less than 1/2
psi (
3.5 kPa) .

Install 100% lockup gas pressure
regulator in supply line if inlet
pressure can exceed 13”W.C. at
any time. Adjust lockup regulator
for 13”W.C. maximum.

Use pipe sealing compound
compatible with propane gas. Apply
sparingly only to male threads of
the pipe joints so that pipe dope
does not block gas fl ow.
5.14- Propane gas
WARNING!!! These boilers
are typically shipped ready to fi re on
natural gas. Check boiler rating plate
to determine which fuel the boiler is
set for. If set to natural gas, it may
be converted to LP by following the
instructions in Section 5.17. Failure
to comply could result in severe
personal injury, death, or substantial
property damage.
Pipe sizing for propane gas
Contact gas supplier to size pipes,
tanks and 100% lockup gas pressure
regulator.
Propane supply pressure
requirements:
1. Adjust propane supply regulator
provided by the gas supplier for
13”W.C. maximum pressure.
2. Pressure required at gas valve
inlet port:
a. Maximum 13”W.C. with no fl ow
(lockup) or with boiler on.
b. Minimum 3”W.C. with gas
fl owing (verify at high fi re).
WARNING!!! Ensure that the
high pressure gas regulator is at least
6-10ft upstream of the appliance.
5.15 - Operating at
high altitudes
For installations in the United States,
the boiler is rated for operation at
altitudes up to 2,000 ft (609 m). For
installations at higher altitudes in
the United States, follow local codes
or, in the absence of local codes,
follow ANSI Z223.1/NFPA No. 54,
The National Fuel Gas Code . For
installations in Canada, the boiler is
rated for installations up to 2,000 ft
(609 m). For installations above this
altitude, follow local/provincial codes.
