Pipe Sizing For Natural Gas; Propane Gas - RBI Infinite Energy2 IW199 Installation And Operation Instructions Manual

13 - INSTALLATION - Gas supply
13.2 - Pipe sizing
for natural gas
Refer to Figure 13-2 for pipe length
and diameter. For additional gas
pipe sizing information, refer to ANSI
Z223.1 (or B149.1 for Canadian
installations).
Natural gas supply pressure
requirements
1.- Pressure required at the gas valve
inlet pressure port:
• Maximum 13"W.C. with no flow
(lockup) or with appliance off.
• Minimum 3"W.C. with gas flowing
(verify during high fire).
2.- 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.

NOTICE! Maximum pipe capacity is based on a 0.60 specific gravity gas at a pressure of 0.5 PSIG and a
0.3"WC pressure drop

WARNING!!!
appliances are typically
shipped ready to fire on natural
gas. Check appliance rating
plate to determine which fuel
the appliance is set for. If
set to natural gas, it may be
converted to LP by following
instruction on Section 13.6 or
13.7. Failure to comply could
result in severe personal injury,
death, or substantial property
damage.

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 pressure port:
• Maximum 13"W.C. with no flow
(lockup) or with appliance off.
• Minimum 3"W.C. with gas flowing
(verify during high fire).
WARNING!!!
Ensure that
the high gas pressure regulator
is at least 6 - 10 ft upstream
of the appliance. Failure to
comply could result in severe
personal injury, death, or
substantial property damage.
